Setting these things up

Until everyone has merged my pull requests, you should get these:

https://github.com/abourget/webassets https://github.com/abourget/pyramid_webassets

Pending pull requests:

miracle2k/webassets#123 sontek/pyramid_webassets#3

Of course, you should learn a bit about WebAssets first :)

Minifying the dust core

When you install with "npm install" (see development.ini around here), look into node_modules/dust/dist.

You can also run:

make dust make min

from within node_modules/

Then you need the 'minmin' module from https://github.com/akdubya/minmin .. etc.. I didn't finish this

myapp.subscribers.py

from pyramid_webassets import IWebAssetsEnvironment

def add_renderer_globals(event):
    ...
    event['webassets'] = request.registry.queryUtility(IWebAssetsEnvironment)

myapp.templates.stuff.mako

<!--
   dust-core...min.js is taken from the dust repository, minified if you will.
 -->
<script type="text/javascript" src="/path/to/your/dust/dust-core-0.3.0.min.js"></script>

% for link in webassets['dust_templates'].urls():
  <script type="text/javascript" src="${link}"></script>
% endfor

pyramid.__init__.py

from webassets import Bundle

dust_bundle = Bundle('templates/dust',
                     filters="dustjs",
                     output="static/gen/dust_templates.%(version)s.js",
                     debug=False)
def main(...):
    config = Configurator(...)
    config.include('pyramid_webassets')
    config.add_webasset('dust_templates', dust_bundle)

    config.add_subscriber('myapp.subscribers.add_renderer_globals',
                          'pyramid.events.BeforeRender')
