I defined a template function called current_column (see the code at the end of this post) that gets the selected column name, if @chaley has no interest in adding something similar to calibre, I will add it to the next version of Action Chains.

For now, you can define it as a custom template function in the module editor (see instructions below). After defining this function in the module editor, you can call it from your template:

program:
    col_name = current_column()

I don't use the Kobo Utilities plugin, so I am not sure what you are talking about here. Maybe someone else can help with this.

I am not sure what you want exactly. If you are talking about friendly names for your devices, there is a function defined below (friendly_connected_device_name) that helps you map the names. First, you need to edit the dictionary (highlighted in blue).

After defining this function in the module editor, you can call it from your template:

program:
    device = friendly_connected_device_name('main')

Thanks.

To add the code below that contains both functions:
Action Chains > Manage Modules > Create Module > Copy/Paste the code below

import traceback
from calibre_plugins.action_chains.templates import TemplateFunction
from calibre.utils.formatter_functions import BuiltinConnectedDeviceName

class CurrentColumn(TemplateFunction):

    name = 'current_column'
    arg_count = 0

    def evaluate(self, formatter, kwargs, mi, locals):
        from calibre.gui2.ui import get_gui
        lv = get_gui().library_view
        col = lv.column_map[lv.currentIndex().column()]
        return col

class FriendlyConnctedDeviceName(TemplateFunction):

    name = 'friendly_connected_device_name'
    arg_count = 1

    def evaluate(self, formatter, kwargs, mi, locals, storage_location):
        from calibre.utils.formatter_functions import BuiltinConnectedDeviceName

        friendly_names = {
            'name_1': 'friendly_name_1',
            'name_2': 'friendly_name_2',
            'name_3': 'friendly_name_3'
        }

        try:
            name = BuiltinConnectedDeviceName.evaluate(self, formatter, kwargs, mi, locals, storage_location)
            return friendly_names.get(name, name)
        except:
            traceback.print_exc()
            raise

Edit: Defining the function as pointed out by chaley in the next post, gives you the advantage of being able to use it outside Action Chains as well.
