From 07367474c6d46511ab2dd9cb696c32785f500484 Mon Sep 17 00:00:00 2001 From: morioka Date: Sat, 22 May 1999 12:11:01 +0000 Subject: [PATCH] - Rename property `luna-member-index' to `luna-slot-index'. - Rearrangement to avoid byte-compiling problem. (luna-define-class-function): New function. (luna-define-class): Use `luna-define-class-function'. (luna-define-generic): Fixed. (luna-define-internal-accessors): New function. --- luna.el | 126 ++++++++++++++++++++++++++++++++++++++++----------------------- 1 file changed, 80 insertions(+), 46 deletions(-) diff --git a/luna.el b/luna.el index bc23bc5..646258f 100644 --- a/luna.el +++ b/luna.el @@ -47,6 +47,9 @@ If PARENTS is specified, TYPE inherits PARENTS.
