🐛 commitlint plugin not enabled by all relevant dependencies

Prerequisites

• I'm using the latest version
• I've read the relevant documentation
• I've searched for existing issues
• I've checked the list of known issues
• I've read the issue reproduction guide

Reproduction url

https://stackblitz.com/edit/github-hfa3yv?file=commitlint.config.ts

Note that it flags commitlint.config.ts as an unused file, and the 3 dependencies as unused.
All these issues are fixed by manually enabling the plugin with commitlint: true in the Knip config.

Description of the issue

Currently, the commitlint plugin only uses @commitlint/cli to be enabled

It should also probably also use the commitlint package itself

In my project, I don't use @commitlint/cli, but I do use commitlint (in a git hook and on CI with the commitlint orb), and I have these in my devDependencies

  "devDependencies": {
    "@commitlint/config-conventional": "19.5.0",
    "@commitlint/types": "19.5.0",
    "commitlint": "19.5.0",
  },

That doesn't like an actual reproduction? Any chance you could fix that up?

I updated my repro link. I think it should work now 🙏

Thinking about this more, it isn't clear to me whether the current behavior is broken or not.

The commitlint plugin correctly handles all dependencies and config files when it is enabled (which I currently do manually in my project). The question is whether @commitlint/cli should be the only dependency that causes it to be enabled. I don't think @commitlint/config-conventional or @commitlint/types should cause the dependency to be enabled - those are secondary packages that only make sense in your project if you are using commtlint.

However, maybe it does make sense to detect the commitlint package itself, as long as its used in some script. In my project (not included in the minimal repo link above), I use commitlint in:

• .husky/commit-msg with the contents commitlint --edit "$1"
• In my CircleCI config (.circleci/config.yml), with the commitlint/lint job (from this orb)

Perhaps that level of detection is getting too smart, and it's better to have projects manually enable the commitlint plugin in their Knip config
