[Editor Plugin] Editor Chains

[nqk]

This is a great Christmas gift for me. Thank you very much.

I have been using some simple editor chains for some time now. Some search&replace items. That works well, and saves me time (thanks). But I would like to add some actions that only work on the opf file eg remove page-map. Is this possible or not? My knowledge of editor chains is still in its infancy. And I did not see any posts that clearly indicate this possibility.

Yes, you can achieve this using filename filters. See the example below: it searches only in the OPF and removes the <tours> element.

Oh man....that is so cool. I did not know this fuctionality was there.
Thank you.

Thiago, In Post #99 you provide code to solve invaild IDs. That is something I would like to automate too, but how does this code work? I have no clue as to the steps needed to do so? I have read your post and the ones before and after, but I am still clueless. My knowledge is definitely not up to scratch. Any chance as to a step by step explanation how to do this? Would be much appreciated. Thanks in advance.

First you need to create the Module via Manage Modules > Create > Replace the existing text by this:

Spoiler:

from qt.core import (Qt, QApplication)

from calibre.ebooks.oeb.polish.check import parsing
from calibre.ebooks.oeb.polish.check.main import fix_errors

from calibre_plugins.editor_chains.actions.base import EditorAction

class ReplaceIDs(EditorAction):

    name = 'Replace IDs'
    headless = True

    def run(self, chain, settings, *args, **kwargs):
        container = chain.current_container
        QApplication.setOverrideCursor(Qt.WaitCursor)
        QApplication.processEvents()
        errors = parsing.check_ids(container)
        changed = fix_errors(container, errors)
        QApplication.restoreOverrideCursor()

Then, you need to create the chain, via Add/Modify Chains > Plus sign (+) > Choose a name > Gear icon (Settings) > You can choose an icon or not > Plus sign (+) > Select the new line > Double click in the Action field > User actions > Replace IDs > Ok.

Now, the new action will appear as option in the main menu. You can also use it as part of more complex chain, like the one you asked about before, doing search and replace.
