A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

# This is a reasonably well-behaved helper for command-line scripts needing to ask a simple yes/no question.
# It optionally accepts a prompt and a default answer that will be returned on enter keypress.
# It keeps asking and echoes the answer on the same line until it gets y/n/Y/N or enter.
# I tried to get Highline to behave like this directly, but even though it's sophisticated, I didn't like the result.
# This isn't especially elegant, but it is straightforward and gets the job done.

require 'highline/import'
def yesno(prompt = 'Continue?', default = true)
  a = ''
  s = default ? '[Y/n]' : '[y/N]'
