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			`<%= theme_lookup("head_tag") %>`

PERF: remove 10-20ms of work from every page view <% s=Time.now; main_app.categories_path main_app.guidelines_path main_app.tos_path main_app.privacy_path p (Time.now-s)*1000%> Returns 10-20ms consistently on i7-4770k, on shared hosts the cost could easily reach 40ms This code simply calculates the strings /categories /guidelines /tos /privacy It is ludicrous to spend this enormous amount of work just to calculate 4 strings. I do not know if this is something specific about Discourse or a bug in Rails (I tried without the main_app prefix and got similar results), regardless we can got to avoid these _path APIs for now Discovered this when running a flamegraph on our home page. 2016-01-21 19:43:56 +08:00			`<%= link_to t('js.filters.categories.title'), path("/categories") %>`
