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
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#
32# For REG_STARTEND, the start/end offsets are those of the substring
33# enclosed in ().
