doclayout

0.2

• Add instances for Doc: Data, Typeable, Ord, Read, Generic.
• Add literal (like text, but polymorphic).
• Change some IsString constraints to HasChars.
• Add some default definitions for methods in HasChars.
• Change offset and minOffset to be more efficient (in simple cases they no longer render and count line lengths).
• Add updateColumn.
• Fix problem with lblock/cblock/rblock when chop is invoked. This caused very strange behavior in which text got reversed in certain circumstances.

0.1

• Initial release.
