* API changes:
|
|
* Attr record accessor fore_color changed to attr_fore_color
|
|
* Attr record accessor back_color changed to attr_back_color
|
|
* Attr record accessor style changed to attr_style
|
|
* Added an "inline" display attribute changing DSL:
|
|
* put_attr_change applies a display attribute change immediately to a terminal
|
|
* For instance, can be used to change the display attrbiutes of text output via putStrLn
|
|
and putStr. EX: "put_attr_change $ back_color red" will set the
|
|
background color to red.
|
|
* Changes do not apply to a Picture output via output_picture.
|
|
* See Graphics.Vty.Inline
|
|
* Moved all IO actions into any monad an instance of MonadIO
|
|
|
|
4.0.0.1
|
|
* binding for mk_wcswidth was incorrect. Most platforms just magically worked due to
|
|
coincidence.
|
|
|
|
4.0.0
|
|
* Completely rewritten output backend.
|
|
* Efficient, scanline style output span generator. Has not been fully optimized, but good
|
|
enough.
|
|
* The details required to display the desired picture on a terminal are well encapsulated.
|
|
* Terminfo based display terminal implementation. With specialized derivitives for xterm,
|
|
Terminal.app, and iTerm.app.
|
|
* Attempts to robustly handle even terminals that don't support all display attributes.
|
|
* I've tested the following terminals with success: iTerm.app, Terminal.app, xterm,
|
|
rxvt, mlterm, Eterm, gnome-terminal, konsole, screen, linux vty. Hopefully you will be
|
|
as successfull.
|
|
* Improved unicode support. Double wide characters will display as expected.
|
|
* 256 color support. See Graphics.Vty.Attributes.Color240. The actual output color is adjusted
|
|
according to the number of colors the terminal supports.
|
|
* The Graphics.Vty.Image combinators no longer require matching dimensions to arguments.
|
|
Unspecified areas are filled in with a user-customizable background pattern. See
|
|
Graphics.Vty.Picture.
|
|
* output images are always cropped to display size.
|
|
* Significant code coverage by QuickCheck tests. An interactive test for those final properties
|
|
that couldn't be automatically verified.
|
|
|
|
issues resolved:
|
|
* "gnome terminal displays non-basic attributes as strikethrough"
|

|
* "Multi-byte characters are not displayed correctly on update"
|
|
* http://trac.haskell.org/vty/ticket/10
|
|
* "Redraw does not handle rendering a line that extends beyond screen width characters"
|
|
* http://trac.haskell.org/vty/ticket/13
|
|
* "The <|> and <-> combinators should be more forgiving of mismatched dimensions"
|
|
* http://trac.haskell.org/vty/ticket/9
|
|
* "256-color support"
|
|
* http://trac.haskell.org/vty/ticket/19
