Installation

You can download the package using

go get github.com/amalfra/recorder/v3

Usage

Next, import the package

import (
  "github.com/amalfra/recorder/v3"
)

You can record output from both Stdout as well as Stderr. The recorded output will be available as string. The following two structs are available for your use:

• recorder.Stdout - Can be used for recording from Stdout
• recorder.Stderr - Can be used for recording from Stderr

There are four struct methods which can be used to control recording process:

• Start - To start recording
• Stop - To stop recording
• GetOutput - To return recorded output as string
• ClearOutput - To clear the recorded output

To record follow below steps:

1. first create the instance of struct as follows:

rec := new(recorder.Stdout)

or if to record from Stderr do

rec := new(recorder.Stderr)

2. Now call the Start method as follows:

rec.Start()

From now onwards all Stdout or Stderr output will be captured.

3. Call Stop method as follows when you want to stop recording process:

rec.Stop()

4. Now get the recorded output by calling the GetOutput method. It will return the recorded output string

out := rec.GetOutput()
