ast-grep files/ignores support a case insensitive option

Introduced 2026-01-10 · score 0.93

HOW TO USE IT

When a rule should include or exclude paths regardless of case, configure its `files` or `ignores` list with a glob object and set `caseInsensitive: true`.

WHY THIS HELPS

Configure case-insensitive matching for files or ignores in an ast-grep workflow.

REQUIREMENTS AND LIMITATIONS

• Version: 0.40.5
• files: Array of glob patterns limiting which files a rule applies to; each item can be a string or an object with `glob` and `caseInsensitive`.
• ignores: Array of glob patterns excluding files from a rule; each item can be a string or an object with `glob` and `caseInsensitive`.
• glob (required): Pattern string in a glob object.
• caseInsensitive: Whether glob matching is case insensitive; defaults to `false`.
