Golang Concurrency Manager package limits the number of goroutines that are allowed to run concurrently.

### Installation

Run the following command to install this package:

```

$ go get -u github.com/zenthangplus/goccm

```

### Example

```go

package main

import (

    "fmt"

    "github.com/zenthangplus/goccm"

    "time"

)

func main() {

    // Limit 3 goroutines to run concurrently.

    c := goccm.New(3)

    for i := 1; i <= 10; i++ {

        // This function has to call before any goroutine

        c.Wait()

        go func(i int) {

            fmt.Printf("Job %d is running\n", i)

            time.Sleep(2 * time.Second)

            // This function has to when a goroutine has finished

            // Or you can use `defer c.Done()` at the top of goroutine.

            c.Done()

        }(i)

    }

    // This function has to call to ensure all goroutines have finished

    // after close the main program.

    c.WaitAllDone()

}

```

### List of supported functions

```go

package main

import "github.com/zenthangplus/goccm"

func main() {

    // Create the concurrency manager

    // The first argument is the maximum number of goroutines to run concurrently.

    c := goccm.New(10)

    // Wait until a slot is available for the new goroutine.

    c.Wait()

    // Mark a goroutine as finished

    c.Done()

    // Wait for all goroutines are done

    c.WaitAllDone()

    // Close the manager manually

    c.Close()

    // Returns the number of goroutines which are running

    c.RunningCount()

}

```
