Temp Dir With Ruby

Played around with few programming languages to handle temp dirs, but amongst the lot /me really liked ruby’s paradigm.

Mainly liked :

• yield for the win!

• Easy maintenance of code.

• Temp dir removal is assured.

Code to manage temp dir :

def in_tmp path = File.expand_path ”#{Dir.tmpdir}/#{Time.now.to_i}#{rand(1000)}/” FileUtils.mkdir_p( path ) yield( path ) ensure # This ensures temp dir removal. FileUtils.rm_rf( path ) if File.exists?( path ) end

The above method can be used as :

in_tmp do |tmpdir| puts “In tmp dir: #{tmpdir}” end

This code was improved with the help of a few hackers at #ruby, anyway there might be better ways to do this, do suggest your way below! Happy Hacking.
