myGoToolbox

myGoToolbox is a package which contains a collection of useful functions and handy tools for recurring tasks in your Go projects. myGoToolbox is aiming at as clear and clean Go code as possible, preferably to make use of built-in packages only and to import as reasonably maintained and simple packages only to reduce the impact of broken dependencies to a minimum.

Install

go get github.com/jagottsicher/myGoToolbox

Features

escapeStringRegex.go

EscapeStringRegex returns a string that escapes all regular expression metacharacters inside the argument of type string like .+*?()|[]{}^ and returns a string which is a regular expression matching the literal text.

func EscapeStringRegex(s string) string

Example:

package main

import (
	"fmt"

	"github.com/jagottsicher/myGoToolbox"
)

func main() {
	s := `How much $ for a 🦄?`

	fmt.Println(EscapeStringRegex(s))
	// Output:
	// How much \$ for a 🦄\?
}

terminal.go

Clearscreen() empties the terminal screen independently from the underlying operation system by calling the OS's built-in functions works smootly even on both Windows' cmd.exe and powershell.

Clearscreen()

thousands.go

thousands.go mainly consists of the function Separate() which adds thousands separators to numbers. It takes two arguments: the number and a language-code you want to use. It returns a string with thousands separators as commonly used in this lang/region. Actually Separate() supports English, German and French (intl. recommended) notation. More information about decimal separators.

English is default/fallback for wrong or missing language code. Feels free to open an issue and request more or other notations.

func Separate(N interface{}, lang string) (string, error)

Examples:

package main

import (
	"fmt"

	"github.com/jagottsicher/myGoToolbox"
)

func main() {
	n := 1232323.123456789
	output_en, _ := myGoToolbox.Separate(n, "en")
	output_de, _ := myGoToolbox.Separate(n, "de")
	output_fr, _ := myGoToolbox.Separate(n, "fr")

	fmt.Println(output_en)
	fmt.Println(output_de)
	fmt.Println(output_fr)
	// Output:
	// 1,232,323.123456789
	// 1.232.323,123456789
	// 1 232 323,123456789
