|
;; 2010-10-08 by Yannick Kalantzis v0.2
|
|
;; Change syntax table: decimal numbers are words, mathematical
|
|
;; operators are punctuation. `@' and `#' are symbols.
|
|
;; Better font-lock for var, varexo, and parameters declaration,
|
|
;; and for macrocommands.
|
|
;; Add new keybinding for comment/uncomment: C-c ;
|
|
;;
|
|
;; 2010-09-07 by Yannick Kalantzis
|
|
;; Minor changes. Add `require'. Add builtin operators `;' and `='.
|
|
;; Highlight lags and leads.

|
;; 2010-09-06 by Yannick Kalantzis v0.1
|
|
;; Created.
|
|
;; Reproduces Xah Lee's instructions. See
|
|
;; <http://xahlee.org/emacs/elisp_syntax_coloring.html>. Very basic
|
|
;; syntax highlighting: comments, some keywords.
