In my last post, Subdomain accounts with Ruby on Rails explaind, I mentioned that you’d need to modify your /etc/hosts file to use custom subdomains for development/testing. Apparently, there is a much better way to handle this that I was introduced to by Nathan de Vries. Nathan suggests using a gem that I hadn’t heard of before that bares the name of Ghost (view project on github).
Ghost describes itself as…
“A gem that allows you to create, list, and modify local hostnames in 10.5 with easeā¦”—
If you’ve ever had to modify your /etc/hosts file for anything local, I highly encourage you to check out this shiny gem.
Installing Ghost
Like most gems, you can just install Ghost with the following command.
~ : sudo gem install ghost

Okay, now that Ghost is installed, let’s see what we can do with it.
Using Ghost for local domains/subdomains
Ghost is fairly straight forward. It’s essentially a friendly wrapper for dscl, which is the Directory Service command line utility
for Mac OS X. I’ve never played with that directly, but it seems that with Ghost… I shouldn’t need to. :-)
With Ghost, you can add, modify, and delete entries in the Directory Service by issuing any of the following commands. Let’s start out by running ghost to see what we have here.
I’ll let you play with it yourself as there isn’t much to it. This is a great little addition to my development environment. Thanks to Nathan for pointing it out and to Bodaniel Jeanes for creating this useful gem.
