VimLab

VimLab replicates MATLAB's support for code sections in Vim. It uses tmux to maintain a MATLAB session from within vim.

Requirements

VimLab relies on tmux and screen.vim which are used to set up and communicate with a MATLAB session. It expects the matlab command to be on your $PATH. Code analysis, similar to that offered by MATLAB's editor, is provided by the excellent Syntastic plugin. If mlint is on your path as well, Syntastic will automatically analyze your MATLAB code when it's saved.

tmux

VimLab requires vim to run inside a tmux session. Linux users may find a tmux package is provided by their favorite distribution. For OS X users, I recommend installing tmux using homebrew.

For a well written introduction to tmux, please take a look at the book "tmux: Productive Mouse-Free Development" by Brian P. Hogan.

screen.vim

VimLab uses Screen.vim to manage a MATLAB session within tmux.

Syntastic (Optional)

Install Syntastic if you wish to have your MATLAB code automatically analyzed when it is saved.

Installation

I recommend installing VimLab using Vundle. Add the following lines to your .vimrc file:

Bundle "ervandew/screen"
Bundle "dajero/VimLab"
"Optional, if you desire automatic code analysis
Bundle "scrooloose/syntastic"

Next, either quit and relaunch vim or source .vimrc from within your current vim session. Finally, issue the :BundleInstall command to vim to install VimLab and its dependencies.

Usage

VimLab automatically creates a few key mappings when you enter a MATLAB buffer. These mappings are prefixed by your leader, which defauls to \. If you set your mapleader to a different character, please mentally substitute the backslash by the mapleader of your choice.

• \mm starts matlab
• \ms sends the current section to MATLAB
• \md open the documentation for the current word
• \mh show help for the current word
• \mv show the variable the cursor is on
• gn go to the next section
• gN go to the previous section

VimLab also provides two commands to quickly open the documentation or help for a function:

• :MATDoc my-function opens the documentation for my-function
• :MATHelp my-function shows help for my-function

Configuration

By default, VimLab splits your tmux window horizontally to create a pane for MATLAB. If instead, you prefer the panes to be arranged vertically, set the varible g:matlab_vimlab_vertical to 1, e.g. add the following line to your .vimrc:

let g:matlab_vimlab_vertical=1
