Very fast CRC32 calculation based on Intel's slicing-by-8 algorithm.

This gem contains C extension for calculating CRC32

Credo detector

A Ruby extension to interface with CRF++, the Conditional Random Fields library written in C++. You need to install libcrfpp to use this gem.

A libcriu wrapper for CRuby

CAST parses C code into an abstract syntax tree (AST), lets you break it, then vomit it out as code. The parser does C99. This fork supports Ruby 1.9.3, gemspec, and requires Hoe. The Rubyforge page above is documentation for the original version, but most things should be the same.

dAImond is a PyTorch-inspired deep learning framework for Ruby featuring automatic differentiation, neural networks, and a high-performance Rust backend for tensor operations. Achieves 89%+ accuracy on MNIST.

This gem implements pure Levenshtein algorithm, Damerau modification (where 2 character transposition counts as 1 edit distance). It also includes Boehmer & Rees 2008 modification, to handle transposition in blocks with more than 2 characters (Boehmer & Rees 2008).

Word game which deals with altering words adding, deleting or replacing letters.

The gem to operate low level I/O data buffer.

This Ruby extension implements a DataMatrix encoder for Ruby. It is typically used to create semacodes, which are barcodes, that contain URLs. This encoder does not create image files or visual representations of the semacode. This is because it can be used for more than creating images, such as rendering semacodes to HTML, SVG, PDF or even stored in a database or file for later use.

A Ruby gem with a C extension for high-performance scanning and redaction of 85 sensitive patterns — API keys, tokens, credentials, IBANs, national IDs, emails, phone numbers, and PII from 15+ countries. Optional Logger formatter, Rails filter_parameters adapter, and Rack middleware. Designed to sanitize text before sending to LLMs, logging systems, or any public/third-party API.
