Cannot replicate. Export the chain and post it here.

Windows 11 / calibre 6.20 / Action Chains 1.18.7

I have the same problem as Philantrop.
I can't add a calibre action.

Here is the json file from export.

Spoiler:

Thanks

I still cannot replicate the problem even when switching language to French. The strange thing is that the calibre actions you uploaded does not run the function that raises the error, because it is a top level action (Extract ISBN). Are you sure you uploaded the right chain?

Anyway, here is modified version of the plugin that has print some debug statements. Please run this modified version in debug mode, and post your debug log.

Bertrand · 06-13-2023, 07:17 AM

Thank you.

Here is the log file (not sure if it is what you want) and a new export of the action chain, just in case.

To be clear, I get the error as soon as I click the icon settings
- If I want to modify a calibre action (for example, Extract ISBN in the screenshot)
- If I want to add a calibre action

(I also tried on a portable version of calibre, and I get the same thing)

capink · 06-13-2023, 07:44 AM

From what I can see from the log the problem is one of the multiple SortAction is returning an int value of 0 instead of returning a text value (when calling QAction.text() method). I don't why this is happening and why it is not replicated on my system.

Anyway try this new version, see whether it helps with the problem.

Bertrand · 06-13-2023, 08:50 AM

It works.
Thanks a lot !

I'm late to the party because I never got notified of your reply, sorry. I'm all the more happy to also report things working fine now. Thank you very much for the fix and, of course, this fabulous plugin!

Comfy.n · 07-05-2023, 01:07 AM

Hi, do we have a chain for Prince PDF plugin? I could only set up the first step, that runs the existing Calibre Action and brings up the plugin dialog. Then we would need some script to send alt+P, then maybe wait a second, then send alt + V.

Venia Legendi · 07-05-2023, 04:38 AM

Trying to use an old chain (which has worked AFAIK), I get "EXCEPTION: Formatter: Unknown function set_persistent_vars"?

Problem in front of the screen?

Update: Add persistent storage for templates. Can be accessed using these new template functions: persistent_vars(), set_persistent_vars(), list_persistent_vars(), delete_persistent_vars(), list_persistent_namespaces(), delete_persistent_namespaces()

Persistent vars functions were removed after the introduction of python templates, which provides better solution if you know python.

I thought no one used them. But if you want to get them back, copy the code below into your module editor:

No. It it is not working through Calibre Actions, the only way is for someone to write a custom action that calls the plugin's code directly.

Thank you, code works, I'll switch then to python templates.

Question: Is there a method to add a file to the extra data folder similar to SFE on 'formats'?

Context: I have a chain that copies the cover path to clipboard then follows it with the 'add data file' Calibre action where I paste it in. It's a little clunky though.

You can do this with a python template. It would probably be better as an Action Chains python action but I didn't feel like doing that.

Code:

python:
def evaluate(book, context):
	import os
	from shutil import copy
	from calibre.db.constants import DATA_DIR_NAME

	db = context.db
	cache = db.new_api
	# Get the normalized library path
	library_path = cache.backend.library_path
	
    # Construct the full path to the book folder
	path = os.path.join(library_path, cache.field_for('path', book.id).replace('/', os.sep))

I don't why this is happening and why it is not replicated on my system. Anyway try this new version, see whether it helps with the problem. Last edited by capink; 06-14-2023 at 01:42 PM.

I could only set up the first step, that runs the existing Calibre Action and brings up the plugin dialog. Then we would need some script to send alt+P, then maybe wait a second, then send alt + V.

ownedbycats Custom User Title Posts: 11,347 Karma: 79528341 Join Date: Oct 2018 Location: Canada Device: Kobo Libra H2O, formerly Aura HD	Question: Is there a method to add a file to the extra data folder similar to SFE on 'formats'? Context: I have a chain that copies the cover path to clipboard then follows it with the 'add data file' Calibre action where I paste it in. It's a little clunky though.
