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