4.1.1

Improvements

• Add pollingLabelWithVariableDelayAndRefresh. The WttrIn widget uses this.

Breaking Changes

• Use version-named package build dependencies. Users building their configurations with Stack or Nix may need to do likewise. That is, change:

  • gi-gtk → gi-gtk3
  • gi-gdk → gi-gdk3
  • gi-gdkx11 → gi-gdkx113

• Taffybar is tested with GHC versions 9.8 and 9.10. Other versions may or may not work.

4.1.0

Breaking Changes

• The BroadcastChan dependency has not received Cabal revisions for a while, so is replaced with Control.Concurrent.STM.TChan. Some types in System.Taffybar.Hooks and System.Taffybar.Information.{Battery,Chrome,Crypto} change accordingly.

Improvements

• Add icon next to window label in Windows widget. This can be configured with WindowsConfig(getActiveWindowIconPixbuf).

• Taffybar now watches its CSS files with inotify. Changes to CSS should be visible immediately after saving the file.

  If Taffybar is not running in a terminal, and the process receives a SIGHUP signal, then it will restart the inotify instance and reload the CSS files.

4.0.3

Breaking Changes

• Taffybar is tested with GHC versions >= 9.2 && < 9.10. Other versions may or may not work.

• The following symbols have been deprecated (not removed):

  • System.Taffybar.SimpleConfig.toTaffyConfig - Use toTaffybarConfig instead.
  • System.Taffybar.Support.PagerHints - Use the XMonad.Hooks.TaffybarPagerHints module instead.
  • System.Taffybar.Util:
    • liftReader - Use Control.Monad.Trans.Reader.mapReaderT instead.
    • logPrintFDebug - Use logPrintF instead.
    • (??) - Use f <*> pure a instead.
    • runCommandFromPath - Use runCommand instead.

Improvements

• Revise and expand documentation.

• Some code cleanups such as applying HLint suggestions, fixing compiler warnings, cleaning module imports.

• The Nix code for flake.nix was streamlined, because upstream nixpkgs already contains the necessary derivation overrides.

Bug Fixes

• Fix handling of Ctrl-C.

• Improve logging in System.Taffybar.Information.Battery and System.Taffybar.WindowIcon.

4.0.2

• Taffybar can now build with GHC 9.6.

• Allow building with Scotty 0.22.

• Drop unused ConfigFile dependency.

4.0.1

Improvements

• Taffybar can now build with GHC 9.4.

• Adds a flake.nix.

Bug Fixes

• Gtk.widgetShowAll is run on the widget created by cryptoPriceLabelWithIcon, so that it shows up by default.

• Fix misleading precision of rgba() parameters in taffybar.css.

• Remove cryptocurrency Cabal flag, which is now unnecessary.

4.0.0

Breaking Changes

• simpleTaffybar now starts taffybar using startTaffybar instead of dyreTaffybar. Use simpleDyreTaffybar to start taffybar with dyreTaffybar as before.

• The cssPath fields in ‘SimpleTaffyConfig’ and ‘TaffybarConfig’ have been renamed to cssPaths and have type [FilePath] instead of Maybe Filepath.

• The module System.Taffybar.Widget.Decorators has been removed. The functions that were in that module can now be found in System.Taffybar.Widget.Util.

• The barHeight property of SimpleTaffyConfig is now a StrutSize. This means that in addition to specifying an exact pixel count for the height of taffybar, it is also possible to specify a fraction of the screen that it should occupy. See the docs for StrutSize for more details.

New Features

• A new module System.Taffybar.Widget.Crypto that contains widgets that display the prices of crypto assets with icons was added.

• textBatteryNewLabelAction provides a version of the text battery widget to which a custom label updater function can be provided.

• The textual battery widget now applies classes according to its charge level that can be used to style the battery text with css.

• A generalized interface to the text battery widget that accepts an arbitrary update function is available at textBatteryNewLabelAction.

• New workspace widget builder buildLabelOverlayController that overlays the workspace label on top of the the workspace icons.

• It is now possible to customize the player widgets of the MPRIS2 Widget by using the new function mpris2NewWithConfig.

• Classes are added to the MPRIS2 Widget to indicate whether or not it has visible player children.

• The default MPRIS2 player widget now sends the play pause message to the relevant player when clicked.

• New pollingGraphNewWithTooltip that allows to specify a tooltip.

• New networkGraphNewWith that allows to configure a tooltip format, scaling and network interfaces via function.

• New showMemoryInfo exposed from MemoryMonitor that can be used to format tooltips.

• Swap variables are added to MemoryMonitor.

• Many types have Default instances.

• Window titles are shown on hover.

• Allow sorting workspace window icons by _NET_CLIENT_LIST_STACKING.

Changes

• Graph labels are now overlayed on top of the graph instead of placed beside them.

• MPRIS2 Widgets will remain visible when their players are in the paused state.

• getSongInfo now doesn’t automatically return Nothing when xesam:artist is missing. This makes the MPRIS2 Widget display in more situations than before.

• Network graph will have a tooltip by default.

• The SNI Tray will respect ItemIsMenu property to handle mouse left click.

Bug Fixes

• Center widgets will now properly expand vertically.

• Errors, including icon missing from theme errors, in workspace pixbuf getters are now handled gracefully.

• A workaround to properly display the chrome icon in MPRIS was added.

3.3.0

Bug Fixes

• Compatibility with newer versions of GHC.

New Features

• A wttr.in widget was added.

• Make memoryAvailable action available inside the Text MemoryMonitor widget.

• The SNI Tray supports triggering Activate and SecondaryActivate on icons.

• Better formatting for Text MemoryMonitor Widget

3.2.2

Bug Fixes

• Solve space leaks on updateSamples and getDeviceUpDown (#472).

• Prevent crash when using mpris2New and librsvg is not available (#478).

• Fixed compilation issues that appear when using ghc 8.8.

3.2.1

Bug Fixes

• The workspaces widget now listens on the additional EWMH properties that it needs to in order to properly update things when the active window changes. This problem likely only emerged recently because xmonad has recently become much more conservative about emitting change events (#454).

• The workspaces widget listens for changes to window geometry (similar to above) (#456).

3.2.0

New Features

• The Layout widget can now be styled with the css class “layout-label”.

• A new polling label function pollingLabelWithVariableDelay that allows for variable poll times was added.

• A new widget System.Taffybar.Widget.SimpleCommandButton was added.

• Taffybar now outputs colorized and annotated logs by default.

Breaking Changes

• The file specified in the cssPath parameter in config is now used instead of, rather than in addition to the default user config file.

• All parameters are now passed to textClockNewWith as part of the ClockConfig it receives. A new mechanism for rounded variable polling should allow the clock to always remain accurate (to the precision selected by the user) without having a very high polling rate, thus reducing CPU usage.

• The polling label functions no longer accept a default text parameter.

Miscellaneous

• Battery updates are only triggered when a more limited number of UPower properties are changed. This can be customized by manually calling setupDisplayBatteryChanVar as a hook.

Bug Fixes

• Calendar pops up below bar without hiding any other widget #261.

• Avoid failing when parsing XDG Desktop files with unrecognized application type, which previously resulted in “Prelude.read: no parse” #447.

• Use XDG data dir so that taffybar dbus toggling functions correctly when taffybar is installed in a location that is not writable by the user. This is the case with nix when it is installed in the nix store #452.

3.1.2

Updates

• Weather now uses new uris and https (Kirill Zaborsky)

• Bump the version of gi-gdkpixbuf, this fixes nixpkgs compilation

3.1.0

New Features

• A new module Chrome which makes it so that Workspaces can display the favicons of the website that the chrome window is currently visiting.

3.0.0

Breaking Changes

• Taffybar has replaced gtk2hs with gi-gtk everywhere. All widgets must now be created with gi-gtk.

2.0.0

Breaking Changes

• An entirely new config system has been put in place. TaffybarConfig now lives in System.Taffybar.Context, but for most users, System.Taffybar.SimpleConfig is the configuration interface that should be used.

• The main entry point to taffybar is now dyreTaffybar instead of defaultTaffybar.

• All widget constructors provided to both config systems must now be of type TaffyIO Gtk.Widget. If you have an existing IO Gtk.Widget you can convert it using liftIO. All widgets provided by taffybar are now of type MonadIO m => m Gtk.Widget, or specialized to TaffyIO Gtk.Widgets.

• The graphBackgroundColor and graphBorderColor fields are now RGBA quadruples instead of RGB triples.

• Module removals:

  • WorkspaceSwitcher: Workspaces is much more abstract and makes this widget redundant.
  • Pager: The Context module solves the problem that Pager solved in a much more general way. It also makes it so that the user doesn’t even need to know about the Pager component at all.
  • TaffyPager: Since you no longer need to explicitly initialize a Pager, it’s not really very hard to simply add the (Workspaces, Layout, Windows) triple to your config any more.
  • XMonadLog: This module has long been deprecated

• Module moves:

  • Everything in System.Information has been moved to System.Information.Taffybar
  • All Widgets that were found in System.Taffybar have been moved to System.Taffybar.Widget
  • The helper widgets that were previously located in System.Taffybar.Widgets have been moved to System.Taffybar.Widget.Generic

• Module renames:

  • WorkspaceHUD -> Workspaces
  • WindowSwitcher -> Windows
  • LayoutSwitcher -> Layout
  • ToggleMonitors -> DBus.Toggle

• Module deprecations:

  • System.Taffybar.Widget.Systray (Use SNITray instead)
  • System.Taffybar.Widget.NetMonitor (Use System.Taffybar.Widget.Text.NetworkMonitor instead)

• Many widgets have subtle interface changes that may break existing configurations.

New Features

• Widgets can now be placed in the center of taffybar with the centerWidgets configuration parameter.

• taffybar is now transparent by default, but you will need to use a compositor for transparency to work. https://github.com/chjj/compton is recommended. If you do not want a transparent taffybar set a background color on the class TaffyBox in taffybar.css.

• StatusNotifierItem support has been added to taffybar in the SNITray module.

• Monitor configuration changes are handled automatically. Unfortunately the bar must be completely recreated when this happens.

• New network monitor widgets System.Taffybar.Widget.Text.NetworkMonitor and System.Taffybar.Widget.NetworkGraph were added.

• All widgets are now exported in System.Taffybar.Widget, which should eliminate the need to import widgets explicitly.

1.0.2

Bug Fixes

• Fix long standing memory leak that was caused by a failure to free memory allocated for gtk pixbufs.
• Widgets unregister from X11 event listening.

• Compile with gtk2hs 0.13

Bug Fixes

• Reduce wakeups by tweaking the default GHC RTS options (Joachim Breitner)
• UTF8 fixes (Nathan Maxson)
• Various fixes to EWMH support (José Alfredo Romero L)

Deprecations

The XMonadLog module is deprecated. This module let taffybar display XMonad desktop information through a dbus connection. The EWMH desktop support by José Alfredo Romero L is better in every way, so that (through TaffyPager) is the recommended replacement. Upgrading should be straightforward.

0.3.0:

• A new pager (System.Taffybar.TaffyPager) from José A. Romero L. This pager is a drop-in replacement for the dbus-based XMonadLog widget. It communicates via X atoms and EWMH like a real pager. It even supports changing workspaces by clicking on them. I recommend this over the old widget.
• Added an MPRIS2 widget (contributed by Igor Babuschkin)
• Ported to use the newer merged dbus library instead of dbus-client/dbus-core (contributed by CJ van den Berg)
• Finally have the calendar widget pop up over the date/time widget (contributed by José A. Romero)
• GHC 7.6 compatibility
• Vertical bars can now have dynamic background colors (suggested by Elliot Wolk)
• Bug fixes

0.2.1:

• More robust strut handling for multiple monitors of different sizes (contributed by Morgan Gibson)
• New widgets from José A. Romero (network monitor, fs monitor, another CPU monitor)
• Allow the bar widget to grow vertically (also contributed by José A. Romero)

0.2.0:

• Add some more flexible formatting options for the XMonadLog widget (contributed by cnervi).
• Make the PollingLabel more robust with an exception handler for IOExceptions
• Added more documentation for a few widgets

0.1.3:

• Depend on gtk 0.12.1+ to be able to build under ghc 7.2
• Fix the background colors in the calendar so that it follows the GTK theme instead of the bar-specific color settings
• Fix the display of non-ASCII window titles in the XMonad log applet (assuming you use the dbusLog function)
• Add a horrible hack to force the bar to not resize to be larger than the screen due to notifications or long window titles

0.1.2:

• Readable widget for freedesktop notifications
• Fixed a few potential deadlocks on startup
• Use the GTK+ rc-file styling system for colors instead of hard coding them
