Functions

func Escape 

func Escape(text string) string

Escape escapes the given text such that color and/or region tags are not recognized and substituted by the print functions of this package. For example, to include a tag-like string in a box title or in a TextView: 

box.SetTitle(tview.Escape("[squarebrackets]"))
fmt.Fprint(textView, tview.Escape(`["quoted"]`))

func Print 

func Print(screen tcell.Screen, text string, x, y, maxWidth, align int, color tcell.Color) (int, int)

Print prints text onto the screen into the given box at (x,y,maxWidth,1), not exceeding that box. "align" is one of AlignLeft, AlignCenter, or AlignRight. The screen's background color will not be changed.

You can change the colors and text styles mid-text by inserting a color tag. See the package description for details.

Returns the number of actual bytes of the text printed (including color tags) and the actual width used for the printed runes.

func PrintSimple 

func PrintSimple(screen tcell.Screen, text string, x, y int)

PrintSimple prints white text to the screen at the given position.

func TaggedStringWidth 

func TaggedStringWidth(text string) int

TaggedStringWidth returns the width of the given string needed to print it on screen. The text may contain color tags which are not counted.

func WordWrap 

func WordWrap(text string, width int) (lines []string)

WordWrap splits a text such that each resulting line does not exceed the given screen width. Possible split points are after any punctuation or whitespace. Whitespace after split points will be dropped.

This function considers color tags to have no width.

Text is always split at newline characters ('\n').
