Deploying a Git subdirectory in Capistrano

Without any dirty forking action but even dirtier !

In my config/deploy.rb :

set :deploy_subdir, "project/subdir"

Then I added this new strategy to my Capfile :

require 'capistrano/recipes/deploy/strategy/remote_cache'

class RemoteCacheSubdir < Capistrano::Deploy::Strategy::RemoteCache

  private

  def repository_cache_subdir
    if configuration[:deploy_subdir] then
      File.join(repository_cache, configuration[:deploy_subdir])
    else
      repository_cache
    end
  end

  def copy_repository_cache
    logger.trace "copying the cached version to #{configuration[:release_path]}"
    if copy_exclude.empty? 
      run "cp -RPp #{repository_cache_subdir} #{configuration[:release_path]} && #{mark}"
    else
      exclusions = copy_exclude.map { |e| "--exclude=\"#{e}\"" }.join(' ')
      run "rsync -lrpt #{exclusions} #{repository_cache_subdir}/* #{configuration[:release_path]} && #{mark}"
    end
  end

end


set :strategy, RemoteCacheSubdir.new(self)
