Failure to start ipython in vim terminal

[konradzdeb]

I'm using the following configuration in my .vimrc to enable vim-slime and vim-ipython-cell receiving and executing code received from the Python scripts.

.vimrc

" -- IPython Cell / slime config
let g:slime_python_ipython = 1
" map verbose cell execution to ce
nnoremap <LocalLeader>ce :IPythonCellExecuteCellVerbose<CR>
" Start vim slime in vertical terminal
let g:slime_target = "vimterminal"
let g:slime_vimterminal_config = {"term_finish": "close"}
let g:slime_vimterminal_config = { "vertical": 1 }
let g:slime_vimterminal_cmd = "ipython"

My intention is to enable execution of cells in a vertical vim terminal. Working with the script below:

sample_script.py

# %% Define Variable

A = '12 9 61 5 14'.split(' ')
A = map(int, A)

I'm attempting to execute the Define Variable cell. Vim launches terminal correctly, and it seems that attempts to execute the ipython command. However, ipython fails to start with the following error message:

Question

How to ensure that ipython REPL starts properly in vim terminal when called via vim-slime?

hi @konradzdeb

Thanks for reporting this ^

I'll have a look tonight and report back.

hi @konradzdeb

I re-read this and nothing jumps at me. Can you try another target, preferably tmux? Let's try to isolate what works and what doesn't.

If you have a "docker recipe", I could also try to reproduce on side.

Let me know

[konradzdeb]

Hi, thanks for your responsiveness. There is no problem with passing commands to tmux but I've started ipython manually, what would be the equivalent to setup to launch tmux session automatically with ipython running? So far I've

" -- IPython Cell
let g:slime_python_ipython = 1
" map verbose cell execution to ce
nnoremap <LocalLeader>ce :IPythonCellExecuteCellVerbose<CR>
" Start vim slime in vertical terminal
" let g:slime_target = "vimterminal"
" let g:slime_vimterminal_config = {"term_finish": "close"}
" let g:slime_vimterminal_config = { "vertical": 1 }
" let g:slime_vimterminal_cmd = "/Users/konrad/.pyenv/shims/ipython"

let g:slime_target = "tmux"

Hi @konradzdeb

I've been thinking about this problem, and, for now, I'm using this script. What it does:

• creates a file with a generated name, _vimrepl.EXT
• opens that file in vim
• splits tmux vertically
• starts a REPL in the split

for example:

> vimrepl js -c node

opens _vimrepl.js with node in the split. Have a look at the script and use it if it's helpful.

HI @jpalardy ,

The vimrepl script works as expected when run inside tmux.
