Here are some extensions to the String class used by Locana. This includes and extends the AddLocanaSupport module so Symbols can be used as the :text or :value attribute of Locana objects based on the Lobject class.

This is the reverse of succ!.

Returns a new string based self with line feeds inserted at distance intervals without splitting any words.

• distance - the number of characters to wrap each line.
• allow_growth - if nil then, the line is wrapped at distance. If > 0 then, individual lines can extend this amount beyond distance if it is a better fit.
• min_distance - this keeps a line from getting too short. It is ignored if allow_growth = nil. If the last line is shorter than min_distance, then the string will be rewrapped using distance+1. The default is nil which will not rewrap the line.

Returns a new string based self with line feeds inserted at distance intervals without splitting any words such that the pixel width of each line is less than pixel_width.

• pixel_width - the number of pixels to wrap each line at.

Returns true if this string has been word wrapped. Used by the Leditbox box to efficiently rewrap lines as needed.

An indicator is added to the String to indicate it has been wrapped. This Sets the word wrapped flag to new_value for this string. Used by the Leditbox box to efficiently rewrap lines as needed.
