callcache

A simple Ruby library for caching the results of a call to any method or function call.

Great for speeding up program execution for when making long calls to things like web services.

Installing

Install from the command line

# gem install callcache

Example

The following will call exp_fun and print out the results of the call. The result will be stored in a file cache, and the next time the same call is made, the cached results will be returned.

require 'call_cache'

def exp_fun( start_num, end_num )
    ret_val = 1
    
    start_num.upto( end_num ) do |num|
        ret_val = ret_val * num
    end
    
    return ret_val.to_s.size
end

blog_source = CallCache.call( 'Net::HTTP.get', :pars => [URI.parse('http://feeds.feedburner.com/adamw523?format=xml')] );

p blog_source.size
p CallCache.call( 'exp_fun', :pars => [1, 10000], :options => {:ttl => 10})
