luaをインストール

luaを有効にしたVimを設置するためlua関連ライブラリをインストールする。
lua-develはyumで設置する。
luajitを設置するとluaをより高速で使える。gitリポジトリを取得してtarballで設置する。

クックブックを生成

  % bin/knife cookbook create lua -o site-cookbooks

レシピを作成

  package 'lua-devel' do
    action :install
  end

  src_filepath = "#{Chef::Config['file_cache_path']}/luajit"

  git "#{src_filepath}" do
    repository node['lua']['luajit_url']
    user 'root'
    group 'root'
  end

  bash 'install_luajit' do

    EOH

Vim 7.4をインストール

クックブックの生成

Berkshelfファイルにクックブックを追加する。

  % vi Berkshelf

  ... snip ...
  cookbook 'vim'

cookbooksの配下に保持する。

  bin/berks vendor cookbooks

Attributes

cookbooks/vim/attributes/default.rb
- install_methodがpackageの場合、yumで設置される。
- install_methodがsourceの場合、ソースコンパイルで設置される。

  default['vim']['install_method'] = 'package'

cookbooks/vim/attributes/source.rb
- CentOS 6以上ではlua-develに依存される。

  ... snip ...

  default['vim']['source']['configuration'] = "--without-x --enable-pythoninterp --enable-rubyinterp --enable-tclinterp --enable-luainterp --enable-perlinterp --enable-cscope  --with-features=huge --prefix=#{default['vim']['source']['prefix']}"

                                                 )

  ... snip ...

lua-devel、luajitの設置した後、Vimをソースコンパイルで設置するとluaを有効にしたVimが設置されるわけだ。
