I took a different approach, which perhaps is of interest to
someone. I'll post it here for the record. This patch is a pure
elisp implementation and seems to work on linux, mac osx and
windows (provided that erlc is in the path).
;; Syntax check erlang source code on the fly (integrates with flymake).
;; Start using flymake with erlang by putting the following somewhere
;; in your .emacs file:
;; (require 'erlang-flymake)
;; Flymake is rather eager and does its syntax checks frequently by
;; default and if you are bothered by this, you might want to put the
;; following in your .emacs as well:
;; There are a couple of variables which control the compilation options:
;; * erlang-flymake-get-code-path-dirs-function
;; * erlang-flymake-get-include-dirs-function
;; * erlang-flymake-extra-opts
;; This code is inspired by http://www.emacswiki.org/emacs/FlymakeErlang.
There are a few differences that I've spotted. The previously
posted version adds include and code paths whereas mine are by
default empty (any takers? :-) ). They are configurable though.
I've used this in a setting where include and code paths are
stated in a special file within the application. I wrote
functions which produced lists of paths based on that file. The
following variables can be set to point at such functions:
* erlang-flymake-get-code-path-dirs-function and
The flags used to specify compiler warnings differ as well.
There's another variable that can be used to specify the options
one wants to use:
git fetch git://github.com/klajo/otp.git erlang-flymake
