Themes can now declare custom colors that get compiled in core's color definitions stylesheet, thus allowing themes to better support dark/light color schemes.
For example, if you need your theme to use tertiary for an element in a light color scheme and quaternary in a dark scheme, you can add the following SCSS to your theme's `color_definitions.scss` file:
```
:root {
--mytheme-tertiary-or-quaternary: #{dark-light-choose($tertiary, $quaternary)};
}
```
And then use the `--mytheme-tertiary-or-quaternary` variable as the color property of that element. You can also use this file to add color variables that use SCSS color transformation functions (lighten, darken, saturate, etc.) without compromising your theme's compatibility with different color schemes.
This fixes an issue where a non-default theme set to use the base color
scheme (i.e. the theme had an empty `color_scheme_id`) was loading the
default theme's color scheme instead.
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets.
This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.
Syntax highlighting is a CPU-intensive process which we run a lot while rendering posts and while using the composer preview. Moving it to a background worker releases the main thread to the browser, which makes the UX much smoother.
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

- Eliminate superfluous "author wrote" block
- Eliminate block-quote for all posts
- Move participant count and reply count to 1 line
- Prioritize name over username if forum requests
- Use fabrication in list controller spec to speed up spec
When looking for the first paragraph with content in a post,
it was matching the lightboxed image paragraph as "<p></p>".
Fix that and other potential empty paragraphs with the
p:not(:empty) selector.
Add a new selector to find the image links in lightboxed
images as valid content for emails.
Extracted from #8772
This will allow developers (in rails development mode only) to log pre-loaded JSON app data to the browser console for inspection.
The data-vocabulary.org schema is being deprecated.
We're now using the BreadcrumList data from the latest and greatest schema.org.
FIX: categories_breadcrumb helper to support more than 2 levels of categories.
The following methods have long been deprecated in ruby due to flaws in their implementation per http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-core/29293?29179-31097:
URI.escape
URI.unescape
URI.encode
URI.unencode
escape/encode are just aliases for one another. This PR uses the Addressable gem to replace these methods with its own encode, unencode, and encode_component methods where appropriate.
I have put all references to Addressable::URI here into the UrlHelper to keep them corralled in one place to make changes to this implementation easier.
Addressable is now also an explicit gem dependency.
* FEATURE: Normalize the service worker route
Update cache headers so they are not immutable outside of the rails app
Add the ability to purge the service worker cache from localhost
Rails -> nginx will pass immutable flags so the file is cached until reloaded.
In most cases, nginx will have its cache flushed on rebuild (new image)
For those needing dynamic re-caching (such as upgrading via the UI),
a rake task for flushing the service worker script is provided
through `assets:flush_sw`
If a post starts with a post quote and has no other text content,
then the email excerpt was the name of the person quoted and
nothing else. The intention was to show the contents of the
first paragraph or div after the quote.
With this change, a quote followed by an image will use the
image as the excerpt. A quote followed by a onebox will use the
onebox.
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
We expect mini profiler only to show up on accounts that are flagged as
developer accounts.
Unfortunately there was a bypass on any controllers that mix in ApplicationHelper
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
When showing the native app banner, we include an app argument to automatically add the current site to the official DiscourseHub app. However, the app id can be changed via a hidden site setting, and when changed, that argument is no longer useful. This ensures the argument is only included for the official iOS app banner.
This adds a 1 minute rate limit to all JS error reporting per IP. Previously
we would only use the global rate limit.
This also introduces DISCOURSE_ENABLE_JS_ERROR_REPORTING, if it is set to
false then no JS error reporting will be allowed on the site.
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.
Customizations can be added and edited in Admin > Customize > Email Style.
Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.
As part of this work, RTL locales are now rendered correctly for all emails.
When both a cdn URL and an s3 cdn URL defined, subfolder paths were leaking
through to the s3 cdn URL. If we are replacing the cdn url with the s3_cdn url,
we also need to make sure that the subpath is removed as well, as it appears in
the original cdn url.
The test should give a fairly good gist of the situations - in subfolder
situations where s3_cdn and a cdn is defined:
`asset_path` returns the asset with a subfolder, in the form `{cdn_url}/{subfolder}/{asset_path}`
Currently this is being replaced to `{s3_cdn_url}/{subfolder}/{asset_path}`
I am proposing we change this to: `{s3_cdn_url}/{asset_path}` as it seems like
for s3_cdn urls we should not be carrying around app subfolder pathing anywhere
we are looking up s3 paths.
You can now add javascript files under `/javascripts/*` in a theme, and they will be loaded as if they were included in core, or a plugin. If you give something the same name as a core/plugin file, it will be overridden. Support file extensions are `.js.es6`, `.hbs` and `.raw.hbs`.
The spoiler alert plugin replaces spoiler text found in email excerpts with posts URL, which means it needs to have a reference to the post it's processing.
This change makes `email_excerpt` accepts an optional post param, which calls `PrettyText.format_for_email` which then triggers the `reduce_cooked` event that the plugin subscribes to.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
