So i have been trying to install this plugin:

http://halfhourhacks.blogspot.com/2008/03/gedit-regular-expression-plugin.html

in gedit 3.2.1 but there seem to be some issues. I have modified the .plugin file and now it shows up in the list of plugins. But when i try to select the plugin from the list, gedit closes. So i noticed that the plugin import modules from GTK+2 so i tried changing them to the GTK+3 equivalents. Also a lot of the built in plugins code look slightly different than this plugin. After making changes to init.py, when i click on the plugin from the list of plugins that is in the list, a error icon shows up next to the plugin name and it gets greyed out. Has anyone been able to port this plugin?
