Ecaml – Writing Emacs Plugins in OCaml

Considering the amount of code written out there for emacs making the original scripting language a second class citizen would be an enormous undertaking. Most other languages have taken years to convince people to upgrade (Python, Perl.. ) . I really don't think having elisp as a second class citizen would happen anytime soon.

Couldn't you try compiling OCaml or another language to Emacs lisp bytecode [0]?

Exactly, the elisp monoculture is a feature not a bug.

real world ocaml is pretty good: https://realworldocaml.org/

there's also a mooc that i've heard good things about: https://www.fun-mooc.fr/courses/parisdiderot/56002S02/sessio...

I like: http://caml.inria.fr/pub/docs/oreilly-book

Real world ocaml is not so complete, and light on subjects such as C interop.

I like my blog post to get you up to speed: http://hyegar.com/2015/10/20/so-youre-learning-ocaml/

In Emacs 25 you can write native plugins loaded dynamically at runtime. With this you can do it in OCaml instead of C. Of course you can write it in anything else that will expose the right C interface.
