Development

Prerequisites

• Node.js >= 18
• Yarn

Setup

Build

yarn compile       # TypeScript compilation (one-shot)
yarn watch         # TypeScript compilation (watch mode)
yarn esbuild       # Bundle with esbuild + sourcemaps
yarn esbuild-watch # Bundle in watch mode

Format & Lint

Developer notes

• The extension now applies rule-based edits in a safer batch mode and shows success/failure feedback.
• The Ask RepoLens quick pick flow is hardened to handle empty or cancelled input gracefully.
• Rule search webview markup and DOM handling were fixed to prevent broken element selection.
• Language server configuration sync is centralized through getRepoLensConfig() and updates on config changes.
• Added a new walkthrough step for line suggestions and passive code-quality guidance.
