# tasks file for qb/ruby/gem/release

# NOTE  We do this because the `release` Rake task `bundler/gem_tasks`
#       provides **will** fail if there are any uncommitted files...
#       which is annoying as all hell when the dirt is just a dev submod that
#       is not used in the release version, but there does not seem to be
#       any options to ignore files or paths:
#       
#       https://github.com/bundler/bundler/blob/c4fc79a2bfed38335a3371300bea49286a371d83/lib/bundler/gem_helper.rb#L151
#       
#       So, we do the check first so we don't both with anything else if it's
#       going to fail (and it's the most common thing that gets in the way,
#       so it's nice to catch it early).
