# go2linq

[![Go Reference](https://pkg.go.dev/badge/github.com/solsw/go2linq.svg)](https://pkg.go.dev/github.com/solsw/go2linq/v4)

**go2linq v4** is Go implementation of .NET's 

[LINQ to Objects](https://learn.microsoft.com/dotnet/csharp/programming-guide/concepts/linq/linq-to-objects).

(See also: [Language Integrated Query](https://en.wikipedia.org/wiki/Language_Integrated_Query),

[LINQ](https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/linq/),

[Enumerable Class](https://learn.microsoft.com/dotnet/api/system.linq.enumerable).)

**go2linq v4** is based on [iter.Seq](https://go.dev/wiki/RangefuncExperiment), so it requires setting *GOEXPERIMENT=rangefunc* when executing **go** commands.

---

## Installation

```

go get github.com/solsw/go2linq/v4

```

## Examples

Examples of **go2linq** usage are in the `Example...` functions in test files

(see [Examples](https://pkg.go.dev/github.com/solsw/go2linq/v4#pkg-examples)).

### Quick and easy example:

```go

package main

import (

	"fmt"

	"github.com/solsw/go2linq/v4"

)

func main() {

	filter, _ := go2linq.Where(

		go2linq.VarAll(1, 2, 3, 4, 5, 6, 7, 8),

		func(i int) bool { return i > 6 || i%2 == 0 },

	)

	squares, _ := go2linq.Select(

		filter,

		func(i int) string { return fmt.Sprintf("%d: %d", i, i*i) },

	)

	for square := range squares {

		fmt.Println(square)

	}

}

```

The previous code outputs the following:

```

2: 4

4: 16

6: 36

7: 49

8: 64

```
