Installation

Pathogen

The recommended installation method is via Pathogen. Then simply execute

cd ~/.vim/bundle
git clone https://github.com/mxw/vim-xhp.git

Manual Installation

If you have no ~/.vim/after directory, you can download a tarball or zip from GitHub and copy the contents to ~/.vim.

If you have existing ~/.vim/after files, copy the syntax and indent files directly into their respective destinations. If you have existing after syntax or indent files for PHP, you'll probably want to do something like

mkdir -p ~/.vim/after/syntax/php
cp path/to/vim-xhp/after/syntax/php.vim ~/.vim/after/syntax/php/xhp.vim
mkdir -p ~/.vim/after/indent/php
cp path/to/vim-xhp/after/indent/php.vim ~/.vim/after/indent/php/xhp.vim
