vty-ui v1.5.1 Release Notes
-
📦 Package changes:
- Added library dependency on "text" package.
- Added tests dependency on "random" package.
- Now the vty-ui-tests binary builds by default and can be turned off with the 'no-tests' flag.
- Increased the declared cabal version to 1.8.
- Moved the demo sources into demos/ and added vty-ui as dependency for each. This helps to avoid redundant library compilation for each demo program.
- Removed some dubious Darwin-specific cabal directives.
API changes:
- Modified all widget constructors and functions to use Text values where previously they used Strings.
- Renamed List.newStringList to newTextList.
- Added TextClip, a module which implements one- and two-dimensional text clipping. The implementation respects Unicode character width.
- Added TextZipper, a module which implements a two-dimensional text editor in zipper fash ion.
- Added a "Phys" newtype to express physical column values (as opposed to character indices). This is used in logical-to-physical conversions and computations which have to take account of character width.
- Exported Edit.applyEdit for applying generic text zipper transformations to Edit widgets.
Misc changes:
- Modified FormattedText widgets to take account of Unicode character widths so that wide characters are rendered properly. Also modified some widgets to use FormattedText instead of direct Vty rendering to take advantage of this feature.
- Refactored the Edit widget to use TextZipper and TextClip modules to properly account for character width. Edit widgets now support multi-column characters and show beginning-of-line and end-of-line indicators ("$") in cases where wide characters cannot be shown due to display clipping.
- Added some QuickCheck properties for TextClip and TextZipper.
Other notes:
- Deprecation notice: Text.Trans.Tokenize will either be removed entirely or severely refactored in a future release.
🐛 Bug fixes:
- Fixed bug in Text.Trans.Tokenize.wrapStream which prevented over-long words from being wrapped properly, as well as lines where short words followed over-long ones.
