Overview

Package misc provides short helpers for ANSI colouring and numeric formatting

Package misc are just short snippets of functions

Constants

const (
	ErrPanic = iota
	MsgPanic
	ErrMsgPanic
	ErrFatal
	MsgFatal
	ErrMsgFatal
	ErrPrint
	MsgPrint
	ErrMsgPrint
)

const (
	Green     = "\033[92m%s\033[0m"
	Red       = "\033[91m%s\033[0m"
	Purple    = "\033[95m%s\033[0m"
	Yellow    = "\033[96m%s\033[0m"
	LightBlue = "\033[94m%s\033[0m"
)

Colour helpers

const Bold = "\033[1m%s\033[0m"

ANSI colour codes Bold text

const BoldRightSize = "\033[1m%*s\033[0m"

BoldRightSize formats a string right-aligned in a field of width w

const BoldSize = "\033[1m%-*s\033[0m"

BoldSize formats a string left-aligned in a field of width w

Functions

func AddToSlice

func AddToSlice(sl []string, str string) []string

AddToSlice adds a string to a slice if it doesn't already exists.

func Boldf

func Boldf(format string, args ...interface{}) string

Short wrappers that hide the underlying fmt call

func FormatFloat

func FormatFloat(num float64, prc int, trim bool) string

FormatFloat renders a float64 with a fixed precision If trim is true, trailing zeroes and a dangling decimal point are removed

Example:

FormatFloat(1.2300, 4, true) // "1.23" FormatFloat(1.2, 4, false) // "1.2000"

func Greenf

func Greenf(format string, args ...interface{}) string

func LightBluef

func LightBluef(format string, args ...interface{}) string

func Purplef

func Purplef(format string, args ...interface{}) string

func Redf

func Redf(format string, args ...interface{}) string

func RemoveFromSlice

func RemoveFromSlice(sl []string, str string) []string

RemoveFromSlice removes a string from a slice if it exists.

func ShowError

func ShowError(e error, msg string, errType ErrorType)

ShowError Displays errors depending on the type of error Error types: ErrPanic - display error and panic MsgPanic - display message and panic ErrMsgPanic - display error and message and panic ErrFatal - display error and exit MsgFatal - display message and exit ErrMsgFatal - display error and message and exit ErrPrint - display error MsgPrint - display message ErrMsgPrint - display error and message

func Yellowf

func Yellowf(format string, args ...interface{}) string

Types
