Line breaks are randomly correct under Windows 10 and iPython.

[ubaldot]

Hi all, I am running a split window where I have the editor on top and a Windows powershell running iPython in the bottom. The problem is that when I vim-slime then the <CR> is randomly correct.
The below picture is an example of what happens by <C-c><C-c>-ing several times in a row.

As you see in In [22]: and In [23]: it worked, then it didn't work any longer. Then, it eventually worked again, then it won't work, and so on and so forth. All completely random.

I have tried to tweak ftplugin/python.slime.vim by changing line 8 with e.g. return ["%cpaste -q","\n",a:text,"--","\n"] or by adding some delay, but the random behavior is still there. As @jpalardy suggested here such a behavior sounds like a race condition but I have no idea how to solve it, nor where to start (that goes way beyond my competences).

hi @Barzi2001

Thank you for opening the separate issue for this ^

It's a new day, and I have new ideas:

• did you try reducing your config to a minimum (removing, temporarily, other plugins and settings) and see if it still behave the same?
• did you try the same config, but on linux or macos? (if you have access)

Hello!

I finally found some time to test it. I tried with the following minimum _vimrc

set encoding=utf-8
set nu
set tabstop=4 softtabstop=4
set shiftwidth=4
set expandtab
set smartindent
set nobackup
set backspace=indent,eol,start
set nocompatible              " required
set clipboard=unnamed
set laststatus=2
set statusline=%f "tail of the filename
set incsearch " for displaying while searching
set smartcase
set hidden
set noswapfile

cabbrev bterm bo terminal powershell

" --- VUNDLE PLUGIN STUFF BEGIN --------

call vundle#begin('C:/Users/yt75534/vimfiles/bundle')
Plugin 'gmarik/Vundle.vim'
Plugin 'jpalardy/vim-slime'
call vundle#end()            " required
filetype plugin indent on    " required for Vundle
" ---- VUNDLE PLUGIN STUFF END ----------

" vim-slime fix paste issues in ipython
let g:slime_python_ipython = 1
let g:slime_target = "vimterminal"
let g:slime_cell_delimiter = "# %%"
nmap <C-c><C-v> :SlimeSendCurrentLine<CR>
nmap <C-c><C-x> :SlimeSend0<CR>

and the problem persists.

Unfortunately I don't have any Linux or MacOs machine.

Any other hints are most than welcome ofc :)

UPDATE: I have updated my Anaconda environment and I am now running IPython 8.2.2. The command :SlimeSendCurrentLine seems to work perfectly now, but there is still the problem E471 Argument required when sending a code-cell, see https://github.com/jpalardy/vim-slime/issues/324
