taffybar / taffybar

A gtk based status bar for tiling window managers such as XMonad

Taffybar

Taffybar is a gtk+3 (through gi-gtk) based desktop information bar, intended primarily for use with XMonad, though it can also function alongside other EWMH compliant window managers. It is similar in spirit to xmobar, but it differs in that it gives up some simplicity for a reasonable helping of eye candy.

Before Installing

Taffybar's installation procedure varies depending on whether or not you intend to setup a new haskell project and use startTaffybar or use the dyreTaffybar with a global haskell installation . It is important for you to read this section so you can understand what all of that means before you decide how you want to install taffybar.

Taffybar is a library

As with window managers like XMonad and dwm, taffybar is most appropriately described as a library that allows you to build an executable that is customized to your tastes. This means that taffybar must be installed alongside a haskell compiler (ghc) that can compile the user's configuration source file.

The taffybar binary and startTaffybar vs dyreTaffybar

Taffybar can be started from your configuration file in two different ways:

dyreTaffybar

The dyreTaffybar entry point to taffybar uses the dyre library to automatically recompile your taffybar configuration whenever it detects that it has changed. The binary that is distributed with taffybar does nothing more than call this entry point. The main downside of this approach is that it does not allow the user to use any sort of project files for their configuration, and they must have any packages that are necessary for compilation of their configuration available in their global ghc environment.

startTaffybar

The startTaffybar entry point to taffybar simply starts taffybar with the provided configuration. The user binary will not be automatically recompiled when source files change. The advantage of using startTaffybar directly is that you can use that in the main function of a cabal project.

Distribution Packaging

Several linux distributions package taffybar (nixos, arch/aur, debian). Of these, only the NixOS distribution is officially supported by the maintainers. Using any of the others should be pretty similar to using a bare cabal installation of taffybar.

NixOS

If you wish to use the NixOS package for taffybar, make sure that you are using the module, and not simply the haskellPackage for taffybar. If you need to add additional haskell packages to the environment that compiles your taffybar.hs you will need to invoke that module and use the packages parameter to allow this.

It is also possible to run/use taffybar on NixOS without using this module by using a standalone haskell project for the taffybar configuration.

Using the overlay.nix when taffybar is broken in nixpkgs

The taffybar haskell package in nixpkgs has been broken in the unstable channel from time to time. This repository provides a nix overlay file which can be used to build taffybar with current versions of nixpkgs. See this comment for details on how to use the overlay.

Installation From Hackage/Source

Prerequisites

If you are not using distribution packaging of taffybar or the nix package manager (it will handle getting all the necessary packages for you), you will need to install all of taffybar's non-haskell dependencies manually.

Start by making sure you have installed everything that is needed for haskell-gi. Taffybar also needs the equivalent of libdbusmenu-gtk3-dev and libgirepository1.0-dev on Debian.

You can also get some idea of what the necessary dependencies are by looking at the nix section of the stack.yaml file in the taffybar repository.

Cabal

Cabal installation is a simple matter of installing taffybar from hackage:

cabal install taffybar

You do not need to do this if you are using the project approach with cabal.

The project approach

The project approach to installing/using taffybar involves maintaining a small haskell project that produces the users taffybar binary. No matter which package manager you choose to use you will need to make a .cabal file for this project. It is recommended that you use this example as a template. In that example, the users configuration resides in the file taffybar.hs in the same directory, but that can be changed as needed. As of right now, dyreTaffybar is incompatible with this approach because dyre simply calls ghc directly.

Cabal

Simply run cabal new-install to install the binary.

Stack

With stack, you will also need to maintain a stack.yaml file. Run stack install to install the binary. See this example

Nix

You will need to add default.nix file to your package. See this example

You may also need to use the overlay provided by this repository. See this comment for details.

Overlay

The taffybar haskell package is currently broken in nixpkgs, because some of its dependencies are not compiling correctly/are not sufficiently new. The environment.nix file in this repository fixes these build issues with an overlay. The overlay.nix file extends the environment overlay so that it overrides the taffybar package's build description to build the nix taffybar package from the repository source directory. An example of how to set up nixpkgs to use the taffybar overlay can be found here.

Configuration

Like xmobar and XMonad, taffybar is configured in haskell. Taffybar depends on dyre to automatically detect changes to its configuration file ($XDG_CONFIG_HOME/taffybar/taffybar.hs) and recompile when appropriate.

For more details about how to configure taffybar, see the full documentation. You can find a list of available widgets here.

New pager doesn't work with dynamic workspaces

I'm using XMonad's dynamic workspaces module, and this worked fine with the dbus log, but I've switched over to TaffyPager. It seems that workspaces are only read when Taffybar is started, could you possibly provide a callback to re-read the workspaces?

Too many wakeups in clock and cpu widget

powertop lists taffybar as the worst offender. Commenting out the widgets one by one I found that of those that I use, most behave well (e.g. block until something happens). But the cpu and clock widgets cause many updates per seconds (~70/s resp. ~44/s), despite being told to update once per second.

I didn’t debug this yet.

For the clock widget: Wouldn’t it make more sense to sleep until the time changes the next time? A bit annoying to implement that logic, but it would prevent a few unnecessary wakeups.

Calendar doesn't respect color scheme nor gtk-engine

First of all, thanks you for taffybar... it's just what i was looking for and it's great :D

The calendar doesn't seem to respect colors of the gtk theme nor the engine rendering, the calendar just looks like the default engine/colors. I tried to workaround this using the taffybar.rc with no results.

As a request, some option to add margins (right and left) cause i think the first and last characters are too close to the edge of the screen.Maybe adding something like pangoColor for the pp :D.

And for documentation purposes add a xmonad.hs example and add how to change the taffybar font maybe good idea.

Add network-uri depends

Taffybar does not currently build:

Preprocessing library taffybar-0.4.1...

src/System/Taffybar/Weather.hs:75:8:
    Could not find module ‘Network.URI’
    It is a member of the hidden package ‘network-uri-2.6.0.1’.
    Perhaps you need to add ‘network-uri’ to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.

The network package has recently been split into network and network-uri packages so this is really just a matter of adding network-uri as a dependency.

current month calendar days invisible in taffybar > 0.1.0

First thanks for taffybar! It is pretty cool already. :)

I haven't investigated the cause yet but after upgrading to 0.1.1 and 0.1.2
I noticed that the days in the current calendar month are no longer visible.
I suspect they may be being rendering in white on white somehow?
I can see today highlighted and the surrounding days from the previous
and next month but not the rest of the days for the current month.

I guess also ideally the calendar would appear under the time-date widget
but that is probably longer term polishing.

Installation document

I tried to install cabal install:

cabal install taffybar
Resolving dependencies...  
cabal: dependencies conflict: xmonad-contrib-0.10 requires mtl ==1.1.0.2
however
mtl-1.1.0.2 was excluded because taffybar-0.1.3 requires mtl >=2

A document to show how I install it from source would be nice.

`/proc/meminfo` format change in Linux 3.14 breaks `parseMeminfo`

Since Linux 3.14, there is an additional MemAvailable entry in /proc/meminfo that occupies the 3rd line, causing parseMeminfo to fetch the wrong values for buffer and cache. I think we should switch to more robust methods for parsing /proc/meminfo instead of relying on line numbers.

Should work even when started before dbus

Hi,

when starting taffybar from a script sourced by xinit, it may be the case that it is started before dbus is available, and I get

Jul 19 17:14:42 kirk /etc/gdm3/Xsession[19419]: taffybar-linux-x86_64: ClientError {clientErrorMessage = "connectSession: DBUS_SESSION_BUS_ADDRESS is missing or invalid.", clientErrorFatal = True}

in the logs. It should handle this gracefully and just begin to use dbus when it is available.

Battery widget can hang on startup

This is related to #44. Most of the battery widget code runs in its own thread, but some initialization code (that apparently can hang indefinitely) runs in the main thread at taffybar startup time. This code (batteryContextNew) should be moved to a separate thread or have a timeout.

automated vertical orientation

Taffybar should support placing itself vertically - user should specify it only once in the config and all the widgets should "inherit" or autodetect that property and behave accordingly: text should be rendered vertically and not sideways, pager and alike should grow vertically instead of horizontally and so on.

That's especially handy with the proliferation of wide-screen monitors where vertical screen estate is much "cheaper" than horizontal.

System.Taffybar.Weather doesn't allow to redefine weather format

I almost don't know Haskell (so sorry if this ticket is incorrect). I tried to change the Weather widget format, but it seems like corresponding module doesn't export DefaultWeatherFormatter. At least I didn't find the way to redefine the format. Could you provide the example?

Taffybar not installing via cabal

I did not find any mailing list for taffybar, so I'm posting this here.
After recent update to ghc 7.6.1 taffybar stopped building via cabal: looks like it depends on an outdated library. Here's a build log:

Add MPRIS2 support

The MPRIS widget currently only supports MPRIS1

LayoutSwitcher does not work with chinese characters

LayoutSwitcher does not display layout names with chinese characters in them. It seems that this is a problem in pagerHints, as manually viewing the xpropertys for the root window with xprop -root shows

_XMONAD_CURRENT_LAYOUT(UTF8_STRING) = "

It should be noted that my workspace names are in chinese characters, and that they seems to work fine

Trick Hackage into building documentation

This is continued from the comments in Issue 12. For some reason, Hackage refuses to generate the taffybar documentation.
The log reports a build failure due to missing dependencies (related to gtk2hs). These dependencies exist. Some gtk2hs packages on hackage have documentation built, while others do not. I haven't seen any patterns between them.

Lines on graphs

Hi,

I would appreciate the possibility to add line graphs to the graph widget. Especially when displaying multiple values in one graph, this would be handy.

In my case, I’d like to have a filled-below-the-line-graph (as we have it now) for the CPU temperature, and superimposed a line graph showing the fan speed.

Thanks,
Joachim

Make it easy to specify that you would like to monitor all network interfaces

With http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
interfaces can be called enpXsY instead of ethX. This breaks the last bit of "portability" like "luckily all my machines have eth0 and that's all I use so using the exact same taffybar.hs works and is trivial to keep in sync".

I suggest to a convenient to address "all interfaces" (with option to exclude some like "lo" or other edge cases).

Use case: "For each of my interfaces, show me according to this ."

Example configs?

Taffybar is running smooth, low cpu, easy install via cabal. Wondering if you could include some more examples in the sample taffybar.hs file. I'm hitting a wall trying to get the battery indicator running. Alternately, or in addition, a list of other taffybar.hs samples elsewhere on github/etc. would be useful as examples. I didn't find any on a quick search but I'm sure they are out there.

Multimonitor support

I'm the developer/maintainer of X.H.DynamicBars in xmonad-contrib. It'd be nice if taffybar integrated with it. I see a few ways it could be done

• DBus method call for monitor add/remove events (if keeping a single taffybar instance which draws multiple bars)
• Take a monitor number on the command line (multiple instances; one per screen)

Maybe there's a better way?

multimonitor support in pager

TaffyPager should correctly detect addition/removal of monitors and visually highlight which workspaces currently visible through monitors and which one is active at the moment.

Escape '&' in XMonadLog

When, e.g. a window title contains an '&', and XMonad is set up to log to taffybar, the title is not updated and the following error is seen on taffybar's output:

Gtk-WARNING **: Failed to set text from markup due to error parsing markup: Error on line 1: Entity did not end with a semicolon; most likely you used an ampersand character without intending to start an entity - escape ampersand as &

Sort workspaces in Workspaces Widget

I would like to sort workspaces by tag but the PagerConfig doesn't have any options to change the order. Is it possible to do it in TaffyBar? I tried to use dynamicLogWithPP myPP in my logHook in xmonad.hs but it doesn't affect TaffyBar and I'm not sure why.

Current keyboard layout

Hello!
Do you have some ideas to implement widget showing current keyboard layout?
You can use https://github.com/aartamonau/haskell-x11-xkb or https://github.com/jaor/xmobar/blob/master/src/Plugins/Kbd.hsc
If I have time, I will try to implement myself.

Battery widget can hang on resume from sleep

I've noticed sometimes my battery widget hangs when I resume from sleep keeping the exact same text (I assume) it had prior to going to sleep. Usually I put it to sleep with the cord plugged in and sometimes I start it up without it plugged in, but I'm not sure if it makes a difference. I can't seem to reproduce it reliably though, but it seems to happen more often if it's been asleep for a little while.
I've poked around in the code a bit and been unable to determine what's going wrong, but I'll gladly look some more if anyone has any ideas.

Next release?

Any chance we might see a new release on hackage soon? The ability to build against gtk 0.13 is really nice to have, and releases on hackage play much nicer with the haskell infrastructure in nixos.

Add option to make graph add new values to the right side

Currently I feel that the graphs are moving in the wrong direction :) An option to make them move in the other direction would be very nice.

This is probably very simple to do and I might have a go at it in the near future. However my Haskell skills are almost non-existent so I'll have to some learning first...

Date widget does not pick up on DST changes without restart

This is a really minor and weird bug. It seems that the time in the date widget does not pick up on DST (daylight savings time) changes till restarted. So for example just recently DST was turned off on the 3rd of November, but the time kept on showing as if DST was still active till I restarted it.

Taffybar hangs on FUTEX_WAIT_PRIVATE

Often Taffybar hangs, appearing not to launch. Recently I made the switch to TaffyPager, and afterwards I began to experience this behaviour. The full strace is below

strace taffybar

http://puu.sh/3NOOW.txt

Don't just fail/hang when no config file can be found

It's extremely confusing that the if the config file is missing or misspelled. The bar just starts blank. Leaving users clueless if there graphics driver is flawed or if taffybar really should start blank.

Instead it could display something like "Welcome to taffybar, configure at $HOME/.config/taffybar/taffybar.hs"

dbusLog conflicts(?) with ewmh

When I turn on dbusLog hook EWMH hooks (from XMonad.Hooks.EwmhDesktops) stop working (e.g. I don't get correct window with xprop -root _NET_ACTIVE_WINDOW) and othe programs need EWMH.
Looking through the code I don't see why this could happen.
Any hints?

Could not get taffybar into statusbar area

I'm playing around in VirtualBox to get proper xmonad setup. I want to use taffybar but could not get it's window into proper area. It just starts as normal window - http://imgur.com/a3adi
My current xmonad config is quite basic - http://paste.debian.net/151240/
I use Ubuntu Oneiric, xmonad 0.10 and taffybar 0.1.3 (both installed with cabal)
What am I doing wrong and is there some proper way to install taffybar?

unable to start taffybar

Hi everyone,
I installed taffybar from haskell-core in archlinux and used the default template for taffybar.hs from the repository (https://github.com/travitch/taffybar/blob/master/src/System/Taffybar.hs)
I keep getting the following error:
Configuration '/home/abhinav/.config/taffybar/taffybar.hs' changed. Recompiling.
Error occurred while loading configuration file.
Error:

taffybar-0.1.3 doesn't really need gtk >= 0.12.1

Hi, I see you bumped the gtk dependency for ghc-7.2 (and same for gtk-traymanager),
and I am just wondering if this really helps anyone? :)

Yes, I understand that ghc-7.2 needs gtk-0.12.1 but
the latest taffybar code builds fine with gtk-0.12 on ghc-7.0, and
there is not really any advantage for ghc-7.0 users to upgrade
to gtk-0.12.1. So from my point of view (tell me if I am wrong:)
bumping the gtk depends is just making life harder for 7.0 users,
which is still the default for haskell-platform. So my suggestion
is to relax the dependency on gtk to 0.12.* again.

Thanks for taffybar. :)

TaffyPager does not honor widgetSpacing

TaffyPager ignores widgetSpacing. Specifically when I set the widgetSpacing to 0, the spacing between the workspace names is not 0

Urgent workspaces broken in the new EWMH pager

The new pager I recently merged in does not seem to highlight urgent desktops anymore. I haven't looked in to the cause of the problem yet. @teleshoes @escherdragon do either of you use that feature?

Latest version on Hackage is 0.2.1

Would it be possible to upload the 0.2.2 release to Hackage? Alternatively, produce a new release and put that on Hackage?

Reflect Layout Geometry in Workspaces Image Area

Instead of icon in pager I would rather see preview of the layout for each workspace (with icons for windows which are big enough) which is properly filled according to number of windows currently present in particular layout.

For example if I have regular "split non-master region in half" layout it should show 50%/50% split for 2 windows and 50%/25%/25% split for 3 windows and icon should be displayed only on 50% parts if 25% is too small.

All the necessary information is available inside of xmonad but it's impossible to communicate it to regular pager. Utilizing this information would really set taffybar apart from hundreds of other pager available out there.

memory read incorrectly with newer /proc/meminfo

on kernel 3.14 debian sid.
new line in /proc/meminfo, MemAvailable, breaks System.Information.Memory

Respond to `--version` and `--help`

Currently it happily ignores all command line arguments.

System.Taffybar.Weather assumes everyone lives in the US

The Weather element suggests that people can specify the weather at their location from one specified at http://www.nws.noaa.gov/tg/siteloc.php (which redirects to something else).

Unfortunately, that does not work if people outside the US.

It would be nice if this could be made more general, maybe using something like libgweather.

additional build dependency?

This may be a general cabal failing, or perhaps a missing dependency from a non-taffybar package. gtk2hs-buildtools is a build-dependency (for glib) and is the only package that I have to tell cabal to install manually prior to cabal install taffybar. I'm not sure if it can or should be added to taffybar's build dependency list, but thought I'd mention it.

Small error in documentation of `pollingLabelNew`.

In the documentation of pollingLabelNew, it refers to updatingLabelNew.

Merge CPU Info modules

I've been thinking about making a release soon, but I'd like to consolidate the two CPU Info modules before I do so that I don't feel quite so obligated to support two for an indefinite period.

I should have asked when I merged it, but @escherdragon could you fill me in on what is different about the version you introduced in #19?

I want to merge it into the existing one if possible, just including all of the features from both.

Building with gtk 0.13.1

I needed to add the following patch in order to build with the latest gtk:

XBM/XPM Icon support

Would it be possible to implement icon support with Graphics.X11.Xlib?
This landed in Xmobar quite some time ago, and their process seems to be relatively well documented here: https://github.com/jaor/xmobar/pull/87

Station locator URL is invalid

http://lwf.ncdc.noaa.gov/oa/climate/stationlocator.html from haddocks seems to be invalid. I tried but could not find new URL for it.
Actually I wanted to get some more info on this weather service because http://weather.noaa.gov/pub/data/observations/metar/decoded/ULAA.TXT seems to be stuck on data from 1st August and did not get anything useful from NOAA website.

Clock doesn’t follow timezone changes

Hi,

I just changed my timezone, but taffybar’s clock is not picking up the change.

Greetings,
