Cregexp is a library of commonly used regular expressions, written in Ruby.

A crit bit tree, also known as a Binary Patricia Trie is a trie (https://en.wikipedia.org/wiki/Trie), also called digital tree and sometimes radix tree or prefix tree (as they can be searched by prefixes), is an ordered tree data structure that is used to store a dynamic set or associative array where the keys are usually strings. Unlike a binary search tree, no node in the tree stores the key associated with that node; instead, its position in the tree defines the key with which it is associated. All the descendants of a node have a common prefix of the string associated with that node, and the root is associated with the empty string. Values are normally not associated with every node, only with leaves and some inner nodes that correspond to keys of interest. For the space-optimized presentation of prefix tree, see compact prefix tree. This code is a wrapper around https://github.com/jfager/functional-critbit.

For cropping image

Crops images based on entropy: leaving the most interesting part intact. Don't expect this to be a replacement for human cropping, it is an algorythm and not an extremely smart one at that :). Best results achieved in combination with scaling: the cropping is then only used to square the image, cutting off the least interesting part. The trimming simply chops off te edge that is least interesting, and continues doing so, untill it reached the requested size.

Take a series of screenshots while running your cucumber test suite

A library of cucumber step definitions, which allow you to use a human to assert conditions during acceptance tests. Some requirements are simple for a human to confirm, but are very difficult to assert using automation. Farmer allows us to include human confirmation into our normal testing flow. For example, we needed to verify that certain portions of an image were 'blacked out'.
