If using two or more instances of dzen, I've found redbeard0531's script to be very useful. So whether you do it this or that way, it's all in this thread. But I also know it's not that obvious if just browsing through the pages

How do I get different sleep timers for different things? I want a 1 second timer on my eth0 monitor, and a 60 second timer on my Gmail notifier.

You can also use the multiplexer (dmplex) for this task.

Actually there are lots of ways to implement that functionality either in a polling or event based way...

I've been trying out redbeards dzonky script...but i find that it has a memory leak. for example if i leave the script running overnight, i'll wake up to ram usage of 1.8GB out of 2GB total and X usually frozen.

not sure if you're experiencing this or not, i did modify his script a bit tho. so it may have been my fault.

That's a problem with dzen-svn. It's a resource leak (using xrestop you can verify this yourself if you like).

Right, that was a problem with a particular SVN revision but it's fixed since several revisions.

alright cool...
having trouble building the latest dzen2-gadgets-svn package from AUR using yaourt:
my output:

http://pastebin.archlinux.org/26792

sed: -e expression #1, char 26: unterminated `s' command
Error: Makepkg was unable to build dzen2-gadgets-svn package.

not sure as i dont see any sed expressions in the PKGBUILD file.

Maybe u could try compiling it without yaourt, it works fine for me.

Thanks for the reply, it works

Do you pronounce dzen using one syllable or two ("D-Zen")?

Alright i got the newer svn version running and the memory leak seems to be fixed. thx for the infos

The volumeter from the wiki doesn't work right anymore with the latest dzen.

The weather script, very interesting, but is this feature through weather.com only for us. residents?
I've registered but I can't seem to find the correct customer ID/KEY...

Yea I'm using the weather.com script thingy, but how do I change it to English units ? Farenheight specifically.

wyvern · 2008-03-17 21:21:16

Okay, here's another embarrassed-newbie-at-the-scripting-of-dzen2 problem.

Well, I was okay; had a nice setup using conky | dzen2, but then I *had* to go and try my hand at dmplexing everything...

What am I doing wrong here? I start the following script running in the background, and in my .xinitrc I have 'tail -f /home/sapphire/.dzenpipe | dmplex | dzen2 -e 'entertitle=uncollapse;leavetitle=collapse' -x '0' -h '18' -ta l -bg '#000000' -fg '#ffffff' -fn '-*-terminus-*-r-normal-*-*-120-*-*-*-*-*-*' -u &'

#!/bin/sh
MOC='/home/sapphire/.moc/stats | fold -w60 -s'
TITLE='/home/sapphire/.moc/stats2 | fold -w40 -s'

echo "1 `conky &`" > /home/sapphire/.dzenpipe
echo "2 (echo '^tw()^fg(#a6b38d)^i(/home/sapphire/.dzen/xbm2/mpd.xbm)^fg(ffffff)^fn(-*-fixed-*-*-*-*-10-*-*-*-*-*-*-*)^p(5)`$TITLE`'; while true; do echo '^p(5) ^l(2)`$MOC`'; sleep 20; done)" > /home/sapphire/.dzenpipe

And yes, I have made the appropriate pipe

All I get is the dzen bar running, no output to it at all. In the console I tested it from conky is also running, but not outputting to the 'bar.

It's something blindingly simple, (probably all in the syntax), but I am at a loss here All help is appreciated.

redbeard0531 · 2008-03-17 21:34:26

the echo lines wont work as intended. to get the effect you want insert this awk command into your pipeline, replacing 1 with the number you want prefixed to each line.

 <in_command> | awk '{print "1", $0}' | <out_command>

example:

conky | awk '{print "1", $0}' > /home/sapphire/.dzenpipe &

Ah... I tried this exactly, commenting out the other lines to see if worked at all. It doesn't.

Am I just being incredibly dense at this point, or is there something more I should be doing? (And if I don't reply today, I've gone to get some much-needed sleep - can you tell I'm tired?)

Thanks again for your help.

Hey.

Due to massive spam attacks I had to move the dzen wiki to an engine that allows better authentication.

The new Wiki can be found here:
http://dzen.geekmode.org/dwiki/doku.php

Have fun, Rob.

Hello,

I trying to use conky-cli with dzen2 and I'm having problems.

I want to use some of the wireless variables that conky has but they seem not to work in the cli version.

I notice when compiling cli (what i presume) wireless support is not compiled in. If this is true how can be turned on?

The variables that I want to use are wireless_link_qual and wireless_essid.

Thanks,
brncmp

Add wireless_tools to the depends line. depends=('glib2', 'wireless_tools')
And add --enable-wlan to the configure line. Update the md5sum: makepkg -g >> PKGBUILD and then recompile.

semdornus · 2008-04-17 04:06:20

I don't use it myself, but I stumbled across a Twitter client for dzen (written in Haskell) and I thought people might like to know.
dtwitzen with short description in (broken) English can be found on this page: http://eof.jp/dtwitzen/
For those who read Japanese; a small blog post from the author describing it here: http://d.hatena.ne.jp/smly/20080304

brncmp · 2008-04-17 11:19:48

THANKS semdornus,

That works great, just what I wanted. How did you know to use --enable-wlan? I couldn't find that argument any where.

anyway thanks again,

brncmp

You can (usually) find out all the available options of a program, after you've downloaded and extracted the source,
by doing "./configure --help" in that directory. (Sometimes you have to run autogen.sh first).

Of course you can also take a look at the PKGBUILD of the official package or use a Google query.

I've run into some trouble with dmplex and I was wondering if anyone could give me some advice. I realized that the only use I really had for a tray is pidgin message notification and I figured that I might as well use dmplex and pidgin to do it. I found this plugin that seems to do what I want, more or less. I made these modifications to be able to specify what and where to write it. Problem is, my dzen bar goes completly crazy as soon as I enable the plugin and start sending stuff to the fifo pipe. Could someone give me some pointers on what I am doing wrong and why dmplex gets confused by the pidgin plugin.

Can you provide some sample input that you feed to dmplex?
