gem_rbs_collection VS typings

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

I really like TypeScript. I think it reduces the pain of developing JavaScript applications quite a lot, thanks to type checking and other neat features. Visual Studio Code also offers a really nice code completion. And I know that I can make it work with React by using typings + DenifitelyTyped.

I think git clone is a good compromise for now. It is the same phase of tsd or typings of TypeScript. We needed a simple RBS manager now as you can see from the previous article.
