#!/usr/bin/env bash

# Creates local version tags based on cookbook metadata.rb change history
# Usage: bash tagify-cookbook [cookbook_name]

cookbook=${1:-some_cookbook}

git log --pretty=format:"%h" cookbooks/$cookbook/metadata.rb | while read ref; do
    tag="$cookbook-$(git show $ref:cookbooks/$cookbook/metadata.rb | grep "^version '" | sed -E "s/.* '(.*)'/\1/g" )"
    echo "ref: $ref -> $tag";
    git tag $tag $ref
