use of backreferences in Glib::Regex::replace

["Andrea Benazzo" <andy qitty net>]

Hi *,

I'm trying to use the Glib::Regex::replace method to move parts of a string like in "aaaaa bbbbb" into "bbbbb aaaaaa".
I'm using a regex like "([a-z]+) ([a-z]+)" and the replacement "\2 \1", but I can't manage to correctly use the backreferences.

Here is a snipped of my code:


Glib::RefPtr<Glib::Regex> reg=Glib::Regex::create("([a-z]+) ([a-z]+)");
output_string=reg->replace(input_string,0,"--\2--\1--",Glib::REGEX_MATCH_NEWLINE_ANY);


then the output string is="--
----"



do you have any hint?


Thanks.



ps: the documentation of the Glib::Regex class should be checked because the descriptions related to method Glib::Regex::replace (among others) is broken due to the heavy use of backslashes in original documentation of Glib.
