Sorbet: Gradual typing of Ruby at Scale

sorbet.run

They've shown this quite some time ago, but it still didn't go further than the cute online demo, unfortunately. Really hope they release something tangible to play with.

If you didn't go through the presentation, the plan is to release Sorbet as an open-source product in 2019.

I don't think anything in the presentation suggests they're making this a product does it?

The shared timeline? What do you define as a product, btw. Is "rubocop" a product? - I'd say, yes. I'm sorry if I've confused you.

I thought 'product' meant something commercial - something with an income. I'd say Rubocop was a project but not a product.

I love the idea of gradual Ruby typing but I think I'm going to wait until Matz follows through with his promise to bake it into the language.

But if I were working in a shop that was considering moving off Ruby and this would convince them to stay on it, I'd very happily adopt it.

Matz has stated that it’s unlikely to happen for years (2040 was mooted recently). So, your strategy is more likely to leave you with a less scalable and more buggy code base for years to come.

Sorbet is compatible with existing Ruby, requires no syntax changes and can be transpiled into whatever official typing support comes into existence many years from now.

Give it a try, it’s good for you :-)

Can we actually try this though? 2019 appears to be the planned open source date.

This is interesting work, of course, and highly valuable ot existing Ruby codebases & organizations. But I do wonder if the interest in this among current Ruby shops suggests to anyone that choosing a different language/runtime for new development is best?
