Path Validation

import { validateIndexingPaths } from '@paparats/shared';

// Rejects absolute paths and path traversal in indexing config
const errors = validateIndexingPaths(['src', '../etc/passwd']);
// errors: ['Path traversal not allowed: ../etc/passwd']

Gitignore Filtering

import { createGitignoreFilter, filterFilesByGitignore } from '@paparats/shared';

// Per-file check
const filter = createGitignoreFilter('/path/to/repo');
if (filter('node_modules/foo.js')) {
  // file is gitignored
}

// Bulk filter
const included = filterFilesByGitignore('/path/to/repo', allFiles);

Exclude Patterns

import {
  normalizeExcludePatterns,
  getDefaultExcludeForLanguages,
  LANGUAGE_EXCLUDE_DEFAULTS,
  COMMON_EXCLUDE,
  DEFAULT_EXCLUDE_BARE,
} from '@paparats/shared';

// Bare dir names become glob patterns: 'node_modules' -> '**/node_modules/**'
const patterns = normalizeExcludePatterns(['node_modules', 'dist']);

// Get default excludes for specific languages
const excludes = getDefaultExcludeForLanguages(['typescript', 'python']);
