confy

Structural tree editor for TOML / JSON / JSONC / YAML, embedding the confy web UI + wasm Session in a custom editor. Design: docs/superpowers/specs/2026-07-15-vscode-extension-design.md.

Install

• Marketplace: search confy in VS Code's Extensions view, or install wenanlin.confy-vscode.
• VSCodium / Cursor / Windsurf etc.: Open VSX listing.
• Sideload a built .vsix: code --install-extension confy-vscode-<version>.vsix (see Build).

Build

1. Build the web bundle first (repo root; esbuild must run from a scratchpad copy on this machine — see the plan/CLAUDE.md): crates/confy-ffi: wasm-pack build --target web, then web: node build.mjs
   • assemble web/dist (cf-build.sh's copy steps).
2. cd editors/vscode && npm install && npm run build (same scratchpad rule).
3. npm run package → confy-vscode-<version>.vsix.

Publishing a new version

1. Bump version in editors/vscode/package.json (normally done together with the app's own release version bump in the root chore: release vX.Y.Z commit).
2. Cut the app release as usual (git tag vX.Y.Z && git push --tags).
3. Once .github/workflows/release.yml succeeds, publish-gate.yml pauses for one manual approval (publish-gate environment), then dispatches .github/workflows/publish-vscode.yml with that tag — it checks out the tag, verifies package.json's version matches it, and publishes to the VS Marketplace + Open VSX (account/secret setup: VSCODE.md § Publishing).
4. A manual gh workflow run publish-vscode.yml -f tag=vX.Y.Z -f dry_run=true builds + packages without publishing — useful as a dry run.

Use

• Open a .toml/.json/.jsonc/.yaml/.yml file and click the Open with confy title-bar button (tree icon) — the tab swaps to confy in place, carrying any unsaved edit; inside confy, Reopen as Text Editor swaps back the same way. (Right-click → "Reopen Editor With…" → confy still works.) To make confy the default for a glob, use VS Code's workbench.editorAssociations setting (e.g. "*.toml": "confy.editor").
• confy: Open Text Editor to the Side (title-bar button next to Reopen as Text Editor, or command palette) — the real text editor, editable and live in both directions (shared TextDocument).
• Save/undo/redo/revert are native VS Code (⌘S / ⌘Z / ⌘⇧Z / File > Revert), backed by a shared TextDocument — switching editors carries unsaved changes, and side-by-side text editing syncs live in both directions.
• The confy toolbar header is hidden in this host — Save As / Convert…, Help, About, and the Language submenu live in the editor tab's "…" More Actions menu (command palette works too). ⇧⌘S (Ctrl-Shift-S) is the keyboard shortcut for Save As / Convert.
