Functions

func RuneWidth

func RuneWidth(r rune) int

RuneWidth returns the number of cells needed to draw r. Background in http://www.unicode.org/reports/tr11/.

Treats runes used internally by termdash as single-cell (half-width) runes regardless of the locale. I.e. runes that are used to draw lines, boxes, indicate resize or text trimming was needed and runes used by the braille canvas.

This should be safe, since even in locales where these runes have ambiguous width, we still place all the character content around them so they should have be half-width.

func StringWidth

func StringWidth(s string) int

StringWidth is like RuneWidth, but returns the number of cells occupied by all the runes in the string.
