Native Ruby bindings for the Lingua Rust library, bringing highly accurate language detection for short text and mixed-language text to Ruby, with confidence scores and ISO 639-1/639-3 language codes.

This module is a Ruby binding for the Abiword version of CMU’s Link Grammar, a syntactic parser of English.

List is a class of wrapped singly-linked list

Ruby wrapper for Redis listpack data structure

lithos is a self-contained embedded key-value store written from scratch as a native extension — no external database dependency. It uses a log-structured merge (LSM) tree: a write-ahead log makes every write durable, an in-memory sorted memtable flushes to immutable SSTables (with bloom filters), and compaction merges them. Keys and values are arbitrary binary strings; keys are kept in sorted order so you get ordered iteration and range scans, plus crash recovery via WAL replay. Windows MSVC (mswin) Ruby only.

LivingDead traces objects to see if they are retained or freed by MRI

Left-Leaning Red-Black Tree for Ruby.

Local FastImage Resize is an extremely light solution for resizing images in ruby by using libgd.

Reverse geocodes lng, lat pairs into country codes (plus State and Counties within the US). Runs locally, with no external dependancies, and is fast enough for large batch jobs

bcrypt() is a sophisticated and secure hash algorithm designed by The OpenBSD project for hashing passwords. The bcrypt Ruby gem provides a simple wrapper for safely handling passwords.

Ruby bindings for the Lora in-memory graph database. Exposes the embedded Rust engine as a native extension via Magnus/rb-sys, so queries run in-process without a separate server.

Runs the Lowess smoothing algorithm

A Ruby gem providing access to the HiGHS linear, quadratic, and mixed-integer programming solver via CLI.

A fast and simple in-place implementation of the luhn check algorithm in Ruby using a C extension.

This module allows Ruby programs to interface with the SQLite3 database engine (http://www.sqlite.org). You must have the SQLite engine installed in order to build this module. Note that this module is NOT compatible with SQLite 2.x.

Lulu merges the closest overlapping pair of map markers into a one whose area is the sum of the original two, located at their centroid. It repeats this until no overlaps remain. Some interesting data structures make this quite fast for all but pathologically bad data. Markers can be circles or squares. The user may provide a scale factor allowing the marker radius to have a different scale than distance between markers.

The LWES Light-Weight Event System is a framework for allowing the exchange of information from many machines to many machines in a controlled, platform neutral, language neutral way. The exchange of information is done in a connectless fashion using multicast or unicast UDP, and using self describing data so that any platform or language can translate it to it's local dialect.

Complete Ruby bindings for LZ4 compression library, including lz4.h, lz4hc.h, and lz4frame.h interfaces. Bundles the official LZ4 source code.
