Add Variable Transform for obj to boolean

[dstrohl]

use Case,

• I have some sections of a complex card that I can enable or disable with a "true"/'false". what I would like to be able to do is something like, "if I have passed a variable with a link, then enable the button to that link, if I dont pass the link, disable it.

Potential Implementation:

the transform should basically work like:
if the value is a bool, return that, if it's a string, check for "true/false/yes/no/1/0" and return as appropriate.
otherwise return boolean(value) so, true if the string is not empty, or true for the int==1 etc...

Template:

declutter_templates:
  example_template:
    let:
      link_enable: '[[menu_link|bool]]'
    card:
      - type: custom:advanced-camera-card
        cameras:
          - camera_entity: '[[camera_entity]]'
        elements:
         - type: custom:advanced-camera-card-menu-icon
           enabled: '[[menu_link|bool]]'
           icon: mdi:link
           title: Link
           tap_action:
             action: navigate
             url: '[[menu_link]]'

Alternatives:
I know I could do this by defining the above "let:link_enable" as a variable and pass it, but it would be nice to have that auto-calculated.

This went out in 1.12.0 as the bool transform. enabled: '[[menu_link|bool]]' gives true when a link is set and false when it isn't, reading yes/no, on/off, 1/0 and real booleans the way you described. Closing this one.
