[GUI Plugin] Action Chains

For instance, I have an chain that calls up the metadata view for a book via Calibre Actions. Sometimes I do something beforehand that unselects the books in the view, but I forget and when I run this chain, I get an error about nothing being selected. Just hoping to avoid that.

You can set the following condition on the chain:

template = program: selection_count()
datatype = number
comparison = ">"
condition value = 0

Note, however, that this can lead to a lag when clicking the Action Chains menu while having a lot of items selected (hundreds of books), because the condition will take some time to be processed.

Try the chain attached. It should extract the icons to a folder called calibre-default-icons inside your home directory.

To import the zip file, open the chains dialog > right click > import chain > select zip file.

Dear you guys,

I'm totally new to this plugin. I would like to do a regex search and replace in the book content whenever it is modified. Is it possible?

Please be kind and help me if it is. (I'm no python dev to be familiar with the code)

I don't understand exactly what you want to do. But I have two things to point out:

• While Action Chains has an event manager that makes it possible to launch chains in reaction to certain events, it does not currently have an event that is triggrered by modifying book(s). I decided no to include such an event because it is not uncommon for a lot of books to modified successively very rapidly (some examples of this are the check quality and modify epubs plugins). Having chains launched in response to event that can be fired multiple times per second can wreak havoc.
  
  One solution for this would be caching the events and and firing one event for all books when calibre is idle. However, this is in the future for now.
  
  
• What you can do is include the modifying actions as a part of chain, and adding your search/replace action at the end of same chain. You can use the Editor Chains plugin to search/replace supported formats from Action Chains. It has an action that can use saved searches from the calibre editor for this.

Thank you.

I will explore the Editor Chains. Didn't know it exist.

I didn't have a chance to try it out right away, but this worked great, thanks!

selection_count was helpful too.

I really ould like to change title and author in list-view. But i cant find the action in Action Chains. Is it possible to add this function to a key? This would save me a lot of time.

[JSWolf]

Ask in the Action Chains thread and clearly explain what it is you want to do.

List view already has a shortcut for editing, you press f2 while on the cell you want to edit.

If that is not working for you, you can try making a chain with one or multiple Single Field Edit actions, where you choose the field(s) you want to edit, and set it to ask at runtime. After that you can bind the chain to whatever keyboard shortcut you want.

Version 1.17.5

• Update: update to calibre6 icon themes. Code borrowed from @JimmXinu.

Goal is to have Calibre download only metadata with a single key press.

I was able to create an action to bring the MD download dialogue up with one key press (setting a custom shortcut key), but it seems I need extra code for pressing 'm' as the next (and last) chain action.

Is there some python code I can use in that case? (please, please..)

There was a problem with the module that interfered with calibre's normal metadata download. I posted a new version. Please restart calibre and copy the new code instead.

Attached screens show, in no particular order, the steps needed to implement this.
