pre-commit

The pre-commit git-hooks toolchain for OpenCharly images — the orchestrator plus the linters its hooks invoke.

The pre-commit candy installs three tools, each as a real executable at a known path:

Compose the layer by adding this repo to a box's candy: composition (a candy: node carrying base: with a nested candy: list):

my-dev-box:
  candy:
    base: fedora
    candy:
      - '@github.com/opencharly/layer-pre-commit:v2026.243.0409'

Then, inside the built image (or on a dev host):

pre-commit --version      # the orchestrator
taplo --version           # TOML linter/formatter
markdownlint --version    # Markdown linter

The candy's plan: asserts each binary exists at its fixed path and reports its version with a clean exit — the hook toolchain is directly verifiable.

• charly.yml — the pre-commit: candy entity (the require: list, the package: entry, the cargo install taplo-cli step, and the check: assertions) and the embedded pre-commit-skill: skill entity.
• pixi.toml / pixi.lock — the conda-forge environment providing pre-commit.
• package.json — pins markdownlint-cli for the global npm install.
• .github/workflows/tag-on-merge.yml — CalVer tag + CHANGELOG/ on merge.
• README.md — this user overview.
