Hostname can vary per-site on a multisite cluster, so this change requires converting the compiler_version from a constant into a class method which is evaluated at runtime. The value is stored in the theme DistributedCache, so performance impact should be negligible.
We were sharing `Discourse` both as an application object and a
namespace which complicated things for Ember CLI. This patch
moves raw templates into `__DISCOURSE_RAW_TEMPLATES` and adds
a couple helper methods to create/remove them.
* DEV: Use Ember 3.12.2
* Add Ember version to ThemeField's DEPENDENT_CONSTANTS
* DEV: Use `id` instead of `elementId` (See: https://github.com/emberjs/ember.js/issues/18147)
* FIX: Don't leak event listeners (bug introduced in 999e2ff)
Previously theme translations were loaded along with other plugin API scripts. These run after pre-initializers and initializers when the app boots. This commit moves theme translation loading into pre-initializers, so their behaviour matches core translations more closely.
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.
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`.
* FEATURE: detect theme errors and catch them
* Bump COMPILER_VERSION
* Feedback
* Override eslint no console for one line
* Can't use our ajax method
* remove emoji from translation file
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
Theme developers can include any number of scss files within the /scss/ directory of a theme. These can then be imported from the main common/desktop/mobile scss.
* First take
* Add support for sprites in themes
Automatically register any custom icons added via themes or plugins
* Fix theme sprite caching
* Simplify test
* Update lib/svg_sprite/svg_sprite.rb

* Fix /svg-sprite/search request
If a theme setting contained invalid SCSS, it would cause an error 500 on the site, with no way to recover. This commit stops loading theme settings in the core stylesheets, and instead only loads the color scheme variables. This change also makes `common/foundation/variables.scss` available to themes without an explicit import.
New `about.json` fields (all optional):
- `authors`: An arbitrary string describing the theme authors
- `theme_version`: An arbitrary string describing the theme version
- `minimum_discourse_version`: Theme will be auto-disabled for lower versions. Must be a valid version descriptor.
- `maximum_discourse_version`: Theme will be auto-disabled for lower versions. Must be a valid version descriptor.
A localized description for a theme can be provided in the language files under the `theme_metadata.description` key
The admin UI has been re-arranged to display this new information, and give more prominence to the remote theme options.
- Themes can supply translation files in a format like `/locales/{locale}.yml`. These files should be valid YAML, with a single top level key equal to the locale being defined. For now these can only be defined using the `discourse_theme` CLI, importing a `.tar.gz`, or from a GIT repository.
- Fallback is handled on a global level (if the locale is not defined in the theme), as well as on individual keys (if some keys are missing from the selected interface language).
- Administrators can override individual keys on a per-theme basis in the /admin/customize/themes user interface.
- Theme developers should access defined translations using the new theme prefix variables:
JavaScript: `I18n.t(themePrefix("my_translation_key"))`
Handlebars: `{{theme-i18n "my_translation_key"}}` or `{{i18n (theme-prefix "my_translation_key")}}`
- To design for backwards compatibility, theme developers can check for the presence of the `themePrefix` variable in JavaScript
- As part of this, the old `{{themeSetting.setting_name}}` syntax is deprecated in favour of `{{theme-setting "setting_name"}}`
* FEATURE: allow plugins and themes to extend the default CSP
For plugins:
```
extend_content_security_policy(
script_src: ['https://domain.com/script.js', 'https://your-cdn.com/'],
style_src: ['https://domain.com/style.css']
)
```
For themes and components:
```
extend_content_security_policy:
type: list
default: "script_src:https://domain.com/|style_src:https://domain.com"
```
* clear CSP base url before each test
we have a test that stubs `Rails.env.development?` to true
* Only allow extending directives that core includes, for now
