Kaitai Struct: declarative language to generate binary data parsers in C++ / C# / Go / Java / JavaScript / Lua / Nim / Perl / PHP / Python / Ruby / Rust

An idiomatic Go (golang) validation package. Supports configurable and extensible validation rules (validators) using normal language constructs instead of error-prone struct tags.

Zygo is a Lisp interpreter written in 100% Go. Central use case: dynamically compose Go struct trees in a zygo script, then invoke compiled Go functions on those trees. Makes Go reflection easy.

An interesting go struct tag expression syntax for field validation, etc.

A minimal, developer-friendly pretty-printer and debug dumper for Go structs, inspired by Laravel’s dump() and Symfony’s VarDumper.

Faygo is a fast and concise Go Web framework that can be used to develop high-performance web app(especially API) with fewer codes. Just define a struct handler, faygo will automatically bind/verify the request parameters and generate the online API doc.
