# Zulip notification post-receive hook.
|
|
#
|
|
# The "post-receive" script is run after receive-pack has accepted a pack
|
|
# and the repository has been updated. It is passed arguments in through
|
|
# stdin in the form
|
|
# <oldrev> <newrev> <refname>
|
|
# For example:

# aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/main
