Parallelize golangci-lint

[jay-babu]

Unsure if this is possible but i am using the below. it would be nice if we could take advantage of --allow-parallel-runners to parallelize the runs. I have about 5 modules and it takes a very long time if I edit all of them.

# yaml-language-server: $schema=https://json.schemastore.org/pre-commit-config.json
repos:
  - repo: https://github.com/tekwizely/pre-commit-golang
    rev: v1.0.0-rc.4
    hooks:
      # GolangCI-Lint: pick ONE of these, depending on how you want it to scale
      - id: golangci-lint-repo-mod   # monorepo: run per module that has staged changes (sweet spot)
        args:
          - --fix
      # - id: golangci-lint           # file-based (often not what you want for lint)
      # - id: golangci-lint-mod       # module mode
      # - id: golangci-lint-repo-pkg  # even narrower: per package that changed

Hi @jay-babu and thanks for taking the time to submit an issue.

Tell me, what happens when you try to add the --allow-parallel-runners option t the list of args: ?

The args should be passed directly to golangci-lint

@TekWizely i can pass that in but that just means i can run golangci-lint in parallel myself. The gap is that the pre-commit still is invoking golangci-lint in serial for each mod. The ask is to run the linter in parallel as well fully which should speed up the time as it runs in parallel

@jay-babu Thanks for taking time to clarify - I see now we need a way to send all files (or a configurable number) to the command.

I've got a test branch with support for --hook:batch-size=N ( where 0 => all files) - I'll have a PR up shortly and hopefully you'll be available to test.

@jay-babu lemme know if you have a chance to test the changes on #49
