matchesIgnorePatterns function

bool matchesIgnorePatterns({ required String relativePath, required List<String> patterns, })

Returns whether relativePath is excluded by patterns.

relativePath must be relative to the scan root (reference or target). patterns use gitignore-compatible syntax, including ! negation.

Implementation

bool matchesIgnorePatterns({
  required String relativePath,
  required List<String> patterns,
}) {
  if (patterns.isEmpty) {
    return false;
  }

  final normalizedPath = normalizeIgnoreRelativePath(relativePath);
  var ignored = false;

  for (final pattern in patterns) {
    if (pattern.startsWith('!')) {
      if (matchesIgnorePattern(
        relativePath: normalizedPath,
        pattern: pattern.substring(1),
      )) {
        ignored = false;
      }
    } else if (matchesIgnorePattern(
      relativePath: normalizedPath,
      pattern: pattern,
    )) {
      ignored = true;
    }
  }

  return ignored;
}
