[ALREADY IMPL.] Variable formatting - categories - has value: Can we have an "else" option?

[Ferdinand]

Regarding the option to format a categories variable, like {File.Categories.Direct} with a hasvalue option, like {File.Categories.Direct|Filter:Where; hasvalue:This file has a Where category}.

Would it be possible to have an else option, so that if it didn't have a value then we could use  {File.Categories.Direct|filter:^Where; hasvalue:This file has a Where category:This file does NOT have a Where category}.

Other formatting functions like "is" and "contains" already have this option.

No need for that.

1. hasvalue checks if the tag has data. If this is the case, the value given in hasvalue is returned. The purpose of this function is to emit a certain value if a tag is filled.

2. To emit a value when a tag is not filled, use the default function.

3. If you combine both, you can emit A when a tag is filled, and B if it is not filled.

For example:

{File.MD.XMP::exif\GPSLatitude\GPSLatitude\0|default:No GPS coordinate;hasvalue:GPS coded}

returns "No GPS coordinate" if the GPSLatitude is empty, and "GPS coded" when it is not empty.

Thanks.   I did read the help file but didn't connect default and hasvalue.  Rather I compared hasvalue to is and contains.  I will suggest a small amendment to the help file in the appropriate manner.

Ahem.  That's exactly what I meant by "the appropriate manner".  Done already.

Too late. I've already added a sentence this morning to the help after posting my answer to your request

Gosh it's hard to keep up, let alone get ahead.
