Better way to query facts

Facter has some annoying bug where it won’t always print all facts when called like facter fact, ones that require dynamic lookups etc just won’t print.

This is a long standing bug that doesn’t seem to get any love, so I hacked up a little wrapper that works better.

#!/usr/bin/ruby
 
require 'facter'
require 'puppet'
 
Puppet.parse_config
unless $LOAD_PATH.include?(Puppet[:libdir])
    $LOAD_PATH << Puppet[:libdir]
end
 
facts = Facter.to_hash
 
if ARGV.size > 0
    ARGV.each do |f|
        puts "#{f} => #{facts[f]}" if facts.include?(f)
    end
else
    facts.each_pair do |k,v|
        puts("#{k} => #{v}")
    end
end

It behaves by default as if you ran facter -p but you can supply as many fact names as you want on the command line to print just the ones requested.

$ fctr uptime puppetversion processorcount
uptime => 8 days
puppetversion => 0.25.2
processorcount => 1
