Howto publish a git repository with ruby as zipfile - ruby-on-rails

Question

I am using OpenProject as project management software and I am not very familiar with ruby and rails, but using the gitolite-plugin works quite well.
I am looking for a solution to provide a link to the OpenProject users where they can directly download the gitolite-hosted repository as a zipfile.
Is that possible ?
I am willing to put pieces of code together, so even partially solutions and hints are welcome.
thx.

Nothing in oliverguenther/openproject-revisions_git would do a :
git bundle (full repo history in one file)
git archive (latest working tree as one zip file)
You would need to extend that plugin in order to expose that feature, implementing a ruby function to call git-archive on the right project, a bit like in this gist:
(extract)
# Runs the `git archive` command to pull your repository out
# into a tar or tar.gz and writes it to a temporary directory
#
# Args:
# * path - path within the repository to archive, defaults to the root
#
# Returns the path to the tar file
def archive(path=nil)
#archive_path = path || ''
create_tmp_directory
#tar_path = "#{#tmp_directory_path}/archive.tar#{#gzip}"
Dir.chdir #path
puts "Archived repository" if run_shell_cmd "git archive --prefix=#{#archive_path}/ #{#branch}:#{#archive_path} -o #{#tar_path}" and #verbose
Dir.chdir #pwd
#tar_path
end
