save only epub on disc using one folder file-name-error

[drMerry]

I used the function save only epub on disc using one folder.
When the select folder window was opened, the default location was my desktop.
I pressed ok directly (so no folder was mentioned in the select folder input box)

The book was copied correctly.
It was named:

g_c-exception!_single_'}'_encountered_in_format_string.epub

[drMerry (invullen)]

the used format-string in my settings is:

{author_sort}/{series:||/}{title} - {authors}

[drMerry (invullen)]

This is no help - request for a good format-string.
I think the default action should be to name the book in the same way as it is done in calibre, excluding the id.

[Charles Haley (cbhaley)]

IMO, this is not a bug. When saving a single format, only the last component of the path is used. Calibre finds that component by splitting the path on slashes. In your case, the slash in the middle of the template caused the template to be split. Because saving is done in a separate job, the only way to signal the error is to write it into the path.

@charles: It should be possible for the the template processing system to raise an exception, which would cause the saving of that file to fail. That error would then be reported to the user once the saving job has run.

[Charles Haley (cbhaley)]

It has been a given that template processing would never throw an exception. I am nervous about changing that. However...

I have changed save-to-disk to use an unsafe formatter. Any exceptions tossed during template processing will now propagate out and, one hopes, be handled correctly

Fixed in branch lp:calibre. The fix will be in the next release. calibre is usually released every Friday.

If you want, you can contact me using and I will test it in the new release.

Thanks you for the fix
