ewwii call-fns

The call-fns command allows you to call Rhai functions directly from the command line. This can be useful for triggering specific functionality in your widget configuration without updating or interacting with the GUI.

Note: All variables created by poll or listen handlers will default to their initial values when calling functions. They cannot be preserved.

Example:

# Call a single Rhai function
ewwii call-fns "my_function(32, 21)"

# Call multiple functions
ewwii call-fns "first_function('string')" "second_function()"

This will execute the specified functions in the context of your current configuration.

Limitation: Main configuration

However, there is one limitation in call-fns. It can only see and call functions defined within your main configuration (i.e ewwii.rhai file).

Solution: Creating wrappers

But, there is one solution though! You can call external functions from functions defined in main.

Example:

// in external.rhai
fn awesome_fn() {
    print("Awesome fn triggered!");
}

// in ewwii.rhai
fn call_awesome_fn() {
    import "external" as external;
    external::awesome_fn();
}

Now you can run ewwii call-fns "call-awesome_fn()" and get "Awesome fn triggered!".
