1/-- This set of tests is not Perl-compatible. It checks on special features 2 of PCRE's API, error diagnostics, and the compiled code of some patterns. 3 It also checks the non-Perl syntax the PCRE supports (Python, .NET, 4 Oniguruma). Finally, there are some tests where PCRE and Perl differ, 5 either because PCRE can't be compatible, or there is a possible Perl 6 bug. 7 8 NOTE: This is a non-UTF set of tests. When UTF support is needed, use 9 test 5, and if Unicode Property Support is needed, use test 7. --/ 10 11< forbid 8W 12 13/(a)b|/I 14Capturing subpattern count = 1 15May match empty string 16No options 17No first char 18No need char 19 20/abc/I 21Capturing subpattern count = 0 22No options 23First char = 'a' 24Need char = 'c' 25 abc 26 0: abc 27 defabc 28 0: abc 29 \Aabc 30 0: abc 31 *** Failers 32No match 33 \Adefabc 34No match 35 ABC 36No match 37 38/^abc/I 39Capturing subpattern count = 0 40Options: anchored 41No first char 42No need char 43 abc 44 0: abc 45 \Aabc 46 0: abc 47 *** Failers 48No match 49 defabc 50No match 51 \Adefabc 52No match 53 54/a+bc/I 55Capturing subpattern count = 0 56No options 57First char = 'a' 58Need char = 'c' 59 60/a*bc/I 61Capturing subpattern count = 0 62No options 63No first char 64Need char = 'c' 65 66/a{3}bc/I 67Capturing subpattern count = 0 68No options 69First char = 'a' 70Need char = 'c' 71 72/(abc|a+z)/I 73Capturing subpattern count = 1 74No options 75First char = 'a' 76No need char 77 78/^abc$/I 79Capturing subpattern count = 0 80Options: anchored 81No first char 82No need char 83 abc 84 0: abc 85 *** Failers 86No match 87 def\nabc 88No match 89 90/ab\idef/X 91Failed: unrecognized character follows \ at offset 3 92 93/(?X)ab\idef/X 94Failed: unrecognized character follows \ at offset 7 95 96/x{5,4}/ 97Failed: numbers out of order in {} quantifier at offset 5 98 99/z{65536}/ 100Failed: number too big in {} quantifier at offset 7 101 102/[abcd/ 103Failed: missing terminating ] for character class at offset 5 104 105/(?X)[\B]/ 106Failed: invalid escape sequence in character class at offset 6 107 108/(?X)[\R]/ 109Failed: invalid escape sequence in character class at offset 6 110 111/(?X)[\X]/ 112Failed: invalid escape sequence in character class at offset 6 113 114/[\B]/BZ 115------------------------------------------------------------------ 116 Bra 117 B 118 Ket 119 End 120------------------------------------------------------------------ 121 122/[\R]/BZ 123------------------------------------------------------------------ 124 Bra 125 R 126 Ket 127 End 128------------------------------------------------------------------ 129 130/[\X]/BZ 131------------------------------------------------------------------ 132 Bra 133 X 134 Ket 135 End 136------------------------------------------------------------------ 137 138/[z-a]/ 139Failed: range out of order in character class at offset 3 140 141/^*/ 142Failed: nothing to repeat at offset 1 143 144/(abc/ 145Failed: missing ) at offset 4 146 147/(?# abc/ 148Failed: missing ) after comment at offset 7 149 150/(?z)abc/ 151Failed: unrecognized character after (? or (?- at offset 2 152 153/.*b/I 154Capturing subpattern count = 0 155No options 156First char at start or follows newline 157Need char = 'b' 158 159/.*?b/I 160Capturing subpattern count = 0 161No options 162First char at start or follows newline 163Need char = 'b' 164 165/cat|dog|elephant/I 166Capturing subpattern count = 0 167No options 168No first char 169No need char 170 this sentence eventually mentions a cat 171 0: cat 172 this sentences rambles on and on for a while and then reaches elephant 173 0: elephant 174 175/cat|dog|elephant/IS 176Capturing subpattern count = 0 177No options 178No first char 179No need char 180Subject length lower bound = 3 181Starting chars: c d e 182 this sentence eventually mentions a cat 183 0: cat 184 this sentences rambles on and on for a while and then reaches elephant 185 0: elephant 186 187/cat|dog|elephant/IiS 188Capturing subpattern count = 0 189Options: caseless 190No first char 191No need char 192Subject length lower bound = 3 193Starting chars: C D E c d e 194 this sentence eventually mentions a CAT cat 195 0: CAT 196 this sentences rambles on and on for a while to elephant ElePhant 197 0: elephant 198 199/a|[bcd]/IS 200Capturing subpattern count = 0 201No options 202No first char 203No need char 204Subject length lower bound = 1 205Starting chars: a b c d 206 207/(a|[^\dZ])/IS 208Capturing subpattern count = 1 209No options 210No first char 211No need char 212Subject length lower bound = 1 213Starting chars: \x00 \x01 \x02 \x03 \x04 \x05 \x06 \x07 \x08 \x09 \x0a 214 \x0b \x0c \x0d \x0e \x0f \x10 \x11 \x12 \x13 \x14 \x15 \x16 \x17 \x18 \x19 215 \x1a \x1b \x1c \x1d \x1e \x1f \x20 !
