📝 Walkthrough

Walkthrough

The skipInstall() function in simple-git-hooks.js was enhanced to detect CI environments using the is-ci package. When CI is detected, the function now logs an informational message and returns early, preventing git hook installation in continuous integration contexts.

Changes

Cohort / File(s)	Summary
CI Environment Detection simple-git-hooks.js	Added CI detection logic to skipInstall() function using require('is-ci'). When running in CI, the function logs [INFO] CI detected, skipping installing hook. and returns early before existing default behavior.

Poem

🐰 In CI pipelines where bots toil and run,
No need for hooks when the tests are done,
We detect the machine, skip with a smile,
And log the truth: "No hooks here, but style!"

465-468: Add tests for the new CI branch in skipInstall().

Current tests cover SKIP_INSTALL_SIMPLE_GIT_HOOKS, but not CI detection. Please add at least one case asserting CI causes skipInstall() to return true (and skip hook setup in postinstall/CLI flows).

This is a breaking change, not everyone wants this. And you can easily set SKIP_INSTALL_SIMPLE_GIT_HOOKS=1 env on CI.

agree, then it could be shipped as v3 🙂
