Topic: version of acad.pgp as lisp?

[chthon]

g'day rjp..
wondering what nil does after the defun? as below;

Code: [Select]

;; RJP 2.9.2018 harvest stock PGP and convert to one line lisp list
(defun C:-3DCONFIG nil (command "_.-GRAPHICSCONFIG") (princ))
(defun C:-AR nil (command "_.-ARRAY") (princ))
(defun C:-ARM nil (command "_.-ACTUSERMESSAGE") (princ))
(defun C:-ARS nil (command "_.-ACTSTOP") (princ))etc - i wasn't able to find any documentation on this, any assistance
appreciated
tia, chthon

An empty list is considered nil thus:

(defun c:foo ()  (princ "\nfoo.") (princ))

(defun c:foo nil (princ "\nfoo.") (princ))

are equivalent to the interpreter (but not the eyes).

mp,
makes sense, this is the good thing about code,
thanks,

hi all, & thanks for your responses [i like the code snippet from Se7en]
the reason i am interested thus is that as a contractor, these crucial files are networked and locked, often with ambiguous non-standard aliases, guided by these threads;

i came up with this lsp version:  [attached]
time to overcome pgp's alias irregularity / regularity - with this pgp.lsp, usual function library is unaffected, & loaded from acad.lsp / accaddoc.lsp.
