I'm working on porting a simple text note taking application from

stuck on how
to implement search.
In the old implementation, I got the text data, got the curser
offset and did
the search with regex.
Looking through the gtk docs, I see there are GtkTextView and
GtkSourceView
widgets with corresponding Buffer objects. TextBuffer lists
insensitive search as a
"possible future" feature, while SourceBuffer implements insensitive
search,
but still lists regex as "possible future".
I don't need most of what SourceView does, I'm only dealing with
plain text.
2 questions.
#1 if I have:
GtkTextMark *mark;
GtkTextBuffer *bf;
data = gtk_text_buffer_get_text (bf, &start, &end, FALSE);
mark = gtk_text_buffer_get_insert (bf);
is there a simple way to convert mark into an offset into data?
I realize that won't work right with non-ascii characters.
#2 is there yet another set of gtk objects that will give me regex
and case
insensitive searches using an official api?
Glib has regular expressions and you can always transform an iter/mark
to a string position.
Take a look at this demo:
http://github.com/potyl/gtk2-sourceview2/blob/master/examples/perl-editor.pl#L261
It was my attempt to mimic nedit (a great motif editor) in gtk2. I
have there support for detach with regexpes event if gtkdourceview
doest provide it.
