Irb 20th anniversary memorial session: Reish and Irb2
summary
Irb celebrates 20 years and Reish is an experimental UNIX-style shell implemented for Rubyists that translates shell syntax into Ruby AST and executes it; commands become Ruby methods, pipelines map to enumerator/message chaining, and job control runs background jobs as threads rather than forks so Ruby built‑ins behave correctly. It implements type‑aware completion and method‑based filtering for fewer candidates (type‑aware completion), multiline editing with a GNU‑readline replacement, and code generation heuristics; development is active, demos mostly work but some features remain flaky.
