This commits adds the ability to add a header to the embedded comments
view. One use case for this is to allow `postMessage` communication
between the comments iframe and the parent frame, for example, when
toggling the theme of the parent webpage.
A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
Previous to this change if any of the assets were not allowed extensions
they would simply be silently ignored, this could lead to broken themes
that are very hard to debug
Running `update_from_remote` and `save!` cause a number of side-effects, including instructing all clients to reload CSS files. If there are no changes, then this is wasteful, and can even cause a 'flicker' effect on clients as they reload CSS.
This commit checks if any updates are available before triggering `update_from_remote` / `save!`. This should be much faster, and stop the 'flickering' UX from happening on every themes:update run.
It also improves the output of the command to include the from/to commit hashes, which may be useful for debugging issues. For example:
```
Checking 'Alien Night | A Dark Discourse Theme' for 'default'... already up to date
Checking 'Star Wars' for 'default'... updating from d8a170dd to 66b9756f
Checking 'Media Overlay' for 'default'... already up to date
```

`auto_update` is true by default at the database level, but it doesn't make sense for `auto_update` to be true on themes that are not imported from a Git repository.
Checking for remote should cleanup after itself. Currently each check litters
the /tmp filesystem with checkouts. This patch ensures that update checks
keep the system a bit tidier.
There are three modifiers:
- serialize_topic_excerpts (boolean)
- csp_extensions (array of strings)
- svg_icons (array of strings)
When multiple themes are active, the values will be combined. The combination method varies based on the setting. CSP/SVG arrays will be combined. serialize_topic_excerpts will use `Enumerable#any`.
Note:
```
def foo(bar: 1)
end
foo({bar: 2})
# raises a deprecation, instead use:
foo(**{bar: 2})
```
Additionally when matching regexes always use strings. It does not make
sense to match a non string to a regex.
* FEATURE: Adds an extra protection layer when decompressing files.
* Rename exporter/importer to zip importer. Update old locale
* Added a new composite class to decompress a file with multiple strategies
* Set max file size inside a site setting
* Ensure that file is deleted after compression
* Sanitize path and files before compressing/decompressing
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.
The client-side theme-selector would always apply the first in a series of file change notifications. This has been fixed, so it now applies the most recent notification.
Duplicate notifications were being sent because
- The remote_theme autosave was causing every change notification to be doubled
- Color scheme change notifications were being sent every time a theme was uploaded, even if the colors were unchanged
These duplicate notifications have been fixed, and a spec added to ensure it does not regress in future
Theme developers can now add any of the transformed color variables to their color scheme in about.json. For example
```
"color_schemes": {
"Light": {
"primary": "333333",
"secondary": "ffffff",
"primary-low": "ff0000"
}
},
```
would override the primary-low variable when compiling SCSS for the color scheme. The primary-low variable will also be visible in administrator color palette UI.
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.
Currently the theme is matched by name, which can be fragile when there are many themes with the same name. This functionality will be used by the next version of theme CLI.
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.
This issue is caused by the filename restrictions in `OptimizedImage#ensure_safe_paths!`. Difficult to add a test for this because image optimization is bypassed in test mode.
- 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: add branch option to remote theme import
* FIX: Add missing variable in params
* FIX: Add missing param for import_theme method
* SPEC: Add test methods for branch support in git import
* FIX: Add missing space to scss style
* Do not assume default branch as master
* Change branch field placeholder
* FIX: add missing div start tag
