RE: [Flashcoders] Found an AS3 RegExp Bug.
Hi Isaac,
/[^\\]'/
Is interpreted as match any character that isn't a back slash and that is
followed by a single quote
So in "alert('foo');" the first character that is not \ and is followed by '
is the first (
so the total match is (' which is replaced by \' which results in:
alert\'foo');
The same applies to your second replace statement, where the match is o'
(again first non back slash followed by single quote) which is replaced by
\' and now results in alert\'fo\');
- Benny
P.S. within a character class there is no need to escape the \ because in
there it has no special meaning, so you can write /[^\]'/

RE: [Flashcoders] Found an AS3 RegExp Bug.
The results you get are as expected.
To get the output you desire try:
var code:String = "alert('foo');";
code = code.replace(/'/g,"\\'");
trace(code);

Let me correct a paste mistake there:
THE FOLLOWING CODE:
var pattern:RegExp = /[^\\]'/;
var code:String = "alert('foo');";
code = code.replace(pattern, "\\'");
code = code.replace(pattern, "\\'");
traces: "alert\'fo\');"
Should it not trace: "alert(\'foo\');" instead?
