I've looked at the GtkSourceView 3 Reference Manual, and I've googled for a while, but I cannot find any mention of why gtk_source_iter_forward_search was dropped from gtksourceview or what should be used instead.
I've also looked at the features link at the gtksourceview website where it lists as a feature: Caseless UTF-8 compliant search.
I've looked at the gedit source ver 3.2.6 (since I know they use gtksourceview), but they seem to be using gedit_document_search_forward, which I'm guessing comes from some other library. So my question is, what happened to the search capabilities in gtksourceview? Is there another library that provides similar functionality to gtk_source_iter_forward_search, or is it now done another way within gtksourceview?
I originally wrote my editor in gtksourceview-2.0, now I am rewriting it using gtksourceview-3.0, and I have an established search forward function based on the gtk_source_iter_forward_search function.
Thanks.
Always browse the source if you want to know these things. I found in this commit that GtkSourceIter was removed because the functionality was moved to GtkTextIter.
