I'm trying to use the std.regex module but when I run my application I
get an exception. The exception message says:
*+? not allowed in atom
The code I have is:
import std.regex;
void main ()
{
regex(`\.(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))`, "m");
}
Well the thing is, std.regex is not quite ECMA complaint (as vaguely
stated in docs). To the best of my knowledge not a single one variant of
the forms (?:...) ... (?=...) is supported . Also see
http://d.puremagic.com/issues/show_bug.cgi?id=5169, you may try out my
patch there to support (?:...). It's a slightly outdated, but std.regex
wasn't in very active development.
I'm compiling this with DMD 2.052 on Mac OS X.
