Using filenames to number chapters?

Phssthpok · 10-18-2023, 07:26 AM

I have a bunch of files called chapter1.html, chapter2.html, ... where the chapters themselves have not been numbered.

I want to take the file name and insert it into the text of the file. Is there an easy way to do this?

Is the reason for that because you don't want to manually add the chapter numbers as there may be a lot of chapters?

Making a code Snippet , would speed things up. You just add the missing piece.

Depending on where you want to insert the text, you can utilize the replace function mode with the function below

Code:

import regex

def replace(match, number, file_name, metadata, dictionaries, data, functions, *args, **kwargs):
    if not file_name.lower().startswith('chapter'):
        return match.group()
    name = regex.sub(r'(.+?)(\d+)\.x?html?', r'\1 \2', file_name).title()
    header = f'<h1>{name}</h1>'
    return regex.sub('(<body[^>]*>)', r'\1' + '\n' + header, match.group(), regex.MULTILINE)

The search string should be: .+
Then press replace all.

This will insert the chapter heading as a h1 header at the very top (just below <body>)

Ah, excellent, many thanks!
