Open Source Go Compilers for BSD

Gnostic is a command-line tool and Go library developed by Google for converting OpenAPI specifications (in JSON or YAML) to and from Protocol Buffer (protobuf) representations. It allows developers to handle OpenAPI documents in a strongly typed, language-neutral, and extensible way by generating structured data models that can be used across different programming languages supported by protobuf. Using these protobuf models, developers can safely parse, validate, and manipulate OpenAPI specifications, resolve dependencies, and export results as JSON, YAML, or binary files. Gnostic also provides a plugin interface similar to protoc, enabling integration with external API tooling and the generation of additional artifacts, such as annotated protobuf APIs, Go clients, and vocabulary summaries. It supports multiple OpenAPI versions (v2, v3) and Google Discovery Documents.

GopherJS compiles Go code to pure JavaScript code. Its main purpose is to give you the opportunity to write front-end code in Go which will still run in all browsers. Nearly everything is supported, including Goroutines (compatibility documentation). Performance is quite good in most cases, see HTML5 game engine benchmark. Cgo is not supported. GopherJS requires Go 1.16 or newer. If you need an older Go version, you can use an older Gopher release. GopherJS uses your platform's default GOOS value when generating code. Supported GOOS values are: linux, darwin. If you're on a different platform (e.g., Windows or FreeBSD), you'll need to set the GOOS environment variable to a supported value. gopherjs serve is a useful command you can use during development. It will start an HTTP server serving on ":8080" by default, then dynamically compile your Go packages with GopherJS and serve them.
