1# regular expression test set 2# $FreeBSD$ 3# Lines are at least three fields, separated by one or more tabs. "" stands 4# for an empty field. First field is an RE. Second field is flags. If 5# C flag given, regcomp() is expected to fail, and the third field is the 6# error name (minus the leading REG_). 7# 8# Otherwise it is expected to succeed, and the third field is the string to 9# try matching it against. If there is no fourth field, the match is 10# expected to fail. If there is a fourth field, it is the substring that 11# the RE is expected to match. If there is a fifth field, it is a comma- 12# separated list of what the subexpressions should match, with - indicating 13# no match for that one. In both the fourth and fifth fields, a (sub)field 14# starting with @ indicates that the (sub)expression is expected to match 15# a null string followed by the stuff after the @; this provides a way to 16# test where null strings match. The character `N' in REs and strings 17# is newline, `S' is space, `T' is tab, `Z' is NUL. 18# 19# The full list of flags: 20# - placeholder, does nothing 21# b RE is a BRE, not an ERE 22# & try it as both an ERE and a BRE 23# C regcomp() error expected, third field is error name 24# i REG_ICASE 25# m ("mundane") REG_NOSPEC 26# s REG_NOSUB (not really testable) 27# n REG_NEWLINE 28# ^ REG_NOTBOL 29# $ REG_NOTEOL 30# # REG_STARTEND (see below) 31# p REG_PEND 32# 33# For REG_STARTEND, the start/end offsets are those of the substring 34# enclosed in (). 35 36# basics 37a & a a 38abc & abc abc 39abc|de - abc abc 40a|b|c - abc a 41 42# parentheses and perversions thereof 43a(b)c - abc abc 44a\(b\)c b abc abc 45a( C EPAREN 46a( b a( a( 47a\( - a( a( 48a\( bC EPAREN 49a\(b bC EPAREN 50a(b C EPAREN 51a(b b a(b a(b 52# gag me with a right parenthesis -- 1003.2 goofed here (my fault, partly) 53a) - a) a) 54) - ) ) 55# end gagging (in a just world, those *should* give EPAREN) 56a) b a) a) 57a\) bC EPAREN 58\) bC EPAREN 59a()b - ab ab 60a\(\)b b ab ab 61 62# anchoring and REG_NEWLINE 63^abc$ & abc abc 64a^b - a^b 65a^b b a^b a^b 66a$b - a$b 67a$b b a$b a$b 68^ & abc @abc 69$ & abc @ 70^$ & "" @ 71$^ - "" @ 72\($\)\(^\) b "" @ 73# stop retching, those are legitimate (although disgusting) 74^^ - "" @ 75$$ - "" @ 76b$ & abNc 77b$ &n abNc b 78^b$ & aNbNc 79^b$ &n aNbNc b 80^$ &n aNNb @Nb 81^$ n abc 82^$ n abcN @ 83$^ n aNNb @Nb 84\($\)\(^\) bn aNNb @Nb 85^^ n^ aNNb @Nb 86$$ n aNNb @NN 87^a ^ a 88a$ $ a 89^a ^n aNb 90^b ^n aNb b 91a$ $n bNa 92b$ $n bNa b 93a*(^b$)c* - b b 94a*\(^b$\)c* b b b 95 96# certain syntax errors and non-errors 97| C EMPTY 98| b | | 99* C BADRPT 100* b * * 101+ C BADRPT 102?
