This is a ruby.wasm plugin for Obsidian (https://obsidian.md).

The plugin downloads the selected Ruby WebAssembly runtime from jsDelivr the first time you run a command so the shipped main.js stays small enough for Obsidian Sync.

Ruby versions

You can choose the runtime version in Settings -> Community plugins -> ruby.wasm.

Currently supported:

• Ruby HEAD
• Ruby 4.0
• Ruby 3.4
• Ruby 3.3
• Ruby 3.2

Features

• Run the selected Ruby code from the editor
• Run the whole current Ruby code block when nothing is selected
• Show stdout, stderr, return value, and errors separately
• Add a Run button under rendered ruby code blocks for a lightweight REPL flow
• Choose the Ruby runtime version from plugin settings
