Question 1

How do I set up Steep for an existing Ruby project?

Accepted Answer

Run steep init to create a Steepfile, use rbs prototype to generate signature drafts from your code, then add annotations and run steep check to start type checking incrementally.

Question 2

Steep or Sorbet: which is better for Ruby type checking?

Accepted Answer

Steep focuses on gradual typing with separate RBS files and manual annotations, while Sorbet offers more inference and Rails integration. Choose Steep for explicit control and incremental adoption; Sorbet for more automated checking.

Question 3

Can Steep handle dynamic Ruby code like metaprogramming?

Accepted Answer

Steep struggles with dynamic features because it requires explicit type declarations. You may need to mark such code as untyped or skip type checking, limiting its effectiveness.

Question 4

How to integrate Steep with CI/CD pipelines?

Accepted Answer

Use the provided Rake tasks by adding Steep::RakeTask to your Rakefile, then configure it to fail on type errors, allowing seamless integration into build processes for continuous validation.

Question 5

What are common Steep errors and how to fix them?

Accepted Answer

Errors like MethodDefinitionMissing indicate missing method implementations in RBS files. Fix by updating signatures to match code or adding correct type annotations based on steep check output.

Question 6

Does Steep work well with Ruby on Rails applications?

Accepted Answer

Steep can be used with Rails, but it requires manual type signatures for Rails components and additional configuration. It's not natively integrated, so expect setup work for models and controllers.
