Crystal is a statically typed, compiled programming language designed for high performance and memory safety. It leverages an LLVM-based compiler to translate source code into optimized machine-executable binaries, while its type-inference-based static analysis enforces strict safety rules during the build process. The language distinguishes itself through a fiber-based concurrent runtime that manages lightweight execution units for asynchronous input and output without blocking the main process. It also features a powerful compile-time macro system that allows for the inspection and transfor

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 is a regular expression library designed for the validation and identification of mobile phone numbers from mainland China. It provides the structural rules and digit constraints necessary to verify that phone numbers follow the correct regional format. The library includes specific patterns to determine the telecommunications provider based on regional prefixes. It also features filters to distinguish between standard voice numbers and IoT or data-only plans. The project covers broad data validation capabilities, including input format verification and carrier identification.
