That doesn't stop Xwang from writing one for his own use, though.
First, Xwang, have you proven that changing the author/title to uppercase like that solves your problem? You tried it manually with a smaller set of books, that is?
Assuming so, I suggest a UI plugin that searches for titles/authors with lower case and updates the metadata on command.
One place you could start is with the Extract ISBN plugin. It's the simplest plugin I know of that modifies metadata. You don't need the whole background processing part, but the technique used to update isbn can probably be adapted to update title/authors instead.
Another possible way to do it is this:
Code:
db = self.gui.current_db
bookids = db.search_getting_ids('title:"~[a-z]" or author:"~[a-z]"', None)
for bookid in bookids:
mi = db.get_metadata(bookid,index_is_id=True)
mi.title = mi.title.upper()
auths=[]
for auth in mi.authors:
auths.append(auth.upper())
mi.authors = auths
db.set_metadata(bookid,mi)
db.refresh_ids(bookids)
I haven't tested it, so I doubt it would work exactly as is, but it's a starting point.
