My Reasonix

A VSCode extension that brings the Reasonix kernel into your editor sidebar — multi-tab agent sessions, project-scoped workspaces, and inline interactions.

VSCode-specific Features

• Sidebar integration — Runs as an Activity Bar panel, side-by-side with your editor.
• Editor tab settings — Click the gear icon to open settings as a VSCode Editor Tab (gear icon included), draggable and pinnable.
• Workspace awareness — Tracks the current VSCode workspace folder. Switch projects — your session tabs follow.
• Lifecycle managed — The Go backend runs as a child process. Close VSCode — it cleans up. No manual start/stop.
• No silent failures — Every .catch(() => {}) replaced with full-stacktrace error logging.

Loading

• extension.ts — Spawns/kills the Go process, pushes workspace root and VSCode events to the frontend via postMessage.
• Frontend (iframe) — Gets VSCode info from the extension, Reasonix data from the Go backend. Orchestrates.
• Go Backend — No VSCode-specific code. Pure Reasonix kernel. Communicates over HTTP/SSE.

Development

# Build frontend
cd frontend
pnpm install && pnpm build

# Build Go backend
CGO_ENABLED=0 go build -o my-reasonix .

# Press F5 in VSCode to launch the Extension Host debug window

A pre-launch task build:all runs these steps automatically before F5.

Configuration

• MY_REASONIX_ADDR — backend listen address (default 127.0.0.1:18765)
• Uses standard reasonix.toml / ~/.reasonix/config.toml
