|
||
;;; Commentary:
|
||
|
||
;; The major mode for editing Scheme-type Lisp code, very similar to
|
||
;; the Lisp mode documented in the Emacs manual. `dsssl-mode' is a
|
||
;; variant of scheme-mode for editing DSSSL specifications for SGML
|
||
;; documents. [As of Apr 1997, some pointers for DSSSL may be found,
|
||
;; for instance, at <URL:http://www.sil.org/sgml/related.html#dsssl>.]
|
||
;; All these Lisp-ish modes vary basically in details of the language
|
||
;; syntax they highlight/indent/index, but dsssl-mode uses "^;;;" as
|
||
;; the page-delimiter since ^L isn't normally a legal SGML character.
|
||
;;
|
||
;; For interacting with a Scheme interpreter See also `run-scheme' in
|
||
;; the `cmuscheme' package and also the implementation-specific
|
||
;; `xscheme' package.
|
||
|
||
;; Here's a recipe to generate a TAGS file for DSSSL, by the way:
|
||
;; etags --lang=scheme --regex='/[ \t]*(\(mode\|element\)[ \t
|
||
;; ]+\([^ \t(
|
||
;; ]+\)/\2/' --regex='/[ \t]*(element[ \t
|
||
;; ]*([^)]+[ \t
|
||
;; ]+\([^)]+\)[ \t
|
||
;; ]*)/\1/' --regex='/(declare[^ \t
|
||
;; ]*[ \t
|
||
;; ]+\([^ \t
