prepare-commit-msg git hook

prepare-commit-msg

#!/bin/sh

ticket=$(git symbolic-ref --short HEAD | sed 's/.*\/\([a-zA-Z]*\)-\([0-9]*\).*/JIRA \1-\2/g')
original_msg=$(cat $1)
echo "\n\n$ticket\n$original_msg" > $1

If you want to use this with vim fugitive, you have to check if the message already has the ticket (vim fugitive does its commit using git commit -F file_with_commit_msg):

#!/bin/sh

ticket=$(git symbolic-ref --short HEAD | sed 's/.*\/\([a-zA-Z]*\)-\([0-9]*\).*/JIRA \1-\2/g')
original_msg=$(cat $1)
if ! [[ ${original_msg} =~ ${ticket} ]]; then
    echo "\n\n$ticket\n$original_msg" > $1
fi
