S/R Function Title-Case

phossler · 02-01-2015, 09:12 AM

I had some 'unexpected' results trying to re-format a lot of Hx titles into TitleCase.

Ending up making just a small test doc to investigate further

It seems as if the TitleCase function stops if the first word is already in mixed case so the first H1 is found but not replaced. The rest are fine

Code:

<body>
<h1> Chapter 1 AAAAAAAAAAAAAAA BBBBBBBBBBBB CCCCCCCCCCCCCC</h1>
<h1>CHAPTER 1 AAAAAAAAAAAAAAA BBBBBBBBBBBB CCCCCCCCCCCCCC</h1>
<h1>chapter 1 aaaaaaaaaaaaa bbbbbbbbbbbbbb cccccccccccccccc</h1>
<h1>AAAAAAAAAAAAAAA BBBBBBBBBBBB CCCCCCCCCCCCCCCCCCCCCC</h1>
</body>

The workaround I've found it to do the S/R with the built-in UPPERCASE function first, and then the TitleCase

Is there a way to 'include the call' to the UPPECASE function as part of the TitleCase function?

I got far enough to see the function (or at least I think it was) but couldn't figure out to to do it myself

Code:

from calibre.utils.titlecase import titlecase
from calibre.ebooks.oeb.polish.utils import apply_func_to_html_text

def replace(match, number, file_name, metadata, dictionaries, data, functions, *args, **kwargs):
    '''Title-case matched text, ignoring the text inside tag definitions.'''
    return apply_func_to_html_text(match, titlecase)

Thanks

Works fine for me.

thanks for checking, but the first of the 4 <h1> still ends up like

<h1> Chapter 1 AAAAAAAAAAAAAAA BBBBBBBBBBBB CCCCCCCCCCCCCC</h1>

If you could verify my Saved Search in the screen shot is the same as yours please?

Now I see the problem.

Titlecasing ignores words that have capitals in the middle of the word (unless the whole thing is uppercased). Try titlecasing "ChaPter".

See:

src/calibre/utils/titlecase.py line 71

Code:

        if INLINE_PERIOD.search(word) or UC_ELSEWHERE.match(word):
            line.append(word)
            continue

I originally took you at your word and tried to replace "Some text."

Case changing (when mixed) has been problematic for me from way back in the DOS days.

I always Lowered, then set the desired case

The workaround that I came up with is the UPPERCASE first and then TitleCase

That's why I was wondering about modifying the title case RegExFunction and just doing a upper case first; do it in one step

Try:

Func: "Upper-case text then Title-case it"

Code:

from calibre.utils.icu import upper
from calibre.utils.titlecase import titlecase
from calibre.ebooks.oeb.polish.utils import apply_func_to_match_groups

def replace(match, number, file_name, metadata, dictionaries, data, functions, *args, **kwargs):
    '''Title-case matched text. If the regular expression contains groups,
    only the text in the groups will be changed, otherwise the entire text is
    changed.'''
    text = apply_func_to_match_groups(match, upper)
    
    '''Now return it titlecased.'''
    return titlecase(text)
