nettw

Small network-oriented Go library.

Installation

go get github.com/dector/nettw

Usage

Get available port (preferebly user-specified)

Use ParsePortOrPickAnother():

package main

import (
    "fmt"
    "github.com/dector/nettw"
)

func main() {
    port, err := nettw.ParsePortOrPickAnother("8080")
    if err != nil {
        panic(err)
    }

    // If port 8080 free - we will get it here.
    // If not - random free port will be returned.
    fmt.Printf("Using port: %d\n", port.Int)
}

Getting a Port with Custom Arguments

Use ParsePortOrPickAnotherWithArgs():

package main

import (
    "fmt"
    "github.com/dector/nettw"
)

func main() {
    port, err := nettw.ParsePortOrPickAnotherWithArgs(
        "8080",
        nettw.ParsePortArgs{
            NewPortFrom:       3000,
            NewPortTo:         4000,
            MaxTries:          50,
        }
    )
    if err != nil {
        panic(err)
    }

    fmt.Printf("Using port: %d\n", port.Int)
}
