I have an editor which uses Kate syntax files.
Last update file I found is https://kate-editor.org/syntax/update-5.256.xml
How to determine the latest number or list of all these files ?
Are not linked from https://kate-editor.org/syntax/index.html.
I can download the index and parse it but the index has no version numbers.
Latest version update can't be found in Kate nor in the KDE
syntax-highlighting repositories.
