Diffy
A Ruby gem for generating diffs between strings or files using Unix diff with multiple output formats.
What is Diffy?
Diffy is a Ruby gem that provides an easy way to generate differences between two strings or files. It wraps the Unix diff command to produce accurate diffs and offers multiple output formats including plain text, colored terminal output, and HTML with inline highlighting. The library solves the problem of implementing diff functionality in Ruby applications without reinventing the diff algorithm.
Ruby developers who need to compare text or files in their applications, such as those building version control tools, code review systems, content management systems, or any application requiring change detection.
Developers choose Diffy because it provides a simple, reliable interface to the battle-tested Unix diff utility, eliminating the need to implement diff algorithms from scratch. It offers multiple output formats out of the box and flexible configuration options while maintaining performance and accuracy.
