a cmg in a .desktop file(alpha release)!

Unfortunately, I get the error: Unknown host bcvrf.yahoo.com

Perhaps you can use a smaller application, let's say klik://xvier for demonstration (it's only a few KB in size)

I probably still don't fully understand how you do it, but one thing would be of extreme importance to me: that you can freely move the "1 file" to whatever location you want, and that it does not need to unpack itself before the application can run.

it can be place any where.
because every time you click the .desktop file it runs the Run.sh script that search for the file(it send to the Run.sh script the name and the rNum(a random number created at creation of .desktop file).
this is the Run.sh script:

Code:

#/bin/sh
#get the random number $1=filename $2=random number fPATH is the searching path
fPATH="/home"
files=$(find $fPATH | grep $1)
for filex in $files
do
rNum=$(head -n 2 $filex | tail -n 1 | cut -d" " -f2)
if [ $rNum = $2 ]
then
	$filex
fi

done

Question: why this forum doesn`t have attachments?

i made a .desktop file of xvier here:

http://easy.savefile.com/urielka/xvier.zip

just unzip copy the Run.sh script to /usr/bin and chmod +x him
and then click the xvier.desktop file!

Note

on`t change the name of the file changing it will make the file unrunable
Note2

on`t enter Properties of the files it will make it corrupt
Note3: the file must be in the path of /home(including all the subdirectorys) if you want it to be any where set the fPATH in the Run.sh to /(i don`t recommend it coz it will take alot of time).
Note4: the Run.sh is not finished,when i finaly finish it ,it will have multiplie path and index searching for more speed.

More to come!!!

Looks like a clever idea, but I would change it a bit:

- The logic for mounting should still be outside of the cmg, e.g., in ~/.zAppRun, because it's not really stable code yet and should be easy to upgrade anytime w/o having to rebuild all cmg files

- Why the GUIDs? That looks "Windowsy" to me. What do you think about the following, it basically calls "itself":

Code:

#!/bin/sh
Do_Nothing ()
{
[Desktop Entry]
# for the specs
# see http://standards.freedesktop.org/des...t/ar01s06.html
Exec= sh -x %k # tail +9 %k | sh # skips the first 9 lines but removes $0
Icon=info
Name=Self-contained test application
Name[de]=Selbstablaufendes Testprogramm
Type=Application
Terminal=true
}

#
# How to insert icon data into this file?
#

#
# here a shell script can be inserted
#

#
# below this, the cramfs image could be appended
# to be mounted from ~/.zAppRun with loop offset
#

about the :

Code:

sh -x %k # tail +9 %k | sh

did you tested it?
because as far as i know the $0 when running a .desktop is kdesktop(because kdesktop run it).

about using ~/.zAppRun it`s ok but it should contain at least a simple script that will run the ~/.zAppRun like this:

Code:

#!/bin/bash
~/.zAppRun *  #this script runs on the cmg directory by default!

EDIT: i readed the specs now and i understood how it work and i must say : how the hell did you find this?! i looked at the specs about two hours and i didn`t saw this little (but very important) info.
i will update the scripts and post them very soon.
but for the time i will post a updated xvier using the code that you gave!.(uning sh -x %k and ~/.zApprun instead of using the zApprun inside the .deksktop)
here is it:

Exec=sh -x %k
works *perfectly* for me

Do you know a way to calculate the neccessary offset= value for loop?

Btw, would be great to see you on #klik on irc.freenode.net

**probono** · 05-28-2005, 06:13 PM

This works:
(Only .zAppRun has to be changed so that it calculates and uses the correct offset= parameter when loop-mounting)

Code:

#!/bin/sh 
Do_Nothing () 
{
[Desktop Entry]
# for the specs see
# http://standards.freedesktop.org/des...t/ar01s06.html
Exec= sh -x %k 
Icon=info
Name=Self-contained test application
Name[de]=Selbstablaufendes Testprogramm
Type=Application
Terminal=true
} 

#
# How to insert icon data into this file?
#

~/.zAppRun "$0" 
# we need to have .zAppRun calculate and use offset=

#
# below this, the cramfs image is appended
#

Now this is a bit of "cheating" because it unpacks the application before it runs it (requires disk space ram, and slows down the start of large apps considerably). So we should really try to use ~/.zAppRun and cramfs/zisofs - what do you think?

it`s uncommpresd tar so it doesn`t take so long(i think a 0.01 secs) but using the ~/.zAppRun and cramfs should be faster but you can`t have both the icon and the cmg.
with my "cheating" you can tar the cmg+script+icon and then in the script check if the icon exsist on(let say) ~/.kde/share/icons/klik/icon1.png and if it doesn`t exsist it will copy the icon to ~/.kde/share/icons and the run the cmg.(of course the Icon= will be Icon=~/.kde/share/icons/klik/name_of_app.png)
