move SiteText.{head,top,bottom} to SiteCustomization 2015-01-14 18:52:42 +08:00			`<%- unless customization_disabled? %>`
FEATURE: Native theme support 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 2017-04-12 22:52:52 +08:00			`<%= raw theme_lookup("head_tag") %>`
