Utility Functions

Dynamic Macros provides a few utility functions to make Dynamic Macros easier to write.

update()

The update() function allows to save variables across whitespaces (see Receiving Variables for more information). Example:

[gcode_macro MY_MACRO]
gcode:
    {% set a = 10 %}
    {% set b = update("b", 20) %}
    RESPOND MSG="A: {a}" # 10
    RESPOND MSG="B: {b}" # 20


    RESPOND MSG="A: {a}" # ""
    RESPOND MSG="B: {b}" # 20

get_macro_variables()

The get_macro_variables() function allows to retrieve all the variables from another macro in one line of code. Example:

[gcode_macro MY_SETTINGS]
variable_a: 10
variable_b: 20
gcode:
    RESPOND MSG="settings"

[gcode_macro GET_SETTINGS]
gcode:
    {% set settings = get_macro_variables("MY_SETTINGS") %}
    RESPOND MSG="Settings: {settings}"
    RESPOND MSG="A: {settings.a}"

update_from_dict()

The update_from_dict() function allows for saving the output of get_macro_variables() (or other dictionaries) across the whitespaces when Receiving Variables. Example:

[gcode_macro MY_SETTINGS]
variable_a: 10
variable_b: 20
gcode:
    RESPOND MSG="settings"

[gcode_macro GET_SETTINGS]
gcode:
    {% set settings = get_macro_variables("MY_SETTINGS") %}
    {% set settings = update_from_dict(settings) %}


    RESPOND MSG="A: {a}" # 10
    RESPOND MSG="B: {b}" # 20
