This action checks if PR titles conform to the Contribution Guidelines โ๏ธ
Consistent title names help maintainers organise their projects better ๐
Shows if the author has reaaaaally read the Contribution Guidelines :P
Create a config file .github/pr-title-checker-config.json
like this one below:
{
"LABEL": {
"name": "title needs formatting",
"color": "EEEEEE"
},
"CHECKS": {
"prefixes": ["fix: ", "feat: "],
"regexp": "docs\\(v[0-9]\\): ",
"regexpFlags": "i",
"ignoreLabels" : ["dont-check-PRs-with-this-label", "meta"]
},
"MESSAGES": {
"success": "All OK",
"failure": "Failing CI test",
"notice": ""
}
}
You can pass in one of prefixes
or regexp
or even both based on your use case. regexpFlags
and ignoreLables
are optional fields.
If LABEL.name
is set to ""
, adding or removing labels will be skipped. The CI test will continue to pass/fail accordingly.
If none of the checks pass, a label will be added to that pull request.
If at least one of them passes, the label will be removed.
This action causes CI tests to fail by default. However, if you do not want CI tests failing just because of this action, simply set alwaysPassCI
as true in the CHECKS field. An invalid config file will always cause the action to fail.
Adding label names to the optional ignoreLabels
field will forfeit any checks for PRs with those labels.
The config file is always pulled from the action's context, i.e., the branch from which the pull request is made.
See other ways to specify config file.

This is useful if a repo containing the config file is pulled in a previous step using, for e.g., actions/checkout. See #36
pull_request_target
event trigger should be used (notpull_request
) in order to support checking PRs from forks. This was added inv1.3.2
. See #8.pass_on_octokit_error
is an optional input which defaults to false. Setting it to true will prevent the CI from failing when an octokit error occurs. This is useful when the environment this action is run in is not consistent. For e.g, it could be a missing GITHUB_TOKEN. Thanks to @bennycode for pointing this out.
