Title-case text (ignore tags) Not Necessarily Working

enuddleyarbl · 01-26-2023, 02:05 PM

Another weird one. Sometimes, the Calibre Editor's Regex-Function mode of "Title-case text (ignore tags)" doesn't completely change the case of the text. I haven't been able to find a reason why. For instance, just now, I had it look for:

Code:

<h2>(.+?)</h2>

and it correctly found and highlighted:

Code:

<h2>Introduction: CARLA LEMARCHANT</h2>

When I told it to do the replacement, nothing changed. I backed the cursor off a bit, tried again, and got the same result. So, I switched the mode to "Lower-case text (ignore tags)", hit the Find and the Replace buttons and it correctly found and lower-cased the thing. I changed it back to Title-case and it now worked.

Then, I manually changed it back to its original, and Title-case didn't work again. The Lower-case function worked and then Title-case on that also worked. If I use the "Upper-case text (ignore tags)" mode and back to Title-case, that also works.

EDIT: I should have been more specific about "didn't work." The stuff before the colon (":") converts fine (even with more than one word). The stuff after the colon is where the problem always seems to happen.

calibre's title case function won't change a string that contains uppercase letters. Reason: acronyms. The workaround if you really want the case changes is the one you found: convert to lower case first.

Yes, I have noticed that also. They have problems with mixed cases. So either convert to all upper or all lower case, then use the Title case or Capitalise text

Also Title case needs manually reviewed anyway as there are at least two sets of rules.

Best to convert all headings to lower case and then convert headings one at a time to title case.

Thanks. I never would have thought of acronyms. That makes sense.
