[digiKam-users] Execute a custom script on folder

[hleroy]

In my workflow, I keep RAW files only for the photos I have rated. I have
written a small script which I run from the terminal. It checks with
Exiftool if the JPG photo is rated. If yes, it moves the corresponding RAW
file to a subfolder. Then it deletes the remaining RAW files.

Is there a way to execute a custom script (bash, python,...) *on an album*
from the Digikam interface ? i.e. calling the script and passing the album
path as an argument to the script.

Thanks

Below the script in case someone has a similar need.

#!/bin/bash
#
# This script will delete all Raw (CR2) files when the corresponding JPG is
unrated.
#
# The purpose is to keep only Raw files for photos which are worth it
# (assuming you have gone through the effort of rating them)
#
# **WARNING**
# Make sure to be in the right folder before running this script,
# because it will trash all Raw files with no matching rated JPG
#
# Requires:
#   exiftool
#   trash-cli

# Check requirements
hash exiftool 2>/dev/null || { echo >&2 "I require exiftool but it's not
installed.  Aborting."; exit 1; }
hash trash-put 2>/dev/null || { echo >&2 "I require trash-put but it's not
installed.  Aborting."; exit 1; }

# List all rated JPG file in current folder
RATED_JPG=`exiftool -m -if '$Rating' *.JPG  -q -p '$FileName'`

# Create 'Raw' sub-folder if it doesn't exist
if [ ! -d Raw ]; then
  mkdir Raw
fi

# Set line break as field separator and loop throuh all rated JPG files
IFS=$'\n'
for JPG in $RATED_JPG
do
  CR2=${JPG::-4}'.CR2'

  if [ -f "$CR2" ]; then
    echo 'Moving '$CR2
    mv $CR2 Raw
  fi
done

# Trash remaining Raw files in current folder (needs trash-cli package)
#trash-put *.CR2

Hi!

a "dirty hack":
I use "Open With" from the context menu (rightclick) of a photo to manipulate
this photo with a custom bash script. In this script, you could use "dirname"
(see https://stackoverflow.com/a/6121114/1098572) to extract the directory of
the pictures path. Then you could process this directory.

=> you don't rightclick a album, but any picture in this album to process the
whole album.


How To add your script to the "Open With" dialog of KDE:

1. create a desktop-file, like: "myRawCleaner.desktop" and put it in:
     ~/.local/share/applications
  or /usr/local/share/applications

2. content of "myRawCleaner.desktop":
----------------------------- 8< -----------------------------
[Desktop Entry]
Name=myRawCleanScript
GenericName=general description
Comment=Some comment
Icon=resizeimages
Exec=/usr/bin/konsole --noclose -e /bin/bash /usr/local/bin/rawCleanScript.sh %F
Type=Application
MimeType=image/jpeg
Terminal=false
----------------------------- >8 -----------------------------
I guess, you have to change "MimeType=image/jpeg" to something matching your RAW
files.

3. Now digiKam should show "myRawCleanScript" in the context menu of your RAW
files in the "Open With"-submenu.

Hope this helps.

Regards,
        Peter

Nice hack Peter. It worked perfectly.

For those interested, the files:

~/.local/share/applications/myRawCleaner.desktop

[Desktop Entry]
Name=Keep CR2 for rated photos
Exec=/usr/bin/konsole -e /bin/bash ~/Scripts/keepRawForRatedPhotos.sh %F
Type=Application
MimeType=image/x-canon-cr2
Terminal=false


~/Scripts/keepRawForRatedPhotos.sh

#!/bin/bash
#
# This script will delete all Raw (CR2) files when the corresponding JPG is
unrated.
# The purpose is to keep only Raw files for photos which are worth it
# (assuming you have gone through the effort of rating them)
#
# It requires a filename as argument. It is meant to be called through a
"context menu"
# (right-click) on a picture
#
# Example .desktop file for KDE (to be placed in
~/.local/share/applications/myRawCleaner.desktop)
#  [Desktop Entry]
#  Name=Keep CR2 for rathed photos
#  Exec=/usr/bin/konsole -e /bin/bash ~/Scripts/keepRawForRatedPhotos.sh %F  
# <-- adjust the script location here
#  Type=Application
#  MimeType=image/x-canon-cr2
#  Terminal=false
#
# **WARNING**
# Make sure to be in the right folder before running this script,
# because it will trash all Raw files with no matching rated JPG
#
# Requires:
#   exiftool
#   trash-cli

# Check that first argument is a file, then extract folder name
if [ -e "$1" ]; then
  ALBUM=$(dirname "$1")
else
  # Otherwise exit
  exit 1
fi

# Check requirements
hash exiftool 2>/dev/null || { echo >&2 "I require exiftool but it's not
installed.  Aborting."; exit 1; }
hash trash-put 2>/dev/null || { echo >&2 "I require trash-put but it's not
installed.  Aborting."; exit 1; }

# List all rated JPG file in the folder
cd "$ALBUM"
RATED_JPG=`exiftool -m -if '$Rating' *.JPG -q -p '$FileName'`

if [[ -z "$RATED_JPG" ]]; then
  echo "No rated photos"
else

  # Create 'Raw' sub-folder if it doesn't exist
  if [ ! -d Raw ]; then
    mkdir Raw
  fi

  # Set line break as field separator and loop throuh all rated JPG files
  IFS=$'\n'
  for JPG in $RATED_JPG
  do
    CR2=${JPG::-4}'.CR2'

    if [ -f "$CR2" ]; then
      echo 'Moving '$CR2
      mv $CR2 Raw
    fi
  done

fi

# Trash remaining Raw files in current folder (needs trash-cli package)
trash-put *.CR2

# Wait for a key press before exiting
read -n 1 -s -r -p "Press any key to continue"

Right click hack wouldn't work in Windows would it?
