F/R Question

[Pam E.]

They are in a cookbook epub file. :/ See a lot of them in cookbooks. I like to import recipes into my recipe management program, but I need to 'fix' all of those fractions first. This was a huge help! Thanks again.

They are a part of Unicode:

I personally avoid the use of "vulgar fractions" because what happens when you are dealing with fractions that don't have proper unicode versions? For example, 3/10.

Then you get an inconsistent look between the vulgar fractions + the non-vulgar versions.

Also, especially when dealing with some of these less common vulgar fractions, the reading devices might not have those as a part of their fonts. Sure, they will probably have ½, ¼, but the fonts most likely will not have things like ⅝ and ⅞.

I personally would go with consistency and readability over looks.

Side Note: This also reminds me about the usages of superscript/subscript in ebooks. Sure, it may "look nicer", but it makes it tougher to read for people with poorer eyesight. I personally fall into the camp that tries to avoid smaller text. (Superscript footnotes, vulgar fractions, ...).

We had a nice long chat on superscript footnotes/text back in this thread (I started it around Post #23):

Yeah, I would probably just do this as normal search/replaces, and if you are dealing with a lot of cookbooks with the same fractions, I would just create a set of Saved Searches in Sigil.

With Calibre editor,
1- Search all.
2- Use Regex-Function with:
return match.group().replace ('½','1/2').replace ('⅓','1/3').replace ('¼','1/4') ..... etc.

Thanks
This is using the very recent Edit feature ( which I have not come up to speed with).
So it can be done

Exactly! I get tired of dealing with ebooks that use them.

Excellent!!! I will give this a try. Thanks so much!

Ok, I created a new function:

def replace(match, number, file_name, metadata, dictionaries, data, functions, *args, **kwargs):
    return match.group().replace('½','1/2').replace('⅓','1/3').replace('¼','1/4')

^^Did I create the function correctly?^^

What do I use for the Find field so I can test out my new function?
