3# regular expression test set
4# Lines are at least three fields, separated by one or more tabs. "" stands
5# for an empty field. First field is an RE. Second field is flags. If
6# C flag given, regcomp() is expected to fail, and the third field is the
7# error name (minus the leading REG_).
8#
9# Otherwise it is expected to succeed, and the third field is the string to
10# try matching it against. If there is no fourth field, the match is
11# expected to fail. If there is a fourth field, it is the substring that
12# the RE is expected to match. If there is a fifth field, it is a comma-
13# separated list of what the subexpressions should match, with - indicating
14# no match for that one. In both the fourth and fifth fields, a (sub)field
15# starting with @ indicates that the (sub)expression is expected to match
16# a null string followed by the stuff after the @; this provides a way to
17# test where null strings match. The character `N' in REs and strings
18# is newline, `S' is space, `T' is tab, `Z' is NUL.
19#
20# The full list of flags:
21# - placeholder, does nothing
22# b RE is a BRE, not an ERE
23# & try it as both an ERE and a BRE
24# C regcomp() error expected, third field is error name
25# i REG_ICASE
26# m ("mundane") REG_NOSPEC
27# s REG_NOSUB (not really testable)
28# n REG_NEWLINE
29# ^ REG_NOTBOL
30# $ REG_NOTEOL
31# # REG_STARTEND (see below)
32# p REG_PEND
33#
34# For REG_STARTEND, the start/end offsets are those of the substring
35# enclosed in ().
