MobileRead Forums - View Single Post - Template: Extracting a number from a string

ownedbycats · 06-24-2021, 05:46 PM

I have two columns, text #kobobookmark and integer #chaptercount.

I'd like to create a new column to keep track of read chapters in a fanfic, e.g. 5/25.

I thought the best way to do that is a GPM template that
a) checks a book is a fanfic, is currently being read, and has something in #kobobookmark to count,
b) extract the number of read chapters from #kobobookmark,
c) display that number next to #chaptercount.

I managed to get the first part working already:

Code:

program:
	if 
			$#fanficcat 
		&& 
			$#currentlyreading 
		&& 
			$#kobobookmark
	then
		$#chaptercount
	fi

Unfortunately the implementation of b and c I'm a bit stuck on. The bookmarks are always in a string similar to this:

OEBPS/file0003.xhtml#kobo.1.1

The "0003.xhtml" means that it's currently on chapter 3. What would be the best way to get the number and display it as '3/{#chaptercount} chapters read'?
