Hehe, very cool! So, I finnaly found the author big_smile.
I stumbled upon your code while searching google and was amazed to see a dzen driver in Scheme smile.

Btw, I don't find Scheme to be more exotic than Haskell smile

No, it's surely not more exotic, though Haskell is also not a what i would call "mainstream" language wink.

An slightly updated version is here:

So, if you find some spare time please update the wiki entry preferably with a short description and a screenshot of your code in action.

I actually updated the code already, with attribution going to tizoc... but a screenshot would be great.

Re: dzen & xmobar Hacking Thread

Trying this out for the first time, albeit with fluxbox rather than xmonad or whatever. For some reason it tells me it can't load terminus, even though I do indeed have terminus-font installed.

dzen: error, cannot load font: '-*-terminus-*-r-normal-*-*-120-*-*-*-*-iso8859-*'

Also, I've noticed that conky is still drawing to the desktop, and this is rather annoying. I notice it doesn't show up on anyone else's screenshots, is this because I'm using fluxbox? Either way, how do I get rid of it?

Configs for reference:

#conkyrc for dzen

background        no
out_to_console        yes

For terminus to work, you have to add the font path to your xorg.conf:

Section "Files"
    ...
    FontPath     "/usr/share/fonts/local"        # added for Terminus
    ...
EndSection

As for conky printing to screen, are you sure you are running conky-cli (it's in the AUR)?

Re: dzen & xmobar Hacking Thread

HEADS UP. in latest SVN dzen (svn checkout http://dzen.googlecode.com/svn/trunk/ dzen)  ^r() and ^ro() accept parameters of the form "WIDTHxHEIGHT" and "WIDTHxHEIGHT±X±Y".

You can do things like vOTE5 with the new synatx..

Here is marker.xbm: marker.xbm
Those icons are very simple to make, I might make some more layout later.

That config doesn't seem to have any images with their full paths, ie ^i(/path/to/bitmaps/bitmap.xbm).

dzen is going to need fully-qualified paths to each image.

If you want xpm (full-colour) support, you'll have to patch that in yourself (I posted a pkgbuild somewhere in this thread).

Re: dzen & xmobar Hacking Thread

EDIT:
Graph support is now in the SVN version. No need for gcpubarG any more.
Check out the wiki entry for more details.

dz-grbig.png
gcpubar -fg grey50 -s graph -gw 12 -gs 1 -w 300 -h 62 -l '^i(cpuicon.xpm)' | dzen2 -h 64 -w 370 -ta l -bg black


-----------------------------------------------------------------------------

I just hacked up a first alpha version of graph support for gcpubar.

You need the latest SVN dzen version, and this modified version of gcpubar.

Compile it:

 gcc -o gcpubarG gcpubarG.c

Use it like:

 gcpubarG -i 1 -h 30 -w 120 -s 1 | dzen2 -w 120 -h 30 -ta l

Where '-s' is the amount of space in pixels between each graph value.

You can make graphs like these:
vOTIz
The upper graph runs with "-s 0", the lower with "-s 1".

Or integrate it in a statusbar:
vOTI1

Re: dzen & xmobar Hacking Thread

Indeed, that does look great.  I must admit I'm not a fan of bars or graphs because I feel my desktop space is at a premium already, but kudos for the additional feature.

Re: dzen & xmobar Hacking Thread

buttons, how did you get the updates/news notification?

does gcpubar support more than one core?

and what about mpc intergration?
-> did it with mpc | sed 1q | grep - (presumes that songs have a -)

oh and what about weather xpms?? buttons??

Re: dzen & xmobar Hacking Thread

I took the "many dzens" approach which allowed me to have a more active bar. redbeard_dzen.png

* Clicking on the workspace list takes you to that workspace
* Hovering over the title bar shows a full width slave for large window titles (note the ... here)
* Hovering over the |{KERNEL,MAIN,DAEMON}| displays a scrollable view of those log files
* Scrolling changes the volume and clicking toggles mute. (updated in realtime using inotify)
* Hovering over the weather displays the forecast
* Hovering over the system stats shows more (to be expanded later)
* Hovering over the clock shows `cal -3` (note that the "important" part of the time is highlighted to make is easy to see)

The only real problem I have (other than running out of pixels) is that the script doesn't quit cleanly. To reload it I have to run "killall dzonky dzen2 inotail watchfile inotifywatch ;sleep 1; dzonky". If anybody has some suggestions to work around this, I'm all ears. Also, i get segfaults if I use scrolling and ^cs(), but i use $EVENTSCLEARABLE to get around that for now.

dependencies:
svn copy of dven2 and gadgets
xte (a virtual keyboard in xautomation package)
inotifytools
inotail

I used the conky one that floats around these forums.  Here it is:

~/bin/dzen_updates.pl

#! /usr/bin/perl -w
use strict;
# November 15, 2006
# Daniel Vredenburg (Vredfreak)
# This is a program that checks for package updates for Arch Linux users.

open (MYINPUTFILE, "/var/log/updates.log") or die "No such file or directory: $!";

my $i = 0;
while(<MYINPUTFILE>)
{
        if (/^(.*)\/(.*)(\..*\..*\.)/)  {
                #print " \n";
                $i++;
        }

}
if ($i == 0) {
        print "up to date";
} else {
        print "available ($i)";
}
close(MYINPUTFILE);

Sometimes I change the print commands to alter the colour when there are updates available.

Then you need this in your /etc/cron.d/hourly directory:

pacsync.sh

#!/bin/bash

# This issues a command to 1. Sync the package database, 
# 2. Check for upgradable packages, 3. print the URL of any possible upgrade. 
# The output of our command gets written to updates.log, which we will use 
# dzen_updates.pl to parse to see if there are any available updates.

pacman -Syup --noprogressbar > /var/log/updates.log

Which will of course do a package sync each hour and put the results in /var/log/updates.log.  Make sure this is writeable by root and readable by you.

As I mentioned earlier in the thread, once you've signed up for weather.com's xml service they send you a link to a zip file containing everything you need, including xpms.  Then you'll need to open the 32x32 folder, and run the following command (courtesy of gotmor):

for i in *.png; do convert -scale 14x14 "$i" "${i%%.*}-scaled.xpm"; done

And then use these images when following the weather instructions from Rob's site.

Keep in mind you will also need to patch dzen2 to allow full-colour xpms.  For completeness, and because this post isn't nearly long enough yet, here's the PKGBUILD:

You need ImageMagick.

I'm having some trouble getting the new gcpubarG to work.
I wan't it to be a small rectangular graph like in gotmor's screenshot.  however
"gcpubarg -s g -w 200 -h 16 -gs 1 -gw 3" displays the usage options in the dzen statusbar and with just "gcpubarg" dzen doesn't even show up.

Executing "gcpubarg" on the command line gives the correct values I guess ("^fg(white)^p(1)^r(1x0+0-1" and so on).

gcpubarG is obsolete, you just need to grab the latest development version of dzen:

svn checkout http://dzen.googlecode.com/svn/trunk/ dzen

and use the gcpubar that comes with it.

Have a look at the Wiki entry for further details.
