Overview

Create & Generate text based table

Example (Autowrap) 
var multiline = `A multiline
string with some lines being really long.`

const (

)

		for _, autoWrap := range []bool{false, true} {
			for _, reflow := range []bool{false, true} {
				if !autoWrap && reflow {
					// Invalid configuration, skip
					continue

				fmt.Println("mode", mode, "autoFmt", autoFmt, "autoWrap", autoWrap, "reflow", reflow)
				t := NewWriter(os.Stdout)
				t.SetAutoFormatHeaders(autoFmt)

Functions

func ConditionString 

func ConditionString(cond bool, valid, inValid string) string

Simple Condition for string Returns value based on condition

func DisplayWidth 

func DisplayWidth(str string) int

func Pad 

func Pad(s, pad string, width int) string

Pad String Attempts to place string in the center

func PadLeft 

func PadLeft(s, pad string, width int) string

Pad String Left position This would place string at the right side of the screen

func PadRight 

func PadRight(s, pad string, width int) string

Pad String Right position This would place string at the left side of the screen

func Title 

func Title(name string) string

Format Table Header Replace _ , . and spaces

func WrapString 

func WrapString(s string, lim int) ([]string, int)

Wrap wraps s into a paragraph of lines of length lim, with minimal raggedness.

func WrapWords 

func WrapWords(words []string, spc, lim, pen int) [][]string

WrapWords is the low-level line-breaking algorithm, useful if you need more control over the details of the text wrapping process. For most uses, WrapString will be sufficient and more convenient.

WrapWords splits a list of words into lines with minimal "raggedness", treating each rune as one unit, accounting for spc units between adjacent words on each line, and attempting to limit lines to lim units. Raggedness is the total error over all lines, where error is the square of the difference of the length of the line and lim. Too-long lines (which only happen when a single word is longer than lim units) have pen penalty units added to the error.
