go2linq is Go implementation of .NET's LINQ to Objects. (See also: Language Integrated Query, LINQ, Enumerable Class.)

v4 of go2linq is based on Go Iterators.

Installation

go get github.com/solsw/go2linq/v4

Examples

Examples of go2linq usage are in the Example... functions in test files (see Examples).

Quick and easy example:

package main

import (
	"fmt"

	"github.com/solsw/go2linq/v4"
)

func main() {
	filter, _ := go2linq.Where(
		go2linq.iterhelper.VarSeq(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
