    Project mention: Bouncer - An extensible validation library for your data with sane defaults. | | 2022-02-22

    You're welcome :) Well, I could think of many scenarios such zipcode, uuids, etc, that represent world information per-se, also in circunstances where you should validate fields that depend on others, or even when tangling with regex validation. You could check Respect/Validation out ( that does something similar or Rakit/Validation ( They present a nice API to work with and a structure closer to yours.

  • ozzo-validation

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

    Project mention: Gin vs Echo framework | | 2022-05-13

    Gin comes with built-in "validation", while Echo recommends the same validator. I am also not a fan of magic struct tags, so I would probably prefer either writing my own or using something like ozzo.

  • glslang

    Project mention: Need guidance on SPIRV reflection | | 2022-05-20

    So I use the glslang project, which is the reference compiler for glsl, to get my SPIRV. It's not as fast, but that's not a concern for me.

  • PKHeX

    Pokémon Save File Editor

    Project mention: Questions & Help Thread | | 2022-06-11

    According to PkHeX data it is shiny locked... Source

  • marshal.ts

    A new full-featured and high-performance TypeScript framework for enterprise applications.

    Project mention: What's New in Python 3.11? | | 2022-06-26

    You might be (very) interested in this project then:

    The guy behind it made a PR to typescript proposing runtime availability of types[0], got rejected, and got going on it by himself. And he already has PoC libraries with the equivalent of Pydantic and FastAPI (using runtime types for (de)serialization).

    I really hope this experiment works out and that it gains traction, because it's a massive value add to TS IMO.
