Export to disk, using functions

[ZaMotH]

Hi all,

I export all my ebooks to a file system, structed by folders. I have 2 ruleset for exporting :
- Export by name :

{authors:.1}/{authors}{series:| - |/{series_index:0>2s}} - {title}

- Export by series (when multiple authors work on same series) :

-Series-/{series}/{series_index:0>2s} - {title} \[{authors}\]

To seperate both, I added a tag : "By series"

Now, I would like to do all of this at one time, and I tried to look over functions, but somehow, when the query gets complicated, the export crashes :
This works

{tags:contains(By_series,-Series-/,{authors:.1}/)}{title}

In bold, the added statement which makes it not not work anymore

{tags:contains(By_series,-Series-/,{authors:.1}/{title}/)}{title}

Throwing the following error

calibre, version 0.9.1
ATTENTION : Impossible d’enregistrer certains livres: Impossible d’enregistrer certains livres, Cliquer le bouton afficher les détails pour voir lesquels.

Le Gardien de la Pierre
	Traceback (most recent call last):

	ValueError: A échoué à calculer le chemin pour enregistrer sur le disque. Modèle : {tags:contains(Export_Par_Serie,-Series-/,{authors:.1}/{title}/)}{title}
	Erreur : Incorrect number of arguments for function contains

... And 1 block like this for every ebook ...

Of course, what I would have liked to be able to do was (added return for better read) :

{tags:contains(By_series,
-Series-/{series}/{series_index:0>2s} - {title} \[{authors}\],
{authors:.1}/{authors}{series:| - |/{series_index:0>2s}} - {title})

Maybe I should not use tags ? Maybe I should use another function ? If any one could advise me, I would greatly thanks him/her.

Best regards,
Thomas

You are using a sub-template as a function argument, something that frequently breaks things. That is why the documentation for single function mode says you are not supposed to do that.

You should use general program mode. In GPM, your last template would be something close to:

program: 
	contains(field('tags'), 'By_series', 
		template('-Series-/{series}/{series_index:0>2s} - {title} [{authors}]'),
		template('{authors:.1}/{authors}{series:| - |/}{series_index:0>2s} - {title}'))

I changed the second template so that it does not use a subtemplate for series_index.

Hi,

Made a small mistake by willing to remove the "program:" ident, but after some 1 minute reading, I understood this was needed.

So now my exports works perfectly. I also wanted to try some advanced features, but after some reading, since I never coded in anything else than vbs and powershell, I left my export as is. If I have 30 minutes to spend, I will try to look deeper at it and increase my regex skills.

Regards
Thomas
