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
This improves my DOMContentLoaded from 9s+ to less than 4s.
Pinging @SamSaffron on this because this was previously controversial.
This implementation adds the `@sourceURL` directive so chrome correctly
identifies the source files.
instead implement an aggressive anonymous cache that is stored in redis
this cache is sitting in the front of the middleware stack enabled only in production
TODO: expire it more intelligently when stuff is created
under rack cache we are able to serve 620reqs a second per thin (on my machine) before it 12 (on my machine)
reorganised so mini profilers can be cleanly disabled from config file
added caching for categories index
move production.rb to production.sample.rb
