Currently when generating a onebox for Discourse topics, some important
context is missing such as categories and tags.
This patch addresses this issue by introducing a new onebox engine
dedicated to display this information when available. Indeed to get this
new information, categories and tags are exposed in the topic metadata
as opengraph tags.
The lint warnings were:
```
inline-block is ignored due to the float. If 'float' has a value other than 'none', the box is floated and 'display' is treated as 'block'
scss(propertyIgnoredDueToDisplay)
```
- Sets `https://www.mixcloud.com` as a `requires_iframe_origins` to allow the iframe content to be displayed
- Attempts to render something approximating the Mixcloud content in the preview pane of the Composer, rather than just displaying a large version of the artwork associated with the link
We are no longer able to display the image returned by Instagram directly within a Discourse site (either in the composer, or within a cooked post within a topic), so:
- Display an image placeholder in the composer preview
- A cooked post should use an iframe to display the Instagram 'embed' content
* FIX: Improve GitHub folder regexp in Onebox
It used to match any GitHub URL that was not matched by the other GitHub
Oneboxes and it did not do a good job at handling those. With this
change, the generic Onebox will handle the remaining URLs.
* FEATURE: Add Onebox for GitHub Actions
* FEATURE: Add Onebox for PR check runs
* FIX: Remove image from GitHub folder Oneboxes
It is a generic, auto-generated image which does not provide any value.
* DEV: Add tests
* FIX: Strip HTML comments from PR body
Not all videos can be rendered everywhere because some browser may be
missing some codecs. This commit adds a notice on top of video to let
the user know about it.
This commit also updates github’s body onebox styles in Discourse core:
- full width
- prevents show-more btn to trigger vertical scrolling
- makes text standout less and slightly bigger
* fixed header/favicon's vertical alignment
* slightly increased header margin
* made the onebox padding symmetrical
* increased the right margin on small image elements
* removed extraneous pre bottom margin
* FEATURE: display error if Oneboxing fails due to HTTP error
- display warning if onebox URL is unresolvable
- display warning if attributes are missing
* FEATURE: Use new Instagram oEmbed endpoint if access token is configured
Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:
- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode
The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

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.
