There has been a link from the start under the entry: Custom actions and events.

I posted a custom action here that addresses the filtering problem, without the need for using templates.

• The user can use the action to save current selections to a named variable (e.g. chain_selected_ids, previously_selected_ids, third_action_ids .... etc)
• The user can restore the selections from a named variable.
• The user can apply a regular calibre search that will limit the selection to a subset of one of the following:
  • Currently selected books.
  • Book ids stored in a variable
  • Books in current scope

Notes:

• Regular calibre search allows for using templates. You consult the calibre search documentation, looking for the section named: "Search using templates"
• The selection is going to be limited by the current library view including the search vls applied. To clear those, you can use the builtin "Selection Modifier". There is no need to duplicate the same functionality.
• The action is called "Subset Selector" for lack of better name. More descriptive suggestions are welcome.
• The action will not be part of the stock plugin until it fully matures and has a stable api.

Yes, sorry. Export is attached.

There are two issues I can detect:

• The following condition does not result in a consistent type of output
  
  

  program:
      if field_exists("#ong") then
          1.00
      fi

  It should be modified as follows:
  
  

  program:
      if field_exists("#ong") then
          1.00
      else
          0
      fi

  Because the condition evaluator is expecting a number even if the "if statement" evaluates to false. They way you wrote the condition, when the "#ong" column is absent, the template output is an empty string. The condition evaluator tries to convert the empty string to number and fails.
  
• If you modify the condition as described, the chain is still not going to run if either the #lector or #prox columns are absent, because unlike what you did with the #ong condition, you did not tick the checkbox "Disable action validation if conditions are not met"

I tried the chain after modifying the condition above, and after creating the #lector and #prox columns in a test library, and it runs fine (I deleted the My Tools action as I do not have it on my system).

Thank you very much! The change to number was only to try something different, and it's bad luck I checked the only one with that checkbox ticked. And yes, My Tools is a personal plugin, sorry not having removed it.

The latest version of Quality Check (1.14.4) contain a support for the Actions Chains API. This is limited only to the Fix actions because that the only one that edit book metadata (when the other are only lookup actions that don't realy match with the scope of Actions Chains).
Technically, it was added into the 1.14.3, but it never was published and deployed on Mobilread.

Also, some Fix actions of Quality Check can replace certain User Action (Bulk Sort Key and Re-calc Book Size for example).

It would also be good if Action Chains can also work with the search from Quality Check. Then you can do what you want based on the output of the search.

Just curious:

A FanFicFare-related chain opens a dialog so I can copy something, then SFE to paste it into a longtext column. Is action to insert clipboard contents directly to column?

Create a custom from_clipboard() template function, by copy/paste into the module manager:

from qt.core import QApplication
from calibre_plugins.action_chains.templates import TemplateFunction

class FromClipboard(TemplateFunction):

    name = 'from_clipboard'
    arg_count = 0

    def evaluate(self, formatter, kwargs, mi, locals):
        return QApplication.clipboard().text()

Hi!

I'm trying to get action chain to do a thing where if the title contains 'Anthology' then it'll pick a update anthology in fanficfare. But I can't get the title thing working. It only seems to recognize the full title, like not just if it contains something. How do I work that in the evaluate condition thing?

Thank you for the help!

Is there a way to use AC to open the Generate Cover (default) prompt screen at runtime?

Currently, the Single Field Edit > cover option won't let me select "Ask at Runtime." (Unless I am missing an option somewhere.) So at the moment, my options are to use my defaults or to create a new condition for each cover option and then add that to a separate chain.

Also, I have noticed that AC's version of Generate Cover doesn't allow me to load in saved settings that the main Generate Cover window has. Is it possible to add this?
