# A GIT Hook to Pregenerate a Commit Message with an elapsed working time taken from the time tracker ActivityWatch. A `ref #123 @1.h` message like is generated taking the activity number from the branch name and te time from ActivityWatch Web API. Requires JQ in order to add all the events recorded by ActivityWatch
#
# Usage:
#
# copy this file under "${GIT_WORKING_TREE}/.git/hooks/prepare-commit-msg and set execution permitions
#
# Requirements:
#
#   ActivityWatch (https://activitywatch.net/)
#   JQ (https://stedolan.github.io/jq/)
#   OpenProject (Optional - https://www.openproject.org/)
#   Zenity (https://gitlab.gnome.org/GNOME/zenity)
#
# It uses OpenProject commit message format (1)
# to register working time & costs assosiated to a work package
# Working time is the result of the recorded activity on the host since the last commit.
# in case the file /tmp/check-in-work exists, it uses that timestamp for the working window
# The events can be manually selected, with a preset test filter in order to exclude certain applications. The dialog is handled by Zenity.
# The tracked activities set is defined by the check-in-work file
