Discussion: custom_app branch

Feel free to close this/move to a more appropriate section, but I figured this would be the best place to discuss the commit to allow different REPLs.

It works for haskell, but (i)python support is broken. I suspect you will have to use paste mode (%cpaste), and you may want to see how vim-slime does it.

They have good handling for python but don't open the repl for you.

Note: I almost never use any REPL other than R. That is, I almost never use vimcmdline. That said, I installed and tested ipython in a Neovim buffer, and noted that it has Normal and Insert modes, like Vim.
I noted this because when sending %cpaste ipython actually only "receives" ste, as Vim would do if it was in Normal mode.

If I send to ipython a line containing only the letter a, it enters Insert mode and, then, I can send commands normally. If it is not in Insert mode, nothing works, including sending

%cpaste -q
The_Python_line
--

So, it seems that users have to make sure that ipython is in Insert mode before sending commands to it.

I use it in emacs mode actually, since nested modes are a pain. In emacs mode, I still run into issues.

[jalvesaq]

Is https://github.com/ivanov/vim-ipython a better alternative than vimcmdline for ipython? I did not install it.

[1o0ko]

@jalvesaq vim-ipython is a little cumbersome. It requires you to open ipython kernel/console beforehand.

[alok]

I've not used vim-ipython, so I can't really speak to that.

The incompatibility between vimcmdline and ipython was discussed at #18, and there is no solution for it (so, I'm closing this issue).
