callFn()

function callFn(
   fn, 
   argsSubs?, 
scopedVariables?): Promise<unknown>;

Defined in: renderer/fns.ts:36

Executes an exposable function and resolves its arguments.

This is the core function execution mechanism of the runtime. It resolves arguments, supports nested function calls, variable access, and optional result assignment.

Parameters

Parameter	Type	Description
fn	ExposableFn	Function definition to execute
argsSubs?	Record<number, unknown>	Optional argument overrides (e.g. event injection)
scopedVariables?	Variables	-

Returns

Promise<unknown>

Promise resolving to the computed result

Remarks

Argument resolution supports:

• primitive values (string, number, boolean)
• variables (var)
• nested functions (fn)
• argument injection (arg)
• event overrides via argsSubs

Additional features:

• Access resolution via touchByAccess
• Result assignment via fn.as
• Nested execution with variable injection
