WordWrap

This function splits a long string into a table of lines no longer than maxwidth.

[[{{{image}}}|link=|]]	Note: A line without any spaces in it will not break, meaning it may exceed maxwidth.

[[{{{image}}}|link=|]]	Tip: This function may lag if used too often. Consider only calling this function when any of the arguments change (such as the text, maxwidth, it's scale or font, etc.) and caching the result, rather than calling it onClientRender or similarly frequent events.

Syntax

table wordWrap( string text, float maxwidth, [float scale=1, mixed font="default", bool bColorCoded=false] )

Required Arguments

• text: The string to break into lines.
• maxwidth: The number of pixels of allowed length per line.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

• scale: The size of the text, as in dxGetTextWidth. Defaults to 1.
• font: Either a custom DX font element or the name of a built-in dx font, as in dxGetTextWidth. Defaults to "default".
• bColorCoded: Should color codes be excluded from the width? (false will include #rrggbb in the length calculations). Defaults to false.

            lines[line] = lines[line] or "" -- define the line if it doesnt exist

            if colorcoded then

                local x, y = string.find(rw, "%x%x%x%x%x%x#") -- and search for the first (last) occurance of a color code

            word = word + 1 -- moves onto the next word (in preparation for checking whether to start a new line (that is, if next word won't fit)
        until ((not words[word]) or dxGetTextWidth(lines[line].." "..words[word], scale, font, colorcoded) > maxwidth) -- jumps back to 'repeat' as soon as the code is out of words, or with a new word, it would overflow the maxwidth
    
        lines[line] = string.sub(lines[line], 1, -2) -- removes the final space from this line
        if colorcoded then
            lines[line] = string.gsub(lines[line], "#%x%x%x%x%x%x$", "") -- removes trailing colorcodes
        end
        line = line + 1 -- moves onto the next line
    end -- jumps back to 'while' the a next word exists
    return lines

text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum."
