Installs the Dash docs for all the Ruby Gems in your Gemfile

install_dash_gem_docs.rb

#!/usr/bin/env ruby
#
# Prerequisites:
#   gem install bundler
#   bundle install

dependencies = `bundle show | grep '*' | awk '{print $2, $3}' | sed -e 's/(//' -e 's/)//'`.split("\n")

dependencies.each do |dependency|
  (gem_name, version) = dependency.split
  next if gem_name =~ /rails-assets/

  puts "Installing docs for #{gem_name} #{version} "
  system "open -g 'dash-install://repo_name=Ruby Docsets&entry_name=#{gem_name}&version=#{version}'"
  sleep 3
end

open -g doesn't bring Dash to the foreground every time it executes

shaved a yak, and created a Bundler plugin to do this. Really not sure how I feel about turning ~10 lines of code into a whole repo, but here it is. https://rubygems.org/gems/bundler-install_dash_docs

I guess it started when I was unhappy with the system call not breaking the args into separate strings, and then no escaping on the url, and then not using the parser provided by Bundler, and then, and then, and then.
