gem_rbs_collection VS DefinitelyTyped

I saw no mention of RBS+Steep, the latter providing a LSP. I use it a lot and very much like it, although it's still young and needs love, but it's making good, steady progress! I've been very pleasantly surprised by some of the crazy things Steep can catch, completely statically!

You appear to be working on projects with Sorbet (which I tried to like but found it fell short in practice, notably outside of the app use case i.e it's mostly useless for gems) so it may be a tall order to try on those. Maybe you can give RBS+Steep a shot on some small project?

RBS: https://github.com/ruby/rbs

RBS collection (for those gems that don't ship RBS signatures in `sig`, integrates with bundler): https://github.com/ruby/gem_rbs_collection

Steep: https://github.com/soutaro/steep

VS Code: https://github.com/soutaro/steep-vscode

Sublime Text: https://github.com/sublimelsp/LSP

Vim (I'm working on it): https://github.com/dense-analysis/ale/pull/4671

For now there's a ruby/gem_rbs_collection repo now that's been started to grow a collection of signatures that RBS can pull from.

rbs collection detects the dependencies from Gemfile.lock. For example, if your Gemfile has an entry, gem 'rails', rbs collection finds dependencies gems, such as activesupport, railties, nokogiri and so on, from Gemfile.lock. Then it installs RBSs from ruby/gem_rbs_collection repository.

Currently, rbs collection downloads RBSs with git clone from ruby/gem_rbs_collection GitHub repository.

# Download sources sources: - name: ruby/gem_rbs_collection remote: https://github.com/ruby/gem_rbs_collection.git revision: main repo_dir: gems # A directory to install the downloaded RBSs path: .gem_rbs_collection gems: # Skip loading rbs gem's RBS. # It's unnecessary if you don't use rbs as a library. - name: rbs ignore: true # 👮👮👮 Add the following lines - name: pathname - name: logger - name: mutex_m - name: date - name: monitor - name: singleton - name: tsort - name: time - name: set

Sometimes, the community will provide unofficial type definitions. You can find it in the DefinitelyTyped repository (https://github.com/DefinitelyTyped/DefinitelyTyped), or search for @types/library-name on GitHub.

It's still there to this date, but I've lost my TS port in the sands of time.

> I really loved PHP, but now with go+templ (https://templ.guide) I personally don't have a use-case for PHP anymore, but that doesn't mean it's irrelevant for the world.

This is the first time I've heard of Templ. It looks cool and it was really easy to set up. Apparently there are IDE extensions to enable syntax highlighting and HTML auto-completion, but is there a way to type check the templates? One of the things I love about JSX as a templating language is that errors in your markup get reported as type errors [1]. If I write `` instead of `` and run `tsc --noEmit --watch`, TypeScript will complain until I fix the issue. You can even extend the types to support your own HTML custom elements.

Prior to React 18, it used to include an implicit children prop, making it suitable for components expected to have children. For a long time, though, the implicit children prop type has been removed according to React 18's type changes.

Additionally, because TypeScript has a well established and widely used install-base, there are already many different definition files in the wild for supporting non-TypeScript supporting projects. One of the more extensive collections of these typings lives at the DefinitelyTyped repository, which publishes the package's community typings under the package names @types/your-package-name (where your-package-name is the name of the project you're looking for typings of) that you can look for on your package manager.
