Title Case not working on "the" "a" "in" etc

[mike the leg]

Does anyonne else have the problem that
Edit metadata in bulk -> apply function after replace -> Title Case
does not put a capital on various works like "in" "the" "a" etc

For example
"a witch in the time of the lords"
should become
"A Witch In The Time Of The Lords"
but actual becomes
"a Witch in the Time of the Lords"

Somewhere in Calibre there must be a list of words that are not to be give a capital letter.
Anyone know where and can they be remove?

RU sure it doesn't become "A Witch in the Time of the Lords"

Which conforms to the major Style Guides see Title case - Wikipedia

Example: Killers of the Flower Moon (2023) - IMDb

Normally a, is, the, in, of and similar are not capitalised unless at the start. That's what Title Case means. There are edge cases that vary between Style Guides (and languages vary). But certainly absolutely every word Capitalised is not Title Case in English.

When you change the case, choose Capitalize. It's the wrong thing to do (says my inner librarian), but you do you.

Are you sure about that.

On a vanilla calibre 6.29 install on Windows 10; Capitalise case changes "a witch in the time of the lords" to "A witch in the time of the lords", which some tools refer to as Sentence case.

I agree. Calibre's Capitalise is simply "sentence case", i.e. capitalise first letter of title.

One can do what I think the OP wants, all words capitalized, using template mode in search & replace. (Personally I think capitalizing every word is wrong, but the OP is in charge of the OP's library.)

If the titles don't contain non-alphabetic characters other than space then this GPM template does the job.

program:
	new_title = list_re_group($title, ' ', '.', '(.*)', 'program: capitalize($)')

With this template, "a witch in the time of the lords" becomes "A Witch In The Time Of The Lords".

If the titles do contain non-alphabetic characters such as colons and you want strings like foo:bar to become Foo:Bar then this python template gets close.

python:
def evaluate(book, context):
	import re
	nt = []
	for w in re.split(r'([() :-]+)', book.get('title')):
		nt.append(w.capitalize())
	return ''.join(nt)

You must list the characters on line 5 that can precede words to be capitalized. This example uses r'([() :-]+)', parens, space, colon, dash. The problem children are quotes. Sometimes one wants the capitalization after the quote (quoted words in titles, as in "What Does "Foobar" Mean") and sometimes not (possessives, as in "John's Great Escape").

The first template probably gets most of the way there. I wouldn't try to get too fancy, instead correcting any "mistakes" by hand.

The search/replace looks like this, with the desired template in the template box.

OK Chaley, thankyou, that looks like it should do what I want.
iIt is a bit beyond my programming capabilities so I will copy some books into a small library and give it a try.
