Rake task depend on other rake task

Question

I have rake tasks which provide functionality for Git. I would like to be able to call rake git:pull which should recognize that the directory @source_dir does not exist and then it will call git:clone before attempting git:pull. It is possible to add such a dependency to my tasks?

namespace :git do
  desc "Download and create a copy of code from git server"
  task :clone do
    puts 'Cloning repository'.pink
    sh "git clone -b #{@git_branch} --single-branch #{@git_clone_url} #{@source_dir}"
    puts 'Clone complete'.green
  end

  desc "Fetch and merge from git server, using current checked out branch"
  task :pull do
    puts 'Pulling git'.pink
    sh "cd '#{@source_dir}'; git pull"
    puts 'Pulled'.green
  end

  desc "Shows status of all files in git repo"
  task :status do
    puts 'Showing `git status` of all source files'.pink
    sh "cd #{@source_dir} && git status --short"
  end
end

Answer 1

Typically you just declare dependencies like this:

task :pull => :clone do
  # ...
end

Or in the case of multiple dependencies:

task :status => [ :clone, :pull ] do
  # ...
end
