Gonsole

Gonsole provides some simple operations which improve the ux inside the console

Prerequisites

This project makes use of go 1.18 which is currently in beta so make sure your project is set up properly

Install

Run go get github.com/MangioneAndrea/Gonsole to get the package

Usage

Console

The console is fairly simple to use.

• The first parameter is the message to print
• The second parameter is a flag to put before the message (optional)
• The third parameter is a filter function. It allows to print the message conditionally (optional)

Colors

package main

import "github.com/MangioneAndrea/gonsole"

func main() {
	gonsole.Error("File not found", "Error")
	gonsole.Log("Simple message", "Log")
	gonsole.Warn("Wrong password", "Warning")
	gonsole.Success("Action successful", "Success")
}

Conditions

package main

import (
	"github.com/MangioneAndrea/gonsole"
	"os"
)

// ShowIfNotEmpty user defined conditional for the console to show
var ShowIfNotEmpty gonsole.ShowIf = func(elem interface{}) bool {
	return elem != ""
}

func main() {
	// this file is in the same folder as the runnable
	data, err := os.ReadFile("./examples/console/condition/example.txt")
	gonsole.Error(err, "Error", gonsole.ShowIfNotNil)
	gonsole.Success(string(data), "Data", ShowIfNotEmpty)
	// This file does not exist
	data, err = os.ReadFile("./path/to/nowhere.go")
	gonsole.Error(err, "Error", gonsole.ShowIfNotNil)
	gonsole.Success(string(data), "Data", ShowIfNotEmpty)
}

CLI

The cli is a bit advanced and can be used mostly for small scripts. Each stage has a pointer as last parameter. The result is stored there

package main

import "github.com/MangioneAndrea/gonsole"

func main() {
	var name string
	var choco bool
	var color string
	var languages []string

	gonsole.Cli().
		Input("What's your name?", &name).
		Confirm("Do you like chocolate?", &choco).
		SelectOne("What's your favourite colour?", []string{"red", "blue", "yellow", "cyan"}, &color).
		SelectMany("What languages do you speak?", []string{"English", "German", "Italian", "French"}, &languages)
}
