This also means that users don't have to +re-implement these commonly used rules themselves as [user-defined](user_defined_rules.md) rules. + +To enable certain contrib rules, you can use the `--contrib` flag. +```sh +$ cat examples/commit-message-1 | gitlint --contrib contrib-title-conventional-commits,CC1 +1: CC1 Body does not contain a 'Signed-off-by' line +1: CL1 Title does not start with one of fix, feat, chore, docs, style, refactor, perf, test: "WIP: This is the title of a commit message." + +# These are the default violations +1: T3 Title has trailing punctuation (.): "WIP: This is the title of a commit message." +1: T5 Title contains the word 'WIP' (case-insensitive): "WIP: This is the title of a commit message." +2: B4 Second line is not empty: "The second line should typically be empty" +3: B1 Line exceeds max length (123>80): "Lines typically need to have a max length, meaning that they can't exceed a preset number of characters, usually 80 or 120." +``` + +Same thing using a `.gitlint` file: + +```ini +[general] +# You HAVE to add the rule here to enable it, only configuring (such as below) +# does NOT enable it. +contrib=contrib-title-conventional-commits,CC1 + + +[contrib-title-conventional-commits] +# Specify allowed commit types.
