Hi all,
Short version: -------------- Install the latest rubygem-yast-rake (>= 0.2.26) and use "rake check:rubocop" for running Rubocop. Long version: ------------- some time ago I introduced support for parallel test to speed up running units tests, see [1]. You probably noticed that running Rubocop also might take quite some, esp. in large packages like yast2 or yast2-storage-ng. It is slow because Rubocop checks the files sequentially one by one. We can easily make it faster by running the checks in parallel. Just get the list of files to check and split it into groups according to the number of processors. Then pass each group to a separate Rubocop process. Check [2] if you want to see the details. This parallel Rubocop is now available as the "rake check:rubocop" task. If you want to automatically fix the found issues then run "rake check:rubocop:auto_correct". I have enabled parallel Rubocop also in the Travis builds [3], it can help there a bit as well, see below. Some Numbers ------------ I have measured the speed up in the yast2-storage-ng package: - Running Rubocop locally: the needed time went down from 44s to 12s (~3.6x faster on a quad core CPU with HT enabled) - In Travis: from 69s to 47s (~1.5x faster - Travis machines have about 1.5x CPU power so this is the maximum we can get) Enjoy!
