Class methods

line(text : String, style : Style = Style::NONE) : StyledLine

A styled line from plain text.

Source

plain(line : StyledLine) : String

render(line : StyledLine, io : IO, color : Bool = true) : Nil

Source

to_ansi(line : StyledLine, color : Bool = true) : String

Source

truncate(line : StyledLine, width : Int32, ellipsis : String | Nil = nil) : StyledLine

Cuts a line to width columns, optionally with an ellipsis. Never splits a double-width character in half: if it does not fit, the cut happens one column earlier.

Source

width(line : StyledLine) : Int32

Source

wrap(line : StyledLine, width : Int32) : Array(StyledLine)

Greedy word wrap that keeps styles intact. Words longer than the width are hard-broken; spaces at a wrap point are dropped rather than trailing.
