Please pad the file name auto-numbering, when saving multipole pages.

[Nathan Hartley]

Right now the files are saved with the following naming pattern name-#.ext . It would be helpful when working with other applications to have the files padded so they sort alphabetically in the correct order, like so name-####.ext .

Thank you.

is it good that the number of digit (4 at this point) is hardcoded.
generally i'd think using as many as needed (depending on the biggest number to be used (aka number of pages)) would be better. this would possibly be problematic when a document grows from 9 to 10 pages, however.

Please review push request with adaptive zero padding.

[Michael Nagel (nailor)]

I meant that it should be discussed if the padding should be adaptive.
it might be better (in most cases) but it might be worse (as stated above -- number of pages changes).
so i am not really sure what to do.

about the code: i do not really understand what you do.
why do have a loop instead of doing:

width = get_n_pages ().to_string().length;
number_format = "%%0%dd".printf(width)
filename = prefix + "-" + number_format.printf(i+1) + suffix
return File.new_for_uri (filename)

In fact file names are adaptive in SimpleScan. For example, a single-page document doesn't have numbering at all.

[Victor Mireyev (victor-mireyev)]

Hi Michael, you're right, loop isn't necessary in this case.

[Victor Mireyev (victor-mireyev)]

Hi Michael, I've personally stumbled upon problem with file name sorting without padding. So I'm sure it would be useful improvement of SimpleScan program.

By the way very popular and well know programs such as ABBYY FineReader and ScanTailor also provide zero padding feature, but in fixed and not adaptive variant.
