[digiKam-users] Is there a way to run an external program/script on selected images?

[Chris Green]

As per the subject, I want to run a script on a collection of images,
can one do this with Digikam?

I've found the Batch Queue Manager and one can use a "user shell
script" with that.  So is the interface documented anywhere - i.e.
how are the file names presented to the script and how should they be
returned?

Hello Chris,

if you are on KDE, you can create a (python) script and register this in your
desktop environment for the mime type JPG. In digikam select some images and
click "open with" > "your script" from the context menu.
This will start your script and pass the paths of all your selected images to
your script as parameters. I use this very often in my digikam workflow.

Regards,
        Peter

I'm not KDE (one of the disadvantages of Digikam for me, it pulls in
quite a lot of KDE stuff still) but I would think I could do something
like the above on xubuntu by setting the mime type as you say for JPG.

I'll try it, thanks.

Try right click on a file or a group of files - open with - others - type in "terminal - e /path/to/your/script.sh %U"

you might want to replace "terminal" with the name of the terminal emulator you use but I think it is called "terminal" in xubuntu.

I also add '--no-close' option to review the output printed in the terminal before closing it.

I am not sure if such option exists in xubuntu terminal but you can try.

I use xterm as a terminal for digikam scripts in Ubuntu, so it should work as
Xubuntu as well.

/xterm -e /path/to/script.sh %U/

where %U is a list of the filenames of selected pictures that are passed as
arguments to the script.

Excellent, thank you, that's a solid place to start from and I can
customise etc. as I need.

This doesn't work as expected.  What happens (on my xubuntu 18.04
system running Digikam 5.9) is that the script is called once for each
selected image with the parameter being the file name.  I.e. I don't
get the script called with "a list of the filenames of selected
pictures".

Is this a bug or as designed?

... and 'Batch Processing' seems to do exactly the same thing, i.e. if
I add some images to the queue in the Batch Queue Manager and then run
a User Shell Script the script gets run separately for each image.
This is not a lot of use if one wants to open a program with a list of
images.

Is there no way to select a number of images and output the list of
their filenames so it can be fed into some other program?

A bit of googling lead to this:
https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html

As you can see there, there's a difference between "%U" and "%u". Are you sure
you used the uppercase version?

[woenx]

That's weird.

Yes, I am sure i'm using the capital %U, I just checked again just in case.
This is the command I use:

xterm -e /home/user/Desktop/whatsdate.sh %U

And here's the script I use:
https://pastebin.com/8qCG3csG

It sets the EXIF date based on the selected pictures filename (e.g.
IMG_20180403_2315.jpg would set the EXIF date to 2018-04-03 23:15).  You can
modify whatever it is inside the

for i in "${arguments[@]}"
do

and it should apply that code file by file from the list of selected
pictures.

I thought I was replying to Chris Green, who did *not* get the whole file list
as parameter for the script. The behaviour you described is what's expected
with "%U". From the link I posted earlier:
| %u A single URL. Local files may either be passed as file: URLs or as file
path.
| %U A list of URLs. Each URL is passed as a separate argument to the
executable program. Local files may either be passed as file: URLs or as file
path.

Yes, I thought I was replying to Chris Green as well, but I saw my mistake
right after I sent the message. Sorry.

Anyway, I just wanted to provide an example that works under ubuntu 18.04.
The script can be easiky tweaked for whatever purpose is necessary.

Did you try %f or %F ?

Did you try a different terminal emulator ?

xterm should be good though.

I don't think this is the problem.  I have the file association for
JPEG set up to run a script.

If I select a number of files in my file manager and open them (with
the default application for JPEG) then one instance of the script gets
run with all the names as an argument.

If I "Open with Default Application" in Digikam I get my script
started up once for each image with one name as an argument.

The desktop file for my script has:-

    Exec=/home/chris/.cfg/bin/setmeta %U

It wouldn't matter for marcpaulus's case though, whether his script
was called several times with one file name as the parameter or once
with several file names as the parameters it would still work.
