README

WLog Build Status Go Report Card codecov

Package wlog creates simple to use UI structure. The UI is used to simply print to the screen. There a wrappers that will wrap each other to create a good looking UI. You can add color and prefixes as well as make it thread safe.

Idea Behind WLog

I used Mitchellh's CLI structure and wrapping for the different structures. It was a clean look and feel. Plus it was pretty simple to use. But I didn't want all the other cli stuff that came with the package so I created this.

For color I use DavidDenGCN's Go-ColorText. His color package allows for color that is available cross-platforms. I made a wrapper with all possible color combinations with his package. So you only have to import this package (one less line).

Example

var ui UI
reader := strings.NewReader("User Input\r\n") //Simulate user typing "User Input" then pressing [enter] when reading from os.Stdin
ui = New(reader, os.Stdout, os.Stdout)
ui = AddPrefix("?", Cross, " ", "", "", "~", Check, "!", ui)
ui = AddConcurrent(ui)

ui.Ask("Ask question", "")
ui.Error("Error message")
ui.Info("Info message")
ui.Output("Output message")
ui.Running("Running message")
ui.Success("Success message")
ui.Warn("Warning message")

Output:

? Ask question
✗ Error message
 Info message
Output message
~ Running message
✓ Success message
! Warning message

On Windows it outputs to this (this includes color):

winss

On Mac it outputs to this (this includes color):

macss
