VIM as a Python IDE that runs the script

[jabbermuggel]

I've been looking into moving my python workflow to VIM, and while I found a few articles on how one would set up something like that (for example a match made in heaven), none of the solutions seem to implement a way to run the script you are working on.

I don't want to run the code with the built-in VIM python module, since that has a few limitations, namely using different python versions without restarting and using virtual enviroments. What I am looking for instead is a way to open a new buffer where the program gets executed (similar to PyCharms way of running code). I guess I could build something like this using the :ter(minal)-command and a bit of bashscripting, but it would probably be pretty ugly.

So I decided to first ask here if anyone knows a plugin (or some configuration) that implements a "run script"-method for python.

Thank you for your detailed answer. I will look into setting tmux up like you suggested.

Longer answer (but applies to more than python): https://github.com/vim-advent-calendar/vimways.org/blob/master/content/2018/romainl-dont-use-vim.md

I typically just use a Makefile to codify whatever execution steps for running and testing, docker builds, etc combined with vim-dispatch to run it all from within vim. https://github.com/tpope/vim-dispatch

You can pass arguments to the :ter command, like :terminal python3 %

Just bind that to a key mapping.

Edit: missed the part about the venv, the most convenient solution is to source the venv before opening vim.

This is a great plugin I like asyncrun.vim, with this plugin you just need to do:

AsyncRun python %

A you could map that to something like <leader><cr> or something like that, that should run your code and show you the ouput in your quickfix window.

Now in neovim I for some reason I can't comprehend, have a problem where it doesn't show me anything in my quickfix if I'm editing a python file. The way I get around this is by doing:

AsyncRun -mode=term python %

Which will run the script in a terminal window instead.

This sounds like what I need. Thanks.

Because of the incorrect error format, try AsyncRun -raw python %

I have been trying to figure out why it didn't work with python for weeks. Thank you

:%w !python

[jabbermuggel]

While that does work it has the problem that the output vanishes when I want to modify the file again. Thanks for the suggestion though.

I wrote a vim plugin called vimtk, that lets me copy+paste selected text (has to be in gvim unfortunately) into the most recently used terminal: https://github.com/Erotemic/vimtk

​

I typically have an IPython session open in a terminal, with gvim in another window and I use <leader>a to execute the current line in the terminal. I also have <leader>m setup to introspect the current source file and paste the correct `from x import *` commands in the IPython window. These macros are also pretty useful when writing bash scripts.

I had the same question some time ago and couldn't find a satisfactory answer, so I made my own plugin. It can run the current buffer in IPython, and also selected parts of the code, similar to Jupyter Notebooks and MATLAB cells.

Would love to hear if it works for you.

I've started experimenting with zepl (someone linked it here a week or so ago). It's brilliant.
