This library is a data assertion tool and equality logic framework for PHP. It provides utilities to verify that two values, nested objects, or complex data types match based on their internal contents. The project distinguishes itself through the use of custom matching rules and configurable precision. It allows for the comparison of floating point numbers and dates using a defined margin of error to account for numeric precision loss. The framework covers deep value equality verification across scalars, arrays, and nested objects. It implements strict type enforcement to prevent implicit c

Rockstar is an esoteric programming language whose syntax is inspired by 1980s hard rock and heavy metal lyrics, making programs read like song lyrics. It uses poetic number literals, where the length of each word in a phrase is parsed as a decimal digit to initialize numeric variables, and pronoun-based variable references, where words like "it" and "they" resolve to the most recently assigned or compared variable at runtime. The language can be compiled to WebAssembly and run inside a web page for in-browser code execution. The language distinguishes itself through a lyric-driven parsing sy

collect.js is a dependency-free JavaScript library that provides a fluent, chainable interface for manipulating arrays and objects. It mirrors the Laravel Collection API, offering a consistent set of methods for data transformation across JavaScript and Laravel backend environments. The library stores collection data as plain arrays internally and supports fluent method chaining, where each method returns a new collection instance. The library distinguishes itself by closely replicating the Laravel Collection API in JavaScript, mapping each PHP method to an equivalent JavaScript implementatio

Generate Java types from JSON or JSON Schema and annotate those types for data-binding with Jackson, Gson, etc

Scala 3 is an open-source, statically typed programming language that compiles to JVM bytecode, combining object-oriented and functional programming paradigms. Its core identity is defined by a sophisticated type system that includes traits, generics, union types, and a dependent object type system where types can depend on runtime values through path-dependent and singleton types. The language distinguishes itself through several advanced type-level and metaprogramming capabilities. It features a contextual abstraction mechanism using given instances and using clauses for compile-time implic

is-thirteen es una biblioteca de validación de números y comprobador de igualdad numérica diseñada para verificar si una entrada dada es igual al valor trece. Funciona como una herramienta de clasificación de datos que identifica este valor específico a través de flujos de entrada numéricos, textuales y visuales. El proyecto incluye un clasificador de números basado en imágenes que utiliza aprendizaje profundo y análisis de redes neuronales para identificar representaciones visuales del número trece dentro de imágenes cargadas. La biblioteca cubre una variedad de métodos de validación, incluyendo igualdad aritmética exacta, coincidencia de valores aproximados dentro de rangos de tolerancia definidos, análisis de notación científica y coincidencia de patrones lingüísticos para formas escritas del número.

Tape is a TAP-producing test framework for Node.js that provides assertions, spies, subtests, and isolated test harnesses. It functions as both a test runner and an assertion library, outputting results in the Test Anything Protocol format for machine or human consumption.
