Bug #51123 for JE: Unescaped dashes in character classes are rejected

Thu Nov 05 04:45:43 2009 andreas [...] one.com - Ticket created

JE fails to parse character classes containing unescaped dashes that don't specify a range: var re = /[\w-\d]/; As I read ECMA-262 this is syntax is perfectly fine (NonemptyClassRanges => ClassAtom => -). In perl 5, IE6, and Firefox it works as expected. Those are the only ones I've tested. I found this bug when I ran the entire ExtJS library through JE's parser. Everything else parsed fine! Best regards, Papandreou

Unescaped dashes in character classes are rejected

Whoops, sorry for the missing subject, and obviously this isn't fixed in 0.041. This bug tracking system always confuses the hell out of me!

Section 15.10.2.15 of ECMAScript does not allow [\w-\s]: If A does not contain exactly one character or B does not contain exactly one character then throw a SyntaxError exception. However, Nitro also supports this, so I think it’s worthwhile to add it. This I’ve done in version 0.042, which will be released some time today.
