; ; ; this file contains a script of tests to run through regress.exe ; ; comments start with a semicolon and proceed to the end of the line ; ; changes to regular expression compile flags start with a "-" as the first ; non-whitespace character and consist of a list of the printable names ; of the flags, for example "match_default" ; ; Other lines contain a test to perform using the current flag status ; the first token contains the expression to compile, the second the string ; to match it against. If the second string is "!" then the expression should ; not compile, that is the first string is an invalid regular expression. ; This is then followed by a list of integers that specify what should match, ; each pair represents the starting and ending positions of a subexpression ; starting with the zeroth subexpression (the whole match). ; A value of -1 indicates that the subexpression should not take part in the ; match at all, if the first value is -1 then no part of the expression should ; match the string. ; ; Tests taken from BOOST testsuite and adapted to glibc regex. ; ; Boost Software License - Version 1.0 - August 17th, 2003 ; ; Permission is hereby granted, free of charge, to any person or organization ; obtaining a copy of the software and accompanying documentation covered by ; this license (the "Software") to use, reproduce, display, distribute, ; execute, and transmit the Software, and to prepare derivative works of the ; Software, and to permit third-parties to whom the Software is furnished to ; do so, all subject to the following: ; ; The copyright notices in the Software and this entire statement, including ; the above license grant, this restriction and the following disclaimer, ; must be included in all copies of the Software, in whole or in part, and ; all derivative works of the Software, unless such copies or derivative ; works are solely in the form of machine-executable object code generated by ; a source language processor. ; ; THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR ; IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, ; FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT.
