line-pattern

Requires every line in the block to match a regex. Catches typos in lists whose items have a strict format — slugs, semver strings, env-var names.

Syntax

Attribute	Value	Default
line-pattern	regex	—

Example

slugs = [
    # <block line-pattern="^[a-z0-9-]+$">
    "valid-slug",
    "another-one",
    # </block>
]

Adding "Not A Slug" to that list fails the run.

Notes

• Matching is against the trimmed line, so leading indentation does not need to be in the regex.
• Blank lines are skipped.
• The pattern is used as a search, not an implicit full-line match — anchor it with ^ and $ if you want the whole line to conform, as in the example above.
• Only the first non-matching line in a block is reported; fix it and re-run to see the next.
• An invalid regex is a hard error, not a violation.
