Leveling Up Developer Tooling For The Modern Rails & Hotwire Era
summary
A concrete Language Server is built for Stimulus and Turbo, implemented in TypeScript + Acorn to parse controllers and provide parsed controller names, targets and methods. It ships autocomplete, autocomplete, diagnostics and quick fixes (e.g. underscore vs dash corrections), and a CLI lint package; initial prototype lands in a single-night commit and LSP 1.0 releases in early May with RubyMine support. Remaining work: robust ERB/HTML parsing across many Rails setups and deeper Turbo/partial cross-file diagnostics. Also available: hotdevtools browser extension showing frames and controls.
