# Command pipeline

CommandPipeline is a lightweight high performance pipeline (using "concurrency" to execute the commands) for Go.

## Usage

This is just a quick introduction

Let's start with a trivial Hello World example:

```go

    package main

    import (

        "github.com/donutloop/command-pipeline"

        "bytes"

    )

    func main() {

	    buildCommand := func(letter string) func(input *bytes.Buffer) (*bytes.Buffer, error) {

        		return func(input *bytes.Buffer) (*bytes.Buffer, error) {

        

        			input.WriteString(letter)

        

        			return input, nil

        		}

        	}

        

        	firstInput := bytes.NewBufferString("H")

        

        	pipeline := command_pipeline.New(

        		firstInput,

        		buildCommand("E"),

        		buildCommand("L"),

        		buildCommand("L"),

        		buildCommand("O"),

        		buildCommand(" "),

        		buildCommand("W"),

        		buildCommand("O"),

        		buildCommand("R"),

        		buildCommand("L"),

        		buildCommand("D"),

        	)

        

        	data, _ := pipeline.Execute()

        

        	print(data.String()) //Output: HELLO WORLD

    }

```
