emacs lisp in javascript?

[Thomas Lord]

Is it viable to implement GNU Emacs Lisp in
Javascript?   Has anyone explored the question
and gotten anywhere?

Thanks,

The other way around:
 Ejacs is a JavaScript interpreter for Emacs, written entirely in Emacs
   Lisp.

Well, the specific goal I had in mind was this:

Suppose that you could run GNU Emacs in any decent browser,
storing your files over the net -- in something similar
to DropBox or Google Drive.  The servers would be free software, 
with multiple providers, good terms of service,
and sane security features, unlike DropBox and Google
Drive.

Thanks!  That's a handy survey.

That makes it look not easy but definitely doable.

It would probably be easier to work on embedding emacs in a browser,
rather than dealing with writing an implementation of elisp in
javascript. It that vein, you might want to take a look at
https://github.com/stsquad/emacs_chrome .

Is there any advantage to implementing javascript interpreter in a
language like emacs lisp which is dynamic binding versus clisp or
scheme which is static binding ?

Quote from Steve Yegge:
,----------------------------------------------------------------------
| I had big plans for Ejacs. I was going to make it a full-featured,
| high-performance JavaScript interpreter, with all the Emacs internals
| surfaced as JavaScript native host objects, so you could write Emacs
| customizations using object-oriented programming. 
`----------------------------------------------------------------------

From reading the cited blog, I would guess that this was more a
personnal project from somebody who loves Emacs and Javascript and
started a project that made him learn much more about both.
