Saving To Disk Is Messing Up Filenames

ReddFour · 05-25-2016, 12:26 PM

When I select a book in Calibre and click Save to disk it is saving the book but renaming the file. For example a filename with "C++" in it will get renamed to "C__" which is annoying. I have read that this is due to Calibre removing characters that are incompatible with certain operating systems (which I think should be optional not forced) but is there a way to tell cailbre to rename it to "CPP" instead?

Sure, using a filename template in Preferences ==> Save to Disk

e.g.

Code:

{title:re(C++,CPP)}

Thanks. I tried that like this:

{series:re(C++,CPP)}/{title:re(C++,CPP)} - {authors}

But I get the following error:

calibre, version 2.54.0
ERROR: Invalid template: <p>The template {series:re(C++,CPP)}/{title:re(C++,CPP)} - {authors} is invalid:<br>multiple repeat

Dur... how mortifying.

You need to escape the plus sign. It is a regex special character.

It still doesn't do anything though. i.e.

{series:re(C\+\+,CPP)}/{title:re(C\+\+,CPP)} - {authors}

I know it's been a week or so and you probably found the answer you wanted by now (hopefully) .. but if it helps, I just copy/pasted that exact template and it saved fine. (CPP instead of C++ (or C__)).

The only thing I can think of is

Code:

{series:re([Cc][\+✝⨢＋]{2},CPP)}/{title:re([Cc][\+✝⨢＋]{2},CPP)} - {authors}

This^^

There is no good reason why that regex should fail to work as expected; there must be some additional component or issue that you overlooked.
Unless we have some way of duplicating your error, we won't know how to help you fix it...
