# xmonad-pulsevolume |
||||
Scripts for setting and visualizing pulseaudio volume with XMonad+xmobar (and maybe others). |
||||
|
||||
## Purpose |
||||
|
||||
* Easily change pulseaudio volume from xmonad |
||||
* Visualize volume in xmobar. Here are some snapshots of the representation in increasing volume: |
||||
|
||||
``` |
||||
[ (mute) ] |
||||
[ ] |
||||
[. ] |
||||
[- ] |
||||
[/ ] |
||||
[/. ] |
||||
[/- ] |
||||
[// ] |
||||
[//. ] |
||||
[///- ] |
||||
[////. ] |
||||
[//////////] |
||||
``` |
||||
|
||||
## Install & Use |
||||
|
||||
0. Dependencies: working xmonad, pulseaudio. For visualization: python, xmobar. |
||||
1. Add pulse-volume.sh and show-volume.py somewhere on your $PATH. |
||||
2. Update xmonad.hs for media buttons. I add the following keybindings: |
||||
``` |
||||
-- mute button |
||||
, ((0 , 0x1008FF12), spawn "pulse-volume.sh toggle") |
||||
|
||||
-- volumeup button |
||||
, ((0 , 0x1008FF13), spawn "pulse-volume.sh increase") |
||||
|
||||
-- volumedown button |
||||
, ((0 , 0x1008FF11), spawn "pulse-volume.sh decrease") |
||||
``` |
||||
3. Update xmobar configuation to run python script. The important thing is to add to the 'commands' array, and to the template. Here's a full example: |
||||
``` |
||||
Config { font = "xft:Droid Sans Mono:size=9:antialias=true" |
||||
, bgColor = "#181818" |
||||
, fgColor = "green" |
||||
, position = TopW L 95 |
||||
, commands = [ Run Cpu ["-L","3","-H","50","--normal","green","--high","red"] 5 |
||||
, Run Memory ["-t","Mem: <usedratio>%"] 5 |
||||
, Run Date "%a %b %d %Y %H:%M:%S " "date" 1 |
||||
, Run Com "python" ["/path/to/show-volume.py"] "vol" 1 |
||||
, Run StdinReader |
||||
] |
||||
, sepChar = "%" |
||||
, alignSep = "}{" |
||||
, template = "%StdinReader% }{ %cpu% | %memory% %vol% <fc=#e0e0e0>%date%</fc>" |
||||
} |
||||
``` |
||||
|
||||
4. (Optional) Upon boot, I like to reset the volume to what I consider a reasonable volume and unmute. In my .xsession file I run `pulse-volume.sh reset`. This also ensures that ~/.mute and ~/.volume are correct (see below). |
||||
5. Restart xmonad. |
||||
|
||||
## Under the hood and future work |
||||
|
||||
The pulse-volume.sh script maintains two files in your home directory: ~/.volume and ~/.mute. Whenever you run this script it reads the current volume from the file and updates it appropriately (it takes a parameter "increase", "decrease", "mute", "unmute", "toggle"). It also updates pulse-volume. If this file is changed between uses of the script, the volume can jump dramatically; hence the "reset" feature to go back to a fixed volume. Obviously, it would be better to get the current volume from pulse audio itself instead of replicating state... contributions welcome! |
||||
|
||||
./show-volume.py generates the graphical representation from these files. It takes no parameters -- run it from the command line to see what it does. It's very easy to hack on this to make a new visualization... let me know if you do something cool! |
||||
|
||||
I expect you can use these scripts with other window managers or status bars, like dzen2. I somehow doubt there's much need -- but if you find it useful, feel free to contribute additions. |
||||
|
||||
## Bugs |
||||
|
||||
I wrote this years ago and never really intended to release it. Yet, it's stood the test of time for me, and I automatically deploy it on several linux systems without issues. However, given that nobody **else** has ever tested it, I imagine it has a lingering issue or two -- even if only in the setup instructions that I wrote. |
||||
