How do I install a plugin for vim?

To expand on Karl's reply, Vim looks in a specific set of directories for its runtime files. You can see that set of directories via :set runtimepath?. In order to tell Vim to also look inside ~/.vim/vim-haml you'll want to add

set runtimepath+=$HOME/.vim/vim-haml

to your ~/.vimrc. You'll likely also want the following in your ~/.vimrc to enable all the functionality provided by vim-haml.

filetype plugin indent on
syntax on

You can refer to the 'runtimepath' and :filetype help topics in Vim for more information.


Make sure that the actual .vim file is in ~/.vim/plugin/


Those two commands will create a ~/.vim/vim-haml/ directory with the ftplugin, syntax, etc directories in it. Those directories need to be immediately in the ~/.vim directory proper or ~/.vim/vim-haml needs to be added to the list of paths that vim searches for plugins.

Edit:

I recently decided to tweak my vim config and in the process wound up writing the following rakefile. It only works on Mac/Linux, but the advantage over cp versions is that it's completely safe (symlinks don't overwrite existing files, uninstall only deletes symlinks) and easy to keep things updated.

# Easily install vim plugins from a source control checkout (e.g. Github)
#
# alias vim-install=rake -f ~/.vim/rakefile-vim-install
# vim-install
# vim-install uninstall

require 'fileutils'

  vim_dir      = File.expand_path("~/.vim")
  plugin_dir   = Dir.pwd

  if not (FileTest.exists? File.join(plugin_dir,".git") or
          FileTest.exists? File.join(plugin_dir,".svn") or
          FileTest.exists? File.join(plugin_dir,".hg"))
