Apparently nvim-nim works with neovim, but only if asynch mode is switched off
with
g:nvim_nim_enable_async=0
Run
Seems something in the _nimsuggest_ protocol changed and the asynch
communication function in _nvim-nim_ wasn't updated. Shouldn't be too
complicated, so if someone knows vim script: async mode would be faster..
All the non-experimental things from the help file (it's _:help nim_ , not
_:help nvim-nim_ ) seem to work, even the REPL.
The nvim-nim / YouCompleteMe / ale combo gives me all I need, with ale
autocompletion disabled
g:ale_completion_enabled=0
Run
and the more comprehensive omni-completion provided by the other two plugins.
