Elm filter for webassets
########################

Filter for compiling `Elm <http://elm-lang.org>`_ files using `webassets <http://webassets.readthedocs.org>`_.

Install
*******

::

    pip install webassets-elm

As of version 0.2.0, this plugin requires **Elm 0.19** or newer (building with ``elm make``).

If you need to build your Elm project with ``elm-make`` (Elm 0.18 and older), you can pin your ``webassets-elm`` package to version ``0.1.7``.

Basic usage
***********

.. code:: python

    from webassets.filter import register_filter
    from webassets_elm import Elm

    register_filter(Elm)

Settings
========

**Optionally** as an evironment variable you can have:

* ``ELM_BIN``: alternative path to ``elm`` if it is **not** available globally (e.g. ``node_modules/.bin/elm``).

* ``ELM_OPTIMIZE``: enable the Elm compiler optimization option. Recommended for production output.

* ``ELM_DEBUG``: enable the Elm compiler debug option.

Examples
========

Flask with `flask-assets <http://flask-assets.readthedocs.io/>`_
----------------------------------------------------------------

.. code:: python

    from flask import Flask
    from flask_assets import Bundle, Environment
    from webassets.filter import register_filter
    from webassets_elm import Elm

    app = Flask(__name__)

    register_filter(Elm)
    assets = Environment(app)

    elm_js = Bundle('elm/main.elm', filters=('elm',), output='app.js')
    assets.register('elm_js', elm_js)

Django with `django-assets <http://django-assets.readthedocs.org>`_
-------------------------------------------------------------------

.. code:: python

    from django_assets import Bundle, register
    from webassets.filter import register_filter
    from webassets_elm import Elm

    register_filter(Elm)

    elm_js = Bundle('elm/main.elm', filters=('elm',), output='app.js')
    register('elm_js', elm_js)
