TF‑Lang (v0.6) — True Functions, Algebra & Deterministic Pipelines

Live site: https://LexLattice.github.io/tf-lang/

TF-Lang v0.6 — What’s new

• Minimal L0 kernel (Transform, Publish, Subscribe, Keypair) with effect derivation and human-readable tf check --summary.
• Macro growth across state/process/policy/time/auth, including deterministic YAML parsing for multi-line macros.
• Runtime tooling: tf runtime exec --trace, adapter skeleton emission, and expanded law diagnostics.
• Instance planning: registry v2, table rendering, and per-node explanations via tf plan --format table --explain.
• Docs & onboarding: consolidated quickstarts, contributor guide, and annotated example scenarios.

Entry points: v0.6 review, Top issues roll-up, Track proposals, Examples index.

Quickstart

Requirements

• Node.js 18+
• pnpm 8+

Verify your toolchain and install workspace dependencies:

pnpm -v && node -v
pnpm -w install --frozen-lockfile

Explore the fast-track pipeline

# Discover available subcommands
pnpm tf --help

# Expand the L2 pipeline into its canonical L0 DAG
pnpm tf expand examples/v0.6/pipelines/auto.fnol.fasttrack.v1.l2.yaml --out out/0.6/tmp/fnol.l0.json

# Summarize effects, policy coverage, capabilities, and law status
pnpm tf check out/0.6/tmp/fnol.l0.json --summary

# Plan runtime instances and see which registry rule fired
pnpm tf plan out/0.6/tmp/fnol.l0.json --format table --explain

# Inspect the runtime trace with determinism markers
pnpm tf runtime exec out/0.6/tmp/fnol.l0.json --trace

Run focused checks

# Type inference with adapter suggestions
pnpm tf typecheck out/0.6/tmp/fnol.l0.json

# Emit adapter scaffolding for mismatched ports
pnpm tf typecheck out/0.6/tmp/fnol.l0.json --emit-adapters out/0.6/tmp/adapters

# Execute the example suite
bash tasks/run-examples.sh

Additional track-specific recipes live under docs/ and are linked from the v0.6 documentation index.
