Making GTK+ development in VIM more fun:

Calling devhelp

To call the API documentation browser devhelp on the identifier under the cursor you can use:

"call devhelp:
autocmd Filetype c nmap <silent> <C-K> :! devhelp -s "<cword>" &<CR><CR>

in you ~/.vimrc. The above example uses CTRL-K since manual pages are shown with SHIFT-K.

Syntax highlighting

The Debian package vim-syntax-gtk offers syntax highlighting for GTK+, Glib, Pango, DBus-glib and much more. To enable it run:

vim-addons -w install gtk-syntax
ln -s /usr/share/doc/vim-syntax-gtk/examples/c.vim ~/.vim/after/syntax/
