AGL a toy language that compiles to Go▲83
I spent the past 2 weeks making this toy programming language. I basically forked the Go scanner/parser, and changed the syntax to have functions return a single value. This enable proper Result/Option type to be used as well as propagating errors with an operator. I also wanted to have short "type inferred" anonymous functions to be able to use functions like Map/Reduce/Filter, without having to use 100 characters to specify the types.

Ts-Chan – Go-Like Concurrency Primitives for TypeScript/JavaScript▲60
Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol"…

Go-mapper – AutoMapper-style struct mapping for Go▲6
I’ve worked a lot with C# and .NET, and one tool I really missed when using Go was AutoMapper. So I built go-mapper, a lightweight Go package that helps map between structs — useful for converting DTOs to domain models, etc. Uses Go generics (1.18+) Supports shallow copy of fields Custom field transformations with fluent API Optional interface for struct-level control Example: type CreateUserDto struct { Name string Password string } type User struct { Name string PasswordHash string } mapper.CreateProfile(CreateUserDto{}, User{}, mapper.ForMember(func(u *User) any { return &u.PasswordHash…

SafePool – Type-safe object pooling for Go▲6
Frequent memory allocations can be costly in Go. Go's sync.Pool helps with object reuse but isn't type-safe and can introduce bugs. You need type assertions, and it's easy to accidentally return objects twice or forget to return them at all. SafePool provides type safety with Go generics, eliminating the need for type assertions and making pool usage safer and clearer. For objects that need to live across function boundaries, we added PoolManager. It tracks all objects obtained from pools and ensures they're all returned when the manager is cleaned up, preventing leaks across function calls.…
