FileCache

FileCache is a file-based caching library for Ruby. It’s available for download from RubyForge

Installation

gem install -r filecache

(On a Unix-like system you’ll probably want to run that with sudo.)

Synopsis

require 'rubygems'
require 'filecache'

cache = FileCache.new
cache.set(:key, "value")
puts cache.get(:key)     # "value"
cache.delete(:key)
puts cache.get(:key)     # nil

# create a new cache called "my-cache", rooted in /home/simon/caches
# with an expiry time of 30 seconds, and a file hierarchy three 
# directories deep
cache = FileCache.new("my-cache", "/home/simon/caches", 30, 3)
cache.put("joe", "bloggs")
puts(cache.get("joe"))   # "bloggs"
sleep 30
puts(cache.get("joe"))   # nil
