name: Issue area labeler
|
|
|
|
# Adds area labels to new/edited issues based on keyword regexes in
|
|
# .github/issue-labeler.yml. Additive only (addLabels never removes): it
|
|
# never touches a label a maintainer set by hand. Base bug/enhancement
|
|
# labels already come from the issue forms.
|
|
#
|
|
# Implemented with first-party actions/github-script (not a third-party
|
|
# labeler action) so every pattern is compiled as a JavaScript RegExp with
|
|
# the `i` flag applied centrally — inline `(?i)` groups are PCRE-only and
|
|
# threw `SyntaxError: Invalid group` on every issue (#764). A pattern that
|
|
# fails to compile now fails the run loudly instead of silently no-oping.
