Title: ondemand script (unsupported)
Post by: jls on April 15, 2010, 11:31:39 PM

this modified version of the ondemand script includes:

the extension is dowloaded from the net if it's not present in local
the eventual argument passed to the ondemand item will be passed to the actual program
the eventual <extension>.desktop file is modified to launch the ondemand item instead of the actual program

Title: Re: ondemand script improved
Post by: jls on April 16, 2010, 10:52:11 AM

second version of the script, changelog;

the extension is uninstalled (only if it has a desktop entry and it's mounted) when the app is closed, but the .desktop file remains
the .desktop is added to filetool

look in the attachments: there is also the tcz-uninstall script

modified again

Post by: jls on April 17, 2010, 06:41:11 PM

other changes:

if jwn menu entry doesn't exists, the script checks if there is the .desktop in order 2 know the binary name
after the app is used also the eventual corrsponding locale extension is unmounted ( doesn't work if the extension was copied 2 the file system)

note that the tcz-uninstall script is attached in the second post

I modified again this script:
if an icon is found in the tcz, yaht is placed in ~/.local/share/pixmaps and the Icon field in the .desktop has the name of the icon.
If the tcz is not found locally is downloaded from the net.
Optional dep: flnotify (a message is shown while dowloading from the net the extension).
A diff file is attached to this message
