When I am pushing to remote Git repo, the push was rejected because...

Git' pre-push hook can be configured in repo by repo.

gitlab-org/gitlab repo introduced it with Lefthook gem.

Due to Ruby packages (via Rubygems), I need to update all the packages corresponding Gemfile/Gemfile.lock on HEAD after:

$ git checkout master (or main) && git pull

While I just wanted to modify some Markdown, why need to update all Ruby packages?

Here is the trouble I had this morning when just docs are to be updated, which demotivate me for a while:

$ git push origin HEAD
Lefthook v0.7.5

For long time, it has been that independency from Ruby looks better to me in these cases (for Git hooks).

Life is too short for me to understand why it is.
