Brick changelog
---------------
0.44.1
------
Bug fixes:
* `Brick.Markup` now properly renders empty lines in markup (#209)
0.44
----
API changes:
* The `List` type got its container type generalized thanks to a lot of
work by Fraser Tweedale. Note that this change is
backwards-compatible with older Brick programs that use the `List`.
Thanks to this work, the `List` now supports both `Data.Vector`
and `Data.Sequence` as its container types out of the box and can
be extended to support other sequence types with some simple type
class instances. In addition, property tests are provided for `List`
and its asymptotics are noted in the documentation. Along the way,
various bugs in some of the list movement functions got fixed to
bring them in line with the advertised behavior in the documentation.
Thanks, Fraser!
0.43
----
API changes:
* The FileBrowser module got the ability to select multiple files
(#204). This means that the `fileBrowserSelection` function now
returns a list of `FileInfo` rather than at most one via `Maybe`.
The module also now uses a new attribute, `fileBrowserSelectedAttr`,
to indicate entries that are currently selected (in addition to
displaying an asterisk after their filenames). Lastly, the file
size and type fields of `FileInfo` have been replaced with a
new type, `FileStatus`, and `FileInfo` now carries an `Either
IOException FileStatus`. As part of that safety improvement,
`setWorkingDirectory` now no longer clobbers the entire entry listing
if any of the listings fail to stat. In addition, the FileBrowser now
uses the correct file stat routines to deal with symbolic links.
Package changes:
* Added lower bound on `directory` (thanks Fraser Tweedale)
Test suite changes:
* Test suite now propagates success/failure to exit status (thanks
Fraser Tweedale)
0.42.1
------
Behavior changes:
* File browsers in search mode now terminate search mode when `Enter`
is pressed, resulting in better behavior.
0.42
----
New features:
* Added `Brick.Widgets.FileBrowser`, which provides a filesystem
browser for selecting files and directories. Read the Haddock
module documentation and see the included demo program,
`programs/FileBrowserDemo.hs`, for information on using the new
functionality.
0.41.5
------
Miscellaneous:
* `suspendAndResume` now empties the rendering cache when returning to
the rendering event loop. This ensures that the state returned by the
`IO` action is rendered completely rather than relying on potentially
stale cache entries.
0.41.4
------
API changes:
* Forms: added `setFormFocus` function to set focus for a form
* Added `NFData` instances for `AttrMap` and `Theme` types (thanks
Fraser Tweedale)
0.41.3
------
Bug fixes:
* Lists now draw correctly without crashing due to a vector slice
bounds check failure if their rendering area is too small (#195;
thanks @andrevdm)
Other changes:
* Relaxed base bounds to support GHC 8.6 (thanks @maoe)
* Added towerHanoi to the featured projects list
0.41.2
------
Bug fixes:
* Support STM 2.5 by allowing for `Natural` argument to `newTBQueue`
(thanks @osa1)
0.41.1
------
New features:
* `Forms`: added `checkboxCustomField` and `radioCustomField` to permit
customization of characters used to draw selection state for such
fields.
0.41
----
New features:
* `Brick.Forms` got a new field constructor, `listField`, that provides
a form field using a `List`.
* `List`: added the `listMoveToElement` function for changing the list
selection to the specified element, if it exists.
Package changes:
* Now depends on vty >= 5.24.
Other changes:
* `viewport`: fixed failable patterns for forward compatibility with
GHC 8.6 (#183)
* Add `Generic`, `NFData`, and `Read` instances for some types
0.40
----
New features:
* Brick.Widgets.Core: added new functions `hLimitPercent` and
`vLimitPercent`. These behave similarly to `hLimit` and `vLimit`
except that instead of taking absolute numbers of columns or rows,
they take percentages. (Thanks Roman Joost)
0.39
----
New features:
* The `italic` keyword is now supported in theme customization file
style lists. This requires `vty >= 5.23.1`
0.38
----
New features:
* Added support for parsing `#RRGGBB` color values in theme
customization files in addition to the color names already supported
(thanks Brent Carmer). These values are mapped to the nearest
reasonable entry in the 240-color space.
0.37.2
------
Bug fixes:
* Theme customization files can now use empty lists for style
customization.
0.37.1
------
API changes:
* Exposed `Brick.Forms.renderFormFieldState`.
0.37
----
Behavior changes:
* `listMoveBy` now automatically moves to the first or last position
in the list if called when the list is non-empty but has no selected
element (thanks Philip Kamenarsky)
API changes:
* Added `Brick.Widgets.List.renderListWithIndex` that passes
the index of each element to the item rendering function (thanks
liam@magicseaweed.com)
0.36.3
------
Bug fixes:
* Fixed a bug where mouse-up events in viewports were not translated
into the global coordinate space, unlike mouse-down events (#173)
0.36.2
------
API changes:
* The Forms API got two new functions, `setFormConcat` and
`setFieldConcat`, used for controlling the previously hard-coded
concatenation behavior of form fields. These are optional and both
concatentation settings default to their former hard-coded values,
`vBox` (#172).
0.36.1
------
Package changes:
* Raiseed upper bound to support GHC 8.4.2 (#171)
Other changes:
* Improved List accessor documentation (thanks liam <liam@magicseaweed.com>)
* Brick.Main now uses a Set instead a list to track invalidation
requests to avoid duplicates.
0.36
----
New features:
* Dynamic border support: adjacent widgets that use borders can make
those borders seamlessly connect to each other! Thanks
so much to Daniel Wagner for this feature! Please see
`programs/DynamicBorderDemo.hs` for a demonstraton. Also see the
"Joinable Borders" section of the User Guide.
0.35.1
------
* Conditionally depend on semigroups for GHC before 8
0.35
----
* Added support for GHC 8.4.
* Updated travis build to test on all 8.x releases (thanks Peter
Simons)
0.34.1
------
Bug fixes:
* Fixed a bug where the "reverseVideo" style could not be parsed in a
theme customization when it was all lowercase (thanks Yuriy Lazarev)
Documentation changes:
* Guide: added more complete example of creating a default theme
(thanks Mark Wales)
* Guide: added offset to Extent pattern matching (thanks Mark Wales)
0.34
----
API changes:
* Core: vLimit and hLimit now *bound* sizes rather than setting them.
This was the original intention of these combinators. The change in
behavior means that now `vLimit N` means that *at most* `N` rows will
be available; if the context has less, then the smaller constraint in
the context is used instead. Programs affected by this behavior will
be those that assume that `vLimit` doesn't do this, but that should
be very few or zero.
Other changes:
* Dialog: now arrow keys no longer wrap around available buttons but
stop at rightmost or leftmost button to avoid confusion when
attempting to tell which button is selected in two-button dialogs
(thanks to Karl Ostmo for this change)
Documentation changes:
* Updated Haddocks for str/txt in Core to mention tab character
considerations
0.33
----
API changes:
* Forms: added support for external validation of form fields using
`setFieldValid`. See the Haddock, User Guide, and FormDemo.hs for
details.
* Borders: removed all attribute names except `borderAttr` to simplify
border attribute assignment.
0.32.1
------
Bug fixes:
* Core: make all text wrap widgets Greedy horizontally
Miscellaneous:
* Dialog: clarify purpose in documentation (w.r.t. #149)
0.32
----
API changes:
* This release adds the new `Brick.Forms` module, which provides an API
for type-safe input forms with automatic rendering, event handling,
and state management! See the Haddock and the "Input Forms" section
of the Brick User Guide for information on this killer feature! Many
thanks to Kevin Quick for feedback on this new functionality.
0.31
----
Behavior changes:
* `viewport` now implicitly causes generation of mouse events for the
viewport when mouse mode is enabled. The mouse events are expressed
in the coordinate system of the contents of the viewport. The
consequence and intention of this change is to enable mouse event
reporting for editors when clicks occur outside the known text area.
0.30
----
API changes:
* `Brick.Focus`: added `focusSetCurrent` to make it easy to set the
focus of a focus ring
* `Brick.Main`: added a simple polymorphic `App` value, `simpleApp`
0.29.1
------
Bug fixes:
* Mixed-case color names like "brightBlue" can now be parsed in theme
customization files.
0.29
----
API changes:
* Added Ord instances for `Location` and `BrickEvent` (thanks Tom
Sydney Kerckhove)
* `Brick.AttrMap`: attribute name components are now exposed via the
`attrNameComponents` function. Also added a Read instance for
AttrName.
New features:
* This release adds user-customizable theme support. Please see the
"Attribute Themes" section of the User Guide for an introduction; see
the Haddock documentation for `Brick.Themes` for full details. Also,
see the new `programs/ThemeDemo.hs` for a working demonstration.
0.28
----
API changes:
* Brick.AttrMap.setDefault was renamed to setDefaultAttr.
* Added Brick.AttrMap.getDefaultAttr: get the default attribute from an
attribute map.
* Added Brick.Widgets.Core.modifyDefAttr to modify the default
attribute of the rendering context.
Other changes:
* Updated AttrDemo to show usage of modifyDefAttr.
0.27
----
API changes:
* Brick.Widgets.Core: added `hyperlink` combinator (thanks Getty Ritter
for hyperlinking support)
Other changes:
* Updated AttrDemo to show how to use hyperlinking
* README: Added `herms` to featured projects
0.26.1
------
* Fixed haddock for listHandleEventVi.
0.26
----
API changes:
* Added Brick.Widgets.List.handleListEventVi to add support for
vi-style movements to lists (thanks Richard Alex Hofer)
Other changes:
* Added ListViDemo.hs to demonstrate the Vi-style handler for lists
(thanks Richard Alex Hofer)
0.25
----
API changes:
* List: added page movement functions `listMoveByPages`,
`listMovePageUp`, and `listMovePageDown` (thanks Richard Alex Hofer)
Miscellaneous:
* Fixed a spelling mistake in the AttrMap haddock (thanks Edward Betts)
0.24.2
------
Miscellaneous:
* Minor documentation updates including a clarification for #135
0.24.1
------
Bug fixes:
* vBox/hBox: when there is leftover space and all elements are greedy,
spread it amongst the elements as evenly as possible instead of
assigning it all to the first element (fixes #133)
Package changes:
* Include Sam Tay's brick tutorial files in extra-doc-files
0.24
----
API changes:
* Added Brick.Widgets.Core.setAvailableSize to control rendering
context size in cases where the screen size is too constraining (e.g.
for a floating layer that might be bigger than the screen).
Documentation changes:
* Samuel Tay has contributed his wonderful Brick tutorial to this
package in docs/samtay-tutorial.md. Thank you!
0.23
----
API changes:
* getVtyHandle: always return a Vty handle rather than Maybe
(Previously, in appStartEvent you'd get Nothing because Vty had
not been initialized yet. This made various use cases impossible
to satisfy because appStartEvent is a natural place to get initial
terminal state from Vty. This change makes it so that a Vty handle is
always available, even in appStartEvent.)
* txtWrapWith: added missing haddock
0.22
----
API changes:
* Core: added txtWrapWith and strWrapWith functions to provide control
over wrapping behavior by specifying custom wrapping settings.
Other changes:
* Updated TextWrapDemo.hs to demonstrate customizing wrapping settings.
0.21
----
Package changes:
* Upgrade to word-wrap 0.2
Other changes:
* Brick.Types.Internal: improve mouse constructor haddock
* Add a basic fill demonstration program (FillDemo.hs)
0.20.1
------
Bug fixes:
* str: fixed an IsString constraint confusion on GHC 7.10.1
0.20
----
Package changes:
* Added a dependency on "word-wrap" for text-wrapping.
* Added a new TextWrapDemo demo program to illustrate text wrapping
support
API changes:
* Brick.Widgets.Core: added new functions txtWrap and strWrap to do
wrapping of long lines of text.
Miscellaneous:
* Guide: fixed event type (#126)
0.19
----
API changes:
* The editor content drawing function is now passed to renderEditor,
not the constructor, to improve separation of presentation and
representation concerns. The corresponding Editor drawing function
lens and accessor were removed.
0.18
----
Package changes:
* Added a dependency on data-clist.
API changes:
* Brick.Focus: removed the Functor instance for FocusRing.
* Brick.Focus: re-implemented FocusRing in terms of the circular list
data structure from data-clist. In addition, this change introduced
"focusRingModify", which permits the user to use the data-clist API
to directly manipulate the FocusRing's internals. This way brick
doesn't have to re-invent the wheel on the focus ring behavior.
0.17.2
------
Package changes:
* Added programs/ReadmeDemo.hs and featured its output and code in the
README to provide an early demonstration
Library changes:
* centerAbout now right- and bottom-pads its operand to behave
consistently with h/vCenter
0.17.1
------
Package changes:
* Use Extra-Doc-Files instead of Data-Files for documentation files
Bug fixes:
* List: correctly update selected index in listInsert
* Update example program in brick.cabal (thanks @timbod7)
0.17
----
Package changes:
* Updated to depend on Vty 5.15.
* Updated to remove dependency on data-default.
* Discontinued support for GHC versions prior to 7.10.1.
API changes:
* Removed Data.Default instances for AttrName, AttrMap, Result, and
BorderStyle (use Monoid instances instead where possible).
* Added defaultBorderStyle :: BorderStyle.
* Added emptyResult :: Result n.
0.16
----
This release includes a breaking API change:
* Brick now uses bounded channels (Brick.BChan.BChan) for event
communication rather than Control.Concurrent.Chan's unbounded channels
to improve memory consumption for programs with runaway event
production (thanks Joshua Chia)
Other API changes:
* Brick.List got a new function, listModify, for modifying the selected
element (thanks @diegospd)
Performance improvements:
* hBox and vBox now use the more efficient DList data structure when
rendering to improve performance for boxes with many elements (thanks
Mitsutoshi Aoe)
0.15.2
------
Bug fixes:
* viewport: do not cull cursor locations on empty viewport contents
(fixes #105)
* User guide CounterEvent type fix (thanks @diegospd)
0.15.1
------
Bug fixes:
* List: fixed empty list validation in listReplace (thanks Joshua Chia)
0.15
----
Demo changes:
* MouseDemo: add an editor and use mouse events to move the cursor
* MouseDemo: Enhance MouseDemo to show interaction between 'clickable'
and viewports (thanks Kevin Quick)
New features:
* Editors now report mouse click events
API changes:
* Rename TerminalLocation row/column fields to avoid commonplace name
clashes; rename row/column to locationRow/locationColumn (fixes #96)
Bug fixes:
* Core: make cropToContext also crop extents (fixes #101)
* viewport: if the sub-widget is not rendered, also cull all extents and
cursor locations
Documentation changes:
* User Guide updates: minor fixes, updates to content on custom widgets,
wide character support, and examples (thanks skapazzo@inventati.org,
Kevin Quick)
0.14
----
This release added support for wide characters. In particular, wide
characters can now be entered into the text editor widget and used in
'str' and 'txt' widgets.
0.13
----
API changes:
* Mouse mode is no longer enabled by default.
* customMain's event channel parameter is now optional
* FocusRing now provides a Functor instance (thanks Ian Jeffries)
0.12
----
This release primarily adds support for mouse interaction. For details,
see the Mouse Support section of the User Guide. This release also
includes breaking API changes for the App type. Here's a migration
guide:
* Event handlers now take "BrickEvent n e" instead of "e", where "e"
was the custom event type used before this change. To recover your
own custom events, pattern-match on "AppEvent"; to recover Vty input
events, pattern-match on "VtyEvent".
* appLiftVtyEvent went away and can just be removed from your App
record constructor.
* If you aren't using the custom event type or were just using Vty's
"Event" type as your App's event type, you can set your event type to
just "e" because you'll now be able to get Vty events regardless of
whether you use a custom event type.
API changes:
* Added the Widget combinator "clickable" to indicate that a widget
should generate mouse click events
* Added the Extent data type and the "reportExtent" widget combinator
to report the positions and sizes of widgets
* Rendering "Result" values now include reported extents and update
their offsets (adds "extents" field and "extentsL" lens)
* Added "lookupExtent", "findClickedExtents", and "clickedExtent" in
EventM to find extents and check them for mouse clicks
* Removed appLiftVtyEvent. Instead of wrapping Vty's events in your own
type, you now get a "BrickEvent" that always contains Vty events but
has the ability to embed *your* custom events. See the User Guide for
details.
* Added demo program MouseDemo.hs
* Added demo program ProgressBarDemo.hs (thanks Kevin Quick)
* Added mapAttrname, mapAttrNames, and overrideAttr functions (thanks
Kevin Quick)
* Make handleEventLensed polymorphic over event type to allow use with
custom events (thanks Kevin Quick)
* Added Ord constraint to some library startup functions
Bug fixes:
* Added Show instance for Editor, List (fixes #63)
Documentation changes:
* Updated documentation to use new "resource name" terminology to
reduce confusion and better explain the purpose of names.
* Updated user guide with sections on mouse support, the rendering
cache, resource names, paste mode, and extents
Package changes:
* Depend on Vty 5.11.3 to get mouse mode support
0.11
----
API changes:
* Added getVtyHandle in EventM for obtaining the current Vty context.
It returns Nothing when calling the appStartEvent handler but after
that a context is always available.
0.10
----
New features:
* Added a rendering cache. To use the rendering cache, use the 'cached'
widget combinator. This causes drawings of the specified widget to
re-use a cached rendering until the rendering cache is invalidated
with 'invalidateCacheEntry' or 'invalidateCache'. This change also
includes programs/CacheDemo.hs. This change introduced an Ord
constraint on the name type variable 'n'.
* Added setTop and setLeft for setting viewport offsets directly in
EventM.
* Dialog event handlers now support left and right arrow keys (thanks
Grégoire Charvet)
Library changes:
* On resizes brick now draws the application twice before handling the
resize event. This change makes it possible for event handlers to
get the latest viewport states on a resize rather than getting the
most recent (but stale) versions as before, at the cost of a second
redraw.
Bug fixes:
* We now use the most recent rendering state when setting up event handler
viewport data. This mostly won't matter to anyone except in cases
where a viewport name was expected to be in the viewport map but
wasn't due to using stale rendering state to set up EventM.
0.9
---
Package changes:
* Depend on text-zipper 0.7.1
API changes:
* The editor widget state value is now polymorphic over the type of
"string" value that can be edited, so you can now create editors over
Text values as well as Strings. This is a breaking change but it only
requires the addition of the string type variable to any uses of
Editor. (thanks Jason Dagit and Getty Ritter)
* Added some missing Eq and Show instances (thanks Grégoire Charvet)
New features:
* The editor now binds Control-U to delete to beginning of line (thanks
Hans-Peter Deifel)
Bug fixes:
* List: avoid runtime exception by ensuring item height is always at
least 1
0.8
---
API changes:
* Center: added layer-friendly centering functions centerLayer,
hCenterLayer, and vCenterLayer.
Functionality changes:
* Dialog now uses new layer-friendly centering functions. This makes it
possible to overlay a Dialog on top of your UI when you use a Dialog
rendering as a separate layer.
* Updated the LayerDemo to demonstrate a centered layer.
* The renderer now uses a default Vty Picture background
of spaces with the default attribute, rather than using
ClearBackground (the Vty default). This is to compensate for an
unexpected attribute behavior in Vty when ClearBackgrounds (see
https://github.com/coreyoconnor/vty/issues/95)
0.7
---
NOTE: this release includes many API changes. Please see the "Widget
Names" section of the Brick User Guide for details on the fundamentals!
API changes:
* The "Name" type was removed. In its place we now have a name type
variable ("n") attached to many types (including EventM,
CursorLocation, App, Editor, List, and FocusRing). This change makes
it possible to:
* Avoid runtime errors due to name typos
* Achieve compile-time guarantees about name matching and usage
* Force widget functions to be name-agnostic by being polymorphic
in their name type
* Clean up focus handling by making it possible to pattern-match
on cursor location names
* The EditDemo demonstration program was updated to use a FocusRing.
* Added the "Named" type class to Brick.Widgets.Core for types that
store names. This type class is used to streamline the Focus
interface; see Brick.Focus.withFocusRing and EditDemo.hs.
* The List and Editor types are now parameterized on names.
* The List widget is now focus-aware; its rendering function now takes
a boolean indicating whether it should be rendered with focus. The
List uses the following attributes now:
* When not focused, the cursor is rendered with listSelectedAttr.
* When focused, the cursor is rendered with listSelectedFocusedAttr.
* The Editor widget is now focus-aware; its rendering function now
takes a boolean indicating whether it should be rendered with focus.
The Editor uses the following attributes now:
* When not focused, the widget is rendered with editAttr.
* When focused, the widget is rendered with editFocusedAttr.
* The Dialog's name constructor parameter and lens were removed.
* The 'viewport' function was modified to raise a runtime exception if
the widget name it receives is used more than once during the
rendering of a single frame.
Miscellaneous:
* Many modules now use conditional imports to silence redundancy
warnings on GHCs with newer Preludes (e.g. including Monoid,
Foldable, Traversable, Applicative, etc.)
0.6.4
-----
Bug fixes:
* Add missing Functor instance for Next type (thanks Markus Hauck)
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
