[Gtk2hs-users] GtkSourceView, first patches

[Duncan C. <du...@co...>]

All,

Here are the first bits of my GtkSourceView bindings. I couldn't figure
out how to get cvs diff to show new files that aren't in the repository
so the new files are attached in a tar.bz2. The changes to existing
files are attached as a cvs diff -U2.

Some explanation: 

All the new bindings files are in gtk2hs/gtk/sourceview/
They are not complete but are enough to get a simple demo working.
(gtk2hs/demo/sourceview/).

Various build hacks are required to get the demo to build. I have
included them in a seperate attached patch as they are rather ugly. Some
simple changes are required to gtk/multiline/TextBuffer.chs to allow the
functions it defines to be used on SourceBuffer (GtkSourceBuffer
inherits from GtkTextBuffer). This amounts to changing "TextBuffer -> "
to "TextBufferClass tb => tb ->" and casting using toTextBuffer. To make
the demo build I just changed the two such functions that it used. I'll
submit a patch to change all of them in due course.

So the changes that are in the attached patch are mainly to the
configure.in, other configure/build files. The only other change is to
add the new classes in gtk/typehier/hierarchy.list

What remains to be done is:
      * to get it to build as a separate package, and to do so without
        needing the current hacks.
      * To complete the bindings by adding the missing functions and the
        other objects/classes & structs.
      * to extend the demo app to get greater coverage of the API.
      * I've still not figured out how to convert [String] <-> GSList of
        strings.
