zulip/tools/pre-commit

#!/usr/bin/env bash

# This hook runs the Zulip code linter ./tools/lint and returns true
# regardless of linter results so that your commit may continue.

# Messages from the linter will be printed out to the screen.
#
# If you are running this one machine hosting a Vagrant guest that
# contains your provisioned Zulip development environment, the linter
# will automatically be run through `vagrant ssh`.
