linq

Implementation of LINQ queries on Golang

Goal

Simplify operations over slices and study of working of reflection

Queries

Supported queries:

• Where

Where

package main

import (
	"fmt"

	"github.com/saromanov/go-linq"
)

func main() {
	l, err := linq.New([]int{1, 4, 5, 8, 9})
	if err != nil {
		panic(err)
	}
	fmt.Println(l.Where(func(x int) bool {
		if x > 4 {
			return true
		}
		return false
	}).Result().([]int)
}

[5 8 9]

In this example: First, create a Linq object, then apply of the Where method with filter. Filter function should be go func(x int) bool{}. At the last step, showing of response with Result method

Select

Select method to modify the elements on array

package main

import (
	"fmt"

	"github.com/saromanov/go-linq"
)

type Data struct {
	Key   int
	Value int
}

func main() {
	l, err := linq.New([]Data{Data{
		Key:   1,
		Value: 2,
	},
		Data{
			Key:   3,
			Value: 5,
		},
	})
	if err != nil {
		panic(err)
	}
	fmt.Println(l.Select(func(x Data) int {
		return x.Key
	}).Result().([]int))

}```
