fn()

fn([<obj>/]<function name>[, <arg0>[, ... , <argN>]])

fn() executes the built-in/hardcoded function <function name>, even if the function has been deleted or overridden with @function. It is primarily useful within @functions that override built-ins in order to be able to call the built-in.

Example:

&BRIGHT_PEMIT #10=fn(pemit,%0,-->[ansi(h,%1)])
@function/delete PEMIT
@function PEMIT=#10,BRIGHT_PEMIT
think pemit(me,test)
-->test   (in highlighted letters)

To restrict the use of fn() to @functions only (to prevent players from skirting softcoded replacements), use @function/restrict fn=userfn.

To prevent deleted functions from being used with fn(), @function/disable them prior to deleting.

Executor selection

If <obj> is specified, the built-in function will be executed as <obj>, rather than as the object which called fn(). This is useful when using fn() to replace a side-effect function, to ensure priviledge checks, etc, are done correctly. You must control <obj>, or (if function side effects are disabled) must be see_all.

When an <obj> is given, debug information is automatically suppressed when evaluating the built-in function.

Example:

&BRIGHT_PEMIT #10=fn(%@/pemit, %0, -->[ansi(h,%1)])
@function/delete PEMIT
@function PEMIT=#10, BRIGHT_PEMIT
@lock/page *Mike=!=*Padraic

> think pemit(*Mike,test)
(nothing happens)
