mdbook-langtabs

An mdBook preprocessor that creates language tabs for code examples.

Features

• Switch between language examples without scrolling
• Automatic language icons via Devicon
• Remembers selected language preference

Installation

cargo install mdbook-langtabs

Or install the current development version:

cargo install --git https://github.com/nx10/mdbook-langtabs

Setup

Either use the automatic installer:

mdbook-langtabs install /path/to/your/book

Or manually:

1. Add to your book.toml:

[preprocessor.langtabs]
command = "mdbook-langtabs"

[output.html]
additional-css = ["langtabs.css"]
additional-js = ["langtabs.js"]

2. Copy langtabs.css and langtabs.js to your book's root directory.

Usage

Wrap your code blocks with the special comments:

<!-- langtabs-start -->
```rust
fn main() {
    println!("Hello from Rust!");
}
```

```python
def main():
    print("Hello from Python!")
```

```javascript
function main() {
    console.log("Hello from JavaScript!");
}
```
<!-- langtabs-end -->

This creates tabbed code examples that readers can switch between, as shown in the demo above.
