| description | Instructions for running prek, the Carbon pre-submit/style/lint checker, that *MUST* be run before submitting an change. |
prek is the Carbon pre-submit, style, and lint checker. Running it is
mandatory before submitting any changes.
To run prek on all files:
prek run -a
To validate a specific list of files:
prek run --files <files>
If you are working in a Jujutsu workspace, running prek directly will fail
because it expects a standard Git repository structure. Instead, use the helper
script:
./scripts/jj_prek.sh
This script runs prek on all files that have changed between trunk and your
current Jujutsu @ change.
[!TIP] If
prekfails with an error about resolving dependencies or security policy, you may be running in a restricted environment where the special-purposegpkgtool is required. Prefix the command withgpkg, for example:gpkg prek run -aorgpkg ./scripts/jj_prek.sh.
