Author: johan

New Revision: 280
URL: http://svn.gnome.org/viewvc/gobject-introspection?rev=280&view=rev

Log:
2008-05-31  Johan Dahlin  <jdahlin async com br>

    * giscanner/xmlwriter.py:
    Improve error reporting when trying to quote None.
    * giscanner/girparser.py:
    Do not print warnings when including more complete .gir files
    * giscanner/girwriter.py:
    Do not require a name for parameters, add a todo for singletons
    * giscanner/glibtransformer.py:
    Refactor the way structs are done, add a couple of hacks to allow
    us to get further.
    * giscanner/transformer.py:
    Add enough hacks so cairo, atk and pango.gir can be parsed properly
    * gobject-introspection-1.0.pc.in:
    Export girdir, so we can access gobject-2.0.gir from outside
