Use fzf to filter and select the search result from pacman (or pacaur)

pacfzf

#!/bin/bash

if [[ -z $(command -v fzf) ]]; then
  echo "You don't have fzf!!"
  exit -1
fi

# collapse pacaur search result into oneline each entry
collapse() {
  head=''
  rest=''
  first=1
  while IFS='' read -r line || [[ -n "$line" ]]; do
    if [[ ${line:0:1} == " " ]]; then
      rest="$rest $line"
    else
      if [[ $first -ne 1 ]]; then
        printf "%s\t%s\n" "$head" "$rest"
      fi
      first=0
      head="$line"
      rest=''
    fi
  done
  printf "%s\t%s\n" "$head" "$rest"
}

PAC=pacman
if [[ -n $(command -v pacaur) ]]; then
  PAC=pacaur
fi

target=`$PAC -Ss --color=always "$@" | collapse | fzf --ansi --multi \
  | awk -F'[/ ]' '{print $2}'`
if [[ -n "$target" ]]; then
  $PAC -S $target
