appleton / Rakefile
Created December 18, 2012 09:53
A Rakefile to help managing a Jekyll site. Fill out your own ssh config in the CONFIG hash. Note that publish requires that you have ssh keys set up with your server, this doesn't work with ssh passwords (because I didn't need it).
require 'pty'
CONFIG = {
:remote => {
:host => 'my.ssh-host.com',
:user => 'my-ssh-username',
:path => 'path-to/site/root'
},
:posts => 'local/posts/directory'
}

Install Homebrew

Homebrew is MacPorts (or APT) without the suck. http://github.com/mxcl/homebrew
