Save to disk (file names)

[HDvision]

Hello,

i tried everything
but when it comes to save my files to disk, following will happen:

i use: {author_sort}/{series} - {series_index} - {title} - {authors} - {isbn}

because i want to have:

SERIE - NO. - BOOK NAME - AUTHOR - ISBN

all fine WHEN the book has a SERIE

BUT IF NOT

the file name is like this:

- - SERIE - NO- BOOK NAME - AUTHOR - ISBN

i dont want those two " - - " at the beginning.

how can i remove them?

thanks a lot

Try the following.

{author_sort}/{series:||-}{series_index:re(^(\d)(\.|$),0\1\2)||-}{title}-{authors}-{isbn}

@dwanthny: why use 're' to add the leading zero instead of using something like 05.2f as the number format string? Are you ensuring that ".00" (or something like it) isn't added to integer series numbers?

I have to plead ignorant. I copied this from this forum ages ago and in the rare times I use it I seems to produce what I desire.

hello dwanthny, thank you so much, i have no glue WHY it WORKS, but it does

i changed it a little to get spaces:

{author_sort}/{series:|| -} {series_index:re(^(\d)(\.|$),0\1\2)|| -} {title} - {authors} - {isbn}




@chaley
u mean i can shorten the template?
i mean it does already what i want it to do
so what would be the advantage from changing the thing with 're'?
dont even know what it means

The 're' adds a leading zero to series indices that are 1 digit long. For example, an index of '5' will be changed to '05', while an index of '15' will be left alone. If you don't want this behavior, then you can use

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

My question related to how the leading zero was being added. A different solution is to use a format specification that ensures that the series indices have a fixed look. For example,

{author_sort}/{series:|| -} {series_index:05.2f|| -} {title} - {authors} - {isbn}

will produce the following output for the given series indices:
1 -> 01.00
1.4 -> 01.40
10 -> 10.00
14.43 -> 14.43

Also note that your template will put an extra space after the slash if there is no series or series index, and will have an extra trailing - if there is no ISBN. You probably want to use

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

As for why it works: if a template element is not empty, then the text after the first | is inserted before the value and the text after the second | is appended after the value. If the template element is empty, then no text is inserted or appended. Thus if a book has an ISBN, a " - " is inserted before it. If the book has no ISBN, then nothing is inserted.
