Verified point-by-point against the reworked plan.md: + +1. **Task 2.1.1c now targets only Go, via a real coc.nvim mechanism.** It removes `coc-go` from `g:coc_global_extensions` and adds `vim.api.nvim_create_autocmd("FileType", { pattern = "go", callback = function() vim.b.coc_enabled = false end })`. `b:coc_enabled` is coc.nvim's actual documented per-buffer disable variable — not a fabricated API. The task text explicitly rules out `g:coc_filetype_map` as the wrong mechanism ("that remaps one filetype's server config onto another's, it doesn't disable coc for a filetype"), which shows this was actually checked against coc.nvim's real behavior rather than guessed. `coc-rust-analyzer`, `coc-pyright`, `coc-tsserver` are explicitly called out as staying installed and functioning. +2. **Task 2.1.1d was split off** for the globally-safe removals (ale, Shougo/neco-* completion sources, vim-autoformat) — correctly reasoned as safe to remove atomically because none of them are filetype-scoped LSP clients competing with a not-yet-migrated language's coc extension. +3. **Phases 3/4/5 contain the corresponding per-language teardown tasks** — Task 3.1.1c (Rust), Task 4.1.1d (Python), Task 5.1.1c (TS/JS) — each gated behind "only after the smoke test passes," each with concrete Given-When-Then acceptance criteria checking `:checkhealth vim.lsp` shows exactly one client for the buffer plus `b:coc_enabled=false`/`g:coc_global_extensions` state. Task 5.1.1c additionally and correctly fully removes the `coc.nvim` plugin spec itself (TS/JS being the last language) and cleans up the now-dead per-filetype `b:coc_enabled` autocmds from the earlier tasks. +4. **The intermediate "Go migrated, others not yet" state has an explicit Given-When-Then.** Story 2.1.1's acceptance criteria contains: "*Given* Go has been migrated to native LSP in Phase 2 but Rust/Python/TS have not yet, *When* a `.rs`/`.py`/`.ts` file is opened, *Then* coc.nvim still attaches and provides LSP features for that filetype exactly as before, and `:checkhealth vim.lsp` shows zero active native clients for that buffer." This is exactly the missing acceptance criterion the original blocker asked for — no functional regression for not-yet-migrated languages is now a verified, not assumed, property. +5. **The Dependency Visualization diagram reflects the corrected sequencing**, not stale prose: Phase 2's box reads "2.1.1c: coc-go torn down only — coc.nvim STAYS installed for Rust/Python/TS/JS, per pitfalls.md §1," and Phases 3/4/5's boxes each show their own per-language teardown task, with 5's box noting the coc.nvim plugin spec is fully removed there (last language). +6. **Risk Control / Migration Plan narrative now matches the task-level reality.** The Migration Plan's cutover strategy explicitly sequences dogfooding per language "once a language's phase smoke test passes and its coc-teardown task lands (2.1.1c Go, 3.1.1c Rust, 4.1.1d Python, 5.1.1c TS/JS)." Risk Control gained two new bullets: "Staged rollout as staging" (states plainly that coc.nvim's teardown is per-language, tied 1:1 to each phase's native-LSP proof, and that coc.nvim legitimately keeps serving every not-yet-migrated filetype throughout Phases 2-4 as "a required, deliberate state, not an oversight") and "Master stays the daily driver for not-yet-migrated languages" (the explicit rule the iteration-1 blocker said was missing: real daily-driver work for a not-yet-migrated language stays on plain `nvim`/master until that language's own phase's coc-teardown task lands). No contradiction between "per-language" prose and "atomic" task language remains anywhere I could find (the old Risk Control sentence claiming atomic single-shot removal is gone). + +No new problem was introduced by the fix — Task 2.1.1c/2.1.1d's split is clean, the per-language teardown tasks in Phases 3-5 are consistent with each other in structure, and the final full-removal step is correctly placed only at the last language (5.1.1c) rather than duplicated or dangling. + +## Concerns +*(Carried forward unchanged from iteration 1 — independently re-checked against the current plan.md, none were incidentally addressed by the blocker fix or by the 4 architecture-review.md concerns fixed in the same pass. These remain CONCERNS, not blockers; they don't need to block progress.)* + +- [ ] **No task validates Mason install failure (network/rate-limit) on a fresh machine.** ux.md §4 and the "Auto-install UX" pattern decision cover the "not yet installed" case (mason `ensure_installed` turns it into a one-time self-healing event) but nothing tests or documents what happens when the install itself *fails* (offline, GitHub rate-limited, corporate proxy) — silent hang vs. a clear `vim.notify`/Mason UI error state. Given this is explicitly a cross-machine config (cfgcaddy sync), this failure surface is real, not hypothetical. — Add a smoke-test note/task (e.g. in Phase 7) exercising or at least documenting expected behavior with network disabled. +- [ ] **No task validates a genuine second-machine fresh cfgcaddy deploy before cutover.** Task 1.6.2a's empirical directory-vs-file check still uses `.claude/skills/` as a proxy, not `.config/nvim` itself, and every smoke test (2.3.2a, 3.1.1b, 4.1.1c, 5.1.1b, 7.4.1b) still runs on Tyler's single primary daily-driver machine. Cross-machine sync via cfgcaddy is named as a real external failure surface for this task, but the plan never dry-runs a true second-machine install (fresh Mason downloads, `rustup component add rust-analyzer`, treesitter `auto_install`, vimwiki path presence) before Story 7.4.1 declares done. — Add a second-machine (or disposable container) dry-run task in Phase 7 before the master merge. +- [ ] **Startup-time regression gate is still only concretely re-checked once, at the end of the Go pilot (Task 2.3.2a).** The Observability Plan states the gate should be checked "after each phase," but Phases 3-6's own smoke-test tasks (3.1.1b, 4.1.1c, 5.1.1b) still don't mention re-running `--startuptime` or comparing against baseline — only LSP/DAP functional checks. A regression introduced while adding rustaceanvim, basedpyright+ruff+debugpy, or vtsls could go undetected until Phase 7 (or past it, since Phase 7 also has no explicit final startup re-check task). — Add an explicit `--startuptime` comparison step to each phase's smoke-test task, not just Go's, and to the final cutover story. +- [ ] **No acceptance criteria for vimwiki/`~/personal-wiki` behavior when the directory doesn't exist on a given machine.** Story 7.2.1 still tests only the filetype-precedence race (mkd vs. vimwiki) and treesitter exclusion against real wiki files, never the "fresh machine without `~/personal-wiki/logseq/pages` yet" case implied by the cross-machine sync context. vimwiki likely degrades gracefully (lazily creates the path on first `:VimwikiIndex`) rather than erroring at startup, but this is assumed, not verified — and `wiki.lua` still loads vimwiki eagerly (`lazy = false`) for every buffer, so any startup-path error would be maximally disruptive. — Add a one-line acceptance criterion/test: fresh machine, no `~/personal-wiki` yet, `nvn` starts with zero errors. +- [ ] **No task/reminder addresses a future nvim point-release breaking the pinned treesitter `master` branch.** ADR-001 still pins nvim 0.11.6 + treesitter `master`, and pitfalls.md §3 documents that parser/query ABI drift after an nvim upgrade is a confirmed, recurring failure mode (worse on Manjaro's rolling-release cadence, this user's OS) — but nothing in the plan's cutover or maintenance notes tells future-Tyler to run `:TSUpdate` + the smoke-test checklist after the next `pacman -Syu` that bumps neovim. Reasonably out of *this* migration's scope, but a zero-cost documentation gap. — Add one line to the cutover checklist: "after any future nvim version bump, run `:TSUpdate` and re-run the smoke-test checklist before trusting highlighting." + +## Minors + +- Story 2.1.1 now bundles mason+lsp scaffolding, blink.cmp, per-language coc-Go teardown, and the global ale/coc-source removal across four tasks (2.1.1a/b/c/d, up from three in iteration 1 — c and d were usefully split apart by the blocker fix). The sub-tasks are small and independently testable, so bisection is feasible in practice, but the plan still doesn't say which to suspect first if something breaks after this story lands — worth a one-line note. +- Story 7.1.1's `.ideavimrc` change stays within the requirements' "minor cleanup, not a redesign" bound as written (leader + up to ~3 optional maps, "under ~6 lines"); worth enforcing that cap literally at implementation time so it doesn't creep. +- Task 2.3.1a's dap-ui auto-open/close behavior is shared/global logic that Rust (Phase 3) and Python (Phase 4) DAP configs will also depend on. When those phases touch this shared file, their smoke tests should include a quick Go DAP regression check, not just the new language's, to catch any accidental shared-state mutation (same class of risk the plan already avoids elsewhere via strict module separation). +- Technology bets (oil.nvim, lualine.nvim) reviewed: both are well-established, low-churn choices appropriate for a personal tool (lualine especially is close to a de facto standard), and their ADRs (003/004) already document rationale — no blocking concern. rustaceanvim's "not a drop-in swap" risk is explicitly acknowledged and handled (Pattern Decisions table, Task 3.1.1a's explicit "ensure rust-tools.nvim is absent" audit). The TS/JS DAP stretch goal (Story 5.1.2) is genuinely optional in the dependency graph — nothing in Phase 6/7 references it, and it's excluded from the requirements' DAP success metric (Go + Python only). +- Scope-drift cross-check against requirements.md's Out-of-Scope list found no violations: `.ideavimrc` change is bounded, no new Java/Ruby/Dart/Elixir investment (only pre-existing indent rules ported), Windows cfgcaddy entries are only *removed* (falls out naturally from the Linux/macOS cleanup, permitted), and wiki/writing plugins are explicitly ported "preserve, do not improve" (Task 1.7.5b) rather than upgraded. + +## Side note: architecture-review.md's 4 concerns +Independently spot-checked (not required for this pass, but observed while reading the diff): all 4 of architecture-review.md's concerns also appear resolved in the current plan.md — the `reserve()` helper now exists in Task 1.3.1a/Story 1.3.1 and is used by Task 2.3.1a's DAP keys; `leader_groups.lua` (Task 1.3.2b) is now the single source of truth consumed by both `keymaps.lua`'s comment (1.3.2a) and `which-key.lua`'s registration (1.4.1a); `vim-oscyank`'s autocmd was moved out of `autocmds.lua` into `editing.lua` colocated with its plugin spec (Task 1.7.5a); and the Migration Plan/Risk Control coc.nvim narrative fix (architecture-review.md's concern #2) is the same fix that resolves this review's original BLOCKER.

Several concerns should be addressed before/during implementation — none require replanning, all are scoped fixes to specific tasks. + +## Blockers +(none) + +## Concerns + +- [ ] **Task 2.3.1a (DAP keymaps via lazy `keys`) vs. Story 1.3.1 (safe-map registry)** — Story 1.3.1's acceptance criteria claims "all real keymaps across the whole config use `map()`" and the Pattern Decisions table states the safe-map registry makes "zero duplicate binds" a *self-enforcing startup invariant, not a hope*. But Task 2.3.1a explicitly wires DAP keymaps (`db`, `dc`, `di`, `do`, `dO`, `dr`, `du`) via lazy.nvim's own `keys = {...}` spec field (necessary to solve pitfalls.md §2's "breakpoint doesn't bind if dap isn't force-loaded first" problem) — a mechanism that calls `vim.keymap.set` internally, bypassing `require("tstapler.util").map()` entirely. This means the duplicate-detection registry has an unacknowledged blind spot for exactly the class of keymaps (lazy-loaded plugin `keys` triggers) the plan's DAP epic requires. The invariant Story 1.3.1 establishes is therefore incomplete, not global, contradicting its own acceptance criteria. + - **Remediation**: before implementing Task 2.3.1a, extend `lua/tstapler/util.lua` with a `reserve(mode, lhs)` (or `map_lazy_keys(specs)`) helper that registers each lazy `keys` entry's `(mode, lhs)` in the same collision table `map()` uses, then returns a lazy.nvim-compatible `keys` array — so DAP's force-load keymaps are still caught by the duplicate-bind invariant. Apply the same helper wherever any other plugin spec (e.g. gitsigns, oil.nvim, fzf-lua if any of them use `keys=` instead of `on_attach`/inline `map()`) sets keys through lazy.nvim's own mechanism rather than through `map()` directly. + +- [ ] **Migration Plan / Risk Control narrative vs. Task 2.1.1c** — The Migration Plan's Risk Control section states: "coc.nvim is removed atomically in Phase 2 ... each language is fully cut over (coc extension + coc keymaps removed in the same change the native server is added) before the next begins." But Task 2.1.1c removes coc.nvim, ale, and all coc-only source plugins from the tree *entirely* during Phase 2/Epic 2.1 — before Rust (Phase 3), Python (Phase 4), or TS/JS (Phase 5) get their native LSP servers. There is no "coc extension" left to remove in Phases 3–5 because coc.nvim is already gone; Stories 3.1.1/4.1.1/5.1.1 correctly contain no coc-removal step. The Risk Control text's framing ("each language is fully cut over ... before the next begins") describes a per-language incremental coc-teardown pattern that only actually happens once (for Go); it doesn't recur for the other three languages and shouldn't be described as if it does. This is a documentation-consistency defect, not a functional one — the actual task ordering is safe (coc.nvim is dead well before any later phase's native server is enabled, so no coexistence ever occurs) — but it could mislead an implementer into looking for a "remove coc extension for Rust" step that doesn't exist and was never planned. + - **Remediation**: reword the Risk Control bullet to state plainly that coc.nvim (all languages) is removed once, atomically, at the end of Epic 2.1/Task 2.1.1c — not per-language — and that Phases 3–5 are pure additions of native LSP/DAP for languages that already lost coc support in Phase 2. Optionally add a one-line note to the Migration Plan clarifying that Tyler should keep using master's plain `nvim` (coc-intact) for Rust/Python/TS-JS work during Phases 3–5, since the worktree's `nvim-next` config has zero LSP for those languages until their phase lands — this is implied by the NVIM_APPNAME isolation design but never stated explicitly. + +- [ ] **Duplicated leader-group source of truth (keymaps.lua comment vs. which-key.lua registration)** — Task 1.3.2a documents the leader-group scheme (`f`ind/`c`ode/`d`ebug/`g`it/`h`unk) as "the single source of truth" via a header *comment* in `keymaps.lua`. Task 1.4.1a then independently re-declares the same group labels as an executable which-key registration table in `plugins/which-key.lua`. Nothing links these two beyond both authors remembering to update the comment and the table in lockstep — a comment cannot function as a real single source of truth for a runtime-registered value. This is the same class of duplication problem (primitive obsession / no single source of truth) the plan's own module-layout rationale is designed to eliminate elsewhere. + - **Remediation**: define the leader-group table once — e.g. `lua/tstapler/leader_groups.lua` returning `{ f = "find", c = "code", d = "debug", g = "git", h = "hunk" }` — and have both `keymaps.lua`'s header comment (generate it, or just reference the module) and `which-key.lua`'s registration `require("tstapler.leader_groups")` consume the same table, so adding/renaming a group is a one-file change. + +- [ ] **`vim-oscyank`'s config split across `autocmds.lua` (Phase 1/Epic 1.2) and `editing.lua` (Phase 1/Epic 1.7)** — Task 1.2.2a ports the `vim-oscyank` `TextYankPost` autocmd into `autocmds.lua`, a general non-plugin file, while the plugin's own lazy.nvim spec isn't declared until Task 1.7.5a in `editing.lua`, five epics later. This recreates, in miniature, the exact "declaration and config live hundreds of lines apart" defect (architecture.md §1) that motivated the whole module-per-concern layout — oscyank's plugin declaration and its behavior-defining autocmd now live in two different files instead of one. It's also a minor construction-order oddity: for the span between Task 1.2.2a and Task 1.7.5a, `autocmds.lua` references a plugin (`vim-oscyank`) that doesn't exist yet in the tree (low risk since it's config-time, not a runtime dependency, but still avoidable). + - **Remediation**: move the `vim-oscyank` `TextYankPost` autocmd out of `autocmds.lua` and into `editing.lua`, colocated with its plugin spec in Task 1.7.5a (either inline in the spec's `config`/`init` function or immediately adjacent to it). Keep only the non-plugin `YankBufferFilename()` function (if it has no plugin dependency) in `autocmds.lua`. + +## Nitpicks +- Epic 6.1 (neogit + diffview) is gated on "if fugitive+gitsigns proved insufficient after Phases 2-5" with no concrete threshold for what "insufficient" means — unlike every other story's mechanical, checkhealth/verbose-map-based acceptance criteria. Consider adding one concrete trigger condition (e.g. "N times per week reaching for a merge-conflict UI fugitive doesn't have") so this doesn't become an indefinitely-deferred, unverifiable judgment call. +- Build-vs-buy.md's Option 4 recommendation to adapt kickstart.nvim's `debug.lua` for DAP wiring is only referenced at the Pattern Decisions table level ("Base skeleton" row); the actual DAP tasks (2.3.1a, 3.1.1a, 4.1.1b) don't call it out as a reference source at the point where it matters most (DAP being the highest-risk area per requirements.md's own Rabbit Holes). Consider adding an explicit "adapt from kickstart's debug.lua / LazyVim's dap.core extra" note directly to Task 2.3.1a. +- Task 1.1.1a ports the lazy.nvim bootstrap from the existing `.vimrc.dein` (Tyler's own prior code) rather than diffing against kickstart.nvim's current canonical bootstrap snippet, a mild divergence from build-vs-buy.md's "use kickstart.nvim as the literal starting point" recommendation. Low risk — lazy.nvim bootstrap snippets are nearly identical everywhere — but worth a one-line check against kickstart's current `init.lua` before treating the ported block as final. +- No task performs a systematic sweep of every lazy-loaded plugin's trigger for the "installed but never actually loads" failure mode (pitfalls.md §5 / lazy.nvim#858, #1049) beyond the two cases the plan explicitly handles (vimwiki's `lazy = false`, DAP's force-load `keys`). Consider adding a generic line to the Observability Plan's smoke-test checklist: after running the full smoke test, run `:Lazy profile` and confirm every plugin shows a non-zero load count, to catch any other silently-dead lazy trigger the smoke test's happy-path clicks didn't happen to exercise. diff --git a/project_plans/neovim-hardening/implementation/plan.md b/project_plans/neovim-hardening/implementation/plan.md new file mode 100644 index 00000000..bebf1540 --- /dev/null +++ b/project_plans/neovim-hardening/implementation/plan.md @@ -0,0 +1,767 @@ +# Implementation Plan: neovim-hardening + +**Feature**: Full Lua rewrite of Tyler's decade-old vimscript+coc.nvim Neovim config into a modular `init.lua` + `lua/tstapler/` tree on native LSP + DAP + treesitter, pruning ~50 plugins to an audited minimal set, migrating language-by-language (Go pilot first), on Neovim 0.11.6. +**Date**: 2026-07-15 +**Status**: Ready for implementation +**System type**: Personal developer-tooling config migration — cross-cutting, Complexity 4, Large appetite (3–6 weeks) +**ADRs**: ADR-001 (stay on nvim 0.11.6 + treesitter `master`), ADR-002 (drop vim support, full Lua rewrite), ADR-003 (lualine statusline), ADR-004 (oil.nvim explorer) + +--- + +## Step 0.5 — Creative pass: sequencing/rollout strategy (chosen + rejected) + +Three high-level rollout strategies were considered (stack choices are already fixed by research; this is purely about ordering): + +- **(a) Infrastructure-first** — get lazy.nvim, options, keymaps, statusline, explorer, fzf-lua, gitsigns, treesitter fully solid before touching any LSP. *Strength*: clean, stable foundation. *Weakness*: defers the load-bearing, highest-risk work (coc→native-LSP, DAP) to the very end — you don't learn whether the risky part works until weeks in. +- **(b) Pilot-language-first** — prove the full LSP+DAP+nav+git vertical on Go end-to-end before building shared infra. *Strength*: retires the biggest risk first. *Weakness*: builds LSP/DAP keymaps and treesitter before the shared keymap module and safe-map registry exist, guaranteeing rework of the keymap layer. +- **(c) Parallel-track** — interleave infra and pilot LSP work. *Weakness*: worst fit for a solo, evenings/weekends effort — context-switching cost and harder failure isolation. + +**CHOSEN — Hybrid "thin-infra-then-pilot vertical"**: build only the shared foundation the pilot actually depends on (plugin manager, options, the keymap module + safe-map registry, treesitter, statusline, explorer, fzf-lua, gitsigns, and all the deletions/cutover isolation) in Phase 1, then immediately prove the *entire* LSP+DAP+nav+git vertical on Go end-to-end in Phase 2 before replicating it for Rust/Python/TS-JS.

Live daily-driver; master stays usable until cutover.)* + +- **Development isolation (resolves the pitfalls.md §7 NVIM_APPNAME gap)**: Do NOT re-point `~/.config/nvim` at the worktree during development. Instead symlink `~/.config/nvim-next -> /.config/nvim` (one symlink, bypassing cfgcaddy) and always launch the new config as `NVIM_APPNAME=nvim-next nvim`. This isolates `~/.config/nvim-next`, `~/.local/share/nvim-next`, `~/.local/state/nvim-next`, `~/.cache/nvim-next` from the live `~/.config/nvim` + `~/.local/share/nvim` (coc/master) — so a broken Mason binary or half-updated plugin during testing cannot contaminate master's runtime state, and a mid-week emergency `nvim` still gets master's known-good setup. Add a shell alias `nvn='NVIM_APPNAME=nvim-next nvim'` for the dev loop (in a local, un-synced shell file, not committed). +- **Reversibility**: master branch is untouched throughout; the live `~/.config/nvim/init.vim -> .vimrc` symlink and coc setup keep working. Rollback at any pre-cutover point = keep using plain `nvim` (master) and delete the `~/.config/nvim-next` symlink. `lazy-lock.json` is committed so plugin versions validated in the worktree are exactly what cutover deploys. +- **Cutover strategy**: (1) Build entirely in the worktree under `NVIM_APPNAME=nvim-next`. (2) Progressively dogfood: once a language's phase smoke test passes **against one of Tyler's actual real projects for that language, not a toy example** (2.3.2 Go, 3.1.1b Rust, 4.1.1c Python, 5.1.1b TS/JS) and its coc-teardown task lands immediately after (2.3.3a Go, 3.1.1c Rust, 4.1.1d Python, 5.1.1c TS/JS), shift that language's real daily-driver work to `nvn` (see Risk Control's "Master stays the daily driver..." bullet) — until then, that language's real work stays on plain `nvim`/master. Once all four languages have shifted, dogfood a full week per the success metric using `nvn` for real daily work across all four languages. (3) Only when stable, merge `dotfiles-harden-neovim` → `master`. (4) The merge deletes the two `.vimrc → init.vim` cfgcaddy rename entries and the `coc-settings.json` link, and adds nothing (the `.config/nvim/` tree default-mirrors). (5) Run cfgcaddy install: `~/.config/nvim/init.vim` symlink disappears, `~/.config/nvim/init.lua` + `lua/**` + `lazy-lock.json` appear. (6) First plain `nvim` launch installs plugins/Mason tools from the committed lockfile. +- **Rollback procedure (mid-migration, per-language)**: if a language's real-project smoke test fails, or its native LSP/DAP breaks on real work *after* Tyler has already shifted that language's daily-driver use to `nvn`, rollback is per-language, not repo-wide: switch that language's daily-driver work back to plain `nvim`/master immediately. coc.nvim's extension for that language is still installed and functional on master — its teardown task (e.g. Task 2.3.3a for Go) only ever edits the `nvn` worktree's `autocmds.lua`/`g:coc_global_extensions`, never master's — so master's fallback needs zero repair and no `git revert` is needed. Any other language that has already progressively cut over keeps using `nvn` unaffected; only the broken language's daily use reverts, while the worktree keeps evolving to fix it and re-attempts its own cutover once fixed. +- **Rollback procedure (post-cutover)**: `git checkout master~1` (or revert the merge) in `~/dotfiles`, re-run cfgcaddy install to restore the `init.vim` symlink, relaunch `nvim`. The old coc config is fully intact because master before the merge was never modified. Because dev used a separate `NVIM_APPNAME`, master's `~/.local/share/nvim` (coc/lazy state) was never touched by testing, so rollback is genuinely clean — not just at the config-source level. + +## Observability Plan +*(Not a service. Substitutes per requirements.md.)* +- **Accessibility statement**: Keyboard-only operation is preserved by construction — no plugin choice in this plan (oil.nvim, fzf-lua, which-key.nvim, tiny-code-action.nvim, gitsigns, nvim-dap-ui) introduces a mouse-only interaction; every action has a keyboard binding. Diagnostics and status signs use color AND text/icon, never color alone: native `vim.diagnostic` signs (Task 2.1.1a) render distinct glyphs per severity, not just a colored sign-column highlight, and lualine's diagnostics segment (Task 1.7.1a) renders severity counts as icon+number, not a bare color chip. This turns an otherwise-implicit property into a documented, deliberate check rather than an assumption. +- **Startup benchmark**: Capture baseline BEFORE any change: `nvim --startuptime /tmp/nvim-baseline.log` on master's config, 3 runs, record the final "NVIM STARTED" total. After each phase, `NVIM_APPNAME=nvim-next nvim --startuptime /tmp/nvim-next.log`, 3 runs. Also keep `dstein64/vim-startuptime` (`:StartupTime`) in the new config. Gate: new-config median total must be ≤ baseline median (Success Metric). If a phase regresses it, the regression is almost always over-eager `lazy = false`/`VeryLazy` left in from debugging (pitfalls.md §5) — convert to a proper `ft`/`cmd`/`keys` trigger before proceeding. +- **Smoke-test checklist** (run under `nvn` before calling any language story done — the per-language criteria appear in each Story's acceptance section). **Before that language's coc-teardown task specifically, this checklist must run against an existing real project Tyler actively works in for that language, not a toy/example repo** (Go: Story 2.3.2; Rust: Task 3.1.1b; Python: Task 4.1.1c; TS/JS: Task 5.1.1b) — pre-mortem.md P1 #3: a setup that only works on a toy repo but breaks on the real thing after the coc fallback is gone leaves no recovery path: + - **LSP**: open a real file of the language → `:checkhealth vim.lsp` shows exactly ONE client attached for the buffer; `gd` jumps to definition; `grr` lists references; `grn` renames across files; `K` shows hover. + - **DAP**: set a breakpoint, launch debug, confirm it stops, inspect a variable in dap-ui, step over, continue to exit. + - **Fuzzy-find**: `ff` opens files with live preview; `fg` live-greps. + - **Git**: edit a tracked file → gitsigns shows the hunk in the sign column; `hs` stages it; `:Git` (fugitive) opens status. + - **No-duplicate-keymap**: config loads with zero errors (safe-map registry throws on any duplicate `(mode,lhs)` — see Story 1.3.1). + +## Risk Control +- **Feature flag**: not gated — feature-branch worktree (`dotfiles-harden-neovim`) instead, per requirements.md Risk Control. No parallel-config env switching beyond the dev-only `NVIM_APPNAME=nvim-next` isolation. +- **NVIM_APPNAME isolation**: the `nvim-next` app-name (Migration Plan above) is the concrete mechanism making "the worktree isolates risk" true at the runtime-state level (shared `~/.local/share/nvim`, Mason binaries, lazy checkouts), not just the config-source level — closing the pitfalls.md §7 gap. +- **Rollback procedure**: pre-cutover — use plain `nvim` (master), delete `~/.config/nvim-next`. Mid-migration, per-language — see Migration Plan's "Rollback procedure (mid-migration, per-language)" bullet: switch just that language's daily use back to master; no repo-level action needed. Post-cutover — revert the merge in `~/dotfiles` + re-run cfgcaddy. Maintain a `REMOVED-PLUGINS.md` scratch list (dev-only, not committed) of every pruned plugin so a surfaced workflow gap can be re-added from a known list rather than rediscovered (pitfalls.md §4). +- **Staged rollout as staging**: the per-language sequence (Go pilot → Rust → Python → TS/JS) IS the staging strategy, and it applies to coc.nvim's teardown too — not just the native-LSP rollout. Each language's coc extension + `b:coc_enabled` disable is torn down only after that language's native LSP/DAP stack is proven **against a real project Tyler actively works in** (Task 2.3.3a for Go, 3.1.1c for Rust, 4.1.1d for Python, 5.1.1c for TS/JS — which also removes the `coc.nvim` plugin spec itself, since TS/JS is the last language). coc.nvim and a native client are never dual-run *persistently* for the SAME filetype (architecture.md §6/§4A) — the brief overlap between a language's real-project smoke test and its teardown task (both back-to-back within the same phase) is a deliberate, minimal-duration exception, not a standing violation; coc.nvim legitimately keeps serving every not-yet-migrated filetype throughout Phases 2-4. That is a required, deliberate state, not an oversight (pitfalls.md §1: migrate one language at a time, fully; never a global flip). +- **Master stays the daily driver for not-yet-migrated languages**: during Phases 2-5, Tyler's real daily-driver work for a language that hasn't reached its phase's coc-teardown task yet continues under plain `nvim` (master, coc.nvim fully intact for that language) — `nvn` is dev/test-only for that language until its phase's real-project smoke test and coc-teardown task both land, at which point daily use for that language shifts to `nvn` **immediately**, not waiting on the other languages. This was implicit in the NVIM_APPNAME isolation design; it is now an explicit rule, not an assumption a future reader has to infer. +- **Progressive cutover banks partial progress (go/no-go safety net)**: because each language's daily-driver shift happens the moment its own teardown lands, a stall or burnout after Phase 2 does not waste the work already done — Go's LSP/DAP win is already in real daily use and stays that way indefinitely, with zero dependency on Rust/Python/TS/JS ever landing. Story 2.3.2/2.3.3 (Go) is the de facto go/no-go checkpoint for the rest of the project: if it passes, the pattern is proven and worth replicating; if the project stops there, nothing already shipped needs to be reverted (pre-mortem.md P1 #1). +- **Cutover muscle-memory friction (acknowledged, mitigated lightly)**: during the multi-week progressive per-language cutover, Tyler alternates between master's old flat/ad-hoc leader keys and `nvn`'s new grouped scheme depending on which language he's touching that day — a real, if minor, daily friction cost the Migration Plan should name rather than leave implicit. Mitigation: keep a printed/pinned one-page keymap cheat-sheet, generated from `lua/tstapler/leader_groups.lua` (the single source of truth already established, Task 1.3.2b), covering the new grouped scheme, visible during the transition weeks (Task 1.3.2c). This is a small, one-time generation step, not a new feature. + +## Unresolved Questions +- [ ] Does cfgcaddy symlink `.config/nvim` as one directory unit or file-by-file?

because the cutover strategy (Epic 7.4) gates the single merge on **all four** languages plus a full dogfood week, an unfinished migration either never merges (work permanently wasted) or gets force-merged under time pressure, leaving a coc+native hybrid frozen forever on master. | Weeks pass with no commits to the worktree after a phase lands; the per-language dogfooding shift (Migration Plan step 2) stalls at whichever language finished last and never advances further. | Restructure the cutover strategy to allow incremental per-language merges to master instead of one all-or-nothing merge: each phase's coc-teardown for that language is already a self-contained, verified state, so merge as soon as that language's smoke test + a dogfood period pass, rather than waiting on TS/JS too. Add an explicit go/no-go checkpoint after Phase 2 (Go). | P1 | +| 2 | The "startup time does not regress" Success Metric is mechanically re-verified only once, right after the Go pilot (Task 2.3.2a). Phases 3-6 add rustaceanvim, basedpyright+ruff+debugpy, vtsls, neogit+diffview, which-key, etc. with zero further `--startuptime` checks, and even the final merge task (7.4.1b) never re-runs the benchmark — the metric can regress by cutover with nobody having measured it. | nvim feels sluggish some time after cutover; by the time it's noticed, 4+ phases of plugin additions have landed since the last measurement, making the regression hard to bisect. | Add an explicit `--startuptime`-vs-baseline comparison to every phase's smoke-test task (3.1.1b, 4.1.1c, 5.1.1b, 6.1.1a) and to the real merge gate (Task 7.4.1b) — make passing it a literal condition of Story 7.4.1's acceptance criteria, not just Task 2.3.2a's. | P2 | +| 3 | gopls/delve and basedpyright/debugpy are smoke-tested against a single simple project per language; Tyler's real daily-driver repos include layouts the smoke tests never exercise (a Go `go.work` multi-module workspace; a Python project managed by asdf/direnv rather than the poetry/pipenv paths `resolve_python()` explicitly handles). The adapter that "works" in Phase 2/4 testing then fails to attach, resolve the interpreter, or hit a breakpoint the first time Tyler debugs a real project — *after* that language's coc fallback has already been torn down, forcing exactly the "switch to IntelliJ" habit the project exists to remove. | After Go's coc-teardown (Task 2.1.1c) is merged/dogfooded, opening a real multi-module Go workspace shows wrong-root gopls behavior, or a debug session that never stops at a breakpoint, with no coc fallback left for that language. | Add a smoke-test task per language that runs the full LSP+DAP checklist against one of Tyler's actual complex real-world repos (not a toy/single-module repro) — specifically covering `go.work` for Go and asdf/direnv for Python — as a precondition for that language's coc-teardown task (2.1.1c/4.1.1d), not just a nice-to-have. | P1 | +| 4 | NVIM_APPNAME isolation only scopes nvim's own config/data/state/cache directories (Migration Plan's isolation claim). It does not scope shared, machine-global tool state — most concretely, `rustup component add rust-analyzer` (deliberately NOT mason-managed, per pitfalls.md §2) mutates the single shared rustup toolchain that master's still-live coc-rust-analyzer may also depend on if it references a system/PATH rust-analyzer rather than a bundled copy. A "isolated" dev-loop action in the worktree can silently change Rust support on master before Rust's own phase (3) ever lands. | master's coc.nvim-driven Rust diagnostics/completion change behavior, or a version-mismatch error appears, during Phase 3 dev work — even though Tyler never touched the master nvim config directly. | Before running any `rustup component add/update` (or other shared-toolchain-manager command) during Phase 3 dev, check what binary master's live coc-rust-analyzer is actually configured to use; if it's a system/PATH binary, snapshot/pin the toolchain state first and treat any mutation as an explicit, logged action rather than an implicitly "isolated" one. | P2 | +| 5 | `~/personal-wiki` is used far less than code editing, so a regression introduced anywhere in Phases 1-6 (a global keymap shadowing one of vimwiki's own ftplugin-internal binds — outside the safe-map registry's coverage, since vimwiki sets those itself, not via `map()`/`reserve()` — or a treesitter/filetype-detection ordering change) goes unexercised until Story 7.2.1 in Phase 7. Even 7.2.1's acceptance criteria only check filetype/parser/wikilink-follow, not the fuller vim-zettel/table-mode/`:VimwikiIndex` surface, so a narrower regression can reach the mandatory post-cutover dogfood week undetected. Worse: reverting the whole branch after weeks of enjoyed Go/Rust/Python/TS gains is a costly trade Tyler would be reluctant to make just to fix a low-frequency wiki issue — so he's more likely to silently work around a broken wiki than actually revert, meaning the "full week without reverting" metric can pass while the wiki is quietly broken. | Days into the post-cutover dogfood week, opening a real wiki page for the first time surfaces a broken link-follow, missing table formatting, or a vim-zettel command error nothing in Phases 1-6 exercised. | Broaden Story 7.2.1's acceptance criteria to exercise vim-zettel commands and vimwiki table-mode, not just filetype/parser/wikilink-follow. Additionally schedule at least one explicit wiki-editing session during Phases 1-6 dev (not deferred entirely to Phase 7) so a regression surfaces while it's still cheap to trace to its introducing phase. | P2 | + +## P1 Items (address before implementation) +- [x] #1 — Resolved 2026-07-15: requirements.md's Risk Control revised (per user decision) to progressive per-language cutover — each language's real daily-driver use shifts to `nvn` as soon as its own smoke test passes, banking that language's progress independent of the others. plan.md's Migration Plan/Risk Control/Story 7.4.1 updated to match; Go's win is banked at Task 2.3.3a regardless of Rust/Python/TS-JS timing. User explicitly confirmed this substitute mechanism via AskUserQuestion, 2026-07-15, choosing progressive dogfooding over strict single-swap. +- [x] #3 — Resolved 2026-07-15: plan.md restructured so each language's coc-teardown task (Go: 2.3.3a; Rust: 3.1.1c; Python: 4.1.1d; TS/JS: 5.1.1c) is now gated on a real-project smoke test (Story 2.3.2 for Go against a real/`go.work` repo; equivalent real-project requirements added to 3.1.1b/4.1.1c/5.1.1b for Cargo workspace / asdf-direnv Python / real monorepo) — coc fallback is never removed before the native replacement is proven on Tyler's

This is an open decision, not pre-decided. +- Auditing and pruning the full existing plugin list (~50 plugins across `.vimrc.dein`) for redundancy and staleness. +- Deleting or explicitly re-integrating the three orphaned/unsourced files (`.vimrc.local`, `.vimrc.bundles.local`, `.vimrc.plug`). +- Code intelligence & refactoring: reliable LSP-backed go-to-definition, find references, rename, and safe refactors for Go, Rust, Python, TypeScript/JavaScript. +- Debugging: DAP-based breakpoint/step-through debugging, prioritized for Go and Python. +- Project/file navigation & fuzzy search: consolidate to one fuzzy-finder covering files, buffers, symbols, and live grep. +- Git integration: consolidated git status/diff/blame/merge-conflict UI (audit vim-fugitive/Merginal/vimagit overlap). +- Minor cleanup pass on `.ideavimrc` if there's easy shared value (e.g. consistent keybindings with the new Neovim config) — small effort, not a redesign of the IntelliJ/IdeaVim setup. +- Updating `.cfgcaddy.yml` link mappings if the config file layout changes (e.g. splitting into `init.lua` + `lua/` modules). + +### Out of Scope +- Redesigning or expanding the IntelliJ/IdeaVim setup beyond a minor `.ideavimrc` cleanup pass. +- Non-daily-driver languages/tooling not called out above (Java, Ruby, Dart, Elixir, etc. currently referenced in coc extensions/plugins) — audit for removal if unused, but no new investment in them. +- Windows support (`.cfgcaddy.yml` has a Windows nvim mapping) — out of scope unless it falls out naturally from the Linux/macOS work. +- Zettelkasten/wiki plugins (vimwiki, vim-zettel) and distraction-free writing plugins (goyo, limelight, zenroom2) — orthogonal to the "IDE-like" goal; only touch if clearly dead weight, not to improve. + +## Rabbit Holes +- **vimscript-vs-Lua decision**: could balloon if not timeboxed — research phase should produce a clear recommendation with a decision criteria (migration effort vs. capability gap), not an open-ended exploration. +- **DAP adapter setup per language** is often the most fragile part of a "modern" Neovim config (adapter installation, path discovery, per-project launch configs) — budget real time here, don't assume it's a quick plugin install. +- **coc.nvim → native LSP migration** (if the Lua rewrite is chosen) touches snippets, completion, formatting, and diagnostics simultaneously — these are easy to half-migrate and end up with a worse hybrid than the original. +- **Fuzzy-finder consolidation** touches muscle-memory keybindings across ctrlp/ctrlspace/fzf — likely to cause friction regardless of which one wins; plan for a keybinding-compat pass. +- **vim-zettel / vimwiki** integration with the personal wiki (`~/personal-wiki/logseq/pages`) is a live dependency for note-taking — do not break it while pruning, even though it's out of scope for improvement. + +## Alternatives Considered +- Keep vimscript config as-is, only delete the 3 dead files and dedupe fuzzy-finders/git plugins — rejected as insufficient on its own; deferred to research as one candidate outcome of the vimscript-vs-Lua analysis rather than ruled out. +- Full switch to a pre-built Neovim distribution (LazyVim, NvChad, AstroNvim) — worth evaluating in research as a build-vs-adopt option, but Tyler's config has enough personal customization (zettel workflow, custom filetype settings, personal snippets) that full adoption may not fit; research should weigh this explicitly. + +## Feasibility Risks +- DAP adapter availability/quality varies significantly by language (Go's delve integration is generally solid; verify Python's debugpy and Rust's codelldb/lldb-vscode maturity before committing). +- coc.nvim and native LSP client cannot cleanly run side-by-side for the same language servers — the vimscript-vs-Lua decision is effectively load-bearing for the whole plan, not a cosmetic choice. +- Personal wiki workflow (vimwiki/vim-zettel) depends on plugins that may not have modern Lua equivalents with feature parity. +- No existing test/CI coverage for dotfiles config correctness beyond `install.sh`/shellcheck — validation will rely on manual smoke-testing per language, not automated tests. + +## Observability Requirements +Not a service — no metrics/alerts pipeline. Substitute: startup time benchmark (before/after, via `vim-startuptime`) captured in the plan, plus a manual smoke-test checklist (LSP attach, DAP breakpoint hit, fuzzy-find, git status) run per daily-driver language before merging to master. + +## Risk Control +Build the new config within this feature-branch worktree (`dotfiles-harden-neovim`), isolated via `NVIM_APPNAME=nvim-next` so its plugin/Mason state never touches master's `~/.config/nvim`/`~/.local/share/nvim`. The current coc.nvim-based config on `master` stays the daily driver for any language not yet migrated. + +*(Revised during Phase 4 validation — see `implementation/pre-mortem.md` and `implementation/adversarial-review.md`.)* Rather than a single big-bang swap, cutover happens **progressively per language**: once a language's native LSP/DAP setup passes its Phase smoke test (via `nvn`), that language's *real* daily-driver work shifts to `nvn` immediately — it does not wait for the other languages to finish. This deliberately trades "two live configs coexisting for several weeks" for avoiding two bigger risks the all-or-nothing approach carried: (1) a mid-migration burnout or stall permanently freezing a half-finished coc+native hybrid with no clean revert, and (2) discovering a DAP/LSP problem on a real project only after that language's coc.nvim fallback has already been torn down. The final merge to `master` happens once all in-scope languages have been progressively cut over and the full config has survived one week of combined daily-driver use. Rollback at any point is per-language: switch that language's daily work back to plain `nvim`/master (coc.nvim stays installed and functional there until its own teardown task runs) — no repo-level revert needed mid-migration. Full rollback of the whole effort, if ever needed, is `git checkout master` (or simply not merging the branch). + +## Open Questions +- Does the vimscript-vs-Lua research land on a clean recommendation, or is it close enough to need a spike/prototype before deciding? (Research phase should flag this rather than force a premature decision.) +- Which specific DAP adapters are mature enough today for Go/Python/Rust/TS-JS?

Safe to delete outright. +- `.ideavimrc` is 2 lines: `set surround` / `set commentary`. Trivial; not a redesign target. +- **cfgcaddy semantics** (confirmed via the tool's own README, `tstapler/cfgcaddy`): by default, + cfgcaddy mirrors every file in the dotfiles repo to the same relative path under + `linker_dest` ($HOME) *unless* it matches an `ignore:` glob. The explicit `links:` block in + `.cfgcaddy.yml` is only needed for **exceptions** — renames, multi-destination fan-out, or + OS-conditional paths. This resolves an apparent discrepancy: `.vimrc` has no explicit + `links:` entry pointing at `~/.vimrc` — it doesn't need one, because default mirroring + already produces `~/.vimrc`. The *explicit* entries are the two extra renames: + `.vimrc → .config/nvim/init.vim` (Linux/Darwin) and the Windows equivalent. So the "shared + vimscript file" constraint in requirements.md is real and currently active, not vestigial. +- Directory-as-one-unit linking already has precedent in this exact `.cfgcaddy.yml`: + `.config/nixpkgs`, `.mixxx/controllers`, `.claude/skills`, `.claude/agents`, `.claude/commands` + are all linked as bare directory `src:` entries (or via default mirroring), not enumerated + file-by-file. Splitting nvim config into a `lua/` tree is not a new pattern for this tool. +- Side-finding: `.cfgcaddy.yml`'s `.vimsnippets` multi-dest entry links to + `.vim/bundle/.dein/stapler-snips` — an actual dein.vim path, distinct from the + lazy.nvim-via-`.vimrc.dein` setup that's actually in use. This is itself a small piece of + migration debt (a previous dein→lazy.nvim migration that didn't clean up cfgcaddy). Worth + pruning in the same pass as the three dead vimscript files, once confirmed nothing still + reads that path. + +## 1. File/module layout pattern + +**Community standard for 2025-2026** (kickstart.nvim, LazyVim, and the broad devlog/blog +consensus converge on this): `init.lua` as a thin bootstrap, plus a `lua//` tree: + +``` +.config/nvim/ + init.lua -- lazy.nvim bootstrap + require("tstapler") + lua/tstapler/ + init.lua -- requires options/keymaps/autocmds, then lazy.setup(...) + options.lua -- vim.opt.* (ports .vimrc's Options block) + keymaps.lua -- non-plugin-specific vim.keymap.set (ports .vimrc's Mappings block) + autocmds.lua -- filetype settings (ports .vimrc's ~20 au FileType blocks) + plugins/ + lsp.lua -- nvim-lspconfig + mason + mason-lspconfig + dap.lua -- nvim-dap + nvim-dap-go/python + dap-ui + mason-nvim-dap + completion.lua -- nvim-cmp/blink.cmp + snippet engine + treesitter.lua + finder.lua -- the single consolidated fuzzy-finder (telescope or fzf-lua) + git.lua -- the single consolidated git UI + wiki.lua -- vimwiki + vim-zettel (vimscript plugins, config via vim.g) + ui.lua -- statusline, colorscheme + editing.lua -- surround, comment, autopairs, etc. +``` + +`lazy.setup({ { import = "tstapler.plugins" }, ... })` auto-loads every file under +`plugins/` — adding a new plugin file requires zero edits to `init.lua`. + +**Why this matters at ~25-30-plugin scale (post-pruning)**: the current `.vimrc.dein` +already exhibits the failure mode a single-file Lua config would just re-encode in a new +syntax — plugin *declaration* and plugin *configuration* live hundreds of lines apart. A +module-per-concern layout fixes this by construction: a plugin's `lazy.nvim` spec table and +its `opts`/`config` function live in the same file, often the same table. Swapping coc.nvim +for native LSP becomes "delete/rewrite `plugins/lsp.lua`," not a scroll-and-grep exercise +across a 565-line file. This is the single biggest maintainability lever available in this +migration, independent of the vimscript-vs-Lua decision (see §3) — even a vimscript-retained +option benefits from *some* form of this separation, though vimscript lacks `require()` and +can't get it as cleanly. + +Do **not** go granular to one-file-per-plugin (50+ tiny files) — group by functional concern +instead. One-per-plugin adds navigation overhead without a corresponding benefit once plugins +are already grouped by concern; reserve per-file granularity for plugins complex enough to +need it on their own (LSP and DAP will likely want to stay split further internally, e.g. +`lsp/servers.lua`, `dap/go.lua`, `dap/python.lua`, if they grow to warrant it — cross that +bridge only if `plugins/lsp.lua` or `plugins/dap.lua` actually gets unwieldy). + +## 2. cfgcaddy integration + +**Recommendation: link `.config/nvim` as one directory unit, relying on cfgcaddy's default +mirror behavior — add no new explicit `links:` entry.** None of `.config/nvim/init.lua` or +`.config/nvim/lua/**` match any existing `ignore:` pattern (no `*.lua` exclusion exists), so +default mirroring already produces the correct `~/.config/nvim/init.lua` and +`~/.config/nvim/lua/tstapler/*.lua` paths with zero new config. This is not a novel ask of the +tool — it already treats `.config/nixpkgs`, `.claude/skills`, `.claude/agents`, etc. as +directory-level units in this same `.cfgcaddy.yml`. + +**Required cfgcaddy changes** (this part is not optional, it's a conflict-avoidance fix): +delete the two existing explicit rename entries that point `.vimrc` at nvim's init path — +```yaml + - src: .vimrc + dest: .config/nvim/init.vim + os: "Linux Darwin" + ... + - src: .vimrc + dest: "%userprofile%\\AppData\\Local\\nvim\\init.vim" + os: "Windows" +``` +Once the new tree provides its own `init.lua`, leaving these in place would create a stale +`~/.config/nvim/init.vim` symlink to `.vimrc` sitting *alongside* the new `init.lua` — +Neovim's own startup rule is that if both `init.vim` and `init.lua` exist in the config +directory it treats this as an error condition (or at best undefined precedence depending on +version). This must be removed in the same change that adds the new tree, not as a followup. + +Splitting into multiple Lua files does **not** complicate cfgcaddy's per-file link model, +because cfgcaddy's model is already directory-capable, not strictly per-file — the model this +migration should worry about is the opposite: whether cfgcaddy's directory linking makes ONE +symlink for the whole directory (new files added later "just work" without rerunning the +installer) or walks the tree at install-time and links each file individually (new files +require rerunning `bootstrap-dotfiles.sh`/cfgcaddy before nvim can see them). The README +fetch did not settle this definitively. **Recommend a cheap empirical check before relying on +it**: touch a new file inside an existing directory-linked path already in +`.cfgcaddy.yml` (e.g. `.claude/skills/`) and check whether it appears under `~/.claude/skills/` +without rerunning cfgcaddy. If it's file-level (not whole-directory), add "rerun cfgcaddy +install" as an explicit step whenever a new `plugins/*.lua` file is added during this +migration — cheap to document, expensive to debug blind (a plugin file that silently isn't +even present on disk in `$HOME` looks identical to a lazy-loading bug, see §4). + +Keep the existing standalone `.config/nvim/coc-settings.json` link entry only for as long as +coc.nvim survives in any form (see §3); delete it in the same commit that removes coc.nvim +entirely. + +## 3. Migration strategy: vimscript vs. Lua — architectural options + +**Option A — Shared vimscript core + Lua-only IDE layer, `has('nvim')`-gated.** +Keep `.vimrc` mostly as-is (options/mappings/autocmds stay vimscript, still shared with plain +vim), keep the `lua << EOF ... EOF` heredoc bootstrap for lazy.nvim, swap coc.nvim+ale for +nvim-lspconfig+mason+nvim-dap *inside* the existing heredoc pattern, gated by `has('nvim')`. +- *Migration/integration complexity*: low for the file-layout question (no restructuring), but + this does **not** reduce the actual hardest work — the coc→native-LSP swap (requirements.md's + named rabbit hole) is exactly as large and exactly as risky whether it lives in a heredoc or + a `lua/` tree. It only avoids solving the maintainability problem in §1. +- *Risk*: heredoc-embedded Lua has no module system (no `require()`, no per-file lazy-loading + of your *own* config code), poor tooling support (a single giant `lua << EOF` block doesn't + get its own LSP/treesitter treatment as cleanly as real `.lua` files), and doesn't scale to + the amount of new LSP/DAP/treesitter config this migration adds. This option papers over the + current file's core defect rather than fixing it — it's the "band-aid," not a real option + for a migration explicitly scoped to be "large" (3-6 weeks). + +**Option B — Full Lua rewrite; vim gets a frozen legacy snapshot.** +Build the `lua/tstapler/` tree from scratch for Neovim only. Leave `.vimrc` exactly as it is +today (or trim only the neovim-specific stray comments), so plain `vim` keeps getting exactly +today's experience via cfgcaddy's default mirror to `~/.vimrc`, untouched by this migration. +Neovim stops reading `.vimrc` entirely — remove the two `.vimrc → init.vim` rename entries +from `.cfgcaddy.yml` (§2) and let `init.lua`/`lua/**` mirror independently. +- *Migration/integration complexity*: medium. Two config surfaces to reason about + permanently (vimscript for bare vim, Lua for neovim), but they're now fully decoupled — + changing one can never regress the other. Wiki plugins (vim-zettel/vimwiki, see §5) need to + be re-declared in the new Lua tree, but this is a mechanical, low-risk port (§5). +- *Risk*: low, by design — this is the risk-control option. `master` branch stays fully + functional the entire time (per requirements.md's Risk Control section), and if anything goes + wrong, "the old file still works for vim" is not even relevant to nvim's cutover risk since + they're already fully split. + +**Option C — Full Lua rewrite; drop vim support entirely.** +Same Lua tree as Option B, but delete `.vimrc` (or reduce it to a two-line "unsupported, see +nvim" stub) rather than freezing it. One canonical config, one language, forever. +- *Migration/integration complexity*: lowest long-term (no permanent dual-language + maintenance), but requires confirming plain `vim` (not `nvim`) is genuinely unused in + Tyler's daily workflow before deleting its config — this migration's own constraints assume + nvim 0.11.6 as the baseline runtime and never call out a plain-vim use case as a + requirement or success metric. +- *Risk*: low technically, but carries a small "did I just break something I forgot I use" + risk if plain `vim` turns out to be invoked anywhere (bare SSH sessions to boxes without + nvim, `sudoedit`, `git commit` if `$EDITOR`/`core.editor` resolves to `vim` rather than + `nvim` in some context, etc.). + +**Recommendation: Option C as the target, with an explicit, cheap pre-check before +committing to it — fall back to Option B if the check fails.** + +Decision criteria (not just preference): +1. **Usage check** — grep shell history / `git config --get core.editor` / + `echo $EDITOR $VISUAL` across the machines this repo is deployed to for evidence of bare + `vim` invocation in the last few months. If it's genuinely zero (most likely, given `nvim` + is the pinned baseline and there's no plain-vim item anywhere in requirements.md's scope), + take Option C — delete `.vimrc`'s vim-only branches and stop the dual-maintenance burden + for good. +2. **If bare vim shows up anywhere** (even as a rare SSH-without-nvim fallback), take Option B + instead — the cost of freezing today's `.vimrc` as a legacy file is near-zero (it's not + touched again), and it removes the small residual risk of Option C for a case that does + exist. +3. **Option A is never the right call for this migration** given the explicit "Large (3-6 + weeks)" appetite and the requirement that the research phase produce a *reasoned* + recommendation rather than defer the hard part — Option A defers exactly the part + requirements.md flags as the load-bearing risk (§6) without buying any real safety in + exchange. + +This recommendation should be validated/confirmed in Phase 3 (planning) with a two-minute +usage check rather than re-litigated as an open research question — the check is cheap and +turns a preference into a fact. + +## 4. Migration-specific failure modes + +**A. coc.nvim + native LSP both registered for the same filetype.** +*What breaks*: duplicate diagnostics (two sets of signs/virtualtext for the same line), +duplicate completion sources fighting over ``/``, and silently "wrong" `gd`/`gr` +behavior (see D). This is requirements.md's named Feasibility Risk, and it is concrete, not +theoretical (see §6 for why they can't coexist even in principle). +*Detection*: `:LspInfo` (or `:checkhealth vim.lsp`) shows a client attached for the buffer +**and** `:CocInfo` / `call coc#rpc#ready()` is true for the same buffer/filetype. +*Mitigation*: treat this as an atomic, per-filetype cutover, never a lingering hybrid — the +same commit that adds `gopls` to `mason-lspconfig`'s `ensure_installed` must also remove +`coc-go` from `g:coc_global_extensions` (or, if doing it all at once, remove `coc.nvim` +entirely from the plugin spec). Never leave both installed *and* enabled for the same +filetype past a single work session. + +**B. Lazy-loading misconfiguration — plugin silently never loads.** +*What breaks*: a feature is just... absent, with no error, because the `event`/`ft`/`cmd` +trigger in the lazy.nvim spec never fires for the way the plugin is actually used. +*Detection*: `:Lazy` UI shows the plugin's load state; `:Lazy profile` shows which load +events actually fired; a manual smoke-test checklist per plugin (open a file of the relevant +type, run one command the plugin provides, confirm it's not `E492: Not an editor command`) +run before considering a plugin "migrated." +*Mitigation*: for anything safety-critical during the transition (LSP, DAP, treesitter), +prefer broad triggers (`lazy = false`, `VeryLazy`, `BufReadPre`) over narrow, guessed +triggers, and only tighten to precise `ft`/`cmd`/`keys` triggers after the smoke test +confirms it works — optimize load time last, correctness first. + +**C. Treesitter parser/query version mismatches.** +*What breaks*: broken syntax highlighting/folding (folding matters here — `Konfekt/FastFold` +is already in the current plugin list) or fatal Lua errors on buffer open, when a parser +grammar's ABI drifts from what the installed `nvim-treesitter` revision or Neovim 0.11.6's +bundled treesitter runtime expects. +*Detection*: `:checkhealth nvim-treesitter`; error text mentioning parser/query +incompatibility on file open. +*Mitigation*: pin `nvim-treesitter` via lazy.nvim's lockfile (`lazy-lock.json`, committed to +the repo) rather than floating `main`; treat `:TSUpdate` as a deliberate, reviewed action tied +to a config change, not something that runs unattended. + +**D. Keymap collisions between old and new plugin sets during transition.** +*What breaks*: e.g. `vim-ctrlspace`'s `` fighting a new finder's binding, or — the +sharpest version of this — coc's `nmap gd (coc-definition)` and a new +`vim.keymap.set('n', 'gd', vim.lsp.buf.definition, ...)` both trying to own `gd`; whichever +runs **last** during config load silently wins, with no error, and it *looks* like a bug in +the new plugin rather than a stale binding from the old one. +*Detection*: `:verbose nmap gd` (repeat for every keymap that matters: `gr`, `gy`, `gi`, +`K`, `rn`, `f`, etc.) shows exactly which script/line last set the mapping — +run this for every keymap the old and new systems both touch before calling a migration step +"done." +*Mitigation*: delete the old plugin's keymap block in the **same commit** that adds the new +plugin's keymap block for that function — never let both exist simultaneously even +transiently within the branch's history. Ownership of a keybinding is 1:1 with whichever +plugin is currently active for that function, never dual-bound "just in case." + +## 5. Personal wiki dependency: vim-zettel + vimwiki + +Both are pure-vimscript plugins with no Lua rewrite and none needed. They are indifferent to +whether the surrounding config is vimscript or Lua — the only two things they need are (a) a +plugin-manager entry (lazy.nvim already manages them fine either way — the current entries are +literally `'tstapler/vimwiki'` (Tyler's own fork) and `'michal-h21/vim-zettel'`, unchanged in a +Lua tree) and (b) their `g:` variables set before/at load. Today those are set in vimscript +(`.vimrc.dein` lines 368-374: `g:zettel_format`, `g:vimwiki_list` pointing at +`~/personal-wiki/logseq/pages`). In a Lua config this is a 1:1 mechanical port — +`vim.g.zettel_format = "..."` / `vim.g.vimwiki_list = { {...} }` — either inline in +`lua/tstapler/plugins/wiki.lua` or in that spec's `init = function() ... end`. Zero semantic +risk, zero compat shim required. + +The one adjacent risk (not a Lua-vs-vimscript issue) is the `.vimsnippets` cfgcaddy multi-dest +entry pointing at a dein-specific path (`.vim/bundle/.dein/stapler-snips`, see §0) — confirm +nothing in the wiki/snippets workflow actually depends on that stale path before pruning it. + +## 6. LSP data flow: native (nvim-lspconfig/mason) vs. coc.nvim — making the coexistence risk concrete + +**Native flow:** +1. `mason.nvim` installs/manages LSP server **binaries** (`gopls`, `pyright`/`basedpyright`, + `rust-analyzer`, `vtsls`/`tsserver`) into `~/.local/share/nvim/mason/bin`, independent of + any system package manager. +2. `mason-lspconfig.nvim` bridges mason's binary names to lspconfig's server names and, on + Neovim 0.11+, can call the native `vim.lsp.enable({...})` API so servers auto-start on a + matching filetype — a declarative shift away from the older per-server + `require('lspconfig').gopls.setup{}` calls. +3. On attach, an `LspAttach` autocmd wires keymaps **once, globally** + (`vim.lsp.buf.definition`, `.references`, `.rename`, `.code_action`, etc.) rather than + duplicating keymap logic per server. +4. Diagnostics are native: `vim.diagnostic.config()` controls signs/virtualtext/underline + uniformly across every attached server, via Neovim's own `vim.diagnostic` API. +5. Completion is a *separate* concern layered on top (nvim-cmp/blink.cmp), wired via + `capabilities` passed into the server config — easy to forget as a step (server attaches + fine, hover/gd work, but completion silently stays basic because capabilities were never + advertised). + +**coc.nvim's current flow (fundamentally different plumbing, not just older syntax):** +1. coc.nvim is a single Node.js host process. "Extensions" (`coc-go`, `coc-pyright`, + `coc-rust-analyzer`, `coc-tsserver`, etc. — the ~18 entries in `g:coc_global_extensions`) + are installed and managed **by coc itself** (`:CocInstall`, stored under + `~/.config/coc/extensions`) — a closed package ecosystem parallel to, and + non-interoperable with, mason/lspconfig. +2. Those extensions wrap/embed the actual language servers and talk to coc's Node process + over its own internal RPC — diagnostics, completion, go-to-def, and rename all flow through + coc's own vimscript/Node plumbing (`CocAction`, `coc#pum#*`, `(coc-definition)`, all + visible throughout `.vimrc.dein` lines 190-364), a **completely separate code path** from + `vim.lsp.buf.*` / `vim.diagnostic.*` — not two implementations of the same API, two + unrelated systems that happen to solve the same problem. +3. **This is exactly why coexistence is dangerous, concretely**: if `gopls` is registered + both as coc's `coc-go` extension *and* as a native mason/lspconfig server for the `go` + filetype, two independent LSP client processes attach to the same buffer. Each pushes its + own diagnostics (duplicate signs), each can claim the same keymap (`gd` bound to both + `(coc-definition)` and an `LspAttach`-wired `vim.lsp.buf.definition` — see §4D for + which wins), and both try to drive the same completion popup (coc's `coc#pum#visible()` + omnifunc-driven flow vs. nvim-cmp's LSP source) fighting over ``/``. There is no + supported partial state — "half coc, half native LSP" for a single filetype is not a + degraded-but-working mode, it's actively broken. This is why requirements.md calls the + vimscript-vs-Lua decision "load-bearing for the whole plan": the cutover must be atomic — + either whole-repo at once, or filetype-by-filetype with strict removal of the old + extension the same commit the new server is added (§4A) — never a lingering hybrid. diff --git a/project_plans/neovim-hardening/research/build-vs-buy.md b/project_plans/neovim-hardening/research/build-vs-buy.md new file mode 100644 index 00000000..a87187a8 --- /dev/null +++ b/project_plans/neovim-hardening/research/build-vs-buy.md @@ -0,0 +1,110 @@ +# Research: Build vs. Buy — Neovim Config Base + +**Question**: Should `neovim-hardening` build a config from scratch, adopt/fork a pre-built distribution, or take a hybrid approach? + +**Two factors that rule options in/out, per the requirements doc**: +1. **cfgcaddy constraint** — whatever lives at `~/.config/nvim` must be plain files that `.cfgcaddy.yml` can symlink from the dotfiles repo (today: a single `.vimrc` symlinked to both `~/.vimrc` and `~/.config/nvim/init.vim`).

Net: actively maintained, occasional slow patches. +- **License**: Apache-2.0 (LazyVim repo). +- **Opinionated/customizable**: Highly opinionated defaults (leader = ``, its own keymap scheme, UI chrome via bufferline/noice/etc.) but customization is a first-class, well-documented mechanism — `lua/plugins/*.lua` files merge/override specs, and an "extras" system toggles curated language/feature bundles on and off. +- **4 priority areas**: All four are first-class and well-documented. LSP via nvim-lspconfig + mason (`lang.go`, `lang.python`, `lang.rust`, `lang.typescript` extras).

Custom filetype tabstop/shiftwidth settings and personal snippets are just more files under `lua/config`/`after/ftplugin` — no conflict, but 100% additive work regardless of base. +- **Pros**: Most actively developed, best-documented DAP story of the three, largest "extras" catalog directly mapped to the 4 priority areas, biggest community (so answers exist for edge cases). +- **Cons**: Adopting it swaps the *current* problem (an unaudited ~50-plugin surface) for a *new* large plugin surface — LazyVim's default install pulls in many UI/QoL plugins beyond the 4 priority areas (bufferline, noice, dashboard, which-key, etc.). That cuts against the stated Success Metric of "no redundant plugins serving the same function" and a deliberately audited, minimal config — the distro reintroduces sprawl at a different level of abstraction. Every default (leader key, keymaps, UI) that doesn't match Tyler's decade of `,`-leader muscle memory has to be actively found and overridden, which is a review burden in itself. +- **Verdict**: **Viable**, not Recommended. Technically compatible with cfgcaddy (contrary to the pre-research assumption) and has the strongest DAP/LSP/extras story, but its size and opinionation work against the project's explicit "audit and prune for redundancy" goal and its "make it Tyler's" personalization requirement. + +### AstroNvim v4 +- **Maturity**: v4 (2024) was a full architectural rewrite around AstroCore/AstroUI/AstroLSP; actively maintained into 2026, considered one of the most polished distros available. +- **License**: MIT. +- **Opinionated/customizable**: Strong emphasis on modularity; the `astrocommunity` repo has hundreds of pre-built plugin specs (including DAP configs) that snap into the template, encouraging a "mix and match" style rather than "override the defaults" style. +- **4 priority areas**: Covered via astrocommunity packs per language (LSP, DAP, none built-in by default the way LazyVim's extras are — you opt into an astrocommunity pack per language, e.g. `pack.go`, which bundles LSP+DAP+formatting+linting together). +- **cfgcaddy fit**: Good — same thin-template architecture as LazyVim. +- **Personal-customization fit**: Similar to LazyVim; vimwiki/vim-zettel and filetype/snippet work is equally additive. +- **Pros**: Very polished, modular, strong "team config sharing" culture (astrocommunity) which happens to also work well for a personal config that wants curated language packs instead of assembling raw plugin specs. +- **Cons**: Same sprawl/opinionation concerns as LazyVim, slightly smaller community than LazyVim for troubleshooting, no meaningfully stronger case than LazyVim on the two decisive factors. +- **Verdict**: **Viable**, not Recommended — same reasoning as LazyVim; if a distro were chosen, LazyVim's larger community and clearer per-extra DAP wiring is marginally the better bet between the two. + +### NvChad +- **Maturity**: v2.5 (starter-config rewrite) actively maintained; has a documented history of breaking changes between major versions (the v2.0→v2.5 move was itself a breaking rewrite of the config model). +- **License**: GPL-3.0 (notably copyleft — different from LazyVim/AstroNvim's permissive licenses; not a practical problem for a personal config that isn't redistributed, but worth flagging since the other two are MIT/Apache). +- **Opinionated/customizable**: Optimized for performance and visual polish over configurability; less of a "curated extras" story for LSP/DAP than LazyVim. +- **4 priority areas**: Weakest out-of-the-box DAP/LSP story of the three — more manual assembly required than LazyVim's extras or AstroNvim's community packs. +- **cfgcaddy fit**: Good under v2.5's starter-config model (same architecture shift as the other two); conflicts under pre-2.5 install instructions. +- **Cons**: History of breaking changes between major versions means periodic re-adaptation work even after initial setup — a maintenance tax that works against a "set it up once, dogfood for a week" goal. Weaker DAP/debugging story than LazyVim for the two priority languages (Go, Python). +- **Verdict**: **Not recommended**. No advantage over LazyVim/AstroNvim on the two decisive factors, and it's weaker specifically on DAP — the single most fragile, highest-priority requirement in this project. + +--- + +## Option 2: kickstart.nvim as a fork/adapt base + +- **Maturity**: ~30k stars, ~45k forks (unusually high fork:star ratio — a direct signal that people follow its "fork this" instructions rather than star-and-move-on). Actively committed as recently as June 2026. +- **License**: MIT. +- **Philosophy**: explicitly *not* a distro. It is "a launch point for your personal nvim configuration" — a single, heavily-commented `init.lua` (plus optional `lua/kickstart/plugins/*.lua` add-on stubs for e.g. debug/lint) meant to be read top-to-bottom, forked, and directly edited — not installed and left to auto-update. The maintainers are explicit that it is a teaching reference, not a framework: "distros are great for inspiration... create your own config." +- **cfgcaddy fit**: Excellent — trivially so. There is no "distro core" to fetch or import; every line kickstart gives you is a plain file you own outright from day one. This is functionally identical to symlinking `.vimrc` today, just split into `init.lua` + a `lua/` tree. +- **Personal-customization fit**: Excellent, for the same reason. There's no distro opinion to override — the leader key, filetype settings, wiki plugin wiring, and snippet paths are added directly into a structure Tyler fully understands, because kickstart's whole design intent is that the person reading it becomes the author. +- **Pros**: Zero cfgcaddy conflict, zero distro-opinion fighting, actively maintained as a *reference* (bug fixes/updates to the teaching pattern still land), includes a debug.lua stub already wired for nvim-dap + mason that's a legitimate starting point rather than a blank page. Much smaller surface area to audit than a full distro — aligns with the project's "prune to a minimal, audited plugin set" goal. +- **Cons**: Provides far less out-of-the-box scaffolding than LazyVim's extras for DAP/LSP per-language — Tyler (or this project's planning/implementation phases) still has to assemble and validate the Go/Python/Rust/TS-JS LSP+DAP wiring largely by hand, using kickstart's stub and LazyVim/AstroCommunity specs as reference material rather than a working default. +- **Verdict**: **Recommended** as the structural starting skeleton. It resolves both decisive factors better than any full distro, at the cost of more manual assembly work for the 4 priority areas — which the "from scratch" option below addresses using the same reference material. + +--- + +## Option 3: From-scratch build (nvim-lspconfig, treesitter, telescope/fzf-lua, nvim-dap, gitsigns/neogit assembled directly) + +- **cfgcaddy fit**: Excellent — identical reasoning to kickstart.nvim; there's no external "distro" dependency at all, just plain Lua files under a structure this project designs. +- **Personal-customization fit**: Excellent — maximum control, zero distro defaults to discover and override. The `,` leader, filetype settings, wiki integration, and snippet paths carry over unchanged in spirit from the current `.vimrc`. +- **Pros**: Full control; matches the explicit requirements-doc ask to produce a reasoned vimscript-vs-Lua recommendation rather than inherit someone else's answer; the resulting config only contains what the audit says is needed, directly satisfying "no redundant plugins" and "zero dead files" success metrics; nothing to fight. +- **Cons**: Most upfront effort of any option, particularly DAP adapter wiring — the requirements doc's own Rabbit Holes section flags DAP setup as "often the most fragile part of a modern config," and building it from zero (vs. adapting a known-working `nvim-dap-go`/`nvim-dap-python` spec) is the single biggest place this could slip the 3–6 week appetite. +- **Note**: this option and Option 2 (kickstart) are not fully distinct in practice — kickstart *is* a from-scratch build with a documented, actively-maintained skeleton and a debug.lua starting stub. The realistic version of "from scratch" for this project is "kickstart's skeleton, then assemble the rest using community-tested reference snippets" (see Option 4). +- **Verdict**: **Recommended**, effectively merged with Option 2 — use kickstart.nvim's skeleton as the literal starting point rather than writing `init.lua` bootstrapping (lazy.nvim install, base options) from a blank file, then assemble LSP/DAP/fuzzy-find/git directly rather than importing a distro's plugin bundle. + +--- + +## Option 4: LLM-generated plugin configs vs. adapting community-tested snippets + +There is a real, non-hypothetical risk in hand-writing Neovim Lua plugin specs from an LLM's training data alone, specifically for the plumbing pieces (not the personal pieces): + +- **API drift risk is concrete here, not generic**: Neovim 0.11 (the version floor this project targets) introduced the native `vim.lsp.config()` / `vim.lsp.enable()` API that is displacing the older `require('lspconfig')..setup{}` pattern many training corpora are saturated with. An LLM hand-writing LSP setup from memory is more likely to reach for the older, still-technically-working-via-back-compat idiom than the current idiomatic path, or to invent plausible-looking but wrong `opts` keys for fast-moving plugins (DAP adapter tables, mason `ensure_installed` package names, treesitter parser lists) where the correct value is a specific string that must match what the tool actually registers. +- **Community-tested snippets are the better source for boilerplate/plumbing**: LazyVim's `lang.go`/`lang.python`/`lang.rust`/`lang.typescript` extras, AstroCommunity's per-language packs, and kickstart.nvim's own `lua/kickstart/plugins/debug.lua` are all continuously exercised by large user bases against current plugin versions. Adapting these for the mechanical parts (Delve/debugpy adapter registration, Mason package names, treesitter `ensure_installed` lists, gitsigns default keymaps) is lower-risk and faster than reasoning them out from scratch, and doesn't forfeit any of the "from scratch" benefits above — the resulting config is still fully-owned, auditable, and distro-independent, since these are single-file references to copy and adapt, not a dependency to import. +- **Where bespoke config legitimately cannot come from any reference**, regardless of base chosen: the `,` vs `` leader decision (a decade of muscle memory — no community snippet can decide this), the 12+ custom per-filetype `tabstop`/`shiftwidth` settings already encoded in `.vimrc`, the vimwiki/vim-zettel wiring to `~/personal-wiki/logseq/pages` (explicitly out-of-scope-to-improve but in-scope-to-preserve), and the personal-snippet path wiring to `~/.vimsnippets`. These are Tyler-specific facts no distro, kickstart fork, or community snippet encodes — they have to be hand-authored and reviewed in the planning/implementation phases no matter which base is chosen. +- **Verdict**: Use community-tested snippets (LazyVim extras / AstroCommunity packs / kickstart's debug.lua) as reference material for the plumbing during implementation, rather than having an LLM (or Tyler) write DAP/LSP/mason wiring from a blank page. Treat the personal-preference items above as always-bespoke, always-hand-reviewed, independent of that choice. + +--- + +## Option 5: Fork/adapt a specific existing personal dotfiles repo + +- **Example evaluated**: ThePrimeagen's `init.lua`/`.dotfiles` — arguably the most well-known personal Neovim config in the community, with multiple public forks (e.g. `enlightened/init.lua`) demonstrating the pattern is common. +- **Pros**: Concrete existence proof that "fork a specific person's config" is a viable, common pattern; can be useful as inspiration for structuring `lua/` modules or specific plugin choices. +- **Cons**: ThePrimeagen's config uses Packer, a plugin manager that has been unmaintained since 2023 — forking it directly would require swapping in lazy.nvim anyway, eliminating most of the time-savings of forking. More fundamentally, any specific individual's dotfiles encode *their* leader key, *their* keybinding scheme, and *their* plugin choices — adopting one wholesale means undoing as much personalization work as adopting a distro, just with a less-maintained, less-documented starting point and no community support channel. It offers strictly less than kickstart.nvim, which is purpose-built and actively maintained as a generic fork base, while a specific person's dotfiles are not. +- **Verdict**: **Not recommended** as the literal fork base. **Viable** only as ad hoc inspiration/reference for specific snippets during implementation (same role as the LazyVim/AstroCommunity specs in Option 4) — not as a structural starting point over kickstart.nvim. + +--- + +## Summary Recommendation + +**Hybrid, not a binary build-vs-buy choice**: use kickstart.nvim's actively-maintained, MIT-licensed, plain-file skeleton (Option 2) as the literal starting point instead of bootstrapping `init.lua` from zero — it is functionally "from scratch with a documented on-ramp" (Option 3) and both resolve the cfgcaddy and personal-customization constraints identically and better than any full distro. Then assemble the 4 priority areas (LSP, DAP, fuzzy-find, git) by adapting community-tested reference snippets from LazyVim's language extras, AstroCommunity packs, and kickstart's own debug.lua (Option 4) rather than hand-rolling adapter/mason/treesitter plumbing from an LLM's possibly-stale training data. Do not adopt LazyVim/AstroNvim/NvChad wholesale (Option 1) — they are now technically cfgcaddy-compatible (a real update to the pre-research assumption in `requirements.md`), but their scale and opinionation cut directly against this project's own success metrics (audited, non-redundant, minimal plugin set) and personalization requirement. Do not fork a specific person's dotfiles repo (Option 5) — no advantage over kickstart.nvim as a structural base, useful only as occasional reference alongside the distro specs. + +**Decisive factors recap**: +- cfgcaddy: all options are now technically compatible (the "distro owns ~/.config/nvim" concern is resolved as of current distro versions) — this factor no longer rules anything out, but doesn't favor a full distro either since kickstart/from-scratch are just as compatible with zero extra indirection. +- Personal customization: this is the factor that actually discriminates — it favors kickstart/from-scratch (nothing to override) over full distro adoption (a lot to override) and over forking a stranger's dotfiles (someone else's overrides to undo). diff --git a/project_plans/neovim-hardening/research/features.md b/project_plans/neovim-hardening/research/features.md new file mode 100644 index 00000000..8d2ce3f1 --- /dev/null +++ b/project_plans/neovim-hardening/research/features.md @@ -0,0 +1,128 @@ +# Research: Feature Landscape — "IntelliJ-parity Neovim" (2025-2026) + +Agent 2 (Features) — Phase 2 research for `neovim-hardening`. + +## Existing config context (for calibration) + +Read directly from the worktree before researching: + +- `.vimrc.plug` (the file `.vimrc.dein` symlinks to) is **already on `lazy.nvim`**, not dein/vim-plug as the requirements doc's baseline language implies — the plugin *manager* migration to Lua has already happened at the bootstrap level.

Hardest IntelliJ features to replicate, and what closes the gap today + +| IntelliJ feature | Neovim 2025-2026 answer | Maturity / caveat | +|---|---|---| +| Extract method/variable, inline, move statements | `ThePrimeagen/refactoring.nvim` (LSP + treesitter based; the closest thing to a general-purpose refactor library) and the newer, narrower `mraspaud/lsp-refactor.nvim` (extract_function, extract_variable, move_statements_into_function/to_callers — explicitly Python/Rust/Go only) | These are heuristic, treesitter-node-based transforms, not full semantic refactors like IntelliJ's — they work well for single-file extract/inline but are not as bullet-proof as IntelliJ's AST-verified transforms. Expect occasional manual cleanup after extract-method in complex code. | +| Safe rename across files | LSP `textDocument/rename` via `vim.lsp.buf.rename()` — this is the one place Neovim is genuinely at parity with IntelliJ, because it delegates entirely to the language server (gopls, rust-analyzer, pyright, vtsls/tsserver all implement it solidly) | Quality is a function of the LSP server, not the editor — gopls/rust-analyzer rename is considered production-grade; ts-server rename across a monorepo can miss files outside the detected project root (see §3). | +| Call hierarchy (incoming/outgoing calls) | Built-in `vim.lsp.buf.incoming_calls()` / `outgoing_calls()`, or nicer UIs via `lspsaga.nvim` (`Lspsaga incoming_calls`) or `jmacadie/telescope-hierarchy.nvim` | **Known gap**: both Neovim's built-in implementation and Trouble.nvim only display one level of the hierarchy at a time (you re-invoke per node) rather than IntelliJ's expandable tree-in-a-panel. Functional but noticeably clunkier than IntelliJ's Ctrl+Alt+H. | +| Structural search-and-replace (SSR) | `MagicDuck/grug-far.nvim` — supports both ripgrep (text/regex) and **ast-grep** as a backend, giving genuine structural (AST-pattern) search-and-replace in one unified buffer UI. LazyVim replaced `nvim-spectre` with `grug-far.nvim` for this reason (better UI, ast-grep support). | This is the best current answer to IntelliJ's SSR dialog. `nvim-spectre` is the older, still-common alternative but is regex/text-only — no structural matching. Tyler's CLAUDE.md already prefers `ast-grep`/`sg` for structural search, so `grug-far.nvim` is a natural fit and reuses a tool already in his workflow. | +| Inline error/warning gutters + as-you-type diagnostics | Built-in `vim.diagnostic` virtual text/signs are functional but visually noisy (multi-line, pushes text). `rachartier/tiny-inline-diagnostic.nvim` is the current community favorite for a compact, IntelliJ-like inline diagnostic (single-line, doesn't shift code, actively maintained through 2025-2026). | Straightforward win — this is a pure UX plugin layered on the LSP client's diagnostics, no server-side dependency. | +| Parameter hints / inlay hints | Native as of Neovim 0.10+ via `vim.lsp.inlay_hint.enable()` — no plugin needed, works directly off LSP `textDocument/inlayHint` (gopls, rust-analyzer, pyright/basedpyright, vtsls all support it) | Straightforward native win once on a real LSP client (not available under coc.nvim's older protocol handling without extra config). | +| Quick-fix / code actions | Native `vim.lsp.buf.code_action()`; UX sugar via lspsaga's "lightbulb" indicator showing a code action is available at cursor, similar to IntelliJ's yellow bulb | Works well; the lightbulb indicator is the main "unstated need" gap vs. raw code action calls (see §4). | +| Breadcrumbs (symbol path in header) | `lspsaga.nvim`'s winbar breadcrumb feature, or `Bekaboo/dropbar.nvim` (dedicated breadcrumb/winbar plugin), both LSP-symbol-driven | lspsaga's winbar had reported gaps (older versions showed only file path, not symbol path) — verify current lspsaga version behavior in planning/spike; `dropbar.nvim` is a narrower, purpose-built alternative if lspsaga's winbar underdelivers. | +| "Recent Files" / "Recent Locations" | `telescope-recent-files` (tracks recently opened buffers), `telescope-frecency` (frecency-ranked — most useful proxy for IntelliJ's algorithm), or `fff.nvim` (frecency + git-status-aware fuzzy file picker) | Multiple viable options; frecency-based ranking is the closest conceptual match to IntelliJ's "Recent Files" (recency + frequency weighted, not just MRU). | +| Structural code folding | Native treesitter-based folding (`foldmethod=expr`, `foldexpr=nvim_treesitter#foldexpr()`) plus `kevinhwang91/nvim-ufo` for a much better fold UI/preview | Treesitter folding alone is serviceable; `nvim-ufo` is the widely-recommended layer for IntelliJ-like fold previews and performance. | +| Minimap | `Isrothy/neominimap.nvim` (successor to the older, less-maintained `codewindow.nvim`) — shows code structure, diagnostics, and git changes in the minimap | Genuinely optional/cosmetic; not load-bearing for the "replace IntelliJ" goal, low priority. | + +**Bottom line for this section**: LSP-delegated features (rename, hover, definition, references, inlay hints) are at or near parity today given a real LSP client (i.e., contingent on the vimscript-vs-Lua / coc-vs-native-LSP decision made elsewhere in this research). The genuine, still-open gaps vs. IntelliJ are (a) call-hierarchy as a persistent expandable tree rather than one-level-at-a-time, and (b) fully-verified multi-step semantic refactors (extract-interface, safe-delete-with-usage-check) — these remain heuristic/best-effort in the Neovim ecosystem, not solved. + +--- + +## 2. Prior art: what LazyVim / NvChad / AstroNvim / kickstart.nvim actually ship + +- **LazyVim** is the community consensus pick for 2025-2026: largest ecosystem, most active maintainer (folke, who also wrote `lazy.nvim` and `grug-far.nvim`), and an **extras system** (`:LazyExtras`) that is directly relevant to this project's scope — there are ready-made, maintained extras for `lang.go`, `lang.rust`, `lang.python`, `lang.typescript`, and `dap.core` + per-language DAP wiring. Each language extra bundles: LSP server config (nvim-lspconfig), treesitter parser, formatter (conform.nvim), linter (nvim-lint), DAP adapter wiring, and test runner (neotest) integration — i.e., almost exactly the shape of what this project's scope calls for, per language, already assembled and maintained upstream. + - Go extra: gopls + delve (via nvim-dap-go) + neotest-golang. + - Rust extra: `rustaceanvim` (the actively-maintained successor to the now-archived `rust-tools.nvim`) + codelldb. + - Python extra: choice of pyright/basedpyright + ruff, debugpy, venv-selector.nvim (virtualenv switching — a real gap in the old coc-pyright setup). + - TypeScript extra: choice of `vtsls` (VSCode's own TS extension repackaged as an LSP — richer than `typescript-language-server`, and LazyVim's current default) or `tsgo`, js-debug-adapter, oxc/biome as a fast linter/formatter option. +- **NvChad**: leaner, more "starting framework" than batteries-included distro; less prescriptive about DAP/refactor tooling out of the box — better fit for someone who wants to hand-assemble than someone who wants per-language packages pre-wired. +- **AstroNvim**: closer to LazyVim in scope, ships DAP by default in many of its language packs (arguably even more DAP-eager out of the box than LazyVim, which gates DAP behind opting into the extra). Strong community/Discord, actively maintained. +- **kickstart.nvim**: intentionally a single-file, heavily-commented *starting point*, not a distribution — no built-in DAP/refactor/git-UI opinions; you build it yourself. Good if the goal were "learn Lua config from scratch," less good as a fast path to the specific feature set this project needs (search didn't surface direct kickstart-vs-others feature comparisons for 2025-2026; treat as the "roll your own" baseline rather than a competitor to LazyVim/AstroNvim on features). +- **LunarVim**: explicitly called out in current community commentary as stalled/unmaintained as of 2026 — do not consider as a base. + +**Differentiation vs. marketing**: the genuinely differentiated thing LazyVim/AstroNvim offer over a from-scratch config is *maintained glue code per language* (root-dir detection quirks, DAP adapter path discovery, formatter/linter wiring) — this is exactly the "fragile, time-consuming" work flagged as a Rabbit Hole in requirements.md. The lazy-loading and UI polish (dashboard, which-key, statusline) are marketing-grade nice-to-haves, not differentiators for this project's actual goals. Given Tyler's config already has meaningful personal customization (vim-zettel/vimwiki workflow, custom filetype rules, personal snippets, `vim-oscyank` tmux integration), **forking wholesale is higher-risk than adopting the per-language extras pattern (or literally vendoring LazyVim's language-extra Lua files) inside a custom config** — this is a build-vs-adopt tradeoff to make explicit in planning, not just "distro vs. no distro." + +--- + +## 3. Edge cases / failure modes specific to this migration + +- **Multi-root / monorepo projects**: `nvim-lspconfig`'s default root-marker search is described upstream as "breadth-first" — it can find multiple matching root markers across a monorepo rather than stopping at the nearest ancestor, causing an LSP server to attach at the wrong (too-high) root. The LSP client tracks a root per-buffer, so different files in the same monorepo can legitimately get different roots — this is workable but requires a custom `root_dir` function (checking for `pnpm-workspace.yaml`, `nx.json`, `go.work`, etc.) rather than relying on defaults, especially for the TS/JS extra where monorepos are most common. Flag as a planning-phase task, not an assumption. +- **Projects without a clear root marker**: any bare-directory Python/Go script folder with no `go.mod`/`pyproject.toml`/`.git` present will fail root detection outright — the LSP either won't attach or attaches with `root_dir = nil` (single-file mode), which silently degrades cross-file features (no workspace-wide rename/find-references). Needs an explicit "single-file LSP mode" fallback config, not silent failure. +- **Large files**: nvim-treesitter has a long-standing, still-relevant performance issue on very large files (documented example: a 90k-line C header) — the community answer is a size-based cutoff to skip treesitter highlighting/folding above a threshold, and/or restricting the parsed context to a window around the cursor. This needs an explicit `max_filesize` guard in the treesitter config (LazyVim ships one by default; a from-scratch config must add it manually or risk visible input lag on large generated files — a real risk given monorepo generated code in Go/TS). +- **Remote/SSH editing**: no single dominant, mature solution yet. Options as of 2025-2026: `remote-ssh.nvim` (runs LSP on the remote host, edits locally — addresses the specific "LSP feels laggy over SSH" problem) vs. `distant.nvim`/SSHFS-style approaches (filesystem ops happen remotely, avoiding chatty round-trips for file-heavy operations). Native Neovim itself has an open GSoC 2026 discussion and issue thread about building first-class remote-dev support, meaning **this is explicitly not a solved problem upstream yet** — if Tyler does real SSH-based work, budget this as a known-rough edge rather than "install a plugin and done." +- **Projects mixing multiple languages** (e.g., a Go backend + TS frontend in one repo): each language's LSP client attaches independently per buffer/filetype, which works fine in principle, but root-detection edge cases (above) compound — a mixed-language monorepo is the worst case for root-marker ambiguity, since Go's marker (`go.mod`) and TS's marker (`package.json`/`tsconfig.json`) may sit at different directory depths in the same tree. + +--- + +## 4. Unstated needs — things an IntelliJ daily user expects and would miss + +- **Inline diagnostics as-you-type that don't reflow the line** — IntelliJ's right-margin gutter squiggle + tooltip doesn't shift code; Neovim's default virtual-text diagnostics can visually push lines around. `tiny-inline-diagnostic.nvim` specifically addresses this non-intrusiveness. +- **A visible "code action available" indicator (lightbulb)** — without it, discovering that a quick-fix exists requires manually invoking `code_action()` speculatively; IntelliJ's yellow bulb makes this passive/glanceable. lspsaga provides this; worth calling out explicitly since it's easy to end up with code actions "working" but undiscoverable. +- **Breadcrumbs / symbol path in the window header** — useful for orientation in large files; not critical but a real "oh I miss that" moment coming from IntelliJ. Cheap to add (`dropbar.nvim` or lspsaga winbar). +- **Persistent per-project sessions (reopen exactly where you left off, per git branch)** — `persisted.nvim` / `folke/persistence.nvim` / `coffebar/neovim-project` all solve this; `persisted.nvim` and `neovim-project` both specifically support **per-git-branch session state**, which is a closer match to IntelliJ's per-branch-aware window/tab restoration than plain session managers. This is a real unstated need — IntelliJ's "reopen last project state" is invisible until it's gone. +- **Frecency-ranked recent files, not just MRU** — `telescope-frecency` / `fff.nvim` reproduce IntelliJ's "Recent Files" ranking algorithm (recency + frequency), which behaves noticeably better than a flat most-recently-used list once a project has been open a while. +- **Structural code folding done well (fold preview, not just fold/unfold)** — `nvim-ufo` gives fold-content preview on hover, closer to IntelliJ's inline collapsed-block preview than bare treesitter folding. +- **Minimap** — genuinely optional; lowest-priority item on this list, listed for completeness (`neominimap.nvim`). +- **"Did you mean" typo suggestions** — no direct equivalent surfaced in research; this is generally handled implicitly by completion-engine fuzzy matching (nvim-cmp/blink.cmp) rather than a dedicated feature. Worth noting as a gap that likely doesn't need a dedicated plugin — LSP-driven completion with fuzzy matching covers most of what IntelliJ's typo-correction does in practice. +- **Virtualenv/interpreter switching for Python** — not in the original requirements list but surfaced repeatedly in LazyVim's Python extra (`venv-selector.nvim`); the current coc-pyright setup has no equivalent, and this is exactly the kind of thing a daily Python/IntelliJ (PyCharm-adjacent) user would silently miss without knowing to ask for it up front. + +--- + +## 5. vimwiki / vim-zettel compatibility risk with a modernized Lua/treesitter config + +This is the sharpest concrete risk surfaced in research, because Tyler's current config already has non-default settings that increase collision surface: + +- **Filetype override collision**: `.vimrc` (line ~205) has a bare autocmd forcing `*.md`/`*.markdown` → `filetype=mkd` globally, *outside* of vimwiki's own filetype handling. vimwiki's own list config additionally sets `'ext':'.md'` for the personal-wiki path specifically (i.e., vimwiki buffers under `~/personal-wiki/logseq/pages` want `filetype=vimwiki`, but the global autocmd is racing it toward `mkd`). This is a **pre-existing latent bug/fragility**, not something introduced by modernization — but adding treesitter-markdown or a markdown LSP (e.g., `marksman`) makes the failure mode worse, not better, because both of those attach based on filetype/extension and will silently do the wrong thing (or nothing) if `filetype` isn't consistently `vimwiki` for wiki pages. +- **Treesitter markdown parser not auto-attaching**: current community reports (2025) show the treesitter markdown parser sometimes requires manually calling `vim.treesitter.start(0, "markdown")` — it doesn't always auto-attach the way older regex-based syntax highlighting did. Combined with the filetype-override issue above, this raises real risk that either (a) treesitter never activates on wiki pages (silent, but low-severity — no different from today), or (b) it activates and its markdown grammar's opinions about e.g. embedded/injected-language code blocks conflict with vimwiki's own syntax highlighting for the same buffer, per the embedded-language-highlighting bug reports found in `neovim/neovim` discussions (injected-language buffers can break sibling-language highlighting). +- **No LSP-markdown-vs-vimwiki conflict was found in the wild** in this research — no evidence of `marksman` or similar markdown LSP servers actively fighting vimwiki's own syntax/keymapping layer; the realistic risk is confined to **treesitter highlighting/filetype interaction**, not LSP. +- **Recommendation for planning phase**: (1) do not add a markdown LSP server or treesitter-markdown highlighting without first explicitly excluding vimwiki buffers (e.g., `vim.treesitter.language.register` guarded by a check that `&filetype != 'vimwiki'`, or simply not enabling treesitter for the `vimwiki` filetype at all — vimwiki's own syntax file already handles wikilinks/checkboxes/etc. that a generic markdown grammar doesn't understand); (2) fix the pre-existing `*.md` → `mkd` global override collision as a small, explicitly-scoped cleanup, since it's already fragile and out-of-scope creep is easy to avoid by treating it as a "don't break it further" fix rather than a redesign; (3) since vimwiki/vim-zettel are vimscript plugins with no Lua rewrite in progress (none surfaced in research), they will keep working unmodified under `lazy.nvim` regardless of the vimscript-vs-Lua decision for the rest of the config — `lazy.nvim` loads vimscript plugins natively, so this is a low-risk area as long as filetype detection stays correct. + +--- + +## Sources + +- [lsp-refactor.nvim](https://codeberg.org/mraspaud/lsp-refactor.nvim)

(Pitfalls) +**Scope**: What goes wrong in practice when migrating a decade-old vimscript+coc.nvim config (lazy.nvim, ~50 plugins, nvim 0.11.6) toward native LSP/treesitter/DAP, for a solo daily driver across Go/Rust/Python/TS-JS. + +--- + +## 1. coc.nvim → native LSP migration pitfalls + +**The core hazard is well-documented and matches the requirements' own Feasibility Risk**: coc.nvim and the native LSP client cannot cleanly run side-by-side for the same language server. coc.nvim spawns its own `coc-*` extension processes (often wrapping the same `gopls`/`rust-analyzer`/`pyright`/`tsserver` binaries) that attach to the buffer independently of anything `vim.lsp` or `nvim-lspconfig` starts. If both are pointed at the same filetype simultaneously: + +- **Duplicate diagnostics**: two LSP clients publish `textDocument/publishDiagnostics` for the same file, so virtual text and the loclist/quickfix show every issue twice. +- **Competing completion popups**: coc's own popup menu (`coc#refresh()`) and native `vim.lsp` completion (or nvim-cmp/blink.cmp) both try to render on `InsertCharPre`/`TextChangedI`, causing flicker, wrong-item-selected bugs, or the two popups fighting for the same z-order. +- **Keymap collisions**: `gd`, `gr`, `K`, `rn` are the exact bindings both ecosystems expect to own. coc.nvim deliberately does **not** set these itself (to "avoid conflict with other plugins" — confirmed on the coc.nvim README/discussions), which means *your own* mappings currently call `coc#rpc#...` functions. If lspconfig/native LSP is added without first deleting the coc-era mappings, the last `nnoremap` registered silently wins and the other system's binding becomes dead code — the classic "why isn't this working" mid-migration confusion. +- **Diagnosing which system currently owns a key**: `:verbose nmap gd` / `:verbose nmap K` shows the source file/line of the winning mapping — the standard debugging move called out repeatedly in migration writeups (gierdo's blog, mark-story.com). + +**Snippet engine migration** (coc-snippets, which itself wraps UltiSnips/vim-snippets syntax) → native `vim.snippet` (nvim 0.10+) or LuaSnip: +- coc-snippets supports both its own snippet syntax and UltiSnips syntax via a `pythonx`-dependent provider; if the migration path is coc-snippets → LuaSnip, existing personal UltiSnips-style snippets are **not directly compatible** — `mireq/luasnip-snippets` exists specifically because vim-snippets/UltiSnips-format snippets need conversion to LuaSnip's Lua-table format. Personal snippets accumulated over a decade should be inventoried before ripping out coc-snippets, or they silently stop being available. +- LuaSnip is the more mature choice for nvim-cmp/blink.cmp integration; native `vim.snippet` (0.10+) is lighter but has less LSP-snippet placeholder/choice-node polish as of nvim 0.11.6 — worth prototyping with one real Go/TS snippet before committing. + +**How people get stuck mid-migration** (recurring pattern across the sources): they add nvim-lspconfig/mason for one language to "try it out," get diagnostics/completion partially working, but don't rip out the corresponding `coc-` extension or the coc keymaps — producing a hybrid that's strictly worse than either pure setup (duplicate signs in the sign column, `K` sometimes showing coc's hover and sometimes native hover depending on which loaded last). The nvim-lspconfig migration issue thread (#3494) and neovim/neovim discussion #35942 confirm this exact failure mode is common enough that maintainers explicitly warn against partial adoption — **the requirements.md rabbit-hole callout ("easy to half-migrate") is accurate and should be treated as the primary execution risk, not a hypothetical.** +- Mitigation: migrate **one language at a time, fully** (disable the coc extension for that filetype entirely, remove its coc keymaps/autocmds, verify with `:checkhealth vim.lsp` that exactly one client is attached via `:LspInfo` before moving to the next language) rather than flipping a global "use native LSP" switch. + +--- + +## 2. DAP setup pitfalls (nvim-dap + adapters) + +Confirms the requirements' Feasibility Risk that DAP setup is "the most fragile part of a modern config" — budget real time. + +**Go / delve**: +- `dlv` must be resolvable by nvim-dap's adapter config, but relying on `$PATH` alone is a common failure point when delve is installed via Mason into `~/.local/share/nvim/mason/bin` rather than `go install`. The reliable pattern is to hardcode the adapter's `command` to `vim.fn.stdpath("data") .. "/mason/bin/dlv"` (or the `go install` GOBIN path) rather than assuming PATH inheritance — shells launched from GUI app launchers or from `nvim` invoked via a wrapper script often don't have the same PATH as an interactive shell. +- Remote-attach mode (`dlv dap` server + attach) has known rough edges (go-delve/delve#3029) — prefer the simpler launch-mode config unless remote debugging is actually needed. + +**Python / debugpy**: +- `nvim-dap-python`'s venv auto-detection checks `$VIRTUAL_ENV`, `$CONDA_PREFIX`, and `venv`/`.venv`/`env`/`.env` directories relative to CWD or the LSP root_dir — but this **only works if nvim is launched with the venv already active or the venv directory follows one of those exact names**. A poetry/pipenv project with a venv in a non-standard location (e.g. pipenv's hashed path outside the project dir) will silently resolve to system Python and then fail to import `debugpy`, or worse, debug against the wrong interpreter without an obvious error. A custom `resolve_python()` function (or explicit `pythonPath` per launch config) is the robust fix, not the default auto-detect. +- On Debian/Ubuntu, Mason's debugpy install can fail if `python3-venv` isn't installed system-wide (a genuine footgun since the failure looks like a Mason bug, not a missing system package) — worth checking with `python3 -m venv --help` before troubleshooting the Neovim side. +- Test with `/path/to/python -m debugpy --version` to isolate "wrong Python" from "nvim-dap config" bugs. + +**Rust / codelldb vs rust-analyzer**: +- Community consensus (rustaceanvim maintainer guidance, multiple threads) is to **not** let Mason manage `rust-analyzer` — version drift between a Mason-pinned rust-analyzer and the project's actual Rust toolchain version causes subtle diagnostic/macro-expansion mismatches that are hard to distinguish from real bugs. Prefer `rustup component add rust-analyzer` (toolchain-matched) over `:MasonInstall rust-analyzer`. +- codelldb (the DAP adapter, separate from rust-analyzer) is comparatively more decoupled from toolchain version but still needs to match the target's debug-info format; `rustaceanvim` auto-wires nvim-dap configs on LSP attach, which reduces (but doesn't eliminate) manual codelldb path wiring. Run `:checkhealth rustaceanvim` after setup. + +**Cross-cutting DAP pitfalls**: +- **launch.json-equivalent duplication across projects**: nvim-dap configs are Lua tables per-filetype in your Neovim config, not per-project — meaning every Go/Python/Rust project shares one global launch config unless you add per-project overrides (e.g. a `.nvim.lua` local config, gated behind `exrc`/`vim.trust`, or nvim-dap's project-local `.vscode/launch.json` reader via `nvim-dap-vscode-js`-style shims). Decide up front whether per-project launch config support is in scope, since the "one config to rule all projects" default breaks as soon as two projects need different args/env/cwd. +- **Breakpoints not binding on lazy-loaded DAP plugins**: if `nvim-dap` itself is lazy-loaded on `cmd = "DapToggleBreakpoint"` or similar, a breakpoint set before the plugin loads (e.g. via a keymap that doesn't force-load first) can silently no-op. Load nvim-dap eagerly or make every DAP-related keymap force the plugin to load synchronously before calling into it (lazy.nvim's `keys` trigger handles this correctly if configured as a lazy-load trigger, but a raw keymap defined outside the lazy spec will not). + +--- + +## 3. Treesitter pitfalls + +**Parser/query version drift after nvim upgrades**: nvim-treesitter parsers are versioned independently from the plugin and from Neovim's bundled tree-sitter runtime ABI. Multiple GitHub issues (nvim-treesitter#6618, #4915) show highlighting/query breakage after a Neovim upgrade when installed parsers were compiled against an older tree-sitter ABI — the fix is always `:TSUpdate` after any nvim version bump, but this is easy to forget and manifests as confusing "highlighting just broke" reports days after an unrelated system update (e.g. `pacman -Syu` bumping neovim on Manjaro, which is this user's OS). + +**Markdown parser vs vimwiki — this is the requirements' explicit "must not break" dependency (`~/personal-wiki/logseq/pages`)**: +- Confirmed real-world conflict (nvim-treesitter#6720): vimwiki buffers throw `no parser for 'vimwiki' language` errors when treesitter folding is active, because there is no dedicated `vimwiki` tree-sitter grammar — treesitter has nothing to parse vimwiki's own syntax with, yet folding/highlighting machinery still tries. +- Separately (nvim-treesitter#5922), the **markdown parser itself has a known bug where switching between markdown buffers corrupts parse state when `foldmethod=marker`** — relevant because vimwiki files are often also `.md`-adjacent or configured with marker-based folding. +- **Concrete mitigation for this repo**: explicitly exclude the `vimwiki` filetype from treesitter's `highlight`/`indent`/`fold` module attachment (`disable = { "vimwiki" }` in the parser config, or via an `ftplugin`/autocmd that keeps vimwiki on its native vimscript syntax+folding). Do not let treesitter's generic markdown parser attach to `*.wiki` files even if the filetype detection is ambiguous. Since vim-zettel/vimwiki are explicitly out-of-scope for improvement but must not regress, the safest move is an explicit disable rule tested against the real `~/personal-wiki/logseq/pages` files before merging, not an assumption that "it'll just work." +- Nested-list folding is also independently buggy in the markdown parser (#5366) — irrelevant to vimwiki specifically but relevant if the migration also touches note-taking-adjacent markdown scratch files. + +--- + +## 4. Plugin-pruning pitfalls ("is this actually used?") + +There is no automated way to answer "is this plugin load-bearing" — none of the plugin managers (dein, lazy.nvim, vim-plug) have a reliable usage-tracking feature; `dein#check_clean()` and similar tools only detect *installed-but-not-declared* plugins, not *declared-but-unused* ones. Practical detection strategies, since none exist off-the-shelf: + +- **Keymap audit**: grep the vimscript/Lua config for every `nnoremap`/`vnoremap`/`nmap` bound to a plugin's command, then check personal muscle memory / shell history / recent usage against that list. For `vim-ctrlspace` specifically: it provides *workspace/session persistence* (multi-buffer/tab layouts saved per project) that's easy to take for granted until it's gone — if fzf.vim or Telescope becomes the single fuzzy-finder, **explicitly verify whether session/workspace persistence needs a replacement** (e.g. `mksession`-based autosave, or a dedicated session plugin) rather than assuming Telescope's session extension is a drop-in replacement — it usually isn't at feature parity. +- **`undotree`**: low interaction-surface (usually one keymap, `:UndotreeToggle`) — easy to verify usage by checking if that keymap has muscle memory attached; safe to test in isolation since it has no cross-plugin dependents. +- **`vim-surround` / `vim-repeat`**: these have a real dependency relationship — vim-surround (and several other tpope plugins) call `repeat#set()` to make `.` re-run their last action; vim-repeat is a shared *dependency*, not a competing/redundant plugin. **Do not prune vim-repeat while keeping vim-surround** — that would silently break `.`-repeat for surround operations specifically (the surround mapping still works, but pressing `.` afterward does a generic Vim repeat instead of re-running the surround command, which is a subtle enough regression to go unnoticed for a while). +- General rule for this migration: for each of the ~50 plugins, before deleting, grep the config for its command names/keymaps *and* mentally walk through "when did I last invoke this" — treat "I don't remember" as "probably safe to remove, but note it in a rollback list" rather than deleting blind, since the whole point of the worktree-based risk control is that removal mistakes are cheap to catch — but only if there's a checklist of what was removed to re-add from if a workflow gap surfaces later. + +--- + +## 5. lazy.nvim-specific pitfalls + +**Lazy-loading misconfiguration ("installed but broken")**: this is a confirmed, still-open class of bugs (lazy.nvim#858, #1049) — plugins lazy-loaded on `event` triggers can miss the actual event firing correctly, particularly when: +- A plugin needs `BufReadPre`/`BufReadPost` (which fire *before* `FileType`) but is configured to lazy-load on `FileType` — by the time it loads, the earlier events it depends on have already fired and won't re-fire, so the plugin initializes into a buffer state it never saw the setup events for. +- The fix pattern the lazy.nvim maintainers and community land on: for plugins with autocmd-dependent setup, either lazy-load on the *earliest* relevant event (usually `BufReadPre` rather than `FileType`), or accept eager-loading for anything whose setup logic is order-sensitive. `:checkhealth lazy` and manually re-triggering with `:e` (re-open current buffer) are the standard debugging techniques when a plugin "is installed, `:Lazy` shows it loaded, but it doesn't seem to do anything." + +**Plugin spec merge conflicts**: lazy.nvim merges per-plugin specs across every `lua/plugins/*.lua` file, but the merge semantics differ by key type: +- Key-value table opts (most `opts = {...}` blocks) merge automatically. +- **List-like tables (e.g. `keys`, some `opts` that are arrays) get *overridden*, not merged, by default** — a second spec file redefining `keys` for a plugin wipes out the first file's keys entirely unless `opts_extend` is explicitly declared for that key. This is a real footgun when splitting a monolithic plugin config into per-file specs (which this migration explicitly plans to do via `init.lua` + `lua/` modules) — moving from one big spec table to several files can silently drop list-valued config unless `opts_extend` is set per plugin that needs it. +- lazy.nvim resolves same-named-plugin specs across files alphabetically by filename, so whichever file sorts first becomes the "parent spec" for override purposes — an implicit, easy-to-forget ordering dependency worth documenting in the eventual plan (e.g. a numbering/naming convention for `lua/plugins/*.lua` files). + +**Startup-time regression risk**: the requirements explicitly gate on `vim-startuptime` not regressing. The main lazy.nvim-specific way to regress startup despite using a "modern" lazy-loading plugin manager is over-eager `event = "VeryLazy"` or `lazy = false` usage during migration — it's common to eager-load things "just to get them working" while debugging lazy-load trigger issues (see previous bullet) and then forget to convert them back to a proper lazy trigger before merging. + +--- + +## 6. cfgcaddy / dotfiles deployment pitfalls + +**Single-file → `lua/` directory tree migration**: the current cfgcaddy mapping is `.vimrc` → two destinations (`~/.vimrc`, `~/.config/nvim/init.vim`) — a single-file symlink. If the new config becomes `init.lua` + a `lua/` module tree, this is no longer a single-file symlink relationship: +- **Stale symlinks**: if cfgcaddy's mapping isn't updated to reflect the new file set (e.g. it still tries to symlink a `.vimrc` that no longer exists, or fails to add mappings for the new `lua/` directory), a machine that re-runs the deploy script may end up with a stale dangling symlink pointing at a deleted `.vimrc`, while the actual live config lives untracked in `~/.config/nvim/lua/`. +- **Partial syncs across machines**: if cfgcaddy maps individual files rather than the whole `lua/` directory as one unit, adding a new module file to the Lua config requires *also* remembering to add its own mapping entry — easy to forget, and the failure mode is silent (the file works locally in the worktree/dev machine but is simply absent on a second machine after `cfgcaddy sync`, because it was never added to `.cfgcaddy.yml`). Prefer mapping the whole `nvim/` directory (or `lua/` subtree) as a single recursive symlink/directory mapping over per-file entries, specifically to avoid this class of bug. +- Confirm whether cfgcaddy supports directory-level symlinking (symlink the whole directory once) vs. file-level only — this determines whether the "add a new lua module = add a new cfgcaddy entry" trap exists at all. + +**`lazy-lock.json` and `.gitignore`**: community consensus (LazyVim discussions #850, #4403) is split but leans toward **committing** the lockfile if the same config is used across multiple machines and reproducible plugin versions matter — which is exactly this user's situation (dotfiles repo, deployed to multiple machines via cfgcaddy). Recommendation: **commit `lazy-lock.json`**, not gitignore it, so that a `cfgcaddy sync` onto a second machine reproduces the exact plugin versions validated during the worktree testing phase, rather than pulling latest-and-possibly-broken versions on first install elsewhere. The alternative (gitignore it) trades reproducibility for less commit noise — not worth it here given the explicit "don't regress startup time / don't break daily-driver workflows" requirements, which are easier to guarantee with pinned versions. + +--- + +## 7. Personal risk for a daily-driver, even with the worktree mitigation + +The plan's stated risk control (build/dogfood entirely inside the `dotfiles-harden-neovim` worktree, master stays untouched, cutover is a single merge) correctly isolates *config file* risk. It does **not** fully isolate *machine state* risk. Concretely, things that can still bite mid-week despite testing only in the worktree: + +- **`~/.local/share/nvim` is shared, not branch-scoped.** Neovim's plugin install directory, Mason's installed binaries, and the lazy.nvim lockfile-resolved plugin checkouts all live in a single global `~/.local/share/nvim` regardless of which config (master's or the worktree's) is active — because both configs point `nvim` at the same data directory by default. Testing the new config installs new plugins and new Mason LSP/DAP binaries into that same shared directory. If master's coc.nvim setup and the new lspconfig/DAP setup both get exercised in the same week (e.g. switching back to master briefly for a "just get this done" moment), there's no isolation between their plugin installs — a broken Mason binary install from testing, or a lazy.nvim plugin left in a partially-updated state, can affect master's session too, because master will `require` from the same `~/.local/share/nvim/lazy/*` checkouts if the plugin names overlap. + - **Mitigation worth adding to the plan**: point the worktree's nvim invocation at an isolated `NVIM_APPNAME` (e.g. `NVIM_APPNAME=nvim-harden nvim`, which as of nvim 0.9+ isolates `~/.config/nvim-harden`, `~/.local/share/nvim-harden`, `~/.local/state/nvim-harden` automatically) rather than relying on the worktree's file content alone. Without this, "testing in the worktree" only isolates the *config source*, not the *runtime state* — which is exactly the gap the requirements' own Observability Requirements section doesn't call out. +- **The global `~/.config/nvim` symlink is a single pointer.** Since cfgcaddy deploys via symlink, `~/.config/nvim` points at one location at a time. If it's re-pointed at the worktree's config during testing, then *every* terminal session/editor invocation for the rest of that week — including ones unrelated to this project — is running the experimental config, not master's known-good one. A mid-week deadline task in an unrelated repo, opened with muscle-memory `nvim`, inherits whatever half-working state the harden branch is in that day. This is the actual "goes wrong mid-week" failure mode the requirements gesture at ("Rollback is `git checkout master`") — but `git checkout master` only fixes the symlink target on next launch, not an nvim session already running against a broken LSP/DAP setup, and it does nothing about the shared `~/.local/share/nvim` state above. +- **Mason-installed LSP/DAP binaries drift out of sync with the config that expects them.** If a Mason package is uninstalled/reinstalled or upgraded during worktree experimentation (e.g. testing a rust-analyzer version), and then master's coc.nvim setup (which may also shell out to some of the same binaries, e.g. `gopls` if coc-go wraps the same install) is used in between, version mismatches (see Section 2's codelldb/rust-analyzer warning) can appear in the *old* master config too, misattributed as a master regression when it's actually cross-contamination from worktree testing. +- **Net recommendation for the plan**: use `NVIM_APPNAME` (or equivalent full data-dir isolation) for the duration of development, not just a separate `~/.config/nvim` symlink target, so that a mid-week emergency `nvim` invocation via the normal command reliably gets master's untouched, fully-working setup with its own untouched plugin/Mason state — and so that the "worktree isolates risk" claim in the Risk Control section is actually true at the runtime-state level, not just the config-source level. + +--- + +## Sources + +- [neovim config - native lsp support instead of coc — gierdo's blog](https://gierdo.astounding.technology/blog/2024/09/19/nvim-lsp) +- [Switching to NeoVim Native LSP — Mark Story](https://mark-story.com/posts/view/switching-to-neovim-native-lsp) +- [CoC vs native LSP (mason/lspconfig) · neoclide/coc.nvim Discussion #4866](https://github.com/neoclide/coc.nvim/discussions/4866) +- [neoclide/coc.nvim](https://github.com/neoclide/coc.nvim) +- [Migrate to vim.lsp.config (non-breaking) · nvim-lspconfig#3494](https://github.com/neovim/nvim-lspconfig/issues/3494) +- [How to migrate lspconfig to 0.11 · neovim/neovim Discussion #35942](https://github.com/neovim/neovim/discussions/35942) +- [Debugging in Neovim — harrisoncramer.me](https://harrisoncramer.me/debugging-in-neovim/) +- [I'm struggling to use dlv dap with remote attach · go-delve/delve#3029](https://github.com/go-delve/delve/issues/3029) +- [Debugging in Neovim with nvim-dap — John Tobin](https://www.johntobin.ie/blog/debugging_in_neovim_with_nvim-dap/) +- [mfussenegger/nvim-dap-python](https://github.com/mfussenegger/nvim-dap-python) +- [Fixing AstroNvim Python Debugging: DAP "No Adapter" and debugpy Issues](https://vcfvct.wordpress.com/2026/05/28/fixing-astronvim-python-debugging-dap-no-adapter-and-debugpy-issues/) +- [Python Debugging Nightmare · mfussenegger/nvim-dap Discussion #1268](https://github.com/mfussenegger/nvim-dap/discussions/1268) +- [Neovim Rust debugging — more zeros than ones](https://morezerosthanones.com/posts/neovim_rust_debugging/) +- [mrcjkb/rustaceanvim](https://github.com/mrcjkb/rustaceanvim) +- [Rust/Cargo and nvim-dap/codelldb interaction · nvim-dap Discussion #671](https://github.com/mfussenegger/nvim-dap/discussions/671) +- [markdown grammar broken · nvim-treesitter Discussion #6618](https://github.com/nvim-treesitter/nvim-treesitter/discussions/6618) +- [vimwiki parser issue · nvim-treesitter#6720](https://github.com/nvim-treesitter/nvim-treesitter/issues/6720) +- [switching markdown buffers makes parsing fail with foldmethod=marker · nvim-treesitter#5922](https://github.com/nvim-treesitter/nvim-treesitter/issues/5922) +- [Markdown folds don't work correctly with nested lists · nvim-treesitter#5366](https://github.com/nvim-treesitter/nvim-treesitter/issues/5366) +- [bug: plugins lazy loaded with autocmd events don't always execute · lazy.nvim#858](https://github.com/folke/lazy.nvim/issues/858) +- [bug: some autocmd events are not fired when lazy loading · lazy.nvim#1049](https://github.com/folke/lazy.nvim/issues/1049) +- [Lazy Loading | lazy.nvim docs](https://lazy.folke.io/spec/lazy_loading) +- [Debugging and Troubleshooting | folke/lazy.nvim DeepWiki](https://deepwiki.com/folke/lazy.nvim/9.2-debugging-and-troubleshooting) +- [Structuring Your Plugins | lazy.nvim docs](https://lazy.folke.io/usage/structuring) +- [Could someone please elucidate how "merging" specs works · lazy.nvim Discussion #1706](https://github.com/folke/lazy.nvim/discussions/1706) +- [Can I add lazy-lock.json to .gitignore?

Native LSP vs coc.nvim in 2026 + +**Recommendation: migrate to native LSP (`vim.lsp` + `nvim-lspconfig`).** + +- Neovim 0.11 shipped `vim.lsp.config()` / `vim.lsp.enable()`, making native LSP + setup dramatically simpler than in the 0.5–0.10 era — this was the biggest + blocker to migrating off coc.nvim and it's now resolved. `nvim-lspconfig` itself + is transitioning to being a thin collection of `lsp/*.lua` server config files + consumed directly by the new `vim.lsp.config`/`enable` API rather than a setup + wrapper — using it alongside the new API is the currently-recommended path and + is explicitly forward-compatible. +- Community trend is unambiguous: LazyVim, kickstart.nvim, and the broad + ecosystem have standardized on native LSP + Mason for server installs. + coc.nvim discussion threads (e.g. neoclide/coc.nvim#4866) show the honest + trade-off: coc.nvim is more batteries-included out of the box, but native LSP + has caught up in capability while giving finer-grained control and one + consistent client across all languages instead of coc's separate extension + model per language. +- Migration complexity is real but bounded: coc.nvim currently provides + completion, snippets, formatting, diagnostics, and code actions all through + one plugin. Native LSP requires assembling equivalents: `nvim-lspconfig` (or + `lsp/*.lua` configs) for servers, a completion engine (see below), a snippet + engine (`LuaSnip` or Neovim 0.10+ native `vim.snippet`), and `conform.nvim` / + `nvim-lint` (or continue relying on `ale` for linting/formatting non-LSP + cases) for formatting/diagnostics that aren't LSP-native. This is the + "touches everything simultaneously" rabbit hole flagged in requirements — + plan phase should sequence it (e.g. LSP+completion first, formatting second, + snippets third) rather than one big-bang swap. +- coc.nvim and a native LSP client should **not** run the same language server + for the same language simultaneously (both will attach and produce duplicate + diagnostics/completions) — this confirms the feasibility risk in requirements. + Plan should treat this as an all-or-nothing cutover per language, not a + gradual per-language migration if both stacks are loaded at once (safest: rip + out coc.nvim as one atomic step, don't try to dual-run). + +### Completion stack: blink.cmp vs nvim-cmp + +**Recommendation: `blink.cmp`.** + +- `blink.cmp` (saghen/blink.cmp) is now the modern default — both LazyVim and + kickstart.nvim have switched their default completion engine to it. +- Performance: blink.cmp updates on every keystroke with ~0.5–4ms overhead vs. + nvim-cmp's default 60ms debounce and 2–50ms hitches; it ships a fast native + fuzzy matcher (Rust, with a Lua fallback for platforms without prebuilt + binaries) with typo resistance, versus nvim-cmp's fzf-style matching via + external plugin. + built-in without extra source plugins), whereas nvim-cmp needs the classic + `cmp-nvim-lsp` / `cmp-buffer` / `cmp-path` source plugins. +- nvim-cmp is still fine and stable if there's a strong reason to keep it + (huge existing source-plugin ecosystem), but for a fresh setup in 2026 + blink.cmp is the better default. + +--- + +## 2. Treesitter + +**Important/time-sensitive finding:** the `nvim-treesitter/nvim-treesitter` +repo was **archived by its maintainer on 2026-04-03** (roughly 3 months before +this research), after a public dispute over the plugin's `main` branch being +rewritten to hard-require Neovim ≥0.12 while a chunk of the user base was still +on 0.11.x. Key facts: + +- The **`master` branch is frozen** (no further updates, but functional) and + works with Neovim 0.11.x — this is what a config staying on nvim 0.11.6 + should pin to (e.g. `branch = "master"` in lazy.nvim), understanding it will + receive no further parser/query updates going forward. +- The **`main` branch is a full incompatible rewrite** requiring Neovim ≥0.12: + the old `setup({ highlight = {...}, indent = {...}, ensure_installed = {...} })` + table is gone; features like highlighting are no longer auto-enabled and must + be wired up through Neovim's core APIs directly; parser installation is now a + separate explicit function call rather than a config list. +- Neovim 0.12 (released 2026-03-29) ships **built-in treesitter support** + (parser/query loading, plus a native plugin manager `vim.pack` and native LSP + completion) directly in core, which is *why* the plugin's role shrank enough + for the maintainer to feel comfortable archiving it. +- **Implication for this project**: since the constraint is nvim 0.11.6 as a + *floor*, not a ceiling, the planning phase should explicitly decide whether + to (a) stay on 0.11.6 and pin `nvim-treesitter` to the frozen `master` branch + (parsers/queries stop advancing, but it works today with a config style + close to the current plugin ecosystem's assumptions), or (b) upgrade Neovim + to 0.12+ as part of this project and lean on built-in treesitter + + `nvim-treesitter-textobjects` (still separately maintained, main branch) for + textobjects only. Given the "no CI/test coverage, solo effort, evenings/ + weekends" constraints, (a) is lower-risk short-term; (b) is more future- + proof and avoids inheriting a now-unmaintained dependency. Recommend + flagging this explicitly as an ADR-worthy decision in Phase 3. +- Parser status for the four languages in scope (Go, Rust, Python, + TypeScript/JS) is mature and stable in either branch — these are among the + most well-maintained tree-sitter grammars in the ecosystem; no risk there. +- Use cases: syntax highlighting and incremental selection are rock-solid; + textobjects via `nvim-treesitter-textobjects` are mature; treesitter-based + **indentation** is still explicitly documented as experimental/imperfect for + some languages (worth keeping vim-polyglot's or filetype-plugin indentation + as fallback where treesitter indent misbehaves); treesitter-based + **folding** works via `foldexpr`/`foldmethod=expr` and is commonly used, but + adds some perf overhead on very large files (Konfekt/FastFold, already in the + current plugin list, works alongside it and is worth keeping regardless of + which treesitter branch is chosen). + +--- + +## 3. Fuzzy-finding + +**Recommendation: `fzf-lua`** — good fit given fzf is already installed and in +daily use, and it is now the more actively favored option community-wide, +though `telescope.nvim` remains extremely close and defensible. + +- As of LazyVim 14 (released Dec 2024), the LazyVim default fuzzy finder + changed from Telescope to fzf-lua — this is a meaningful community signal + since LazyVim's defaults strongly shape ecosystem consensus. +- Rationale: `fzf-lua` shells out to a separate process for matching/filtering + (the same fzf binary approach the user already has installed and has + muscle memory for), giving shell-like responsiveness and much better + performance on large repos/monorepos, since Telescope's picker pipeline is + mostly synchronous Lua and can bog down on large result sets. +- `telescope.nvim` (paired with `telescope-fzf-native.nvim`, a C-compiled + sorter) is still an excellent, more "native Neovim UI" experience with the + larger extension ecosystem (many community pickers/extensions are + Telescope-first) — a defensible choice if extension breadth matters more + than raw performance. +- Either choice is a clean win over the status quo of `ctrlp.vim` + + `vim-ctrlspace` + `fzf.vim` running simultaneously — all three should be + removed as part of consolidation regardless of which target is picked. + `fzf.vim` itself is the plain-Vimscript fzf wrapper and is now the + "legacy" option relative to fzf-lua/Telescope for anyone doing a Lua-based + config. +- Given the requirements' explicit note that "the user already has fzf + installed" and the appetite for minimizing new external tool dependencies, + `fzf-lua` is the pick — it reuses the exact binary already on the system + and keybinding intuitions transfer more directly than adopting Telescope's + different UI paradigm. + +--- + +## 4. DAP (debugging) + +`nvim-dap` (mfussenegger/nvim-dap) + `nvim-dap-ui` (+ `nvim-nio` as a required +dependency of dap-ui) is the only serious, actively maintained DAP client in +the Neovim ecosystem — not really a "vs" decision, this is the foundation +regardless of language. Recommend also `nvim-dap-virtual-text` for inline +variable values, and `mason-nvim-dap.nvim` to manage adapter installation +through Mason. + +Per-language adapter maturity, from most to least plug-and-play: + +| Language | Adapter | Plug-and-play? | Notes | +|---|---|---|---| +| **Go** | Delve, via `leoluz/nvim-dap-go` | **Yes — genuinely easy.** | `nvim-dap-go` wraps Delve config generation (`require('dap-go').setup()`), including per-test debugging out of the box. Delve installs cleanly via `go install` or Mason. Lowest-friction adapter of the four. | +| **Python** | `debugpy`, via `mfussenegger/nvim-dap-python` | **Yes, with Mason.** | Mason installs `debugpy` into an isolated venv (`~/.local/share/nvim/mason/packages/debugpy/venv/bin/python`); `nvim-dap-python` auto-detects project virtualenvs (`VIRTUAL_ENV`/`CONDA_PREFIX`/`venv`/`.venv` folder conventions). Setup is a couple of lines once Mason path is wired in. Recommend `mason-nvim-dap.nvim` with `ensure_installed = {"python"}` for automatic install. | +| **Rust** | CodeLLDB, via Mason, wired through **`rustaceanvim`** (not raw `nvim-dap` config) | **Mostly yes, moderate setup.** | `rust-tools.nvim` (the previous standard) was **archived Jan 2024** — its author explicitly redirects users to `mrcjkb/rustaceanvim`, a heavily modified fork. Rustaceanvim is deliberately "setup-less" and does *not* depend on `nvim-lspconfig` — it manages the rust-analyzer LSP client and DAP wiring (`:RustLsp debuggables`) itself. CodeLLDB installs cleanly via Mason. This is a bigger API-shape change vs. old rust-tools.nvim (command renames: `:RustRunnables`→`:RustLsp runnables`, etc.) so existing muscle memory / any legacy rust-tools config would need rewriting, not just swapping a dependency name. | +| **TS/JS** | vscode-js-debug, via `mxsdev/nvim-dap-vscode-js` (or Mason's `js-debug-adapter` package) | **No — genuinely fragile, flag this explicitly.** | Confirmed by multiple independent sources as the hardest of the four to set up. Historically required manually cloning `vscode-js-debug`, running `npm install --legacy-peer-deps`, `npx gulp vsDebugServerBundle`, and moving `dist/` → `out/` by hand — Mason's `js-debug-adapter` package now automates most of this, which should be preferred over the manual build. Even with Mason, the adapter's config surface (multiple debug types: `pwa-node`, `pwa-chrome`, attach vs. launch, source maps) is meaningfully more complex than the other three languages. Budget disproportionate time here relative to Go/Python, and treat "TS/JS debugging fully working" as the stretch goal of the DAP work rather than a given. | + +`nvim-dap-ui` itself is mature and stable (breakpoints, variable inspection, +call stack, REPL, watches) — no maturity concerns there; it satisfies the +"DAP-based debugger... for at least Go and Python" success metric cleanly for +those two languages. Recommend scoping DAP work as Go + Python first (both +genuinely plug-and-play), then Rust, with TS/JS as an explicit stretch/lower- +confidence item given its adapter fragility — this maps directly onto the +"DAP adapter setup per language is fragile" rabbit hole flagged in +requirements. + +--- + +## 5. Git integration + +**Recommendation: keep `vim-fugitive`, add `gitsigns.nvim`; `neogit` + +`diffview.nvim` as optional upgrades, not required.** + +- `vim-fugitive` (tpope) remains widely regarded as best-in-class for its core + job (`:G`, `:Gdiffsplit`, blame, commit/rebase workflows) — there's no strong + "native Lua fugitive replacement" the community has coalesced around the way + there is for LSP/completion/fuzzy-finding. Nothing in the research surfaced + a reason to rip it out; it's Vimscript but mature, fast, and has no + functional deficiency vs. Lua alternatives for the workflows Tyler already + uses it for. +- `gitsigns.nvim` is the near-universal complement, not a competitor — it adds + the sign-column hunk markers, inline blame, hunk stage/unstage/reset, and + hunk-navigation text objects that fugitive doesn't provide. Actively + maintained (6.7k★, commits as recent as March 2026). This should be added + regardless of what else changes — it's pure addition, not a migration risk. +- `neogit` (a Magit-alike, the direct modern replacement for the existing + `vimagit`) and `diffview.nvim` (a unified diff/merge-conflict UI, the direct + modern replacement for `Merginal`) are the natural swaps for the two + redundant git UIs currently in the plugin list. One real-world report found + in research: "Neogit is used the most by far, Gitsigns is mainly for the + aesthetic, and diffview is useful when merging" — i.e. these three + compose well together rather than compete. + `diffview.nvim`'s last commit in that search snapshot was June 2024 (vs. + gitsigns' March 2026) — worth a quick freshness check in Phase 3 before + committing, but no evidence of abandonment, just a slower cadence typical of + a feature-complete utility plugin. +- **Recommended consolidation**: drop `vimagit` and `Merginal` (redundant, + confirmed dead-weight per requirements), keep `vim-fugitive`, add + `gitsigns.nvim` unconditionally, and add `neogit` + `diffview.nvim` if Tyler + wants a more visual staging/merge experience than fugitive's buffer-based + UI — otherwise fugitive + gitsigns alone is a complete, defensible git + stack and the simpler option (fewer plugins = less to maintain, in the + spirit of the pruning goal). + +--- + +## 6. Plugin manager + +**Confirmed: `lazy.nvim` is still current best practice** for a config staying +on Neovim 0.11.x, and is already correctly bootstrapped in `.vimrc.plug` +(nothing to change there mechanically — just the misleading `.vimrc.dein` +symlink name, which the requirements already flag for cleanup/rename). + +- `lazy.nvim` remains the most mature, most widely adopted plugin manager: + async install/update, UI, lockfile (`lazy-lock.json`), conditional lazy- + loading (`event`, `ft`, `cmd`, `keys`), and the largest ecosystem + documentation/examples (LazyVim, kickstart.nvim, most current blog + tutorials assume lazy.nvim syntax). +- `pckr.nvim` (packer.nvim's spiritual successor) is a lighter alternative but + explicitly less stable/mature than lazy.nvim per community sources — no + reason to switch to it here. +- `mini.deps` is now **frozen** — its own maintainer has paused development in + favor of Neovim 0.12's new built-in `vim.pack` plugin manager. Since this + project's floor is 0.11.6 (not 0.12), `vim.pack` isn't a realistic target + yet without also deciding to bump the Neovim version (see the treesitter + 0.12 discussion above — these two decisions are linked: if the plan decides + to require nvim 0.12+, `vim.pack` becomes a live option worth a quick + look; if it stays on 0.11.6, lazy.nvim is simply the correct choice with no + serious contenders). +- No version/API-relevant breaking changes surfaced for `lazy.nvim` itself in + the 2025–2026 window — it has been the stable incumbent throughout the + ecosystem churn documented above (blink.cmp, fzf-lua, treesitter + archival), which is itself a point in its favor for a low-maintenance solo + setup. + +--- + +## 7. Current recommended versions/tags + +Nearly everything in this stack is consumed as a **rolling HEAD dependency** +via lazy.nvim (no meaningful semver tags the way e.g. npm packages have) — +this is normal for the Neovim plugin ecosystem and matches how the existing +`.vimrc.plug` already pins plugins (by repo, not by version). The concrete +pins/branches worth calling out explicitly in the plan: + +| Plugin | Pin/branch guidance | +|---|---| +| `neovim/nvim-lspconfig` | HEAD (rolling); works with both old `.setup()` style and new `vim.lsp.config`/`enable` API — no branch pin needed. | +| `saghen/blink.cmp` | HEAD; project publishes tagged releases (check latest at implementation time) — lazy.nvim users commonly pin `version = '*'` to track releases rather than main if stability matters more than bleeding-edge features. | +| `nvim-treesitter/nvim-treesitter` | **Decision-dependent**: `branch = "master"` if staying on nvim 0.11.6 (frozen, but works); `branch = "main"` only if the project also upgrades Neovim to ≥0.12.

This isn't a live conflict causing errors today only because `.vimrc` itself defines zero ``-prefixed mappings — all ~20 `` mappings live in `.vimrc.plug`/coc-vim section, and they're all written assuming space (e.g. `a`, `e`, `s` for CocList, and `f`, `a`, `rn` which resolve to space-prefixed because that's the active leader by the time they're defined). + +**Concrete risk**: any new mapping added to `.vimrc` (the "primary" file, which reads as authoritative because it's read first and has the visible `mapleader` declaration) that uses `` will silently bind to space, not comma, contradicting the file's own stated intent. A future maintainer reading `.vimrc` alone would reasonably expect comma-based bindings and be confused when they don't fire, or worse, accidentally shadow an existing space-prefixed coc/lazy binding. + +**Recommendation for planning phase**: pick space explicitly (it already wins, and is the modern-convention default per LazyVim/AstroNvim/NvChad — see below), delete the vestigial `let mapleader=","` line, and add a single authoritative comment where leader is declared, in whichever file becomes canonical after the vimscript-vs-Lua decision. + +--- + +## 1. Comparable UX patterns: how modern "IDE" Neovim setups structure interaction + +The through-line across LazyVim, AstroNvim, NvChad, and kickstart.nvim is **not** "recreate IDE panels" — it's **"surface the same information through Neovim's native primitives (floating windows, splits, buffers, quickfix) triggered by keyboard, and make discovery a keyboard action, not a persistent visual scan."** + +### 1a. Fuzzy nav — Telescope (and the fzf-lua shift) +Telescope's picker UX is a 3-pane pattern (prompt → results list → live preview) surfaced as an ephemeral floating window, not a permanent sidebar. The picker's leverage points that reduce real friction: +- **Live preview pane** — no need to open-then-check like ctrlp.vim's list-only UX; you see the file/definition before committing. +- **Composable pickers** — the same UI primitive serves file-find, live grep, LSP symbols, git status, buffers, diagnostics, etc. One interaction pattern, N data sources — this is the actual friction reduction vs. running 3 separate fuzzy-finders (ctrlp/ctrlspace/fzf.vim) with 3 different UIs and 3 sets of keybindings, which is literally the current-state problem in this repo. +- Note the ecosystem has shifted: as of LazyVim 14, **fzf-lua is now the default picker**, not Telescope, mainly for perceived speed/rendering-width complaints against Telescope (some users found Telescope's list column too narrow or laggier on large repos; fzf-lua wraps the native fzf binary for matching speed while keeping a similar preview-pane UX). Either is a legitimate "one fuzzy-finder" consolidation target — the choice is a planning-phase decision, not a UX-pattern difference; both share the prompt+list+preview interaction model this repo currently lacks as a single coherent thing. + +### 1b. Debugging — nvim-dap-ui panel layout +nvim-dap-ui's model: debug "elements" (scopes/variables, call stack, breakpoints, watches, REPL/console) are independent windows grouped into named **layouts**, dockable to any screen edge, toggled as a unit. This is the closest any of the 4 areas gets to literally cloning an IDE's persistent-panel layout — and it's also the area where the community most explicitly flags the friction: a multi-pane layout assumes mouse-driven pane-switching in IDEs, but in Neovim every pane switch is a keyboard window-nav action (`` motions), which adds real per-switch cost that doesn't exist when you just glance at an IDE's always-visible panels or click into one. +- This is why **nvim-dap-view** exists as a competing, newer approach (as of the current ecosystem): a **single-window** debug UI that time-slices between scopes/stack/watches/REPL in one buffer via tabs/toggles rather than a multi-pane split layout — explicitly trading "see everything at once" for "less window-navigation overhead." This is a genuine UX fork Tyler should be aware of during planning: nvim-dap-ui = IntelliJ-like multi-pane (familiar mental model, more nav overhead); nvim-dap-view = Neovim-native single-window (less familiar, less nav overhead). Given Tyler is actively trying to *learn* the Neovim-native workflow rather than recreate IntelliJ, nvim-dap-view's approach is worth a look, but nvim-dap-ui remains the more battle-tested/mature default with broader adapter-ecosystem documentation (relevant given the plan's own flagged DAP-maturity risk). +- Regardless of which UI, the debugging interaction model itself (breakpoint via sign-column click-equivalent keybind, step via keybinds, hover-eval via keybind or floating window) maps closely enough to IntelliJ's debugger that this is the *lowest* mental-model-mismatch area of the four — the panels differ in chrome, not in what action does what. + +### 1c. Git — gitsigns.nvim (inline) vs diffview.nvim (full-view), not either/or +The current config has three overlapping git plugins (vim-fugitive, Merginal, vimagit) mapping to a similarly overlapping IntelliJ mental model (a single "Git" panel doing everything: status, diff, blame, merge). The modern Neovim-native pattern **splits by task, not by tool**: +- **gitsigns.nvim** — inline, buffer-local awareness: sign-column markers for added/changed/deleted lines, hunk navigation, and crucially **per-line/per-hunk staging directly in the buffer you're editing** (`:Gitsigns stage_hunk`, works on a visual selection for partial-hunk staging). This is *more* granular than IntelliJ's per-file/per-hunk staging in its Commit panel — a genuine capability upgrade, not just a UI change. +- **diffview.nvim** — the full-view counterpart for when you actually need a dedicated screen: a single tabpage cycling through all changed files' diffs, and a **3-way merge-conflict view** (base/ours/theirs) for actual conflict resolution — this is the closest Neovim-native equivalent to IntelliJ's merge tool. +- **neogit** (not explicitly searched in requirements but relevant) commonly fills the "commit workflow" gap (staging UI, commit message buffer, log) that fugitive's `:Gstatus` covers today. +- The idiomatic pattern is explicitly **complementary, not competing**: gitsigns for ambient awareness + line staging (replaces the "glance at gutter" + "stage this line" IntelliJ habit), diffview for full-file-diff and merge conflicts (replaces "open the Git tool window diff"), and a commit/status UI (neogit or fugitive) for the commit workflow itself. Three tools, but each owns a distinct job — unlike the current fugitive+Merginal+vimagit trio which appears to have three tools doing overlapping subsets of the same jobs. + +### 1d. Code actions/refactors — popup-with-preview, not modal dialog +lspsaga.nvim and tiny-code-action.nvim (Telescope-integrated) and nvim-code-action-menu converge on the same pattern: a **floating popup listing available actions, navigable with j/k, with a diff/preview of the effect before committing** (Enter to execute). This is the Neovim-native equivalent of IntelliJ's Alt+Enter quick-fix popup — genuinely close in interaction shape (small popup, arrow/hjkl select, enter to apply), so this is a *low-mismatch* area once wired up, similar to debugging. The friction isn't the interaction pattern; it's that native `vim.lsp.buf.code_action()` alone (no plugin) has a plainer selection UI without the diff preview — plan should pick one of the popup-with-preview plugins rather than relying on the raw built-in prompt if "confidence doing a refactor without checking IntelliJ" is a goal. + +--- + +## 2. Mental model mismatches: what to translate, not clone + +| IntelliJ expectation | Underlying need | Neovim-native equivalent | Why it satisfies the need without cloning the UI | +|---|---|---|---| +| Always-visible project tree (left sidebar) | Spatial orientation: "where am I in the project," discoverability of files I don't remember the name of | Telescope/fzf-lua `find_files` + `oil.nvim` (edit-the-directory-as-a-buffer) rather than neo-tree/nvim-tree as a permanent drawer | Fuzzy-find covers "I know roughly what I want" (the majority case); oil.nvim covers "I want to browse/rename/move" via normal editing commands (dd to delete a file, yank/paste to copy) — no separate tree-navigation modal to learn. A permanent sidebar (neo-tree) is available as a fallback for the rarer "I need to see the whole shape of an unfamiliar codebase" case, but shouldn't be the default reflex the way IntelliJ's tree is, since it costs a fixed chunk of horizontal buffer space that Neovim's split model doesn't want to give up permanently. | +| Mouse-driven panel clicking (Debug tool window, Git tool window, Structure panel) | Fast context-switch between "what I'm editing" and "supporting info about it" | Toggleable floating windows / transient splits bound to single keypresses (`d` opens DAP UI, `gg` opens git status, `gO` opens symbol outline) that close as easily as they open | The need is fast access to supporting context, not permanent visibility of it. Transient windows keep the editing buffer maximized by default and pull in context only on demand — this is *faster* once the keybind is muscle memory, but requires giving up the "glance without pressing a key" affordance IntelliJ provides. This is the single biggest adjustment cost for an IntelliJ user and should be named explicitly rather than hidden. | +| Inline everything (inline diagnostics text at end of line by default, inline hints) | Immediate visibility of problems without extra action | Neovim's diagnostic virtual text (on by default in `vim.diagnostic`) + gitsigns inline hunk markers already match this one closely | Low mismatch — this is an area where Neovim's defaults already resemble IntelliJ's. Worth explicitly enabling/tuning (`vim.diagnostic.config({virtual_text = true})`) rather than assuming it, since some LazyVim-style configs favor virtual_lines or off-by-default to reduce clutter. | +| Structure/outline panel (persistent) | "What functions/classes exist in this file" | `gO` / Telescope `lsp_document_symbols` / trouble.nvim's symbol view as an on-demand popup | Same pattern as project tree: on-demand instead of persistent. Aider/trouble.nvim can pin it if Tyler decides he wants it more often than not. | +| Right-click → Refactor submenu | Discoverability of "what can I do to this symbol right now" | Code-action popup (see §1d) triggered by a single keybind, with which-key.nvim showing available leader-key groups on half-second hesitation | which-key.nvim specifically closes the *discoverability* gap that keyboard-only interfaces otherwise lose vs. a hoverable/clickable menu — this is probably the single highest-leverage discoverability plugin for an IntelliJ transplant and should be in scope regardless of the vimscript-vs-Lua outcome (a Lua plugin, but usable from an otherwise-vimscript config). | + +**The general translation rule surfaced by research**: Neovim-native configs don't try to make information *permanently visible* the way IntelliJ does; they make it *one keypress away and fast to dismiss*. The UX bet is that a fluent keyboard user round-trips faster than a mouse click into a sidebar, but this bet only pays off once the keybinds are internalized — which makes discoverability tooling (which-key.nvim) and keymap consistency (see §3) directly load-bearing for how fast Tyler stops missing the IntelliJ panels. + +--- + +## 3. Keymap ergonomics: leader-key conventions and organization + +### Community convention (2026 state) +Space-as-leader is now the dominant default across LazyVim, AstroNvim, NvChad, and kickstart.nvim — not a stylistic choice unique to one distro. This matters directly for Tyler's config: the *de facto* effective leader in the current setup (space, per §0) already matches the modern convention, even though it arrived there by accident/override rather than deliberate choice. + +### Common group-prefix convention under `` +Across the surveyed distros, the pattern is a mnemonic first-letter-of-category grouping, discoverable via which-key.nvim popups: + +| Prefix | Category | Typical contents | +|---|---|---| +| `c` | Code | code actions, rename, format, diagnostics-related code ops | +| `d` | Debug (DAP) | toggle breakpoint, continue, step over/into/out, toggle DAP UI | +| `g` | Git | status/hunk stage/blame/diff (gitsigns + git UI) | +| `f` or ``/`space` | Find (fuzzy) | find files, live grep, buffers, recent files | +| `s` | Search | symbols, workspace search (sometimes merged with `f`) | +| `x` | Diagnostics/trouble | project-wide diagnostics list, quickfix | +| `w` | Window | split/nav (already used in current config for vim-choosewin — a collision to resolve) | + +### Direct collision risk against the current ~50-plugin mapping surface +Concrete overlaps found by reading `.vimrc.plug` directly that the planning phase must resolve, not just "watch for": +- `w` is already bound to `vim-choosewin` (line 401) — collides with the conventional "window" group prefix. +- `f` is already bound twice inconsistently: line 193 binds it to `:Format` (a custom command) while lines 283-284 bind it to `coc-format-selected` — these are two different bindings to the same key sequence already coexisting in the file (the second simply overwrites the first at source time), which is itself a pre-existing latent bug independent of the Lua-migration question. +- `a` is bound to `coc-codeaction-selected` (lines 296-297) and also to CocList diagnostics as `a` (line 349) — since space *is* leader, `a` and `a` are the literal same key sequence, meaning one of these two bindings silently loses to source order (last-wins), not both being live as the file's structure implies. +- `ac`, `z`, `rn`, `e`, `g` (fugitive Gstatus) are all single, non-grouped leader mappings from the coc/fugitive/goyo era that don't follow a category-prefix scheme at all — a which-key-style migration needs an explicit remap table, not an incremental add, precisely because the existing bindings are flat single-letters rather than nested groups. + +**Recommendation for planning phase**: treat the leader-key layer as a full remap, not an additive one. Build an explicit before/after keybind table as a planning artifact (this is exactly the "keybinding-compat pass" the requirements doc already flags as a rabbit hole under fuzzy-finder consolidation — it should be scoped project-wide, not just for fuzzy-find, given the collisions found above already exist even before adding LSP/DAP/git-consolidation mappings on top). + +--- + +## 4. Error/edge-case UX: graceful degradation vs. silent failure + +This is the area where current tooling is weakest, and where Tyler's daily-driver experience will most concretely diverge from IntelliJ's "always just works because JetBrains bundles everything" model. + +- **LSP server not installed/attached**: Neovim's native LSP client fails *silently* by default — if `:lsp enable` can't find a root directory match or the server binary isn't on `$PATH`, the client simply never attaches, with no user-facing error unless you run `:checkhealth vim.lsp` or notice the absence of diagnostics/gd working. This is the opposite of IntelliJ, which shows an explicit "Language server not configured" banner. **Mitigation pattern**: mason.nvim + mason-lspconfig's `ensure_installed` + `automatic_installation = true` closes this gap almost entirely by making "not installed" a transient one-time install-on-first-open event rather than a standing silent gap — this should be treated as close to mandatory for the plan, not optional polish, given the requirement that LSP features "work without falling back to IntelliJ" for 4 languages. +- **DAP adapter not configured for current filetype**: no evidence of graceful native handling — attempting to start a debug session with no adapter registered for the filetype typically errors out at the point of invocation (undefined adapter key) rather than degrading gracefully. mason-nvim-dap's `ensure_installed` covers the *installation* gap the same way mason-lspconfig does for LSP, but doesn't cover the *"no launch.json-equivalent config exists for this project"* gap — nvim-dap requires either a `.vscode/launch.json`-compatible config or a Lua-defined `dap.configurations.` table per project/filetype. Given the plan's own flagged DAP fragility risk, the planning phase should budget explicit fallback UX: a friendly error via `vim.notify` when no configuration exists for the current filetype, rather than a raw Lua traceback, and sane default configs shipped for Go/Python at minimum (the two priority languages) so the "just works" bar is met without per-project setup on day one. +- **Treesitter parser missing for filetype**: confirmed via search — this is a known, currently-unresolved rough edge in the ecosystem itself, not something Tyler's config choices can fully fix. Failure is silent (no highlighting, no thrown error) rather than a clear "install this parser" prompt, and `nvim-treesitter` maintainers acknowledge this as a gap. **Mitigation available today**: `:checkhealth nvim-treesitter` surfaces missing parsers if run manually, and `auto_install = true` (evaluated per-buffer on filetype detection) closes most of the day-to-day gap the same way mason's `automatic_installation` does for LSP — but there's no equivalent to a friendly in-buffer notice today. This should be flagged in the plan as an accepted residual gap (fall back to regular vim syntax highlighting, which is what happens automatically when treesitter highlighting isn't active) rather than something to build custom tooling around. + +**Overall pattern**: the fix for all three is the same shape — **auto-install on first use (mason.nvim family) turns "missing X" from a standing silent failure into a one-time, visible, self-healing event.** This is the single highest-leverage cross-cutting UX investment across LSP/DAP/treesitter and should be called out as a planning-phase must-have rather than assumed to fall out of "just install the plugins." + +--- + +## 5. Job-to-be-done and reprioritization + +**Functional job**: get accurate code intelligence (jump-to-def, find-refs, rename, safe refactor) and a working debugger for Go/Python without opening a second application. + +**Emotional job**: confidence editing unfamiliar code without a safety net anxiety ("did that rename actually catch every reference, or did it silently miss one because coc/ale's rough edges under-deliver on the promise"), and a feeling of *control/speed* — not fighting the editor's own friction (three fuzzy-finders with unclear precedence is itself an anxiety/control problem independent of language tooling). + +**Social job**: not needing to justify the tool choice to himself or anyone else — "this just works" credibility, i.e., never having a moment mid-task where the honest answer to "why are you switching to IntelliJ" is "because Neovim doesn't do X reliably yet." + +### Does this reprioritize the 4 capability areas? + +Yes, in a specific way — **the emotional/social jobs are most threatened by the areas with the worst error/edge-case UX today, not necessarily the areas with the flashiest missing feature.** + +1. **Code intelligence & refactoring — nail first, non-negotiable.** This is the area most directly tied to the "did the tool actually work correctly" trust question (a bad rename that misses a reference is worse than no rename, because it fails silently and shows up later as a bug). Native LSP + mason auto-install is the highest-leverage, lowest-risk win here given nvim-lspconfig/native LSP maturity, and it's the prerequisite the plan's own risk section already treats as load-bearing (coc.nvim and native LSP can't cleanly coexist). +2. **Debugging — nail second, but the fragility risk (already flagged in requirements) means "good enough" should mean Go + Python solid, Rust/TS-JS acceptable-if-rough.** The DAP interaction model itself is low-mismatch (closest to IntelliJ of the four), so once an adapter is wired up correctly the UX payoff is immediate and high-confidence — but adapter setup is genuinely the most fragile plumbing of the four areas, so this is where "good enough" scoping (per the Appetite section) should flex, not where interaction-model polish should be spent. +3. **Navigation/fuzzy search — can be "good enough" faster than the other three.** Telescope or fzf-lua alone (consolidating from 3 finders to 1) delivers most of the emotional win (reduced control-anxiety from tool ambiguity) with comparatively low implementation risk and a well-worn interaction pattern. This is the one area where the *existing* redundancy itself, not a capability gap, is the primary UX problem — so the fix is mostly subtractive (delete two finders) rather than additive, which is cheap relative to the other three areas. +4. **Git integration — lowest urgency for "IDE-like" credibility, but real day-to-day friction reduction available cheaply.** IntelliJ's git tool window isn't usually the reason someone reaches for a full IDE over an editor; it's a nice-to-have consolidation (fugitive/Merginal/vimagit → gitsigns + diffview + optionally neogit) that reduces daily friction but isn't the thing standing between Tyler and closing the IntelliJ gap. Reasonable to sequence last and treat generously as "good enough" if time gets tight against the 3-6 week appetite. + +**Bottom line for planning**: prioritize (1) code intelligence with mason-backed auto-install as the trust-building foundation, (2) DAP for Go/Python specifically rather than all four languages evenly, (3) fuzzy-finder consolidation as a cheap, high-relief-value early win, and (4) git UI consolidation as valuable but appropriately last if the appetite gets squeezed — consistent with the order already implied by the requirements doc's own DAP/coc risk flags, but now with an explicit UX rationale: the areas that most threaten Tyler's *confidence* in the tool (silent failure risk) should be hardened before the areas that are merely *redundant* (fuzzy-finders, git plugins). + +--- + +## Sources + +- [AstroNvim Mappings](https://docs.astronvim.com/mappings/) +- [NvChad Mappings](https://nvchad.com/docs/config/mappings/) +- [LazyVim Keymaps](https://www.lazyvim.org/configuration/keymaps) +- [What is the preferred way to setup keymaps? — LazyVim/LazyVim Discussion #3025](https://github.com/LazyVim/LazyVim/discussions/3025) +- [Leader keys and mapping keyboard sequences — DEV Community](https://dev.to/stroiman/leader-keys-and-mapping-keyboard-sequences-3ehm) +- [nvim-dap-ui — GitHub](https://github.com/rcarriga/nvim-dap-ui) +- [nvim-dap-view: A Single-Window Debug UI for Neovim](https://zenn.dev/glmlm/articles/neovim-dap-view-20260213?locale=en) +- [nvim-dap-view — GitHub](https://github.com/igorlfs/nvim-dap-view) +- [Debugging in Neovim with nvim-dap — John Tobin](https://www.johntobin.ie/blog/debugging_in_neovim_with_nvim-dap/) +- [A Guide to Debugging Applications in Neovim — Tamerlan](https://tamerlan.dev/a-guide-to-debugging-applications-in-neovim/) +- [telescope.nvim — GitHub](https://github.com/nvim-telescope/telescope.nvim) +- [LazyVim 14, some new and breaking features — Lorenzo Bettini](https://www.lorenzobettini.it/2024/12/lazyvim-14-some-new-and-breaking-features/) +- [gitsigns.nvim — GitHub](https://github.com/lewis6991/gitsigns.nvim) +- [My Neovim Git Setup: Neogit, Gitsigns, and Diffview — Michael Bao](https://medium.com/unixification/my-neovim-git-setup-ba918d261cb6) +- [How to stage individual Git hunks without leaving Neovim using gitsigns.nvim — VimTricks](https://vimtricks.wiki/posts/gitsigns-stage-hunk) +- [Working with Git inside Vim — WhyNotHugo](https://whynothugo.nl/journal/2026/01/03/working-with-git-inside-vim/) +- [Neovim git integration — Duy NG](https://tduyng.com/blog/neovim-git-tools/) +- [nvim-lspconfig — GitHub](https://github.com/neovim/nvim-lspconfig) +- [Neovim LSP docs](https://neovim.io/doc/user/lsp/) +- [mason.nvim — GitHub](https://github.com/mason-org/mason.nvim) +- [Automating LSP Installation Without mason-lspconfig.nvim](https://zenn.dev/glmlm/articles/neovim-mason-lspconfig-20250218?locale=en) +- [Debugging in Neovim — harrisoncramer.me](https://harrisoncramer.me/debugging-in-neovim/) +- [Unable to install parsers — nvim-treesitter Issue #5570](https://github.com/nvim-treesitter/nvim-treesitter/issues/5570) +- [Failure to install parsers does not throw error — nvim-treesitter Issue #7906](https://github.com/nvim-treesitter/nvim-treesitter/issues/7906) +- [neo-tree.nvim — GitHub](https://github.com/nvim-neo-tree/neo-tree.nvim) +- [Neovim file explorers — pawelgrzybek.com](https://pawelgrzybek.com/neovim-file-explorers/) +- [Code Action — lspsaga (nvimdev)](https://nvimdev.github.io/lspsaga/codeaction/) +- [tiny-code-action.nvim — GitHub](https://github.com/rachartier/tiny-code-action.nvim) +- [nvim-code-action-menu — GitHub](https://github.com/weilbith/nvim-code-action-menu)
