Vim langmap breaks plugin (bépo)

Question

I am using a bépo keymap (http://bepo.fr) and seeking the perfect vim mapping.

So far I used a long list of noremap, but for many binding (for exemple, the motion aw or Ctrl+r), the first keystroke is well remaped but not the others, I reckon it's the expected behaviour, but then this is not what I need.

Ideally I would have my keyboard totally remaped in a higher level (before the map commands) except when typing text (in insertion mode and when typing a substitution for exemple). What I'm looking for seems to be langmap, but I have problems using it.

I added this langmap to my .vimrc, It seems perfect but it broke some of my plugins. SuperTab now insert <Plug>SuperTabForward when pressing Tab in insertion mode, I have t<SNR>24_SelectCompletion(1) when pressing enter.

Does someone know how to fix this langmap issue or a better way to remap my keyboard?

Answer 1

This is a known bug, that has been discussed before. I have made a patch (see the thread starting here) and hopefully Bram will include this change soon.

Update 11/05/2014
This has been fixed by patch 7.4.502. Use the langnoremap option to fix this.
