1regular expression test set 2Lines are at least three fields, separated by one or more tabs. "" stands 3for an empty field. First field is an RE. Second field is flags. If 4C flag given, regcomp() is expected to fail, and the third field is the 5error name (minus the leading REG_). 6 7Otherwise it is expected to succeed, and the third field is the string to 8try matching it against. If there is no fourth field, the match is 9expected to fail. If there is a fourth field, it is the substring that 10the RE is expected to match. If there is a fifth field, it is a comma- 11separated list of what the subexpressions should match, with - indicating 12no match for that one. In both the fourth and fifth fields, a (sub)field 13starting with @ indicates that the (sub)expression is expected to match 14a null string followed by the stuff after the @; this provides a way to 15test where null strings match. The character `N' in REs and strings 16is newline, `S' is space, `T' is tab, `Z' is NUL. 17 18The 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 23 i REG_ICASE 24 m ("mundane") REG_NOSPEC 25 s REG_NOSUB (not really testable) 26 n REG_NEWLINE 27 ^ REG_NOTBOL 28 $ REG_NOTEOL 29 # REG_STARTEND (see below) 30 p REG_PEND 31 32For REG_STARTEND, the start/end offsets are those of the substring 33enclosed in (). 34
