JavaScript template support in url_path actions

[userdema]

Hey! First of all, love the work you're doing with Bubble Card, it's really the cornerstone of my whole dashboard setup.

I wanted to raise a feature request that I think would be super useful: support for JavaScript templates in url_path, similar to how button-card handles it with the [[[...]]] syntax.

The use case is pretty common — for example, I have a card tracking a family member's location and I'd love to open Google Maps at their current coordinates with a tap/hold action. Right now the only way to do this dynamically is through browser_mod, but many users (myself included) prefer to avoid adding extra integrations just for this.

Button-card solves it elegantly: it checks if url_path starts with [[[, evaluates it as JS with hass in context, and uses the result as the URL. Something like:

hold_action:
  action: url
  url_path: >
    [[[return 'https://maps.google.com/?q=' +
    hass.states['person.maurizio'].attributes.latitude + ',' +
    hass.states['person.maurizio'].attributes.longitude]]]

It's a pretty self-contained change and would open up a lot of possibilities without any external dependencies. What do you think? Would you consider adding it?

I would like this as well, as it means we can make one popup work for any number of cards, performing the original navigate action but also dynamically define an entity/state/attribute, for instance.

I am in that exact situation right now. Having a list of dynamically created cards, each that I would like to tap to open a popup, but I dont want to create X amount of the same popup to serve them. But since a bubble button action can only do one thing, there is no way to do this, not even through a script. At least none that I have found.
