Can I put Globals: in an external file?

ESPHome
1

I have a bunch of globals:

globals:
  - id: line1x
    type: int
    initial_value: '0'
  - id: line1y
    type: int
    initial_value: '0'

  - id: line2x
    type: int
    initial_value: '0'
  - id: line2y
    type: int
    initial_value: '50'

… that are cluttering up my view of the program. Can I cut 'n paste them into an external file?
Leaning on my Arduino IDE past, I would use the #include directive.

And indeed you can use the !include directive in your ESPHome YAML. It’s documented in the HA docs.

Not going too well… Thought it would be straight-forward. But no!
This is the head of my yaml file:

esphome:
  name: esp32s2-msp2807
  friendly_name: "ESP32 S2 msp2807"
  includes:
    - esp32s2-msp2807.h
    
esp32:
  board: lolin_s2_mini
  framework:
    type: arduino

If I miss-spell the includes: filename, the editor complains. So I guess that that bits right?
And this is esp32s2-msp2807.h (absolute path: /config/esphome/esp32s2-msp2807.h):

globals:
  - id: line1x
    type: int
    initial_value: '0'
  - id: line1y
    type: int
    initial_value: '0'

  - id: line2x
    type: int
    initial_value: '0'
  - id: line2y
    type: int
    initial_value: '50'

… and lastly, this is the section in the project file that references the globals: held in the header file:

display:
  - platform: ili9xxx
#
# truncated for brevity....
#
    lambda: |-
      it.printf(id(line1x), id(line1y), id(my_font), TextAlign::TOP_LEFT, "Temperature");
      it.printf(it.get_width(), id(line1y), id(my_font), TextAlign::TOP_RIGHT, " %.1f°C", id(outside_temp).state);

      it.printf(id(line2x), id(line2y), id(my_font), "Veh.Volts");
      it.printf(it.get_width(), id(line2y), id(my_font), TextAlign::TOP_RIGHT, " %.1fV", id(veh_volts).state);

      it.printf(id(line3x), id(line3y), id(my_font), "Veh.Amps");
      it.printf(it.get_width(), id(line3y), id(my_font), TextAlign::TOP_RIGHT, " %.1fA", id(veh_amps).state);

#
#et cetera....

As is, the HA editor reports that “line1x”, “line2x” can not be found?

You want tomput part of YAML file in another file - includes not the case to do it.
Use packages or <<: !include directive.

I posted the wrong link earlier, but if you want to extract multiple parts of the config, than as @Masterzz says, use packages:.

!include (as opposed to includes: is useful for replacing the value for a single key.
