I saved this PTM template in Preferences > Template Functions:
The globals dict was of course empty since it gets filled at runtime, so an error message about the key, 'val', missing was spurious. I still was able to save & apply the PTM template.
I then ran the above PTM template in a plugin's Job using this code:
The debug log for the above Job shows:
I went back into where I saved this PTM template in Preferences > Template Functions to work on the same PTM template, but the GUI raised the error shown below, and would not let me back into Preferences > Template Functions to work on the PTM template to fix the error (Catch-22):
Since I could not use Preferences > Template Functions any more, at all, I went into metadata.db, table Preferences, key 'user_template_functions', and carved out the entry for my PTM template from the JSON:
I then ran Calibre, and could finally enter into Preferences > Template Functions since the PTM template in question no longer existed.
----------------------------------------------------------------------------------------------
Question: Can the PTM template cache get poisoned when the PTM template is run "in batch" via a Job? If so, is there a way to clear it so the template_dialog for Preferences > Template Functions can always be successfully executed?
Question: How do I create a PTM template using a dict with keys that only exist at runtime?
Question: Is this syntax supported: text = context.globals['val'] ? If not, what is the proper way to accomplish passing a single string value to a PTM template at runtime?
Thank you.
Happy/Merry Christmas.
