Indentation is lost (ipython)

[kprimice]

Hi,

Thank you for this plugin, I am already an heavy Nvim-R user. Wanted to try this one for python.

My problem is when I try to send this code:

It fails because of the indentation:

I tried to use an external terminal (with tmux) or the nvim buffer. But it fails everytime.

Thank you for you help

Perhaps this is a problem with 'expandtab'. Did you set this option in your vimrc? Anyway, some people have reported incompatibility between vimcmdline and ipython.

[kprimice]

Yes, here are the options I use:

au BufNewFile,BufRead *.py \ set tabstop=4 | \ set softtabstop=4 | \ set shiftwidth=4 | \ set textwidth=79 | \ set expandtab | \ set autoindent | \ set fileformat=unix

I just checked: Indeed it is an ipython related bug.

Thanks for the feedback. I am going to add a warning when cmdline_app["python"] value is "ipython".

[jalvesaq]

The solution for the indentation issue is:

let g:cmdline_app = {"python": "ipython --no-autoindent"}

But I noted other issues:

• ipython starts in a state similar to Vim's Normal mode, and I have to press either i or a to go to insert mode before sending lines from Neovim to ipython.
• Neovim terminal does not auto scroll when lines are sent.

@jalvesaq , when I set this cmdline_app, I got

@kprimice is the author of #27

well, even if I delete the definition of cmdline_app, there is no complain from vim side, but still, the indentation is wrong when I leader+space a python function

I am using python-mode/pythonmode and vim-scripts/indentpython.vim
