This is amazing. Seems most things in elisp are covered. Here are some more that may be reasonable to add:

• define-global-minor-mode: This is an alias of define-globalized-minor-mode.
• define-inline: Inline function.

and things offerd by cl-lib:

• cl-defun: Function. An alias of it is defun*.
• cl-defgeneric and cl-defmethod: Define generic function and new method for a generic function.
• cl-defsubst: Inline function. An alias is defsubst*.
• cl-defmacro: Macro. An alias is defmacro*.
• cl-define-compiler-macro: Macro.

You can eval this in Emacs to get a list of callable symbols start with def or cl-def, with their documentation:

(let ((collection nil))
  (dolist (sym
           (append
            (all-completions "def" obarray)
            (all-completions "cl-def" obarray)))
    (when (fboundp (intern sym))
      (push sym collection)))
  (dolist (elt collection)
    (insert "\n")
    (insert (format "%-35s" elt))
    (when (documentation (intern elt))
      (insert (car (split-string
                    (documentation (intern elt)) "\n"))))))

Thank you.

In this cycle, I will not work on cl- prefix. The original lisp parser heavily replies token starting from "def".

I will add following items to this request as you suggested:

• define-global-minor-mode
• define-inline
• defun*
• defsubst*
• defmacro*

The rest of them will be supported in planed Sexp meta parser.

[masatake]

Added a test case including quote.
The changes are for emacs-lisp. So I don't touch test cases for Common Lisp here.
