emacs 25 plugins for haskell

=========================

UPDATE

======

pretty much obsoleted by https://github.com/knupfer/haskell-emacs

left up in case i want to mine it for code later.

this is intended as a prototype (my ultimate goal is to hook up

http://github.com/mwotton/dustme up to elisp), but I'll leave this

here as a minimal example of how to call haskell from emacs.

Usage

=====

First, get emacs 25. This won't work with anything else.

Make a note of where it is, then edit stack.yaml:

```

extra-include-dirs:

  - ../../emacs/src

  ```

This will let ghc find the all-important emacs-module.h.

(There are some other important settings in stack.yaml, like the one to enable -fPIC

on a stack-wide basis.)

```

stack install --local-bin-path=SOMEDIRECTORY

```

This should install emacsplugin.so into the given directory.

I then run "emacs -Q -L SOMEDIRECTORY" (-Q because I don't want to run

my normal setup stuff, -L SOMEDIRECTORY to bring the module into

scope.)

We then evaluate

```

(require 'emacsplugin)

(mymod-test)

```

in a lisp buffer: mymod-test should return the result of multiplying

12 by 2 in Haskell. Not earthshattering, admittedly, but I'm currently

working on how to do marshalling.

Thanks

======

While I didn't end up using his code for marshalling, Niklas Hambüchen's

[call-haskell-from-anything](https://github.com/nh2/call-haskell-from-anything)

was extremely useful in working out how to build a .so file in

Haskell.

Thanks also to Aurélien Aptel for his explanation of the new [emacs

module system](http://diobla.info/blog-archive/modules-tut.html) and

how to call it from C.
