Really I thought '+' => '' means '+100' is equal to '100' or vice versa :) By: Mushfeq Khan RE: Dice example or regexp engine error [ reply ]   2007-06-30 22:18 Sergey, Thanks for pointing that out. The bug is actually not in the regular expression engine, it's in the documentation. :) That line should actually read: '+' => '\+', (and the source for this code is actually correct, see it at http://viewvc.rubyforge.mmmultiworks.com/cgi/viewvc.cgi/website/src/dice_roller/dice_lexer_specification.rb?root=dhaka&view=markup), but for some reason my html generator is causing it to be munged. I'll try to get it fixed as soon as possible, since it must be causing a lot of people a lot of confusion. By the way, if you do the following you can get all the sources, for both the gem and the website: svn checkout svn://rubyforge.org/var/svn/dhaka Mushfeq. By: Sergey Molodtsov Dice example or regexp engine error [ reply ]   2007-06-30 20:08 I have got an error caused by string '+' => '' in DiceLexerSpecification when I tried to compile lexer into Ruby. IMO it's a bug of regexp engine. I suppose it does not eat empty strings, i.e. '', at all; I have not found "" element in regex_grammar file.
