示例1: buildMatcher

/*
 * Builds a regexp that matches the given `pieces`
 *
 * It returns:
 * - the `regexp` to be used to match the generated code,
 * - the `groups` which maps `$...$` identifier to their position in the regexp matches.
 */
function buildMatcher(pieces: (string | RegExp)[]): {regexp: RegExp, groups: Map<string, number>} {
  const results: string[] = [];
  let first = true;
  let group = 0;

  const groups = new Map<string, number>();
  for (const piece of pieces) {
    if (!first)
      results.push(`\\s${typeof piece === 'string' && IDENT_LIKE.test(piece) ? '+' : '*'}`);
    first = false;
    if (typeof piece === 'string') {
      if (MATCHING_IDENT.test(piece)) {
        const matchGroup = groups.get(piece);
        if (!matchGroup) {
          results.push('(' + IDENTIFIER.source + ')');
          const newGroup = ++group;
          groups.set(piece, newGroup);
