middleman-deploy pushes from root instead of build dir - ruby

Question

Background
I'm using middleman-deploy to deploy to a github page for an organization.
It's my understanding that the middleman build dir (/build in this case) is what will get deployed to github. That is, the directory that contains files after a bundle exec middleman build, including the index.html file.
What I'm getting in my github repo is the root of the project. I'm using bundle exec middleman deploy --build-before
config.rb
activate :deploy do |deploy|
deploy.method = :git
deploy.remote = 'https://github.com/FiercePunchStudios/fiercepunchstudios.github.io.git'
deploy.branch = 'master'
end
Question
How do I deploy my middleman site to a github organization page, using middleman-deploy?

Thanks to #robinbortlik, there's a handy little extension right on the github issue. https://github.com/middleman-contrib/middleman-deploy/issues/114#issuecomment-168139237
#lib/build_cleaner.rb
class BuildCleaner < Middleman::Extension
def initialize(app, options_hash={}, &block)
super
FileUtils.rm_rf app.config[:build_dir]
end
end
::Middleman::Extensions.register(:build_cleaner, BuildCleaner)
#config.rb
require_relative "./lib/build_cleaner"
configure :build do
activate :build_cleaner
end
This deletes the build directory before the build action. Now you can just do a single command, like bundle exec middleman deploy --build-before
It's still not something I'd consider a fix, because I'd like to not have to add boilerplate to every middleman project I start. However, it's a convenient workaround that smooths out the deploy process for now.
