Utility script to parse ticket number out of branch name

contrast-commit.sh

#!/bin/bash

### Contrast specific utility script
### - Automatically formats a commit message based on the Jira ticket found in the branch name
### ARG1 = "commit text", ARG2 = "-skip" flag

# get commit message from arg
if [[ $1 == "" ]]; then
    echo "No commit message given. Try again: -> commit \"message\""
    exit 1;
else
    message=$1;
fi
# store if skip flag
skipValidation=$2
# get branch name
branch=$(git symbolic-ref --short HEAD)
# rip out 'CONTRAST-#####'
regex="^.[A-Z]{7}(-)[0-9]*"

# if we find a ticket in the branch name, try to commit
if [[ $branch =~ $regex ]]; then
    ticket=$BASH_REMATCH
    commit="$ticket $message"
    if [[ $skipValidation != "-skip" ]]; then
        read -p "Does this look good to commit? (y/n) -> \"$commit\"" confirm && [[ $confirm == [yY] ]] || exit 1;
    fi
    git commit -m "$commit"
else
    echo "Branch with name: '$branch' is invalid."
    exit 1;
fi
