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)
