;;; Commentary:
|
|
|
|
;; Highlight all the symbols in the Common Lisp ANSI Standard.
|
|
;; Adds font-lock regexes to lisp-mode.
|
|
|
|
;;;; Todo:
|
|
|
|
;; - Integrate better into `lisp-mode' (e.g. enable it by default).
|
|
;; - Distinguish functions from macros like `pushnew'.
|
|
|
|
;;; Code:
|
|
|
|
;; The list of built-in functions and variables was actually not
|
|
;; extracted from the standard, but from SBCL with the following
|
|
;; (Common Lisp) code:
|
|
|
|
;; (defvar *functions* nil)
|
|
;; (defvar *symbols* nil)
|
|
;; (defvar *types* nil)
|
|
|
|
;; (let ((pack (find-package :common-lisp)))
|
|
;; (do-all-symbols (sym)
|
|
;; (cond
|
|
;; ((not (eql pack (symbol-package sym))) nil)
|
|
;; ((fboundp sym) (pushnew sym *functions*))
|
|
;; ((find-class sym nil) (pushnew sym *types*))
|
|
;; (t (pushnew sym *symbols*)))))
