Bulk Rename Tags

gsd2012 · 03-18-2022, 08:40 PM

I know this maybe a topic that has come up a few times but I could not find a direct answer. Is there a way to bulk rename tags in Calibre? Maybe log that contains them all? A tool I am not familiar with? I did set a rule to Capitalize the tags but what if you have a bunch that are all lower case titles and want them to be upper case titles? Do I have to use the Tag editor to do each one?

I have started to remove all the junk ones but I have thousands that are not done right in terms of title cases. Any help would be great.

If you right click on "Tags" in the left column, there is a Tag Manager. Maybe that will help?

I have been using that but you have to do each one, one at at time. I wanted to know if you can bulk rename them? Seems like that would be a nice feature to correct all tags into Title format what all the first letters of each word being in caps. It would be nice to highlight them all and then say set to all works capitalized like a title. Some are all lower case, some are all upper case, and some are half and half.

I'd use the Tag Manager get rid of the rubbish tags by deletion

I would then do a library backup, and then use a regular expression in Bulk Edit Search and Replace to change lower case tags to Title case.

Ok not that good with reg exp so how would you do that? What would the expression look like?

Nor me, I always have to work 'em out by hit and miss - hopefully one of the re-wizards will come along soon.

If I wanted to do this then I would change all tags to title case. Any words in tags that are all in lower case would be changed. Words in tags that aren't, for example have embedded uppercase letters, wouldn't be touched. E.g.,

Code:

aAAa ::: Aaaa bbb ::: aaaaa ::: bBbb bbb => aAAa ::: Aaaa Bbb ::: Aaaaa ::: bBbb Bbb

Rules more complicated than that requires human intervention

A nuclear option is to change all tags to lower case, then in a second run change all tags to title case, then in a third pass fix the ones now broken. It is hard to imagine that this is a good idea, but heh, what do I know?

In general, regular expressions in calibre have trouble dealing with matching case because calibre tries very hard to ignore it. Search & replace can deal with case but it is hard to handle words like VoIP that are intentionally mixed-case. The difficulty is increased by the rule complexity: calibre's titlecase() function tries very hard to handle (English) punctuation and acronyms.

Ok I see what you mean there. I was just trying to make all the tags look the same. I wish there was a place like a log it puts them in and I can got and just correct them all from a txt editor and get rid of all the junk stuff. Thank you for all the help.

I'm using this thread for a slighltly different request (I hope it's OK).

I wish to rename many different tags (>1000), in one hyerarchical category, by adding an additional word to them.

E.g. Rename tags " Prize.[name of the prize].[year of the prize] " to " Prize.[name of the prize].[year of the prize].Winner " (and similarly rename tags " Lists.[name of the prize].[year of the prize] " to " Prize.[name of the prize].[year of the prize].Shortlist ")

What would be the regex expression to use?

Thanks!
