viewing dependency tree for non-installed packages [SOLVED]

Pactree only seems to work for installed packages so I was wondering if there was any alternative that could work with any package (installed or not).

Well it's not as fast as pactree but I hacked this together for you:

#!/bin/bash

pactree () {
  echo "$2|--$1" | cut -c4-
  for dep in $(pacman -Si $1 2>/dev/null | awk -F':' '/Depends On/ { print $2 }')
  do
    dep=$(echo $dep | egrep -o "^[a-z0-9._-]+")
    [[ -n $dep ]] && pactree $dep "$2|  "
  done
}

pactree $1 ""

Perhaps you should replace the occurences of "pactree" with something else.

Edit: Prettier output.

God, I need some coffee. This finds the reverse dependencies.

You need to change %N to %E like so

for pkg in $(expac -S '%E' $1); do

to find dependencies.
