code-editor

code-editor

Gives an agent read-only access to files in /workspace. It also opens files on its own when another app announces them, with no one telling it to: the working example of apps cooperating over the context bus.

Run it

cd apps/code-editor
berth dev
berth test

berth is the CLI: npm install -g @berthos/cli, or node ../../packages/cli/bin/berth.js from a clone.

To see the reactive path, run it with filesystem in the same sandbox and write a file:

berth dev --apps=apps/filesystem
berth rpc filesystem --container berth-dev-code-editor --export write_file --input '{"path":"hello.txt","content":"hi"}'

code-editor's log then shows it opening hello.txt. --apps paths are relative to the repo root; see multi-app sandboxes.

Capabilities

capabilities:
  - filesystem:read:/workspace

Read-only. The app can't write anywhere.

Exports

Export	Input	Output	What it does
open_file	{ path }	{ content }	Reads a file under /workspace

Reacting to other apps

When it starts, the app subscribes to fs.file_created. filesystem publishes that event on every write_file, and code-editor opens the new file in response:

filesystem --publish("fs.file_created", { path, createdBy })--> context bus --> code-editor

See the context bus reference.

Limits

• A subscriber only sees events published after it subscribed. There is no replay.
