# xk6-interpret

This is a [k6](https://go.k6.io/k6) extension using the [xk6](https://github.com/grafana/xk6) system.

| :exclamation: This is a TOY extension. USE AT YOUR OWN RISK! OR... DON'T USE IT! |

|------|

## Build

To build a `k6` binary with this extension, first ensure you have the prerequisites:

- [Go toolchain](https://go101.org/article/go-toolchain.html)

- Git

Then:

1. Install `xk6`:

  ```shell

  $ go install go.k6.io/xk6/cmd/xk6@latest

  ```

2. Build the binary:

  ```shell

  $ xk6 build --with github.com/dgzlopes/xk6-interpret@latest

  ```

## Example

```javascript

import interpret from 'k6/x/interpret';

export default function() {

    var result = interpret.run(

    `package interpret

    

    import "fmt"

    // fibonacci is a function that returns

    // a function that returns an int.

    func fibonacci() func() int {

        x, y := 0, 1

        return func() int {

            x, y = y, x + y

            fmt.Println("Calculated:",x)

            return x

        }

    }

    func Run(s interface{}) interface{} {

        f := fibonacci()

        var results []int

        var i int64

        for i = 0; i < s.(int64); i++ {

            results = append(results,f())

        }

        return results

    }

    `,

    10

    );

    console.log(`Results: ${result}`)

}

```

Result output:

```

$ ./k6 run script.js
