saving book to disk remove empty sting

[reup]

hi all,

I usually save my books to disk before copying them to my devices (I do not manage the devices with calibre but manually)
this below is the config I use to rename the files

{author} - {series} - {series_index} - {title}

perfect when I have a series like
Jack Campbell - Lost Fleet, The - 1 - Dauntless.epub
Jack Campbell - Lost Fleet, The - 2 - Fearless.epub

but a bit of a problem when the file is a single file like
Thomas A. Mays - - - Sword Into Darkness, A.epub

any way to remove the - - - ?

From the tutorial (open the template editor and use the Tutorial link at the bottom)

For example, assume you want to use the template:

{series} - {series_index} - {title}

If the book has no series, the answer will be - - title. Many people would rather the result be simply title, without the hyphens. To do this, use the extended syntax {field:|prefix_text|suffix_text}. When you use this syntax, if field has the value SERIES then the result will be prefix_textSERIESsuffix_text. If field has no value, then the result will be the empty string (nothing); the prefix and suffix are ignored. The prefix and suffix can contain blanks. Do not use subtemplates (`{ … }`) or functions (see below) as the prefix or the suffix.

Using this syntax, we can solve the above series problem with the template:

{series}{series_index:| - | - }{title}

The hyphens will be included only if the book has a series index, which it will have only if it has a series.
