So I asked about conditionals in Rake and basically everybody 
told me the concept is ridiculous, but I could maybe use invoke. 
I'm thinking maybe I asked the wrong question, so here's some more
detail so we can either find me a viable solution or confirm I'm crazy.

I have a rake task that combines and minifies all my CSS and JS into 
one file each. I want to automate that task so that it runs before 
each deploy.

Ideally, I type 'cap deploy' as per normal, it runs the minifier tasks, 
commits any changes to master, pushes that to GitHub and then runs my 
normal deploy.

My concern is the automatic commit and push. I need to ensure I have a 
clean index before the minifier runs so I don't inadvertently commit 
the wrong shizzy or the right shizzy under the commit message about 
minification.

My original question was because I only wanted to proceed with the 
minification and deploy if the task found my index was clean. But 
maybe there is a better way?

How would you do it?

minify.rake

task :minify do
  raise "You've uncommitted changes" unless `git status`.include?("working directory clean")
  `minify && git commit -am "Minify"`
end

task :deploy => :minify do
  # Do the deploy
end
