Open-source alternatives to TinyPinyin

This is a dictionary-based Chinese Pinyin transliteration library used to convert Chinese characters into Pinyin with support for various tone styles and formats. It provides specialized utilities for polyphonic character resolution to manage multiple pronunciations and a generator for extracting the first letter of characters to create searchable index strings. The library includes a formatter for converting names into Pinyin following official international travel document and passport spelling standards. It also features a tool for transforming Chinese text into hyphenated or dotted string

ToolGood.Words is a sensitive word filtering library and text sanitization component designed for high-performance detection and masking of prohibited terms. It provides tools for Chinese text normalization, pinyin transliteration, and the replacement of banned words with placeholders. The project is distinguished by its ability to uncover obfuscated language through a pinyin transliteration engine and phonetic-based detection. It identifies sensitive content hidden by phonetic substitutions, first-letter initials, or intentional misspellings by mapping Chinese characters to pinyin representa

SnowNLP is a Python library for Chinese natural language processing. It provides tools for text segmentation, sentiment analysis, document classification, and phonetic transliteration. The library includes capabilities for training and saving custom machine learning models for tokenization and sentiment analysis using raw training datasets. It covers a range of linguistic processing areas, including parts of speech tagging, sentence splitting, and text similarity measurement. The toolkit also provides utilities for extracting key information through text summarization and calculating word im

Any-rule is a multi-platform regular expression tool that provides a curated catalog of over 70 ready-to-use patterns for validating and extracting common data formats. The project separates its static regex collection from editor-specific plugins, allowing the same pattern library to be accessed through VS Code, IntelliJ IDEA, Alfred Workflow, and a web interface. The tool enables keyword-based pattern retrieval, letting users search for the correct regex by typing descriptive terms rather than remembering exact syntax. It covers a broad range of validation needs including email addresses, U

This project is a CJK input method framework and configuration set designed for the Rime input engine. It provides a comprehensive system of schemas and dictionary packs to optimize Chinese character entry through pinyin and double-pinyin workflows. The framework is distinguished by its use of Lua-powered extensions that add dynamic utilities, such as inline mathematical calculators, automated timestamps, and text formatting, directly to the input interface. It also features refined word libraries and language models specifically tuned to improve prediction accuracy and first-choice hit rates

Cherry Markdown is a web-based Markdown editor and parsing engine that converts markup text into sanitized HTML with a real-time synchronized preview pane. It functions as a rich text interface and WYSIWYG tool, providing a system for transforming markup strings into HTML documents or portable formats. The project distinguishes itself through high-performance rendering and a flexible extensibility model. It uses virtual DOM diffing and partial rendering to maintain responsiveness in large documents, and it allows for the creation of custom parsing rules and specialized HTML components via a p

This project is a PHP compatibility layer that implements the native ctype extension functions in pure PHP. It serves as a polyfill to ensure that character type validation remains consistent across different PHP versions and server environments. The library functions as a portability bridge, providing fallback implementations for environments where the native C extension is missing. This allows applications to maintain stability and consistent behavior regardless of the specific hosting platform or server configuration. The codebase focuses on PHP extension polyfilling and cross-platform de

Go Package of validators and sanitizers for strings, numerics, slices and structs

This repository is a collection of JavaScript coding challenges and a comprehensive interview guide. It provides reference implementations and educational examples designed to help developers master language fundamentals and prepare for technical interviews. The project covers a wide array of specialized implementations, including functional programming patterns like currying and partial application, as well as asynchronous patterns for concurrency control. It also includes practical examples of Document Object Model manipulation and the implementation of common data structures such as stacks

Locutus is a multi-language utility library and polyfill collection written in TypeScript. It provides a comprehensive set of implementations for standard library functions from various programming languages, enabling developers to use familiar semantics and behaviors across different technical environments. The library functions as a cross-language standard library, porting core logic and utilities from diverse languages into a type-safe TypeScript toolset. It focuses on maintaining consistent behavior through a polyfill-based design that replicates the original functionality of these foreig
