This is icewm in Saluki

I've been sitting on this for awhile..

new svg based tempicon remove older versions first!!!

Excellent. Much easier to read thanks.

Hello Mick

Working OK in Slacko-531 (with Compiz + Lxpanel)

I installed lm_sensors-3.1.2 via the PPM then installed the tempicon-0.05.pet

Running the command: sensors-detect
revealed:

Code: Select all

AMD Family 10h thermal sensors...                           Success!
    (driver `k10temp')

but modprobing the module k10temp failed.

A quick 'google' lead me to these:

• http://khali.linux-fr.org/devel/misc/k10temp/Makefile
  http://khali.linux-fr.org/devel/misc/k10temp/k10temp.c

with which i was able to build the k10temp module.

I put it in: /lib/modules/2.6.37.6/kernel/drivers/hwmon/
ran depmod
then modprobe k10temp
rebooted and there it was in the system tray of lxpanel.

Nice one mate.

Minor update v-0.06 -see main post

Thanks CatDude, 06 fixes the version number. Yeah, 2.6.37.6 has k8temp which works with my X2 and nvidia board, I thought it would work for most, wrong I guess! Can you post your module please? I'll whack it in PPM.

Also, pemasu, it *should* install cleanly into woof now, I'll test tonight when I do a build. I left a message on your thread but I now realise it was doomed to fail!

Hi

...Can you post your module please? I'll whack it in PPM.

Here you go mate.

Does it work with Wary 500?

I have made a generic tool to do this using symlinks:
http://www.murga-linux.com/puppy/viewtopic.php?t=76431
you should be able to adjust your backend to only update a single file and the binary is smaller too.

edit: and here is an awk example that I used to generate the svg for my cpu

Code: Select all

#!/bin/ash
awk '{BG = "#00FF00"
if ($2 > 65) BG = "#FFFF00"
if ($2 > 80) BG = "#FF0000"
printf "<svg xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"> \
<rect width=\"32\" height=\"22\" x=\"0\" y=\"0\" \
style=\"font-size:%d;fill:%s;fill-opacity:0.75;fill-rule:evenodd;stroke-width:3pt;\" id=\"rect1\" />  \
<text x=\"0\" y=\"18\" style=\"font-size:%d;font-weight:normal;fill-opacity:0.75;stroke-width:3pt;font-family:helvetica;\" id=\"text1\"> \
<tspan id=\"tspan1\">%d°C</tspan> \
</text> \
</svg>",14,BG,14,$2}' /proc/acpi/thermal_zone/TZ01/temperature >test.svg

Tried this and I get:

Edit, nope that was just my browser formatting even though html standards told it not to.

the real problem was using the UTF-8 encoded '°' instead of the standard ascii one that I posted ... guess I need to push a tarball to avoid these copy-paste issues (unless maybe you added your own '°' ???)

btw if you ever need an ascii character, I use this a lot to cut/paste from the terminal

Code: Select all

int main() {  
char c=127;
while (c-->=-127) {  
  printf("%d, %c\n",c,c);
}
}

0.07 is out

Fixes persistent pink message recurrence.

See main post

[pemasu]

[01micko]

New version 0.09

See main post

-now compiles the source with a Makefile (devx needed for compilation, not for pet install)
-supports FatDog
-lm_sensors now optional (ymmv - reports please)
-README in source package
-new, rounded corners on icons
-icons are included in PET, no longer generated, faster on older HW
-some minor bugfixes

G'day 01micko,

A little off-topic maybe, but I'm curious why this interesting little utility was not in Slacko (or is it and I couldn't/can't find it)?

I have two computers using high operating temperature CPUs so like to watch how often they get over 70C and to see the background colour change from green to yellow/amber. I assume it would get to red if I find and run the "right" software.

Thanks for this latest version. With my 6 year old hardware I found that retaining lm_sensors displays more info. (i.e. max allowable CPU temp)

[technosaurus]

@micko I recently made an update to sit:
http://murga-linux.com/puppy/viewtopic.php?t=76431
It should work well with tempicon now that it just monitors each icon to see if it is modified via inotify and directly launches the left and right click apps (no need for a monitor loop any more).

Let me know if you are interested in using it. I think I have simplified it to the maximum extent possible (<20 lines of code) but would like some feedback. (for instance, would it make more sense to fork the click actions, so that icons continue to update while the click event is open?)

[01micko]

@techno

using sit2:

Code: Select all

#!/bin/bash
#set -x
# Records the CPU temp, calls "sit" to display in system tray
# depends: sit[2] (technosaurus http://murga-linux.com/puppy/viewtopic.php?t=76431)
# other unix: +gtkdialog

sit "$THEICON" "$TOOLTIP" "$LCLICK" "$RCLICK"

But of course the function 'infofunc' doesn't work (see edit), have to create a separate script for sit to call.

Playing with this exposed a bug in tempicon so I'll fix that soon, it's in the main loop.

Thanks

EDIT: working now

[01micko]

Version 0.10 is out.

There's one Q I will answer

A little off-topic maybe, but I'm curious why this interesting little utility was not in Slacko (or is it and I couldn't/can't find it)?

Not off topic at all, the reason is the stability. I wasn't quite happy with it, now I m a little more happy. V 0.06 is currently in the Slacko repo. This version will be taking it's place.

I'm hoping this one will build and run on the raspi platform. Since it is passively cooled temperature stats will be interesting.

[01micko]

version -0.11 is posted

-bugfix

The main loop refused to start after X restart or restarting the prog manually

Thank you for a great program.
I wanted you to know that it works well with Saluki 23 that has the latest xfce desktop and panel.

I was wandering. Is there a way to change temp to Fahrenheit?

Pete.
