Automatically include ticket number from branch name into git commit messages
View prepare-commit-msg
# If you use branch names with JIRA ticket numbers in them, e.g. feature/ABC-4324-do-something,
# this includes automatically the ticket number (ABC-4324) at the start of the the commit message.
# This way, it's later easy to see which change was done for which ticket, without any manual effort.
# You need to copy or link this file into .git/hooks/prepare-commit-msg
# You can customize which branches should be skipped when prepending commit message.
