; To use PSD with Scheme 48:
|
|
; - Put (setq psd-using-slib nil) in your .emacs
|
|
; - Put this file in psd-directory
|
|
; - Remove (define *psd-tab-char* (integer->char 9)) from psd's read.scm
|
|
; - Do something horrible to primitives.scm to circumvent bug in
|
|
; Scheme 48's byte code compiler... those big long lists have to be
|
|
; split up: `((x ,x) ... (y ,y) ...) =>
|
|
; (let ((foo (lambda () `((x ,x) ...)))
|
|
; (bar (lambda () `((y ,y) ...))))
|
|
; (append (foo) (bar)))
|
|
|
|
; JAR's remarks:
|
|
; - The variable *PSD-PREVIOUS-LINE* was undefined (not consequentially so)
|
|
; - It doesn't support DELAY
|
|
; - It doesn't support the => syntax in COND
|
|
; - It doesn't like (write-char c port):
|
|
; ERROR: Wrong number of arguments to primitive procedure
|
|
; write-char
|
|
; - It would be awfully nice if there were a "quit" command
|
|
; - It leaves that little "=>" arrow in my buffer (except it's not
|
|
; really there, is it?)
|
|
; - It opens the source file multiple (maybe 6) times without
|
|
; closing it (not really a problem since the GC cleans these up, but
|
|
; sort of annoying)

|
|
;;;; SLIB interface to load psd files.
|
|
|
|
;;;; This is the file that takes care of loading psd into the Scheme
|
|
;;;; interpreter. If you want to modify psd to work with a particular
|
|
;;;; implementation, say "foo", this is the way to do it:
|
|
|
|
;;;; 1) Make a copy of the file "psd.scm" under the name "psd-foo.scm",
|
|
;;;; and modify it to load "primitives-foo.scm" instead of
|
|
;;;; "primitives.scm". You can also do other things.
|
|
;;;;
|
|
;;;; 2) Make a copy of the file "primitives.scm" under the name
|
|
;;;; "primitives-foo.scm", and modify the definitions in it to
|
|
;;;; know about the additional primitives in your implementation
|
|
;;;;
|
|
;;;; 3) When you now set the Emacs variable scheme-program-name to
|
|
;;;; "foo" and give the commands ``M-x run-scheme'' ``M-x psd-mode'',
|
|
;;;; you have a psd system that knows about your additional
|
|
;;;; primitives.
|
|
|
|
;;; this is not portable.
