Brick changelog

0.6.3

Bug fixes:

• List: the list now properly renders when the available height is not a multiple of the item height. Previously the list size would decrease relative to the available height. Now the list renders enough items to fill the space even if the top-most or bottom-most item is partially visible, which is the expected behavior.

0.6.2

Bug fixes:

• Editor: the 'editor' initial content parameter is now correctly split on newlines to ensure that the underlying editor zipper is initialized properly. (fixes #56; thanks @listx)

0.6.1

Package changes:

• Added lower bound for microlens >= 0.3.0.0 to fix build failure due to Field1 not being defined (thanks Markus Hauck)

Documentation changes:

• Updated user guide and README to link to and mention microlens instead of lens

Misc:

• Fixed a qualified import in the List demo to avoid ambiguity (thanks Alan Gilbert)

0.6

API changes:

• Brick now uses the microlens family of packages instead of lens. This version of brick also depends on vty 5.5.0, which was modified to use microlens instead of lens. This change shouldn't impact functionality but will greatly reduce build times.

0.5.1

Bug fixes:

• Fix negative cropping in hCenter, vCenter, and cropResultToContext (fixes #52)
• Remove unnecessary Eq constraint from listReplace (fixes #48; thanks sifmelcara)
• Mention Google Group in README

0.5

Functionality changes:

• Markup: make markup support multi-line strings (fixes #41)
• brick-edit-demo: support shift-tab to switch editors
• Core: improve box layout algorithm (when rendering boxes, track remaining space while rendering high-priority children to use successively more constrained primary dimensions)
• Core: make fixed padding take precedence over padded widgets (fixes #42) Prior to this commit, padding a widget meant that if there was room after rendering the widget, the specified amount of padding would be added. This meant that under tight layout constraints padding would disappear before a padded widget would. This is often a desirable outcome but it also led to unexpected behavior when adding padding to a widget that grows greedily: fixed padding would never show up because it was placed in a box adjacent to the widget in question, and boxes always render greedy children before fixed ones. As a result fixed padding would disappear under these conditions. Instead, in the case of fixed padding, since we often intend to guarantee that padding is present, all of the padding combinators have been modified so that when the padded widget is rendered with fixed padding in the amount V, the widget is given V fewer rows/columns when it is rendered so that the padding always has room.

0.4.1

Bug fixes:

• Fixed a bug in the 'visible' combinator: If the size of the visibility request was larger than the available space, then the rendering of a viewport was toggling between two states, one with aligning on the end of the visibility request, and another one aligning on the start. This commit fixes it so that a visibility request is always aligned on the start if not enough space is available. (thanks Thomas Strobel ts468@cam.ac.uk)

Behavior changes:

• Honor multiple 'visible' markers in a single viewport with preference on the innermost request (thanks Thomas Strobel ts468@cam.ac.uk)

0.4

API changes:

• Added Brick.Widgets.Core.unsafeLookupViewport to make certain kinds of custom widget implementations easier when viewport states are needed (thanks Markus Hauck markus1189@gmail.com)
• List: added listClear and listReverse functions (thanks Markus Hauck)
• List: Derive instances for Functor, Foldable, Traversable (thanks Markus Hauck)

Documentation changes:

• Hyperlink "Data.Text.Markup" inside Brick.Markup haddock (thanks Markus Hauck)
• Fix typo in 'Attribute Management' section of user guide (thanks Markus Hauck)

0.3.1

Bug fixes:

• EventM newtype again instances MonadIO (thanks Andrew Rademacher)

0.3

API changes:

• Made EventM a newtype instead of a type alias
• List: listReplace now takes the new selected index and no longer does element diffing

Package changes:

• Removed the dependency on the Diff package

Misc:

• Applied some hlint hints (thanks Markus Hauck markus1189@gmail.com)
• Fixed a typo in the README (thanks Markus Hauck markus1189@gmail.com)
• Improved the renderList documentation (thanks Profpatsch mail@profpatsch.de)
• Types: added an explicit import of Applicative for older GHCs

0.2.3

Bug fixes:

• Fixed viewport behavior when the image in a viewport reduces its size enough to render the viewport offsets invalid. Before, this behavior caused a crash during image croppin in vty; now the behavior is handled sanely (fixes #22; reported by Hans-Peter Deifel)

0.2.2

Demo changes:

• Improved the list demo by using characters instead of integers in the demo list and cleaned up item-adding code (thanks Jøhannes Lippmann code@schauderbasis.de)

0.2.1

Bug fixes:

• List:
  • Fixed size policy of lists so that rather than being Fixed/Fixed, they are Greedy/Greedy. This resolves issues that arise when the box layout widget renders a list widget alongside a Fixed/Fixed one. (Closes issue #17, thanks Karl Voelker)
• Scrolling:
  • vScrollPage actually scrolls vertically now rather than horizontally (Thanks Hans-Peter Deifel hpd@hpdeifel.de)

0.2

API changes:

• Added top-level Brick module that re-exports the most important modules in the library.
• List:
  • Now instead of passing the item-drawing function to the list state constructor, it is passed to renderList
  • renderList now takes the row height of the list's item widgets. The list item-drawing function must respect this in order for scrolling to work properly. This change made it possible to optimize the list so that it only draws widgets visible in the viewport rather than rendering all of the list's items (even the ones off-screen). But to do this we must be able to tell in advance how high each one is, so we require this parameter. In addition this change means that lists no longer support items of different heights.
  • The list now uses Data.Vector instead of [a] to store items; this permits efficient slicing so we can do the optimized rendering described above.
• The HandleEvent type class handleEvent method now runs in EventM. This permits event-handling code implemented in terms of HandleEvent to do get access to viewport state and to run IO code, making it just as powerful as code in the top-level EventM handler.
• Many types were moved from Brick.Widgets.Core and Brick.Main to Brick.Types, making the former module merely a home for Widget constructors and combinators.
• The IsString instance for Widget was removed; this might be reinstated later, but this package provides enough IsString instances that things can get confusing.
• EventM is now reader monad over the most recent rendering pass's viewport state, in addition to being a state monad over viewport requests for the renderer. Added the lookupViewport function to provide access to the most recent viewport state. Exported the Viewport type and lenses.
• Now that handleEvent is now an EventM action, composition with continue et al got a little messier when using lenses to update the application state. To help with this, there is now handleEventLensed.

Bugfixes:

• Lists now perform well with 10 items or a million (see above; fixes #7, thanks Simon Michael)
• Added more haddock notes to Brick.Widgets.Core about growth policies.
• Forced evaluation of render states to address a space leak in the renderer (fixes #14, thanks Sebastian Reuße seb@wirrsal.net)
• str: only reference string content that can be shown (eliminates a space leak, fixes #14, thanks Sebastian Reuße seb@wirrsal.net)

Misc:

• Added a makefile for the user guide.
• List: added support for Home and End keys (thanks Simon Michael)
• Viewports: when rendering viewports, scroll requests from EventM are processed before visibility requests from the rendering process; this reverses this previous order of operations but permits user-supplied event handlers to reset viewports when desired.

Package changes:

• Added deepseq dependency
