dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

I made a similar volume bar with pygtk earlier. This is the same concept but more attractive for tiling window managers. For this you will need the following dependencies: dzen2, alsa-utils, sed, coreutils, bash.

The basic idea is that you bind multimedia keys to this program and then when you press them, a volume bar pops up briefly showing the change.

Here is a close up screen.

Here is what it looks like on the entire screen:
http://i28.tinypic.com/swzs4k.png

Here is the script, notice that the look and placement and other things are customized by editing the variables at the top of the script. IF is the amixer interface (most likely Master) and SECS is the seconds you want the volume bar to linger after displaying. The rest is obvious. Just copy and paste this into a text file in the PATH called "dvol" and chmod +x it.

#!/bin/bash

#Customize this stuff
IF="Master"
SECS="1"

FONT="fixed"
BG="grey"
FG="black"
XPOS="550"
YPOS="400"
WIDTH="205"

#Probably do not customize
PIPE="/tmp/dvolpipe"

err() {
  echo "$1"
  exit 1
}

usage() {
  echo "usage: dvol [option] [argument]"
  echo
  echo "Options:"
  echo "     -i, --increase - increase volume by \`argument'"
  echo "     -d, --decrease - decrease volume by \`argument'"
  echo "     -t, --toggle   - toggle mute on and off"
  echo "     -h, --help     - display this"
  exit
}

#Argument Parsing
case "$1" in
  '-i'|'--increase')
    [ -z "$2" ] && err "No argument specified for increase."
    AMIXARG="${2}%+"
    ;;
  '-d'|'--decrease')
    [ -z "$2" ] && err "No argument specified for decrease."
    AMIXARG="${2}%-"
    ;;
  '-t'|'--toggle')
    AMIXARG="toggle"
    ;;
  ''|'-h'|'--help')
    usage
    ;;
  *)
    err "Unrecognized option \`$1', see dvol --help"
    ;;
esac

#Actual volume changing (readability low)
AMIXOUT="$(amixer set "$IF" "$AMIXARG" | tail -n 1)"
MUTE="$(cut -d '[' -f 4 <<<"$AMIXOUT")"
if [ "$MUTE" = "off]" ]; then
  VOL="0"
else
  VOL="$(cut -d '[' -f 2 <<<"$AMIXOUT" | sed 's/%.*//g')"
fi

#Using named pipe to determine whether previous call still exists
#Also prevents multiple volume bar instances
if [ ! -e "$PIPE" ]; then
  mkfifo "$PIPE"
  (dzen2 -l 1 -x "$XPOS" -y "$YPOS" -w "$WIDTH" -fn "$FONT" -bg "$BG" -fg "$FG" -e 'onstart=uncollapse' < "$PIPE" 
   rm -f "$PIPE") &
fi

#Feed the pipe!
(echo "Volume" ; echo "$VOL" | dbar ; sleep "$SECS") > "$PIPE"

The usage information can be found with dvol --help. But here it is:

usage: dvol [option] [argument]

Options:
     -i, --increase - increase volume by `argument'
     -d, --decrease - decrease volume by `argument'
     -t, --toggle   - toggle mute on and off
     -h, --help     - display this

Edit: Added FONT variable.

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

Thanks for this, bruenig. I was a big fan of your changevol script as well.

Edit:

As an FYI, it might be nice to include the FONT variable as well.  I've added it to mine so I can use terminus instead of terminal (or whatever the default font is).

Thanks again!

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

Hey these are great! I've been using the changevol script for a while now... Have you considered putting these in AUR? I know I'd appreciate not having to find the thread or copy from a previous installation if I'm building a new system...

For those of you who like a more graphical output I modified the script slightly:

}

usage() {

  echo
  echo "Options:"
  echo "     -i, --increase - increase volume by \`argument'"
  echo "     -d, --decrease - decrease volume by \`argument'"
  echo "     -t, --toggle   - toggle mute on and off"
  echo "     -h, --help     - display this"
  exit
}

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

Ashren,  looks like you could strip all the FONT stuff out of yours, you don't output any text at all.  Looks good though.

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

ashren: beatiful!
For ashren's version you also need dzen2-gadgets (which contains gdbar)
On my system there is no spkr_01.xbm btw. (I only have some gtk themes and tango installed, that's it)

edit: whoa.. gdbar is the shit : http://dzen.geekmode.org/dwiki/doku.php … bar-styles

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

Great stuff! I've modified this a bit further:

* volume bar can now have separate foreground and background colours from the title window and icon
* width of bar is now adjustable to compensate for different icons/fonts (originally pushing it to 100% sent the bar outside the title window)
* height variable offers vertical padding

Here's a gaudy screenshot to show the differences:

FYI: gdbar is included in the standard dzen2 package.

Oops, you're right.  I was getting 'gdbar: command not found' errors when I first tried this script (and i had dzen2 installed)

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

hi! i love this script! but im looking forward to make it a full size top bar like the screenshot but i cant seem to get the second line right...

53394746.png

i certainly love to have this in a one line bar like this

VOLUME: 80% [=============    ]

so i can edit this script to show other things like battery, disk space, etc

Thanks to the bumping I've just found this thread, thanks for this script! I have it bound in Xmonad to ctrl-alt j/k for dvol -d 1 and dvol -i 1 respectively, and h/l for mpc prev and mpc next (Yes, weird I know, but I'm used to it now tongue)

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

I have edited it to be a top bar instead

EDIT: for some reason, you need to wait for the number of secs specified in $SECS, and the bar doesn't have a fixed size, it resizes with every volume change)

same with only the percentage value, for some reason, you need to wait for the number of secs specified in $SECS, i think because of the "-e onstart=uncollapse" variable in dzen2

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

Love these scripts, thanks for sharing!

One issue though: when I toggle the mute function, I was kind of expecting the volume bar to go empty. I've spent a while trying to get this functionality to present itself, but I'm afraid I just don't understand the volume-changing part very well at all. I'm also considering changing the icon to an empty speaker, and maybe having the color be red. The script I'm using is thayer's with only size and color modifications. If anyone who uses this has had any luck, please help me out!

Thanks

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

I modified Ashren's version and used Thayer's icons. The modification centers the whole thing, adds a mute icon and interface indication. The interface may be given in an extra argument. To center everything, it uses xdpyinfo and awk.

#Customize this stuff
IF="Master"
SECS="2"

BG="#43464f"
FG="#9ab8c2"
WIDTH="250"
WIDTH_BAR=$(($WIDTH - 150))
WINDOW_WIDTH=$(xdpyinfo | awk '$1 ~ /dimensions/ {split($2,arr,"x"); print int(arr[1])}')
WINDOW_HEIGHT=$(xdpyinfo | awk '$1 ~ /dimensions/ {split($2,arr,"x"); print int(arr[2])}')
XPOS=$((($WINDOW_WIDTH / 2) - ($WIDTH / 2)))
YPOS=$(($WINDOW_HEIGHT / 2))

ICON_VOL=~/.dzen2/thayer/vol-hi.xbm
ICON_VOL_MUTE=~/.dzen2/thayer/vol-mute.xbm
ICON=$ICON_VOL

#Probably do not customize
PIPE="/tmp/dvolpipe"

  echo "     -h, --help     - display this"

(echo "$VOL" | gdbar -l "$IF ^i(${ICON}) " -fg "$FG" -bg "$BG" -w $WIDTH_BAR ; sleep "$SECS") > "$PIPE"

Note: make sure you set the correct path for the volume and mute icons.

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

@palaga

Using two awks can really slow that thing down. At least switch to an array

WINDOW=( $(xdpyinfo | awk -F ' |x' '/dimensions/ {print $7 " " $8}') )

WINDOW[0] will be widht and WINDOW[1] will be height.

Or, to speed it up even more grep -F and some cuts would actually probably be faster than awking while using regex (which is way heavier than some realize).

Re: dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

I'm using thayers version but I got a small problem. When the sound level is between 61 and 99 it renders incorrectly, like shown in the image. I haven't configured it at all an I got the dina font installed so I've got no idea what the problem is. Is there anyone who can reproduce this, or give me a solution?

I could be wrong, but I seem to recall it was an issue with Dina.  Looking at my current config (which works) I switched back to Terminus.
