"string" is actually an alias for "immutable(char)[]" (and
similarly for
the other string types), so its contents are not modifiable, though
its
length can be adjusted and contents appended. If you need to be
able to
modify the characters, just use char[] instead. You can then use the
.idup property to get a string afterward.
I'm converted temp_ to CharT[] as suggested, but the conversion back
to a string is failing:
_charset = temp_.idup;
main.d(76): Error: cannot implicitly convert expression (_adDupT((&
D58TypeInfo_AT4main14__T5regexTAyaZ18basic_string_token5CharT6__initZ),cast
(string)temp_)) of type immutable(CharT)[] to string
Would it work for you if the regex template took the character type
instead of the string type?
The relevant lines:
template regex(CharT)
{
// ...
alias CharT[] StringT;
StringT _charset;
enum size_t MAX_CHARS = CharT.max + 1;
// ...
_charset = squeeze(_charset.idup).dup;
And then, in main:
regex!(char).basic_string_token token_;

IMHO it's more general if the regexp took the string type as a
parameter. This is because later that is easier generalizable to
accepting a range that's different from an array.
My dream: to have a compile-time-generated regex engine that can operate
on any input stream.
