Prevent spellchecker from opening every file

Karellen · 12-15-2021, 10:38 PM

I have noticed a weird behaviour when running the spell-checker in the Calibre Editor.

I use F8 to jump between words identified by the spell-checker as being incorrect. I like to do this a page at a time, on the page I am currently working on.

The problem is that when you (unknowingly) arrive at the last word to be checked and press F8 again, you end up on the next xhtml page. That in itself is not a problem, but what happens is that every single page in the epub file is opened- xhtml, ncx, opf. I then have to close every page down.

Is there anyway to prevent this behaviour. I am happy that it opens the next page, but I don't expect that it opens every single page in the epub file.

Thanks

Fantastic. Looking forward to the next release

Thank you @kovidgoyal

Confirming this fix solves the problem.

Using F8 works as expected when reaching the end of the page. It opens the next page only.

Thanks

Weird. This issue has come up again, but seems to only happen with a particular search string.

If I search for \b(.*?)\b, every page in the ebook opens in the editor.
(yep, its a bit of a nonsense regex)

That's because the regex matches the empty string.

Thanks @kovidgoyal
But why should that open every file in the epub?

Because matching an empty string is indistinguishable from not matching, one piece of code sees there is amatch and opens the file, another sees theres no match because its empty and searches the next file and so on.
