Key bindings about nvim-r HOT 8 CLOSED

I did not know about them. Thanks for the news! How can I see R running inside a Vim's buffer through slimv? I already installed slimv. What should I do now? I did not find instructions on how to install swank-r for Vim.

You can change all Nvim-R key bindings. Please, see :h Nvim-R-key-bindings.

Hi, thanks for the quick answer!

Well, I'm using this ~/.vim/after/syntax/r.vim:

let g:swank_port=4009
let g:slimv_swank_cmd='!nohup setsid /usr/bin/xterm -e R -e "X11(); while (1) { swank() }" > /tmp/swankr.txt 2>&1 &'

let g:slimv_simple_compl=1

setlocal iskeyword-=*
setlocal iskeyword-==
setlocal iskeyword-=[
setlocal iskeyword-=]

:nnoremap <f2> "ryap"r:call SlimvEvalRegion()<CR>
:nnoremap <f3> "syap"s:call SlimvEvalSelection("t", getreg("r"))<CR>

along with the R parts from https://github.com/phmarek/swankr.

Yes, I know that I can change all key bindings (and have done so for too many plugins already) - but having some way to get them compatible out-of-the-box via a single :let g:...= would be nice, too!

Today, I had time to look at swank. It is interesting to see R running in a Vim's buffer, but it has some bugs, e.g., when I pressed the backspace key there was an error. Neovim terminal is definitively better.

Regarding your question, there is no way of changing the key bindings other than mapping the <Plug>s one by one because the default key bindings are hard-coded in R/common_global.vim and ftplugin/*.vim. And I cannot change the default key bindings because they are in use for years now.

I am closing the issue. If someone has a better solution than mapping the <Plug>s, please, either reopen the issue or make a pull request.

Sorry for not responding earlier; I'd have hoped for a 2nd set of bindings in that script, that are used via simply changing a single configuration parameter - like :set g:R_use_slimv_compatible_keys=1...

from nvim-r.

I could accept a pull request for this if the other software were highly popular. I guess this is not the case of slimv. So, in my opinion your demand is very specific, and in this case I think it would be more appropriate if someone could write a Vim script to be listed as part of R_source. Please, see:

:h R_source

from nvim-r.

@phmarek , are you aware that you can map to your own liking in your own config? You don't need to use the defaults?

ftplugin/r.vim

map <buffer> ,eb <Plug>RSendFile

etc...

from nvim-r.

@mdlerch, yes, I know.

But I guess there'll be quite a few people using slimv already - and why should each of them configure the keys on her own?
