$funcCall

Calls a user-defined function previously declared with $func[name;...]. The call is expanded inline at compile-time.

Syntax

$funcCall[funcName;arg1;arg2;...]

Parameters

Parameter	Description	Required
funcName	Name of the function to call (must match a $func definition)	Yes
arg1, arg2, …	Arguments passed to the function’s parameters	No

Description

$funcCall invokes a user-defined function. The function body is expanded at compile-time — all text, inline functions, and $funcArg references are resolved and inserted at the call site.

If the function uses $funcReturn, that value becomes the result. Otherwise, the accumulated text content of the function body is used.

Examples

Basic call with return

$func[greet;name]
$funcReturn[Hello $funcArg[name]!]
$funcEnd
$sendMessage[$funcCall[greet;World]]

Call with runtime placeholders

$func[say;msg]
$funcReturn[You said: $funcArg[msg]]
$funcEnd
$sendMessage[$funcCall[say;$username]]

At runtime: You said: <actual username>

Chaining calls

$func[wrap;x]
$funcReturn[[$funcArg[x]]]
$funcEnd
$func[bracket;v]
$funcReturn[{$funcArg[v]}]
$funcEnd
$sendMessage[$funcCall[wrap;$funcCall[bracket;hello]]]

Output: [{hello}]

Calling an undefined function

$sendMessage[$funcCall[notfound;test]]

Returns empty string with a diagnostic warning.

Notes

• The function must be defined before the call
• Calls are resolved at compile-time — not at runtime
• Max recursion depth: 10 calls
• If the function is not found, returns an empty string and emits a diagnostic
