git log does not show any output from prepare-commit-msg script

[JuliusHenke]

I would like to report an issue I stumbled upon, which I think is a bug:

When using a bash script for a prepare-commit-msg hook, no echo output of the script is shown in the lefthook log. I created a repo to reproduce this: https://github.com/JuliusHenke/lefthook-prepare-commit-msg-issue

Maybe I am missing something, but since it works with a script for pre-commit, I think this is not intended behaviour.

Hey! Yes, this is a bug. Initially it was a hack because lefthook uses prepare-commit-msg hook for auto synchronization, but we don't want to see the output of lefthook on every commit, so we suppressed the output. But if you manually specify prepare-commit-msg hook, there is no need to suppress the output I think. I'll put it on my radar.

To workaround this for now you can use set the LEFTHOOK_VERBOSE=true when running git commit or lefthook run ...
