Compile Vim with Python support on OSX with Homebrew


Mahdi asked me today how I compiled Vim with +Python on OSX and I couldn't remember the exact commands, so I am writing this blog post so I will remember in the future and because someone else might find this useful.

Compiling Vim with +Python or +Ruby is required if you want to run any plugins that have peices that are written in those languages. The usual way around this on OSX is to just install MacVim and use that. However, if you really want to use terminal Vim, you are out of luck on OSX.

So this is where Homebrew comes in, we can use Homebrew to compile vim from a custom formula. The only requirements to do this are Mercurial and Homebrew.

You can install Mercurial by using either easy_install or pip:

#install mercurial
sudo easy_install mercurial
#or
sudo pip install mercurial

You can follow the directions on the Homebrew Github Wiki to install homebrew.

Now you can Install this Homebrew formula which has been modified slightly to my tastes to install Vim.

To install this formula you can just use this command, or fork the Gist and modify the formula as you see fit(that's what I did) to install your flavor of Vim.

brew install https://raw.github.com/gist/2051422/0cfce544a4ab86318221c4d7213306a7b7ec7b3d/vim.rb

By default the Vim compiled with this script is compiled with +python and +ruby, if you want support for other interpreters you can pass those parameters to the script with:

--enable-interp=NAME,...", "lua, mzscheme, perl, python, python3, tcl and/or ruby"

You can also specify vim be compiled with features(the scripts, default is normal) To see what the features do, you can see this rather ugly table

--with-features=TYPE", "tiny, small, normal, big or huge"

Now that you have vim installed with your interpreters and features compiled, go ahead and check the version:

vim --version

and you should see that it is the updated version.

If you don't see that it is the updated version, it means your /usr/local/bin isn't on your path, or if it is on your path it comes after usr/bin.

So how do you fix this?

Option 1: Update your path:

In your .zshrc (you are using Zsh right?) or .bashrc update your path.

#this
export PATH=/usr/bin:/usr/sbin
#to this
export PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin

Option 2: Move your old Vim and symlink the new one

You can move the Vim that comes with OSX and Symlink the one brew installed

sudo mv /usr/bin/vim /usr/bin/oldvim
ln -s /usr/local/bin/vim /usr/bin/vim

One of those should solve your problem.

Protip:

You may notice that your terminal Vim does not support backspace in Insert mode with the settings I have setup in the brew formula.

If this is something you want, you can stick this line in your .vimrc:

set backspace=indent,eol,start

I think that should be it. If you have any questions leave it in the comments or ask me on twitter.
