Job is dead due to NotADirectoryError: [Errnp 20]

[Millani]

Hi, I have been successfully working with NCM2 + Python for a while, and today needed to also get autocompletion for R. I just installed ncm-R by pasting the relevant installing code in my .vimrc. The plugin seems to have been properly installed in my .vim/plugged folder.

However, every time that I open any .r file, I get an error. See the output of my :messages:

No matching autocommand

In case it helps, I am using gVim 8.1 (same happens with Vim 8.1) on Ubuntu 18.04.

Thanks for the bug report.

I'll have to check on that a bit later when I have more time, but it's possible that it has to do with the https://github.com/roxma/vim-hug-neovim-rpc Vim support, which is still experimental. ncm-R works for me with vim8 though.

If you had time to test your setup with neovim, that would be helpful as well.

Hi @gaalcaras thanks for the quick follow-up. I had a few minutes to try it in Neovim and got the same problem, with basically same error messages:

[ncmR] Can't find completion files. Please load the R packages you need (e.g. "base" or "utils").

Thanks for trying it out with nvim.

Then it's a problem with accessing the completion files generated by Nvim-R. Have you started Nvim-R first? Can you check if the directory g:rplugin_compldir exists on your system? If so, please paste the output of ls of that directory.

[Millani]

Hi @gaalcaras thanks for your feedback. Ok, I had installed Nvim-R but never initialized a terminal with it, for instance with <localleader>rf, because I have been using Slime to send R code directly to Vim 8.1 terminals. Therefore, I did not have any g:rplugin_compldir directory created - hence the error message I was getting. Upon opening a Nvim-R terminal, that was solved and then the autocompletion started working as expected.

Last question. The folder that I get g:rplugin_compldir pointing to is home/millani/.chace/Nvim-R/. So, because it's in cache folder, does this mean that eventually it will stop working again until I explicitly open a R terminal with Nvim-R? If so, that is annoying and hence my question: couldn't one simply set g:rplugin_compldir to a manually created folder that has all contents from home/millani/.chace/Nvim-R/ to make this permanent?

Thanks!

A cache directory is not necessarily a temporary directory, so unless you manually remove the cache directory you should be fine. But you can still set up a custom completion directory if you'd like, see :help R_compldir.

Also, keep in mind that ncm-R works hand in hand with Nvim-R, so you could miss on some completion features if you use something else to interact with the R console.
