#!/bin/bash

days=${1:-1}

current_dir=$(pwd)

homebrew_prefix=$(brew --prefix)

for formula_dir in $(find ${homebrew_prefix}/Homebrew/Library/Taps -name "Formula" -type d); do
  cd $formula_dir
  
  formulas=$(git log --pretty=format: --name-status --since="${days} days ago" | sort | uniq | sed -e "s#Formula/##g;s#	#___#g")

  for formula in ${formulas}; do
    state=${formula:0:1}
    formula=${formula#*___}
    content="${formula_dir}/${formula}"
    name=$(echo $formula | sed -e 's/\.rb//g')

    if [ ! -f "${content}" ]; then
      printf "[%s] %-30s\n" "${state}" "$(sed -e 's/___/ -> /g' <<< ${name})"
      continue
    fi

    desc=$(cat "${content}" | grep "desc " | sed -Ee 's/.*desc "(.*)"/\1/g')
