Unfortunately inotify doesn't work on sysfs AFAIK, thus the polling.
You could adapt pup_event* similar to how scottman did in akita. Akaskrawal may have a better method though. He wrote a standalone drive monitor in c using glib/gio.

I only put one function in /usr/share/sit/... feel free to add your own to that file so you don't need to use the -i parameter.

FYI puppy has inotifyd (from busybox) that can do the same stuff for your sit scripts.

RE drive icons - rather than changing the .DirIcon in $HOME/.pup_event/* Barry has a function in /etc/rc.d/functions4puppy4 called icon_{un,}mounted_func that guts $HOME/.config/rox.sourceforge.net/globicons
(note that I am using $HOME vs /root - why intentionally make your scripts unportable? ... even ~ would be better than /root)
short answer - you can modify /etc/rc.d/functions4puppy4 to (additionally or instead of) put the icons somewhere. (long answer is left as an exercise for the reader)

I was just poking around on gtkdialog to try and replace libglade with gtk's builtin gtkbuilder (displays, but actions didn't work). If I ever figure out how to connect the callback functions I may add support for using gtkbuilder ui files (XML built with glade-3) if anyone is interested in using a GUI RAD to put together their UI rather than hand coding XML and having to call gtkdialog.

Here's a short prototype for recognizing and showing an icon in the tray when a usbdrive is inserted. It utilizes an "inotifyd" command line which should be evoked at startup. Inotifyd monitors the file "/proc/partions" for any changes. and then using Technosaurus's sit, places an icon in the tray with a tooltip showing the drive name and size. The "mountcode -$dr" for the left click is just pseudocode. The following script should be put in $HOME/usb-watch.

good thinking about /proc/partitions - I assume that when /proc/partitions changes you look at /sys/block and/or /proc/mounts in the other script?

I was trying to understand how to use gtkbuilder, so I decided to throw together something similar to sit just to figure it out (just because I am familiar with that chunk of the api already). I could probably cut some code here and there, but there was absolute crap for examples, so I cobbled it together enough to make it work. All you need to do is create a gui in glade-3 (status icons are near the bottom) and add handlers to activate (left click) and popup (right click) ... puppy's glade doesn't support tooltips though

Ok, apparently "inotifyd" will not monitor /sys/block . (Maybe because of the kernel filesystem?). So here's another version using /root/.pupevent.

Unfortunately it can only do one usbdrive at a time because I don't see any way to link a specific icon when multiple sit icons are in use.

Below goes in "usr/share/sit/functions.sh"

In case anyone was looking to make their applications portable to windows

this was built with mingw and http://ftp.acc.umu.se/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip
gcc -Os sit.c -o sit.exe -std=c89 -Wall `pkg-config gtk+-2.0 --cflags --libs` -s

Since there are libraries for many languages to handle xml code parsing, I was wondering if any xml help existed for shell programs in Linux and ran across this -
http://xml-coreutils.sourceforge.net/

It's a set of utilities aimed at emulating the standard shell text tools like sed, tr, cat, printf, find, etc... but specifically for xml.

I compiled xml-printf which can be used to capture the content between tags and made a tray icon program for weather.

Tweather takes information from rss.accuweather.com by zip code and displays the current weather icon in the tray. When the mouse is moved over the icon, current conditions are displayed and the forecast for tomorrow. A left-click of the icon refreshes the data and a right-click quits the program.

You'll need to edit the zip code at the top of the script for the zipcode you want to monitor.

Tweather requires Technosaurus' sit program found here-
http://www.murga-linux.com/puppy/viewtopic.php?t=76431&start=70
and xml-printf which is in the attached xml-printf.tar.gz file. EDIT: see next post with a much smaller version kindly compiled by Vovchik

Probably best used by linking the tweather script to the /root/Startup folder so that it's available at the start.

Cheers,

Dear seaside,

Happy New Year, and thanks for tweather and xml-print. I stripped your version and then upx'd it, reducing the size from 233k to 33k. I wish I knew how I could get tweather to show Vienna, Austria and Lviv, Ukraine. I don't know where to find the source xml file on accuweather. Have any ideas?

With kind regards,
vovchik

Dear seaside,

I installed your pet and it works nicely. I have also checked that link you provided for RSS feeds. Yahoo seems to cover the globe. To get Vienna, Austria, and centigrade, I use this:

I just posted some new svg tips for slicing png images in the
simple svg game framework thread
This allows you to use a single slice-able png image for all of the sprites (better for file size and for http requests if they are served online)
The tray icons are pretty small so I didn't think this would be relevant but it seems that some weather apis use png sprites to combine clouds, rain, sun, etc... into 1 image so that it can be downloaded all at once (this only requires 1 http request, so it is usually faster) and formatted using to the correct slice using css

I also wrote a sprite generator here:
