Prior to this commit, we didn't have RTL versions of our admin and plugins CSS bundles and we always served LTR versions of those bundles even when users used an RTL locale, causing admin and plugins UI elements to never look as good as when an LTR locale was used. Example of UI issues prior to this commit were: missing margins, borders on the wrong side and buttons too close to each other etc.
This commit creates an RTL version for the admin CSS bundle as well as RTL bundles for all the installed plugins and serves those RTL bundles to users/sites who use RTL locales.
This PR is a major change to Sass compilation in Discourse.
The new version of sass-ruby moves to dart-sass putting we back on the supported version of Sass. It does so while keeping compatibility with the existing method signatures, so minimal change is needed in Discourse for this change.
This moves us
From:
- sassc 2.0.1 (Feb 2019)
- libsass 3.5.2 (May 2018)
To:
- dart-sass 1.58

SCSS files have been migrated automatically using `sass-migrator division app/assets/stylesheets/**/*.scss`
Previously the stylesheet cachebusting hash was based on the maximum mtime of files. This works well in development and during in-container updates (e.g. via docker_manager). However, when a fresh docker image is created for each deploy, the file mtimes will change even if the contents has not.
This commit changes the production logic to calculate the cachebuster from the filenames and contents of the relevant assets. This should be consistent across deploys, thereby improving cache hits and improving page load times.
Previously, when the array had both nil and string values it returned the error "comparison of NilClass with String failed". Now I added the `.compact` method to prevent this issue as per @martin-brennan's suggestion https://github.com/discourse/discourse/pull/18431#discussion_r984204788
Without this parameter, requests for sourcemaps on shared-CDN multisites will not be routed to the correct database, resulting in a 404.
The stylesheet content now depends on the site hostname, so the hostname has been added to the digest.
* File.exists? is deprecated and removed in Ruby 3.2 in favor of
File.exist?
* Dir.exists? is deprecated and removed in Ruby 3.2 in favor of
Dir.exist?
Take 2 of https://github.com/discourse/discourse/pull/13466.
Fixes a few issues with the original PR:
- color definition stylesheet target now includes the theme id, to avoid themes set to use the default color scheme loading the same stylesheet
- changes the internal cache key for color definition stylesheet to reset the pre-existing cache
Before this change, calling `StyleSheet::Manager.stylesheet_details`
for the first time resulted in multiple queries to the database. This is
because the code was modelled in a way where each `Theme` was loaded
from the database one at a time.
This PR restructures the code such that it allows us to load all the
theme records in a single query. It also allows us to eager load the
required associations upfront. In order to achieve this, I removed the
support of loading multiple themes per request. It was initially added
to support user selectable theme components but the feature was never
completed and abandoned because it wasn't a feature that we thought was
worth building.
