Problems with Autocompletion

[kyanh <kyanh o2 pl>]

Hi!

I am currentlly maintaining winefish latex editor ( http://winefish.sf.net/ )

= 0 =

I wrote successfully the completion support for program. But currently, only 
the latex commands which are started by a back slash (\) are recognized. For 
example,

\testa
\testb

(latex commands often start with \)

See [1] for details.

Now i want to support completion for words. The problem is that it is hard to 
recognized words, cause a word may be started by a boundary characters 
(newline, tab, back slash,....).

How can I do? I thought of some solutions, but i donnot know the best 
quality :)


Thanks for replies.

{/* get text at doc's iterator */
 GtkTextMark * imark;
 GtkTextIter itstart, iter, maxsearch;
 imark = gtk_text_buffer_get_insert( doc->buffer );
 gtk_text_buffer_get_iter_at_mark( doc->buffer, &iter, imark );
 itstart = iter;
 maxsearch = iter;
 gtk_text_iter_backward_chars( &maxsearch, 50 );

 /* find backward the \\ ; the result may contains newline character :( */   
 if ( gtk_text_iter_backward_find_char( &itstart, ( GtkTextCharPredicate )
   find_char, GINT_TO_POINTER( "\\" ), &maxsearch ) ) {
  maxsearch = iter; /* re-use maxsearch */
  buf = gtk_text_buffer_get_text( doc->buffer, &itstart, &maxsearch, FALSE );
 }
 }

/* buf will be used for completion -- using GCompletion structure */
