Custom folder structure

[GarfieldKlon]

Hi

I'm using Calibre 0.9.7 since two or three days. Calibre use the authors and the book title for the folder structure.

Is there a way to tell Calibre to use a custom metadata field as structure? I've added #genre and I would prefer this.

I've already read this and I'm configuring the 'save to disk'. I set genre like this --> 'IT.Programming.Java'. If I export it with {#genre}/{title}/{title} I'm ending up with a folder calld 'IT.Programming.Java' ...

But I want a single folder for each genre, a folder 'IT', and in there a folder 'Programming' and so on. Isn't this possible?

STD is for EXPORT (to reader devices)
You will really farkle your library if you write into it.

I don't want to write into the calibre folder structure, I just want to export my books somewhere else with my own defined logic.

I think this could be the solution:
sublist(val, start_index, end_index, separator)

edit:
Ok here's something ugly, but it works:
{#genre:subitems(0,1)}/{#genre:subitems(1,2)}/{#genre:subitems(2,3)}/{#genre:subitems(3,4)}/{#genre:subitems(4,5)}/{title}/{title}

I don't know how to dynamically create the folder structure.

I see a 7 folder Deep (from the base folder) structure there.
ALL Folders (paths) will be created as needed

Exactly, what's so scary about that? Can I do this more generically?

Windows Will fail on long path names

Long path names aren't the same as a deep directory structure. The directories itselves are each shorter than 20 characters.

Try the template

{#genre:re(\.,/)}

This will make a folder structure out of the genres as long as there is only one genre associated with a book.

THX! It works great. Could you please explain it to me what re does? Or give me a link, I haven't found it in the help, just examples with no explanation.

The re function applies a regular expression to the current field. The "re" function's syntax and intended effect is documented in Using functions in templates - single-function mode.

A good regular expression tutorial is here: All about using regular expressions in calibre.
