Looks like your version is very old, because the change-log in RxParser class>>#b:whatsNewInThisRelease says: VERSION 1.1a (May 2001) 1. Support for keeping track of multiple subexpressions. 2. Dot (.) matches anything but NUL character, as it should per POSIX spec. 3. Some bug fixes. Pharo contains the latest version available: VERSION 1.3.1 (September 2008) Additionally the version in Pharo includes an uncountable number of bug-fixes related to regular expressions that would cause infinite recursion, repeated matches, skipped matches, invalid empty matches, misaligned replacements, etc. Unfortunately these changes were not back-ported into the official VisualWorks version, as I never heard back from Vassily.

Is there a way to allow the regex '.' (dot) to match line break characters: 'hello regex' matchesRegex: '.*regex' Â Â "true" 'hello regex' matchesRegex: '.*regex' Â Â "false"
In my image the second expression returns true as well.
In fact the '.' (dot) matches anything but the null character (see
#syntaxAny).
Thanks - I shouldn't make assumptions - it matches in Pharo but not in Gemstone - I assumed the implementations would be identical. As you say the culprit is RxMatcher>>#syntaxAny In Pharo: RxMatcher>>#syntaxAny ^RxmPredicate new predicate: [:char | char asInteger ~= 0]
In Gemstone: RxMatcher>>#syntaxAny ^RxmPredicate new predicate: [:char | (Cr = char or: [Lf = char]) not] Nick _______________________________________________ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project
