I have two input values: TAG_VALUE and FIELD_NAME, and two complementary use cases:
-
For all tiddlers in a wiki that have a TAG_VALUE tag, add a field FIELD_NAME and set its value to TAG_VALUE, but only if field FIELD_NAME doesn’t exist, or exists, but has an empty value (because I don’t want to accidentally overwrite existing data)
-
The opposite of 1. - for all tiddlers that have a field FIELD_NAME with a non-empty FIELD_VALUE, create a FIELD_VALUE tag.
Is this possible to be done with any existing plugin? My first thought was Tiddler Commander, but it seems to separate management of tags and fields into different tabs.
I’d like this for being able to convert between vanilla ToC which uses tags, and tocP style ToC, which uses parent field to store relationships between tiddlers
