After fingerprinting and to mimic Rails, gzip the CSS & JS assets found in dist/ with a ".gz" appended extension.

We probably want to do a few things here:

1. Delete the non-fingerprinted files
2. Improve the grunt-rails-asset-digest package to support the Rails 4 JSON manifest file.

If the rubygem did a lineman build and pulled in the assets under app/assets/javascripts and app/assets/stylesheets, we'd be able to avoid all the rails-mimicking.

So if the gem could wrap the assets:precompile task (@searls makes hand-wavy 👏 motion), then it might work like this (only thinking about JS & CSS support):

1. rake assets:precompile is invoked, but before we let it run:
2. Locate the project, whine if the Lineman project isn't found. (start with just filepath support)
3. Run npm install in the project, blow up if node isn't found with instructions on installing node.
4. Run lineman build with cwd in the project; if the lineman bin isn't on PATH, then use the <project>/node_modules/.bin/lineman bin.
5. Copy the contents of dist/js/**/* into app/assets/javascripts/lineman
6. Copy the contents of dist/css/**/* into app/assets/stylesheets/lineman
7. Invoke the wrapped assets:precompile task
8. Delete app/assets/javascripts/lineman and app/assets/stylesheets/lineman.

So this way if someone is working on a Rails template, they'd use a script include tag for lineman/app for the main JS bundle. Rails will see this during precompile time and be sure to create that file as a manifest into public/assets.

One potentially confusing point here is that if nothing in the rails app requires any lineman/* JS or CSS paths, then nothing of the lineman app will get built into public/assets. It's a feature, but a confusing one for first time users, I'm sure..

I think we should disable the pages task for lineman-rails projects by default, since its most likely outcome will be to confuse users and we won't have a good way to bring that static HTML over to public/ in a sane way that wouldn't throw off normal people (especially if the default file is "index.html")
