Help: Removing line breaks unconditionaly in TAGS and returning new TAG name

[Joao]

Hi there,

I have just started using ExifTool and I am really happy to have found this amazing tool. Unfortuantelly, I am dealing with an issue for which I appriciate your help.
I got a large number of images and other files in a folderstructur which may contain line breaks in the following EXIF tags:




• Caption-Abstract               
  Description                 
  Image Description               
  Keywords                       
  Subject   

I do not need to change any EXIF data, I only need to extract the tags from the files as a CSV using the option:   exiftool -config ExifTool_config -a -csv -G1 -s -r --Keywords  s:\ >"output.txt"
I found this solution:

https://exiftool.org/forum/index.php/topic,1962.msg8559.html#msg8559
But it does not work for me, unless there is a line break in the tag, otherwise it is not displayed in the output.
I was hoping to ignore all tags with line breaks and instead using all the new tags which I generated using the config file

Example:

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::Composite' => {
        'NEW Description' => {
            Require => 'Description',
            ValueConv => '$val =~ s/[\n\r]+/ /g ? $val : undef',
        },
        'NEW Subject' => {
            Require => 'Subject',
            ValueConv => '$val =~ s/[\n\r]+/ /g ? $val : undef',
        },
        'NEW Keywords' => {
            Require => 'Keywords',
            ValueConv => '$val =~ s/[\n\r]+/ /g ? $val : undef',
        },
        'NEW Caption-Abstract' => {
            Require => 'Caption-Abstract',
            ValueConv => '$val =~ s/[\n\r]+/ /g ? $val : undef',
        },
        'NEW ImageDescription' => {
            Require => 'ImageDescription',
            ValueConv => '$val =~ s/[\n\r]+/ /g ? $val : undef',
       },
    },
);

My question is, how can I modify this config file, so that regardless a line break or not in a tag, the NEW tag is generated in the output?


Thanks for your help in advance!

Good for you for searching through the archives.  But that post is outdated and exiftool can now do global arbitrary string processing with the -api Filter option.

To replace 1 or more CR/LF with a single space (as you show in your user defined tags), you can do this
exiftool -a -csv -G1 -s -r --Keywords  -api "Filter=s/[\n\r]+/ /g" s:\ >"output.txt"

This is great, it solves my issue.
