gval is a versatile expression evaluation library for Go, enabling developers to parse and evaluate expressions dynamically. It supports a variety of expression types, including arithmetic, logical, and text-based, and allows for the composition of custom languages by replacing functions and operators. ​

...Offer helpers to isolate side effects into lazily executed functions (IO). Expose a consistent set of compositions to create new functions from existing ones. For each data type, there exists a small set of composition functions. These functions are called the same across all data types, so you only have to learn a small number of function names. The semantic of functions of the same name is consistent across all data types.

go-jsonnet is a pure Go implementation of the Jsonnet data templating language, which extends JSON with variables, functions, imports, and a standard library so you can generate complex configuration safely. Instead of hand-maintaining massive JSON files, you write concise, reusable templates that evaluate to JSON or YAML, with deterministic semantics and rich error messages. The repository ships both an embeddable VM for Go programs and a command-line interpreter, making it easy to...

mo - Monads is a functional programming utility library for Go that introduces monads and related abstractions using modern Go generics. The project brings well-known FP constructs such as Option, Result, Either, Future, IO, and Task into the Go ecosystem to help developers write safer and more composable code. By leveraging generics introduced in Go 1.18+, the library provides strong type safety without relying on reflection or code generation. It is particularly useful for managing...

...Rendering was driven by a graphics backend so that animations, text, and compositing could be smooth without relying on heavyweight native bindings. The library encouraged idiomatic Go patterns—composition and interfaces—while offering a retained-mode tree of views for common desktop interactions. Although the project is no longer actively developed, it remains a reference for how to bridge Go’s concurrency model with UI event loops and rendering pipelines. Developers still look to it for examples of input handling, focus management, and custom drawing in pure Go environments.
