I am trying to get husky to launch commitizen in a pre-commit hook. Works fine on Linux. On Mac, not so much.

#!/bin/bash
exec < /dev/tty && cz commit || true

It looks like polling is broken on Mac because this causes CZ to crash, and the errors seem related to polling keyboard input and not being able to set up an event delegate.

Has anyone cracked this on Mac and how did you get around this thorny problem?

  • I'm not familiar with Commitizen, but why can't you just do cz commit < /dev/tty? Commented Apr 15 at 19:08
  • @Barmar, ...that's true, but on this two-line script I can't see what would have changed; this exec usage existed back then. Commented Apr 15 at 19:47

    It would improve the question to have the details of the "crash" -- what specific error message did it emit to lead you to think that "polling is broken"? Show, don't tell. Commented Apr 15 at 19:48

    That should certainly be included in the text of the question itself. Commented Apr 15 at 21:23
