# sun

Sun is a Starlark module which adds Python-compatible built-ins like [`map`](https://docs.python.org/3/library/functions.html#map) and [`filter`](https://docs.python.org/3/library/functions.html#filter).

## Installation

```bash

go get github.com/tdakkota/sun

```

## Usage

```go

package main

import (

	"fmt"

	"go.starlark.net/starlark"

	"github.com/tdakkota/sun"

)

func main() {

	code := "list(filter(lambda x: x % 2 == 0, range(10)))"

	// Eval Starlark expresion.

	thread := &starlark.Thread{Name: "main"}

	result, err := starlark.Eval(thread, "example.star", code, sun.Module.Members)

	if err != nil {

		panic(err)

	}

	fmt.Println(result)

	// Output:

	// [0, 2, 4, 6, 8]

}

```
