Command::Cacheable

Command::Cacheable wraps the command line, optionally caching standard output for later, faster retrieval.

Installation

Add this line to your application's Gemfile:

gem 'command-cacheable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install command-cacheable

Usage

From the Svnx project:

    require 'command/cacheable/command'
    ls = Command::Cacheable::Command.new [ "ls", "/tmp" ]
    ls.execute
    
    lsc = Command::Cacheable::Command.new [ "ls", "/tmp" ], caching: true, cachedir: "/tmp/lscache"
    lsc.execute

    diff = lsc.output - ls.output

Command::Cacheable is specifically for caching commands, and does not have the flexibility that the Command gem does. For one, it does not cache standard error.
