# Resquire

Reduce your redundant gem depenencies with resquire, which figures out which gems are redundant so you can require less gems for your ruby projects while still retaining the same functionality! By reducing redundant gems, you can make your application faster!

## Installation

While this gem is still in development, but when it's all done you'll be able to install it like so:

    $ gem install resquire

## Usage

```ruby
require "resquire"

# you can add gems when you create a new analyzer, as an array
analyzer = Resquire::Analyzer.new(:gems => ['colorize', 'packetfu', 'lolize'])

# you can also add gems individually
analyzer.add_gem('pcaprub')
# => true

# or as an array
analyzer.add_gems(['ipaddr', 'socket', 'thread'])
# => true

# we can check which gems the analyzer has to work with
analyzer.gems
# => ["colorize", "packetfu", "lolize", "pcaprub", "ipaddr", "socket", "thread"]

# quickly check ammount of permutations ( to see wtf we're about to get outselves into )
# no, srsly, like, you can easily have 20 gems; and that's 2,432,902,008,176,640,000 permutations dog, fo real 
# you can try splitting them up into smaller batches of roughly ~13
analyzer.permutations
# => 5040

# you can get an array of the redundant gems
analyzer.redundant_gems
# => ["pcaprub", "ipaddr", "socket", "thread"]

# you can choose not to shuffle the permutated array, may be better for larger gem groups
# since we're not pre-generating the permutations -- we're simply looping through the
# possibilities via an enumerator.
# true by default, since I find it to be generally nicer
analyzer.redundant_gems(:shuffle => false) 
# => ["pcaprub", "ipaddr", "socket", "thread"]

# you can also choose to to display a small progresss indicator or not
# true by default, since I find it to be generally faster
analyzer.redundant_gems(:progress_bar => false) 
# => ["pcaprub", "ipaddr", "socket", "thread"]

# or the new optimized gem listing as an array with the redundancies
# these would be the gems you'd want to require in your application now
analyzer.optimized_gems
# => ["colorize", "lolize", "packetfu"]
```
