This feature introduces the concept of themes. Themes are an evolution
of site customizations.
Themes introduce two very big conceptual changes:
- A theme may include other "child themes", children can include grand
children and so on.
- A theme may specify a color scheme
The change does away with the idea of "enabled" color schemes.
It also adds a bunch of big niceties like
- You can source a theme from a git repo
- History for themes is much improved
- You can only have a single enabled theme. Themes can be selected by
users, if you opt for it.
On a technical level this change comes with a whole bunch of goodies
- All CSS is now compiled using a custom pipeline that uses libsass
see /lib/stylesheet
- There is a single pipeline for css compilation (in the past we used
one for customizations and another one for the rest of the app
- The stylesheet pipeline is now divorced of sprockets, there is no
reliance on sprockets for CSS bundling
- CSS is generated with source maps everywhere (including themes) this
makes debugging much easier
- Our "live reloader" is smarter and avoid a flash of unstyled content
we run a file watcher in "puma" in dev so you no longer need to run
rake autospec to watch for CSS changes

# Cheat and bypass Rails in development mode if the client attempts to download a static asset
|
|
# that's already been downloaded.
|
|
#
|
|
# Also ensures that assets are not cached in development mode. Around Chrome 29, the behavior
|
|
# of `must-revalidate` changed and would often not request assets that had changed.

# To use, include in your project and add the following to development.rb:

|
|
# require 'middleware/turbo_dev'
|

# config.middleware.insert 0, Middleware::TurboDev
