Is it possible to have an alias for the function name in Lisp?

Question

...just like packages do.

I use Emacs (maybe, it can offer some kind of solution).

For example (defun the-very-very-long-but-good-name () ...) is no

Answer 1

You could simply have a function that just calls another function.

Answer 2

you can use (defmacro ...) to alias a function

Answer 3

If your problem is that you can't remember a very long function name, but you remember PART of the name, that's what "apropos" is for. In my Emacs, I have "C-h a" bound to "hyper-apropos". You enter a substring of the symbol you're looking for, and it lists all the matches.

Answer 4

I dont know Emacs, but wouldn't (define shortname longnamefunctionblahblah) work?

Answer 5

You could use setf to assign the function to the function cell of another, for example:

(defmacro alias (new-name prev-name)
  `(setf (symbol-function ,new-name) (symbol-function ,prev-name))) 

Answer 6

You want defalias. (defalias 'newname 'oldname) will preserve documentation and even show "newname is an alias for `oldname'" when its documentation is requested.
