Auto-complete in template blocks?

[jasonmadigan]

Problem/Motivation

The HA VS Code Add-on used to provide auto-completion for keywords within template blocks. This hasn't been working now for me for some time, and can't recall when it last worked (couple of months ago?). Entity IDs are auto completed elsewhere in editor, but not in blocks.

For example, typing:

sensor.ket

shows matches for sensor.kettle if it were filled in in say, the name, unique_id fields. It is not auto-completing in the below multi-line state block below however.

sensor:
  - name: unaccounted_power
    unique_id: unaccounted_power
    unit_of_measurement: "W"
    device_class: power
    state_class: measurement
    state: >-
      {{
        (
        states('sensor.deye_sunsynk_sol_ark_load_power')|float(0)
        - states('sensor.garage_network_tasmota_energy_power')|float(0)
        - states('sensor.washing_machine_current_consumption')|float(0)
        - states('sensor.dryer_current_consumption')|float(0)
        - states('sensor.plug_desktop_current_consumption')|float(0)
        - states('sensor.office_network_energy_power')|float(0)
        - states('sensor.plug__office_laptop_current_consumption')|float(0)
        - states('sensor.kettle')|float(0)

I read #770 which looked similar, but I see that was resolved some time ago. I am running the latest addon (5.17.3).
