vim-screenpaste

Vim plugin that lets you copy and paste to a different GNU screen window.

screenpaste-demo

Works only within a GNU screen session. (Detects $STY)
For interactive development, similar to Jupyter Notebook. You can paste your code on a bash shell or an ipython interpreter.
Detects vim/neovim and ipython running, and paste within an appropriate paste mode.

Note that it:

Uses many system calls. Tested mainly on Ubuntu and Windows WSL.

Features

[num]-: Paste line or selection to Screen window <num>. If [num] is not specified, paste to window 0. Detect if Vim or iPython is running on the window, and paste accordingly.
\-: Paste to window named -console.
[num]_, \_: Same as - but does not detect program nor add newline at the end.
<C-_>: Copy to Screen paste buffer. You can paste it with <C-a> ] anywhere.

Installation

Use your favourite plugin manager. I use vim-plug.
TL; DR: just add the following lines to your .vimrc. It will install vim-plug and this plugin all together.

" Install vim-plug if not found
let data_dir = has('nvim') ? stdpath('data') . '/site' : '~/.vim'
if empty(glob(data_dir . '/autoload/plug.vim'))
  silent execute '!curl -fLo '.data_dir.'/autoload/plug.vim --create-dirs  https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

" Run PlugInstall if there are missing plugins
autocmd VimEnter * if len(filter(values(g:plugs), '!isdirectory(v:val.dir)'))
  \| PlugInstall --sync | source $MYVIMRC
\| endif
