1 | # regular expression test set |
| 2 | # Lines are at least three fields, separated by one or more tabs. "" stands | |
| 3 | # for an empty field. First field is an RE. Second field is flags. If | |
| 4 | # C flag given, regcomp() is expected to fail, and the third field is the | |
| 5 | # error name (minus the leading REG_). | |
| 6 | # | |
| 7 | # Otherwise it is expected to succeed, and the third field is the string to | |
| 8 | # try matching it against. If there is no fourth field, the match is | |
| 9 | # expected to fail. If there is a fourth field, it is the substring that | |
| 10 | # the RE is expected to match. If there is a fifth field, it is a comma- | |
| 11 | # separated list of what the subexpressions should match, with - indicating | |
| 12 | # no match for that one. In both the fourth and fifth fields, a (sub)field | |
| 13 | # starting with @ indicates that the (sub)expression is expected to match | |
| 14 | # a null string followed by the stuff after the @; this provides a way to | |
| 15 | # test where null strings match. The character `N' in REs and strings | |
| 16 | # is newline, `S' is space, `T' is tab, `Z' is NUL. | |
| 17 | # | |
| 18 | # The full list of flags: | |
| 19 | # - placeholder, does nothing | |
| 20 | # b RE is a BRE, not an ERE | |
| 21 | # & try it as both an ERE and a BRE | |
| 22 | # C regcomp() error expected, third field is error name | |
