# Parallel

golang 协程并行库，可以指定并发数量，可以当做简单的队列使用

## 安装 - installation

```bash

go get github.com/qbhy/parallel

```

## 使用 - usage

1. 普通用法

    ```go

    package tests

    

    import (

        "errors"

        "fmt"

        "github.com/qbhy/parallel"

        "testing"

    )

    

    func TestParallel(t *testing.T) {

        // 最多 10 个协程同时运行

        p := parallel.NewParallel(10)

    

        p.Add(func() interface{} {

            return "执行了"

        })

        

        p.Add(func() interface{} {

            panic(errors.New("报错了"))

        })

    

        fmt.Println(p.Wait())

        //会输出 map[0:执行了 1:报错了]

    }

    ```

2. 简单的队列

    ```go

    package tests

    

    import (

        "fmt"

        "github.com/qbhy/parallel"

        "testing"

        "time"

    )

    

    // 测试优雅退出

    func TestParallelGracefulStop(t *testing.T) {

        p := parallel.NewParallel(2)

    

        go func() {

            i := 0

            for ; i < 10; i++ {

                (func(i int) {

                    if i >= 5 {

                        p.GracefulStop()

                    }

                    result := p.Add(func() interface{} {

                        time.Sleep(time.Second)

                        fmt.Printf("每隔1秒执行一次 %d \n", i)

                        return nil

                    })

    

                    fmt.Printf("添加结果: %v, i: %d\n", result, i)

                })(i)

            }

        }()

    

        fmt.Println(p.Listen())

    }

    ```
