custom export

[iomari]

I currently use the following template for exporting my books to separate folders based on filetype:

{#supercat}/{tags}/{authors}/{title} - {authors}

It works fine for me. I chose which type to export and it neatly places chosen type in well organized folders. However I have to run the export for each book type that I have to achieve what I want. Is there a way to structure the template to place the various types into their respective folders? When I do each one manually I end up with different top folders for each type by choosing the parent when I save. I want to automate this whole process.
btw, #supercat is a custom tag. :-)

If you have one format per book, then you can use
{formats}/{#supercat}/{tags}/{authors}/{title} - {authors}

If you have multiple formats per book, then the above probably won't do what you want, as you will end up with folders named "EPUB, MOBI, PRC" or some such. I can't think of a way around this problem. This isn't any field available containing the current format.

Yes I have multiple formats per book and the first thing I tried was using {formats} but as you stated it gave me folders like you described.

In the left pane, the "formats" field shows the total for each format separately. How can I access the function that breaks down each format like that?

What exactly are you trying to do?

If you are trying to find a template language function that returns the number of (for example) epubs in the library, there isn't one. Template functions operate on individual books, not on a database.

If you are trying to find the number of formats for a specific book, then use the count function, as in {:'count(field('formats'), ',')'}.

I'm trying to export my books with the book formats as the top folder. my current template is:
{#supercat}/{tags}/{authors}/{title} - {authors}

what I want is something like:
{formats}/{#supercat}/{tags}/{authors}/{title} - {authors}

except I want a case where if there are multiple formats per book that a copy of each format gets placed in separate folders. Not where I would end up with folders like:

"EPUB, MOBI, TXT".

In a case like this, I want each book to get routed to:

EPUB/{#supercat}/{tags}/{authors}/{title} - {authors}
MOBI/{#supercat}/{tags}/{authors}/{title} - {authors}
TXT/{#supercat}/{tags}/{authors}/{title} - {authors}

Hope this is clear. I know I can get my hands dirty and write a custom script but I don't want to do so if there is an existing easier way of doing it.

As I said above, there is no way in the template language to know the current format being saved. In fact, even the part of calibre code that generates pathnames does not have access to the extension (format). Because of this, there is no way in the template language to route a particular format to a particular folder.

@Iomari
It is not as efficient, but you can get your output.

First: Search (or use the Tag Browser: Formats: ) to show only books that have the format you want.
Set your save template first folder (a literal) to the format name.

EPUB/{#supercat}/{tags}/{authors}/{title} - {authors}

Your example is a valid template.
You can use literals mixed in with field names.

He said in the first post that he doesn't want to do that.

Forgot that was said (it was that far back in the thread).

Looks like I'm going to have to write a custom command line script to do this. I don't have a problem with that but if there was some built in way of doing it I would rather not spend the time writing what is already available.
