Changelog of @hackage/reflex-vty 0.5.2.0

Revision history for reflex-vty

0.5.2.0

Update to use latest version of vty (for cross-platform support)
Fix an issue where the cursor tag is not used for an empty string in displayLineWithAlignment

0.5.1.0

Change inputInFocusedRegion to filter mouse scroll wheel input based on if the region under than the mouse rather than using mouse drag tracking
Add MonadCatch, MonadThrow, and MonadMask instances (relies on reflex-0.9.2.0 or greater)

0.5.0.0

Breaking change:
- scrollableText now takes a ScrollableConfiguration instead of just an Event t Int of lines to scroll by. Replacing a scrollableText myEvent invocation with scrollableText (def { _scrollableConfig_scrollBy = myEvent }) should recover the old behavior.
- scrollableText now returns a Scrollable t instead of a Behavior (Int, Int). The second Int, representing the total number of lines, is part of the Scrollable record. The first Int, representing the current scroll position is replaced by the ScrollPos in the Scrollable output. ScrollPos is a new type that captures whether a scrollableText is scrolled to the very top, very bottom, or somewhere in between.
scrollableText can now be given a starting scroll position and an event that scrolls it to a particular position.
scrollableText can be configured to remain scrolled to the bottom on new output, either always or whenever the user is scrolled to the bottom and new output appears.
Added a new scrollable widget in Reflex.Vty.Widget.Scroll that allows vertical scrolling when an Image is taller than the widget's height.
Add ctrlc, a convenience function that returns an event that fires when a Ctrl+c keypress is detected
Fix several issues with wide chars, cursor position and word wrapping in Zipper.hs
Add centerText function to Reflex.Vty.Widget.Box

0.4.1.1

Support ghc-9.6

0.4.1.0

Loosen version bounds and support GHC 9.4.4
Add MonadHold t (Performable m) and MonadFix (Performable m) instances to MonadVtyApp

0.4.0.0

Breaking Changes:
- Added mouse tracking to the behavior of pane such that
  - Mouse actions that start outside of the region are not tracked
  - Mouse drag sequences that start OFF the region are NOT reported
  - Mouse drag sequences that start ON the region and drag off ARE reported
  - Introduce MonadHold constraint to pane
- Added MonadHold constraint to several methods that use pane

0.3.1.1

Loosen version bounds and support GHC 9.4

0.3.1.0

Replace mempty with defAttr for Attr from Graphics.Vty to make it compatible with vty-5.34

0.3.0.0

Re-design textInput, TextInput and TextInputConfig.
- Allows users to implement more complex behavior.
- _textInputConfig_modify is now applied to the text-value of textInput after user input events such as mouse clicks and keyboard input. This may change the observable behavior.

0.2.0.1

Loosen version bounds on ref-tf and vty

0.2.0.0

Module Reorganization: The following modules have been added (and are all re-exported by Reflex.Vty):
- Reflex.Vty.Widget.Box for all the box functions and datatypes
- Reflex.Vty.Widget.Input.Mouse for clicking, dragging, and scrolling
- Reflex.Vty.Widget.Split contains splitV, splitH, etc
- Reflex.Vty.Widget.Text contains text rendering functions like text and display
Bugfixes:
- Remove text-icu dependency and switch to wcwidth from vty package to compute character width in Data.Text.Zipper.
- goToDisplayLinePosition in Data.Text.Zipper correctly accounts for character width now.
- #37 Layout should support focus changes through nested layouts (thanks @pdlla for getting this started -- see entry on Layout and Focus below).
- Fix distribution of available space when it cannot be evenly distributed. Previously, all leftover space would be allocated to the first stretchable widget.
Breaking Changes:
- Layout and focus have been substantially refactored to fix #37 and support a wider variety of layouts and focus switching requirements.
  - Added a new HasFocus class (the old one is now HasFocusReader) to produce focusable elements, and manage focus state. See the "Focus" section of the Reflex.Vty.Widget.Layout module documentation.
  - Layout no longer has any focus-tracking responsibility. See the "Layout" section of the Reflex.Vty.Widget.Layout module documentation.
  - tile no longer takes a configuration record and no longer requires that its child widget return a focus request event. Focus requests are instead handled using calls to requestFocus in the child widget.
  - Calls to fixed and stretch must now be replaced with tile . fixed and tile . stretch
  - stretch now takes a minimum size argument
  - Added flex which is equivalent to stretch 0
  - tabNavigation no longer returns an Event. Instead it calls requestFocus directly with the appropriate Refocus_Shift value.
  - Added axis (in HasLayout), a lower-level primitive which is used to implement row and col.
  - Added region (in HasLayout), which is used to claim screen real estate and used to implement tile and grout
  - Added grout, a container element that is not itself focusable (though its children can be)
- Removed VtyWidget and replaced it with a number of separate classes and monad transformers
  - Replace HasDisplaySize with HasDisplayRegion which carries around a region instead of just a width and height. displayWidth and displayHeight are now functions implemented in terms of askRegion instead of class methods.
  - Add a DisplayRegion monad transformer
  - Rename ImageWriter to HasImageWriter
  - Introduce an ImageWriter monad transformer
  - Rename HasFocus to HasFocusReader
  - Introduce a FocusReader monad transformer
  - Replace HasVtyInput with HasInput
  - Introduce an Input monad transformer
  - Introduce HasTheme reader class to allow setting Vty attributes of all built-in widgets
  - Introduce ThemeReader monad transformer
- Remove DynRegion and currentRegion. Use Dynamic t Region and current instead. This also changes the type of pane's argument.
- CheckboxConfig now has a field taking an Event to set the value of the checkbox.
- checkbox now accepts keyboard input (spacebar to check and uncheck) and is displayed in bold when focused.
- HasInput (formerly HasVtyInput) now has a method localInput for filtering the input a child widget may receive
- HasImageWriter now has a method mapImages for transforming the images emitted by a child widget
- boxTitle now takes a Behavior t Text as its title, instead of a plain Text
- fill now takes a Behavior t Char instead of a Char
- The following functions are no longer specialized to VtyWidget:
  - pane: Now requires HasInput t m, HasImageWriter t m, HasDisplayRegion t m, HasFocusReader t m
  - drag: Now requires HasInput
  - mouseDown: Now requires HasInput
  - mouseUp: Now requires HasInput

  - splitVDrag: Now requires HasDisplayRegion t m, HasInput t m, HasImageWriter t m, HasFocusReader t m
  - fill: Now requires HasImageWriter and HasDisplayRegion
  - boxTitle: Now requires HasDisplayRegion t m, HasImageWriter t m, HasInput t m, HasFocusReader t m, HasTheme t m
  - box: Now requires HasDisplayRegion t m, HasImageWriter t m, HasInput t m, HasFocusReader t m, HasTheme t m
  - boxStatic: Now requires HasDisplayRegion t m, HasImageWriter t m, HasInput t m, HasFocusReader t m, HasTheme t m
  - richText: Now requires HasImageWriter, and HasDisplayRegion
  - scrollableText: Now requires HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - blank: Now requires Monad
  - button: Now requires HasFocusReader, HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - textButton: Now requires HasFocusReader, HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - textButtonStatic: Now requires HasFocusReader, HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - link: Now requires HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - checkbox: Now requires HasFocusReader, HasInput, HasImageWriter, and HasDisplayRegion
- TextZipper interface changes
  - _displayLines_offsetMap type changed to OffsetMapWithAlignment
  - _displayLines_cursorY replaced with _displayLines_cursorPos which include X position
  - some exposed methods intended for internal use only have been removed
  - textInput: Now requires HasFocusReader, HasInput, HasImageWriter, HasTheme, and HasDisplayRegion
  - multilineTextInput: Now requires HasFocusReader, HasInput, HasImageWriter, HasTheme, and HasDisplayRegion

Misc:
