  • Sorbet: Stripe's Type Checker for Ruby
    6 projects | news.ycombinator.com | 29 Mar 2022
    We discovered a bug in `srb init` for Ruby 3.1 recently that a teammate of mine is working on fixing at the moment. It's likely that if you tried again in a few days it'll have been fixed. Sorry about that, totally agree that the out-of-box experience should just work.

    I wrote up an FAQ about the state of Ruby 3 and RBS here:

    https://sorbet.org/docs/faq#when-ruby-3-gets-types-what-will...

    The tl;dr is that RBI files (not RBS files) will probably always be the preferred way to declare types for third party code (because it will always support exactly the same set of features that Sorbet does). We have some people in the community look into teaching Sorbet to read the RBS format, but the existing parsers for RBS files are written in Ruby and are very slow, and there are some ambiguities in the spec that make writing a third party parser that compiles to native code tricky. You can see an attempt to write a fast RBS parser in C++ here[1], but again given that RBI files do everything we need them to right now and we have other features people are asking us for, we haven't prioritized RBS support incredibly highly.

    Sorbet works completely fine without RBS files!

  • Open-Sourcing the Sorbet (Ruby) VS Code Extension

    This article might help clear some things up:

    tl;dr:

    - RBS files are what Ruby 3 uses to describe types in separate files

    - RBI files are what Sorbet uses to describe types in separate files

    - Sorbet invented its RBI file syntax before RBS files existed. RBI files use the same syntax for types and signatures as in type annotations that live inside `*.rb` source code with Sorbet.

    - We've been meaning to add support to Sorbet to consume both RBI files and RBS files, but we haven't had a chance to get around to it.

    If someone beat us to it and implemented support for RBS files in Sorbet that would be amazing! Shopify took an early stab at implementing an RBS parser in C++ for performance[1], but I'm not sure what the status of it is today.

  • Sorbet Compiler: An experimental, ahead-of-time compiler for Ruby

    (disclaimer: I work on the Sorbet team)

    I think I understand GP's motivation: RBI files and RBS files are two different formats, and as a user of the language, people tend to want to use the officially blessed solution the language provides.

    In case you weren't aware, parlour[1] is a popular open source project for working with RBI files. I believe it supports transparently converting between RBI files (Sorbet) and RBS files (Ruby 3).

    There is also rbs_parser[2], a C++ parser for RBS files to convert them to RBI files, written by Shopify, a major user of Sorbet.

    Stepping back: I haven't personally read many complaints from Sorbet users describing how the current state of RBI/RBS interop gets in the way of what they can actually do with Sorbet. Almost all the feature requests we get about Sorbet (both inside Stripe and outside) are for fixing bugs or implementing new language-level features. RBI files as implemented seem to work.

    Sorbet already has an extensive set of RBI files covering the Ruby standard library (at least as good or better to my knowledge than any existing repository of types for RBS files), and there are plentiful tools for working with RBI files, listed here.[3]

    If lack of first-party RBS support in Sorbet is holding you back from trying Sorbet, I'd strongly encourage you to give Sorbet a try anyways! Many people have shared great experiences adopting Sorbet in their Ruby codebases.
