# doclayout
## 0.3
* Add foldlChar to signature of HasChars [API change].
* Use foldlChar in realLength. This avoids a stack overflow
we were getting with long strings in the previous version
(with foldrChar). See jgm/pandoc#6031.
* Replace isBlank with isBreakable and improved startsWithBlank.
Previously isBlank was used in the layout algorithm where
what we really wanted was isBreakable.
* Avoid unnecessary calculation in updateColumns.
* Replace a right fold with a strict left fold.
* Add strictness annotations in realLength and updateColumn.
## 0.2.0.1
* Made `realLength` smarter about combining characters.
If a string starts with a combining character, that character
takes up a width of 1; if the combining character occurs after
another character, it takes 0. See jgm/pandoc#5863.
* Improve `isBlank`, re-use in rendering code `for BreakingSpace`.
* Fixed incorrect `Text` width in renderig blocks.
## 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.
