3.2.3 MUF Macros
As with MPI, you can define macros — snippets of
reusable code called by a single statement — with MUF.
In fact, viewing defined macros and defining new ones is easier with
MUF than with MPI.
To view, define, or delete MUF macros, you need to be in
the MUF editor. You can use any program when invoking the
editor; the defined macros are available to all programs.
Viewing Macros: In the editor, type either s
(to see the long version of macro definitions) or a (to see
the abridged version).
(The example output below is slightly reformatted.)
====================================
> @edit tinker.muf
> s
abs Jessy ( i -- i' ) dup 0 < if -1 * then
after_match Jessy (d -- ) dup #-1 dbcmp swap #-2 dbcmp or if exit then
atodbref Jessy ( s -- d ) "" "#" subst atoi dbref
.
. ( .... entries omitted .... )
.
wizard? Jessy ( -- i ) "W" flag?
yes? Jessy ( s -- i ) ( checks that string starts with y ) 1
strcut pop "y" stringcmp not
End of list.

====================================
Defining Macros: In the editor (but not while you are inserting
code), type def <macro name> <macro
definition>.
====================================
> @edit tinker.muf
> def nukestack ( x..x' -- ) begin depth while pop repeat
Entry created.
====================================
Deleting Macros: Only wizards can delete macros, so, if you
are a non-wizard Mucker entering macros, be sure you have it right
when you enter it. If you are a wizard and want to delete a macro, type
<macro name> kill while in the editor.
====================================
> @edit tinker.muf
> nukestack kill
Macro entry deleted.
