Manta Code Blocks

Manta Code Blocks is an Obsidian Community plugin that turns run-* code fences into editable examples with inline output.

• Seven browser runtimes work without an account. Other languages use an optional local container companion or a named remote provider.
• Runtime adapters share one result contract. A failed provider is retried only when execution is known not to have started, so an unknown failure cannot run the same code twice.
• Version 0.7.10 supports 24 language fences through 10 adapters. The repository test suite covers adapter selection, parsing, UI state, and release metadata.

Version: 0.7.10 · Obsidian 1.13.0+ · Desktop and mobile. See release notes for shipped changes and the roadmap for work in progress and plans.

A six-second loop of the current browser UI, with real JavaScript execution. Timing is condensed.

Install and try

1. Open the existing Community entry in Obsidian.
2. Select Install, then Enable.
3. Paste this block in a note, switch to Reading view, and select Run:

```run-javascript
console.log("Hello from Obsidian!");
```

The result appears below the code. Edit the example and run again; Copy keeps your edited code, while Reset restores the original.

Seven browser fences work without an account or server. Other languages use an optional local companion or a named remote provider. Remote execution is enabled by default; disable it in settings to prevent remote submission.

Manual installation: download main.js, manifest.json, and styles.css from Releases into .obsidian/plugins/runnable-code-blocks/, then reload Obsidian.

Part of the Manta family

The plugins work independently and share ordinary Markdown and links: Manta Diagrams, Manta Graph, and Manta Calendar.
