What if I wanted to count the words of the title?

Apart from us wondering what you are up to?

Try:

program:
count($$title, ' ');

First I thought of title, but now I'm going to use it with author.
The authors column has three possibilities.

The first is that you only have a last name, like Aristotle or Anonymous, for example.
In this case I add a comma and a hyphen at the end of the name.
Aristotle,-

The second consists of a first name and a last name. If I jointly select all the authors of this type, I can transform them jointly, which is what I want.
I can transform all these authors directly into APE, NOM through the PlugIn QualityCheck

The third option would imply either two names and a surname, which would select and transform them in the same way, or one or two names and two surnames, in which case I would change them manually one by one, managing Authors, as before.

As you can see, I am only looking for a way to simplify the process of incorporating the periodic updates of the •LIBRARY

—————
With the column I'm looking to implement, I'd get a 1 for the second case. Then I would sort it, and select all the ones that had 1.

I hope I have explained myself well

Question: How would I check whether the values of identifier: and identifier2: (in this case, mobi-asin: and amazon: ) are identical?

Use the select() function. Example:

program:
	select($identifiers, 'x') == select($identifiers, 'z')

Question:

program:
	ids = $identifiers;
	mobi = select(ids, 'mobi-asin');
	amazon = select(ids, 'amazon');

	if 
		mobi && !amazon
	then 
		n = re(mobi, '(.*)', '\1');
		ids = list_union(ids, strcat('amazon:', n), ',')
	else
		ids
	fi;


	if 
		mobi == amazon
	then
		ids = list_difference(ids, strcat('mobi-asin:', mobi), ',')
	else
		ids
	fi

I have two books. Book #1 has only the mobi-asin identifier, while Book #2 has identical mobi-asin and amazon ids.

The results are this:



Aside from either separating the two parts into separate templates or running it twice, is there any way to tell it "do part A (copy mobi-asin to amazon), and then also do part B (remove mobi-asin)"?

EDIT: See my post in the while loop thread.

I don't understand the question. As you have it, both clauses will be executed. What do you want that is different from that?

Aside: what is the "n = re(mobi, '(.*)', '\1');" for? That (almost) copies mobo to n. Except there will be problems with the .*, which can copy the empty string. Why not just use 'mobi' in the list_union()?

[ownedbycats]

Lines 6-13: If there's no amazon identifier, copy the contents of mobi-asin to it.

Lines 16-22: If mobi-asin and amazon are identical, remove mobi-asin.

As it currently is, if there's only mobi-asin, it will copy it to amazon but then not remove it afterwards, and I need to run it a second time.

I think one of the ids in the second section is checking the original state of the column and not the updated one.

I figured it out! I added two lines between the clauses, and it updated the variables. I suppose this might be a case where using variables as a typing shortcut wasn't a good idea.

program:
	ids = $identifiers;
	mobi = select(ids, 'mobi-asin');
	amazon = select(ids, 'amazon');

	if 
		mobi && !amazon
	then 
		n = re(mobi, '(.*)', '\1');
		ids = list_union(ids, strcat('amazon:', n), ',')
	else
		ids
	fi;

	mobi = select(ids, 'mobi-asin');
	amazon = select(ids, 'amazon');

	if 
		mobi == amazon
	then
		ids = list_difference(ids, strcat('mobi-asin:', mobi), ',')
	else
		ids
	fi

	then
		ids = list_difference(ids, strcat('mobi-asin:', mobi), ',')
	else
		ids
	fi

Instead of redoing the select you could add after the list_union() line

amazon = mobi

Question: When exactly does a stored template re-calc?

Example: Suppose I have a stored template that I use in an action chain to modify a column. Does it only calculate when I run the chain?

I assume "calculate" means "run". It runs when it is used no matter the context. In an action chains context it will be the chain template that calls the stored template.

Is there a way to change the template based on the format of the book being sent?"

I send both .epub and .cbz to my device and prefer different naming schemes for them.

With .epub, I like
books/{author_sort}/{series}/{title}

But with .cbz, I want
books/{author_sort}/{series}/{title}
(being comics, each chapter/volume is already named {series}{series_index})

Currently, I either have to manually edit the template each time I switch formats (which also requires restarting Calibre and remounting the folder), or I have to switch how the device is mounted (Connect to Folder for .cbz and Wireless Connection for .epub)

There's got to be an easier way though, right?

[ownedbycats]

I may be wrong on this, I don't believe variations can be done with a basic template.

I have a similar case, and what I did was create a composite column and use a GPM template. Try working off this -- I'm a bit foggy on how to do the 'stuff here' though :

program:

	if 
		'cbz' in approximate_formats() 
	then
		'(some stuff here)'

	else	
		'(other stuff here)'

	fi

Then just put {#yourcompositecolumn} into the save template field.

For reference, here's my templates:

program:

# Returns 'Fanfiction/Fandom' for fanfics
	if $$#fanficcat then
		list_re($tags, ',', '^Fanfiction.(.*)$', 'Fanfiction/\1')

# Returns 'Kobo' for Kobo store books (in the rare case I need to sideload one)
	elif '\[Kobo Store\]' in $#kobostatus then 
		'Kobo Store' 

# Returns 'PDF' if PDF is only format
	elif $formats == 'PDF' then
		'PDF'

# Returns 'Loans' for Loans
	elif 'Loans' in $#vls then
		'Loans'

# Returns topmost tag for all other books
	else
		re(sublist($tags, 0, 1, ','), '^(.*?)($|\..*$)', '\1')

	fi

{#kobopath}/{author_sort:sublist(0,1,&)}/{title} - {authors}
