Re: Emacs <-> Lua bridge

[michael schuldt]

Hi Eduardo,

I didn't use it for anything. It was something a professor let me do for credit while in university

because I was one unit short of the semester minimum.

I thought it would be useful as a faster and more mainstream way of programming Emacs,

but it turns out I enjoy Emacs Lisp more so I found no motivation to continue working on it.

For a while I stopped caring about what other people wanted to use and started writing tools in

Emacs Lisp...I've managed to find the middle ground since then.

This was also before modules got added to Emacs so that wasn't an option, it had to be compiled in.
Now that I'm thinking about it, I don't think this could be done with modules.
It extends core data structures and modifies things like garbage collection, I'm guessing
that's beyond the capability of a module.

Your mini-forth looks cool! I'll have to spend a bit more time checking it out...later.

Unfortunately I've been a bit too busy for the fun esoteric stuff lately.

Hi Michael,

this looks very interesting! What did you use it for?

Do you have plans to adapt your src/luamacs.c and make it into
something that can be loaded as a module? I am quite incompetent with
C, so I can't help you with the C side besides offering encouragement
and testing...

At this moment I have these short-term goals with the emlua module:

  1. Adapt https://github.com/edrx/edrxrepl to emlua,

  2. Use emlua to help me edit the files into which I throw
     interesting URLs compulsively when I am browsing the web in
     half-brain-dead mode,

One of my medium-term goals is to use emlua to turn Emacs into an
editor of derivation trees - see:

  http://angg.twu.net/dednat6/tug-slides.pdf

at this moment I have to edit them by hand, using rectangle commands
and picture mode, and some operations on them are hard to do... Note
that dednat6 has a mini-Forth inside, that is based on this:

  http://angg.twu.net/miniforth-article.html

And this may be somewhat related to the other stuff in your github
page...

  Cheers! =)
