Custom tool

To support custom scenario, you can provide a compile function and wire it up as you please.

In this example, we use cowsay to create silly looking cows.

./docusaurus.config.js

const { say } = require("cowsay")

...
    compileCode: {
        langs: [
        ...,
        {
            lang: "cowsay",
            compile: async (text, langOptions) => ({
                stdout: say({ text })
            })
        }
    ]}

Let's take a look at this example in action.

```cowsay
hello
```

When rendered in the docs, this snippet looks like any other code snippe. But you'll also notice an additional box underneath with the capitalized text.

http://localhost:3000

hello

Output

 _______
< hello >

        \   ^__^
         \  (oo)\_______
