Bash code to get icon locations in ROX's PuppyPin.

[sunburnt]

I'm adding to my script "rox-pinbd" that adds & removes ROX desktop icons.
I need to get the bottom icon "y=" in a column of icons made of a range "x=".
The ranges that define "x=" columns are 96 apart: 0-95, 96-191, 192-283, etc.

So for an icon at the left of the screen, the "x=" value would be: 0-95, &
the "y=" value would be the largest number or the bottom of the column.

This allows to find the next icon's "y=" value at the bottom of a given column.
It's compared to the screen resolution's Vert. value to see if there's enough room.
If the calculated position is off the bottom of the screen, then test the next column.

This gets the next on screen empty spot to place the next icon,
the column "x=" value & it's empty bottom position "y=" for the new icon.

Basically filter PuppyPin for a range of "x=" to get the column, & then the
largest "y=" value to get the bottom icon in that column.
That's subtracted from the screens Vert. value to see if there's enough room.

I've written most of a long complex set of Bash code lines to do this...
Is there a better way to do this in a script, maybe awk?

here is a script.
It looks for the highest y value, and prints the highest x value in this line.

But it will not work correct, if they are not arranged exactly on one line.
Lets say you have an icon at 10,60 and one at 70,58

then my script would report 10 60.
If you would place an icon right to it, it would cover the second one.
So that had to be refined.

But it might work, to position an icon under all other ones.

else
  print "new  position: " & highestx , newy
end if

here, this might be better.

It tries to find a free position inside the icons, not just at the end.
I did not check it carefully, as I run enlightenment without rox, but according to the coordinates it gives me, it might work.

It simply cycles through the screen using "squares" of 64x64, and looks, if an icon is positioned there already.

Thanks MU; It's good to hear from you again...

I thought of a script like your last one... a fill in the holes type, but it
seemed even harder than just finding a bottom one that'll fit on-screen.

I'll test the second one first, as it's more sophisticated, & it may not need
to factor in the screen resolution to insure the icon's not off in the ozone.
