Release Notes

soutaro/steep (steep)

v2.1.0

Compare Source

Steep 2.1 opens the running server to commands other than the editor's. steep langserver now binds
the per-project UNIX socket that steep server serves, so steep check and steep query reach the
language server the editor is already running instead of needing a daemon of their own, and the new
steep query diagnostics reads the diagnostics that server has already computed rather than starting
a type check of its own. Both are aimed at tools that edit files on disk and want fast feedback,
coding agents in particular.

The type checker gains support for Ruby 3.4's it block parameter, and RBS is updated to 4.2.0.

Type checker core

• Infer tuple types for array literals against pair interface hints like Hash::_Pair (#​2253)
• Accept a type alias as the type of a lambda's block parameter (#​2263)
• Build expensive log tags only when something is logged (#​2271)
• Accept block-pass arguments for optional blocks (#​2261)
• feat: support the it block parameter (#​2238)
• Fix UnreachableBranch on == against literal supertype (Symbol / Integer / String) (#​2223)

Commandline tool

• Stop steep query definition from hanging on inline sources (#​2276)
• Serve steep query/check through the language server's UNIX socket (#​2273)
• Add steep query diagnostics (#​2274)
• Point the Steepfile template, README and CLAUDE.md at rbs collection (#​2269)

Miscellaneous

• Update RBS to 4.2.0 (#​2277)
• Fix bin/steep-check.rb for the current API (#​2270)
• Update RBS to 4.2.0.pre.1 (#​2267)
• Fix Ruby warnings printed while running tests (#​2266)
