| 7 * Date: 22 June 2001 | |
| 8 * | |
| 9 * SUMMARY: Regression test for Bugzilla bug 87231: | |
| 10 * "Regular expression /(A)?(A.*)/ picks 'A' twice" | |
| 11 * | |
| 12 * See http://bugzilla.mozilla.org/show_bug.cgi?id=87231 | |
| 13 * Key case: | |
| 14 * | |
| 15 * pattern = /^(A)?(A.*)$/; | |
| 16 * string = 'A'; | |
| 17 * expectedmatch = Array('A', '', 'A'); | |
| 18 * | |
| 19 * | |
| 20 * We expect the 1st subexpression (A)? NOT to consume the single 'A'. | |
| 21 * Recall that "?" means "match 0 or 1 times". Here, it should NOT do | |
| 22 * greedy matching: it should match 0 times instead of 1. This allows | |
| 23 * the 2nd subexpression to make the only match it can: the single 'A'. | |
| 24 * Such "altruism" is the only way there can be a successful global match... | |
