You might store this value (a long) into -a class static variable, or a file static variable. I'll use a class -static variable in this example. - -I typically use code that works like this (untested code ahead): - -class Foo_class { - static long *Foo_smob_tag; - SCM obj; // representation as a scheme object, description comes later -} - -// call this once on startup -void init_Foo_class { - static scm_smobfuns type_rec; - - type_rec.mark = foo_mark; - type_rec.free = foo_free; - type_rec.print = foo_display; - type_rec.equalp = 0; - Foo_class::Foo_smob_tag = new int(scm_new_smob(type_rec)); -} - -When you want to export an object to scheme, you put a pointer to the -object itself in the cdr of the cell, and the tag in the car of the -cell. The code looks like this: - -// Is this a Foo? -static int -foo_p(SCM obj) -{ - return(SCM_NIMP(obj) && SCM_CAR(obj) == Foo_class::Foo_smob_tag); -} - -// given a Scheme representation, return, a C++ representation -static Foo_class * -foo_unbox(SCM obj) -{ - return((Foo_class*)SCM_CDR(obj)); -} - -// the SCM representation of the object is stored inside itself -// this will become useful when destructor gets called -static SCM -foo_box(Foo_class *foo) -{ - SCM_DEFER_INTS; - SCM_NEWCELL(foo->obj); - SCM_SETCAR(foo->obj, Foo_class::Foo_smob_tag); - SCM_SETCDR(foo->obj, (SCM)foo); - SCM_ALLOW_INTS; - return foo->obj; -} - -> C++ determines life time, so what is the strategy? - -What happens now when the destructor gets called? Lets set the cdr to -NULL, and then check for that in all of the primitive functions that -use your smob. We'll call this notion 'live'; a scheme object is -'live' if the C++ representation still exists, it's dead if the C++ -object is gone. You can still have references to dead objects in -scheme code; it's just an error to use them. This idea is stolen from -Emacs's handling of buffers ('buffer-live-p' and friends). - -Add another function, foo_live_p: - -static int -foo_live_p(SCM obj) -{ - return(foo_p(obj) && SCM_CDR(obj) != NULL); -} - -In you destructor, you need to do: - -~Foo_class() -{ - SCM_CDR(this->obj, NULL); -} - -When writing new primitives, now just check foo_live_p(). - -I hope the above helps, - --russ - - --- -"Even if you are on the right track, you'll get run over -if you just sit there." - --Will Rogers (1879-1935) - -* OUTLINE SETUP -.* .EMACS -;;; from outline.el -(defvar outline-font-lock-keywords - '(;; Highlight headings according to the level. - ;; must change this to allout node layout - ;;("^\\(\\*+\\)[ \t]*\\(.+\\)?[ \t]*$" - ("^\\([.]*[ ]*[*]\\)[ \t]*\\(.*\\)$" - (1 font-lock-string-face) - (2 (let ((len (- (match-end 1) (match-beginning 1)))) - (or (cdr (assq len '((1 . font-lock-function-name-face) - (2 . font-lock-keyword-face) - (3 . font-lock-comment-face)))) - font-lock-variable-name-face)) - nil t)) - ;; Highlight citations of the form [1] and [Mar94]. - ("\\[\\([A-Z][A-Za-z]+\\)*[0-9]+\\]" . font-lock-type-face)) - "Additional expressions to highlight in Outline mode.") - -(add-hook 'outline-mode-hook - '(lambda () - (setq font-lock-maximum-decoration t) - (setq font-lock-maximum-decoration t) - (make-local-variable 'font-lock-defaults) - (setq font-lock-defaults '(outline-font-lock-keywords t)) - (font-lock-mode global-font-lock-mode) - )) - -(require 'allout) -(outline-init 't) +[see http://www.cs.uu.nl/people/hanwen/lily-devel/index.html]
