I've just pushed a branch with alternative implementation of vim bindings
here: https://github.com/yi-editor/yi/tree/vim2
Things that are different in the new implementation
---------------------------------------------------
- It has tests.
- It is split into modules.
- It uses explicit VimState instead of using parser approach using
KeymapM. My brain couldn't keep track of all the edge cases otherwise,
sorry.
- Slightly different subset of vim features is implemented.
- It doesn't have a new implmentation of Ex, so it just shamelessly
imports exMode and exEval from Vim.hs and it appears to work.
How to try it in the editor
---------------------------
``yi --as=vim2``
How to run and add tests
------------------------
Invoke ``make`` in yi/src/tests. It works only after building yi
itself, because it reuses some files from build directory. Yes, it's ugly.
If someone has a better way to do it, I'd be happy to know.
There's a short readme about tests here: src/tests/vimtests/README.rst
