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

Documentation.js is a multi-purpose documentation tool that parses JSDoc annotations from JavaScript and TypeScript source files to generate formatted API documentation. It functions as both a documentation generator and a JSDoc linter, scanning source code for non-standard or incorrect annotations and returning human-readable warnings to enforce documentation quality. The tool operates through a pipeline-based architecture that parses JSDoc comments into an abstract syntax tree, validates annotations against style and correctness rules, and outputs documentation through interchangeable plugi
