Changelog of @hackage/vty 4.7.3

4.7.0.0 * API changes: * Added Graphics.Vty.Image.crop: Ensure an image is no larger than the specified size. * Added Graphics.Vty.Image.pad: Ensure an image is no smaller than the specified size. * Added Graphics.Vty.Image.translate: Offset an image. * Thanks Ben Boeckel MathStuf@gmail.com for these features.

4.3.0.0

4.2.1.0 * 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 * API changes: * "getSize" has been removed. Use "terminal vty >>= display_bounds" where "vty" is an instance of the Vty data structure. * added a "terminal" field to the Vty data structure. Accesses the TerminalHandle associated with the Vty instance. * Graphics.Vty.Types has undergone a number of changes. Summary: * Partitioned into Graphics.Vty.Attributes for display attributes. Graphics.Vty.Image for image combinators. Graphics.Vty.Picture for final picture construction. * Graphics.Vty.Attributes: * "setFG" and "setBG" are now "with_fore_color" and "with_back_color" * All other "set.." equations similarly replaced. * "attr" is now "def_attr", short for "default display attributes" Also added a "current_attr" for "currently applied display attributes" * Graphics.Vty.Image: * "horzcat" is now "horiz_cat" * "vertcat" is now "vert_cat" * "renderBS" is now "utf8_bytestring" * "renderChar" is now "char" * "renderFill" is now "char_fill" * added a "utf8_string" and "string" (AKA "iso_10464_string") for UTF-8 encoded Strings and ISO-10464 encoded Strings. String literals in GHC have an ISO-10464 runtime representation. * Graphics.Vty.Picture: * exports Graphics.Vty.Image * "pic" is now "pic_for_image" * added API for setting background fill pattern. * 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.
