Try version attached and report whether it solves the issue.

Yes indeed, that fixes it !
Many thanks, capink

hey all, sorry for the silly question. I've tried searching here and reviewing the template page, but I'm still stuck.

All I'm trying to do is find any $title which contains a colon or a hyphen, and move the second half to a custom #subtitle field.

Right now I have the find & replace working fine - the regex I use is two-stage (I don't know how to do it in one stage with the search and replace action) where I search for .+ ?[:-] (.+) and put the first match into the #subtitle field, then do a second search for (.+) ?[:-] .+ and replace the $title field with the first match, to remove the subtitle.

I'm trying to move these two saved searches into an action chain, though, and therefore I'd like to be able to just run it on any selection in my library. With the way I have it configured, though, this causes issues on books which don't have a [:-] in the title, due to how search & replace seems to work (if no capture groups exist, \1 just matches the whole search, so the full title will be transferred into #subtitle).

Anyway, what I'm trying to do now is to use a template scope to filter the action to only run on titles which contain [:-].

The problem I'm having is that I guess I'm just dumb and I can't figure out how exactly to just use a template to limit to a subset of my current scope. There's a contains(), but that seems to just give back text. I've tried downloading and reviewing a few chains posted here that have scopes, but it doesn't make much sense to me. I guess I haven't wrapped my brain around exactly how calibre templates work.

I'm sure this can all be done in one step, the main thing I have difficulty understanding is how incoming and outgoing variables are handled, or basically the 'state' of everything that I'm acting on.

Thanks for reading!

You don't need to use templates for this. You can use Basic scope with the following search:

title:~.+:.+

Hi all,

I am pretty sure that there is a really simple way to do this if you know Python and the calibre classes. Sadly I don't
So here is what I want to do:
1. display a message after a chain is completed and user has to press ok to close the message
2. display a message after a chain is completed and user has to press ok to close the message or message closes automatically after X seconds
3. query the user with a yes / no question and call a chain depending on answer (without using a new custom field to do that)

You can do no.1 and no.3 with this custom module. To add the module, go to Action Chains > Manage Modules > add > copy/paste. After which a new custom action called "Confirm" will be added, and can be used to splash a yes/no message with a customized message.

As for no.2 you simply add another "Run Python Code" action, with the following code:

import time

def run(gui, settings, chain):
    time.sleep(5)

Replace the digit in red with how many seconds you want.

Was the option to set a predefined value to the current datetime removed for some reason? template with today() works but it's odd.



EDIT: Existing ones still work as expected.

[capink]

It is working for me in both existing and new ones. Is this happening only with date columns? Also maybe the widget is resizing properly, so make it bigger manually and see if the option were hidden.

[ownedbycats]

It was a window size issue. The widget disappears if the window height too short.

Is it possible to use chain-caller on a specific variant of a chain?

Theoretically it should be possible, but I have not tried it myself. So you have a go and tell how it went:

• In the caller chain, define the following variable using the Chain Variables action:
  

  _variant_argument = 'your_variant_argument'

• In the chain caller action, enable the option to pass variables to the called chain.

I got around to finally testing this - I don't know if it failed or if I made a mistake.

My called chain has a variant called 'tbr'

program:
    add_chain_variant('Add to Backlog','rg','', 'statistics.png');
    add_chain_variant('Add to Backlog + TBR List','tbr','','statistics.png');

so I added this variable:





The two actions marked under 'tbr' didn't run, though.

EDIT: I figured it out, I misunderstood the instructions. I was only supposed to put tbr (no quotes and not the full thing) into the template.

Before I get too far into the documentation, is it possible to create a chain that:

1) Runs Sync Now from the Reading List plugin
2) Runs the SmartEject plugin

[ownedbycats]

Probably not as expected. When I run "sync now" from an action chain it just silently fails half the time and I have to run it manually.
