vim-slime

Grab some text and "send" it to a GNU Screen / tmux session.

VIM ---(text)---> screen / tmux

Presumably, your screen contains something interesting like, say, a Clojure REPL. But if it can receive typed text, it can receive it from vim-slime.

The reason you're doing this? Because you want the benefits of a REPL and the benefits of using Vim (familiar environment, syntax highlighting, persistence ...).

Read the blog post.

Installation

I recommend installing pathogen.vim, and then simply copy and paste:

cd ~/.vim/bundle
git clone git://github.com/jpalardy/vim-slime.git

If you like it the hard way, copy plugin/slime.vim from this repo into ~/.vim/plugin.

Configuration (GNU Screen)

By default, GNU Screen is assumed, you don't have to do anything. If you want to be explicit, you can add this line to your .vimrc:

let g:slime_target = "screen"

Because Screen doesn't accept input from STDIN, a file is used to pipe data between Vim and Screen. By default this file is set to $HOME/.slime_paste. The name of the file used can be configured through a variable:

let g:slime_paste_file = "$HOME/.slime_paste"

This file is not erased by the plugin and will always contain the last thing you sent over. If this is a problem, I recommend you switch to tmux.

When you invoke vim-slime for the first time (see below), you will be prompted for more configuration.

screen session name

This is what you put in the -S flag, or one of the line of "screen -ls".

screen window name

This is the window number or name, zero-based.

Configuration (tmux)

Tmux is not the default, to use it you will have to add this line to your .vimrc:

let g:slime_target = "tmux"

When you invoke vim-slime for the first time (see below), you will be prompted for more configuration.

tmux socket name

This is what you put in the -L flag, it will be "default" if you didn't put anything.

tmux target pane

":" means current window, current pane (a reasonable default)
":i" means the ith window, current pane
":i.j" means the ith window, jth pane

By default STDIN is used to pass the text to tmux. If you experience issues with this you may be able to work around them by configuring slime to use a file instead:

let g:slime_paste_file = "$HOME/.slime_paste"

This file is not erased by the plugin and will always contain the last thing you sent over. If this behavior is undesired one alternative is to use a temporary file:

let g:slime_paste_file = tempname()

Key Bindings

By default, the current paragraph will be sent. This is equivalent to typing vip. If you (visually) select text, that will be sent over:

C-c, C-c  --- the same as slime

You can just hold Ctrl and double-tap c.

There will be a few questions, as to where you want to send your text, and the answers will be remembered. If you need to reconfigure:

C-c, v    --- mnemonic: "variables"
