CodeSuite

VS Code-quality code blocks for Obsidian, powered by Shiki, the same syntax highlighting engine used by VS Code.

Works in both reading view and editor (live preview / source mode).

Features

Syntax Highlighting

• 65+ built-in themes: Gruvbox, Catppuccin, Dracula, Nord, Tokyo Night, One Dark Pro, GitHub, Material, and many more
• Import VS Code themes: load any .json color theme from VS Code
• Editor highlighting: full Shiki-powered tokens in live preview and source mode via a CM6 ViewPlugin
• 36 languages: Python, JS/TS, Rust, Go, C/C++, Java, Ruby, and more with common aliases (py, js, sh, etc.)
• Dynamic theme colors: code block chrome (headers, borders, output panels) automatically adapts to match the selected theme

Code Execution

• Run code from Obsidian: execute Python, JavaScript, TypeScript, Bash, Ruby, Go, Lua, Perl, PHP, R, and Swift directly from code blocks
• Live streaming output: stdout and stderr stream in real-time
• Smart stdin: input bar appears only when your code reads from stdin (detects input(), process.stdin, read, etc.)
• Matplotlib & Plotly support: graphs render inline as images
• Execution timeout: configurable auto-kill for runaway processes
• Custom interpreter paths: set Python virtualenvs, custom Node paths, extra environment variables

Embedded Code Files

• Render ![[file.py]] embeds as fully highlighted code blocks
• Collapsible by default: long files show collapsed with a line count; click to expand
• Copy & Run buttons on embedded files

UI

• Header bar with language label, Copy, and Run buttons
• Line numbers with hover highlight
• Wide code blocks option for more horizontal space
• Mobile-friendly responsive layout

Installation

From Obsidian Community Plugins

Status: Submitted for community review via the Obsidian plugin submission portal. Obsidian has moved from GitHub PRs to a dedicated submission site for new community plugins.

1. Open Settings → Community Plugins → Browse
2. Search for "CodeSuite"
3. Click Install, then Enable

Manual

1. Download main.js, manifest.json, and styles.css from the latest release
2. Create a folder code-suite in your vault's .obsidian/plugins/ directory
3. Place the three files inside it
4. Restart Obsidian and enable "CodeSuite" in Community Plugins

Build from Source

git clone https://github.com/felixleopold/obsidian-code-suite.git
cd obsidian-code-suite
npm install
npm run build

Output: dist/main.js

Configuration

All settings are in Settings → CodeSuite:

How It Works

• Reading view: A Markdown post-processor replaces <pre><code> blocks with Shiki-highlighted HTML, wrapped in a styled container with header bar and buttons.
• Editor (live preview / source): A CodeMirror 6 ViewPlugin scans the document for code fences, tokenizes them with Shiki, and applies inline Decoration.mark styles for each token.
• Code execution: Runs locally on your machine via child_process.spawn. No code is sent to any server. Output streams live over stdout/stderr pipes.
