OK, enough with the alpha versions and on with the release candidates.

                   by default it looks in /usr/share/sit/functions*
  image        full path to image file
  tooltip      full path to tooltip file or a "quoted tooltip"

I haven't been working on the drive stuff, but the biggest difference is that now it needs an extra parameter for a tooltip (mouse-over message) after the icon, but before the click actions. This is a good place to put what each mouse button does or any useful information - this can be a path to a text file that you can update or an unchangeable string

Here is the svg code for an network transmit/receive app:
path1 is for receive, path2 is for transmit
Code:
<svg width="48" height="48" id="svg1" xmlns:xlink="http://www.w3.org/1999/xlink">
<image xlink:href="/usr/share/midi-icons/www48.png" width="48" height="48" id="image1"/>
   <path id="path1" style="fill:#00FF00;fill-opacity:0.6;stroke-width:0;"
      d="M 46.5,17.8 L 36.8,29.0 L 27.2,17.8 L 32.1,17.8 C 33.7,13.4
      30.4,10.6 26.5,10.6 C 23.7,10.6 19.9,12.1 18.6,15.9 C 18.0,17.9
      16.8,17.0 16.8,15.3 C 17.0,8.7 21.9,3.4 29.3,3.4 C 36.6,3.4
      42.1,9.1 41.7,17.8 L 46.5,17.8 z" />
   <path id="path2" style="fill:#00FF00;fill-opacity:0.6;stroke-width:0;"
      d="M 1.5,30.2 L 11.2,19.0 L 20.8,30.2 L 15.9,30.2 C 14.3,34.6
      17.6,37.4 21.5,37.4 C 24.3,37.4 28.1,35.9 29.4,32.1 C 30.0,30.1
      31.2,31.0 31.2,32.7 C 31.0,39.3 26.1,44.6 18.7,44.6 C 11.4,44.6
      5.9,38.9 6.3,30.2 L 1.5,30.2 z" />
</svg>


and a very basic implementation with no calculations or anything like some existing ones do (should be easy enough to add though):

lobo115,

Ah, yes --that question was when sit was using inotify which it no longer does. It's possible to do this with another program, "inotifyd" to watch for activity.

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.

Subject description: Detect usbdrive insertion
 

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.

Cheers,
s
Code:

#!/bin/sh
#$HOME/usb-watch
# inotifyd $HOME/usb-watch /proc/partitions:c   # put line in startup script

usbdrv="sd[a-z][1-9]"
tooltip=`tail -1 /proc/partitions | awk "/$usbdrv/"' {print $4};{printf("%.2f",$3/1024/1024); print "GB"} '`
[ -z "$tooltip" ] && exit
drv=($tooltip)
sit /usr/local/lib/X11/pixmaps/usbdrv48.png "$tooltip"  "mountcode -$drv"

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


Code:
#include <glib.h>
#include <glib-object.h>
#include <gtk/gtk.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

gchar *incfiles="/usr/share/sit/functions*";

   if (!g_spawn_command_line_async(s,NULL)) {
      gchar *buf=g_strdup_printf("for x in %s; do . $x; done ; %s",incfiles,s);
      popen(buf,"r");
      g_free(buf);
   }
}

static void leftclick(GtkStatusIcon *si, gpointer s){
   (s==NULL) ? (g_print("left click on status icon\n")) : run(s);
   g_print("l:%s\n",s);
}

static void rightclick(GtkStatusIcon *si, guint b,guint a_t, gpointer s){      g_print("r:%s\n",(gchar*) s);

technosaurus,

Yes , much better to monitor /sys/block for specific directory changes than examining the single file /proc/partitions for specific content changes (difficult to say what went missing Smile )

PostPosted: Tue 02 Oct 2012, 12:25    Post subject: Usbdrive icon in tray  

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"
Code:
mountcode() {
# left click function mountcode

 [ ! -e /tmp/drv-pid ] && exit # nothing to mount or unmount
tdrv=`cat  /tmp/drv-pid` # check drive status
tdrv="${tdrv% *}"
if grep $tdrv  /proc/mounts; then
   umount /mnt/$tdrv
   if [ $? -eq 0 ];then
      rmdir /mnt/$tdrv
      ln -sf /usr/local/lib/X11/pixmaps/usbdrv48.png /tmp/drv-icon
      FILEMGR="rox -D"
      $FILEMGR /mnt/$tdrv
   else
      Xdialog --title "WARNING" --msgbox "Sorry $tdrv did not unmount" 0 0
   fi

else
   FILEMGR="rox -d" #eg.. xfe #
   TYPE="$(guess_fstype /dev/"$tdrv")"
   [ ! -e /mnt/$tdrv ] && mkdir -p /mnt/$tdrv
   mount -t $TYPE /dev/$tdrv /mnt/$tdrv
      if [ $? -eq 0 ];then
       ln -sf /usr/local/lib/X11/pixmaps/usbdrv_mntd48.png /tmp/drv-icon
      $FILEMGR /mnt/$tdrv
      else
         Xdialog --title "WARNING" --msgbox "Sorry $tdrv did not mount" 0 0
      fi

fi
}   


Place script "usb-watch" below in $HOME/usb-watch
Code:

#!/bin/sh
#  # inotifyd $HOME/usb-watch /root/.pup_event:nd # in startup

#echo $1  $3
 
if [[ $1 == d ]] ;then
   pdrv=`cat  /tmp/drv-pid`
   pdrv="${pdrv#* }"
   kill "$pdrv"
   
   rm -f /tmp/drv-pid
   rm -f /tmp/drv-icon
   exit
fi
usbdrv=$3
usbdrv="${usbdrv#*_}"
[[ ! $usbdrv == sd[a-z][1-9] ]] && exit
ln -s /usr/local/lib/X11/pixmaps/usbdrv48.png  /tmp/drv-icon
sleep 1 # need time for diirectory to show in ./pupevent
tooltip=` awk -v i=$usbdrv '/<Summary>/ {print" " i"\n"" "$2,$4}' /root/.pup_event/"drive_$usbdrv"/AppInfo.xml |cut -d"<" -f1 `
sit /tmp/drv-icon "$tooltip" "mountcode"  &
pid=$!
echo "$usbdrv $pid" > /tmp/drv-pid

And the line "inotifyd $HOME/usb-watch /root/.pup_event:nd" needs to be started.

Cheers,
s

Yes, I tried that. That's why I was glad to hear that it worked on /proc/partitions - that meant we could monitor something that would tell us when to look in /sys/block, but I couldn't get it to work on /proc/partitions myself.

technosaurus,

It looks like you're right, it doesn't work in /proc/partitions either (or at least not today Smile ) So .pupevent is it.

Regards,
s
(I did the testing by faking a change to the /proc/partitions file instead of repeatedly plugging and unplugging a usb drive)
