Extending completions in ftplugin

[mg979]

Since g:mucomplete#user_mappings is only read once, I was thinking of a buffer variable that is read to extend completions, if these are defined in a ftplugin.

In this example I'm using BufEnter because I think it runs after FileType event, and it wouldn't trigger too often. In the extend function I'm not using error or you'd get an error every time, keep could be used but I think it's not so important.

augroup MUcompleteUpdateCompletions
  au!
  au BufEnter * if exists('b:mucomplete_user_mappings')
        \     |   call extend(s:compl_mappings, b:mucomplete_user_mappings)
        \     | endif
augroup END

I don't think that a buffer variable is ideal for the situation you describe. I have added a new function to the current master, which can be used as follows (e.g., in your after/ftplugin/python.vim):

call mucomplete#add_user_mapping("python_exception", "\<c-r>=python#exceptions()\<cr>")

Note that you cannot override existing methods this way.

Edit: fix typo.
