This commit makes a number of improvements to the DiscourseJsProcessor:
1. Remove dependence on the out-of-date Ember template compiler from the ember-rails gem; switch to modern template compiler
2. Refactor to make use of a proper module system with `define`/`require`
3. Introduce `babel-plugin-ember-template-compilation` to enable inline hbs compilation
The `mini-loader` is upgraded to support relative lookup and `require.has`, so that these new JS packages work correctly.
We were already compiling the markdown bundle via ember-cli, but that version was only being used in the test environment. This commit improves the implementation, and updates the filename so it's also used in production.
This commit also
- Removes the vendored copy of `markdown-it.js` and fetches from node_modules instead
- Updates `pretty_text.rb` to remove the custom sprockets-manifest-parsing
- Removes `pretty-text-bundle.js`, which was only being used by `pretty_text.rb`
This adds a new framework for accessible dialogs that will eventually replace bootbox. Under the hood, it uses the a11y-dialog package and an in-repo Ember addon. See PR for usage details.
When `EMBER_CLI_PLUGIN_ASSETS=1`, plugin application JS will be compiled via Ember CLI. In this mode, the existing `register_asset` API will cause any registered JS files to be made available in `/plugins/{plugin-name}_extra.js`. These 'extra' files will be loaded immediately after the plugin app JS file, so this should not affect functionality.
Plugin compilation in Ember CLI is implemented as an addon, similar to the existing 'admin' addon. We bypass the normal Ember CLI compilation process (which would add the JS to the main app bundle), and reroute the addon Broccoli tree into a separate JS file per-plugin. Previously, Sprockets would add compiled templates directly to `Ember.TEMPLATES`. Under Ember CLI, they are compiled into es6 modules. Some new logic in `discourse-boot.js` takes care of remapping the new module names into the old-style `Ember.TEMPLATES`.
This change has been designed to be a like-for-like replacement of the old plugin compilation system, so we do not expect any breakage. Even so, the environment variable flag will allow us to test this in a range of environments before enabling it by default.
A manual silence implementation is added for the build-time `ember-glimmer.link-to.positional-arguments` deprecation while we work on a better story for plugins.
These packages are not published anywhere - they only exist for organizational purposes within this repository. Even so, it makes sense for their metadata to match that of the top-level discourse/discourse repository.
By default, in CI environments, Ember CLI does not output anything between "building..." and "cleaning up". Depending on configuration and hardware, Discourse asset builds can take upwards of 60s, and so this lack of output can make the build feel 'stuck'.
This commit introduces an addon which checks for CI mode, and then outputs status information periodically. The logic is very similar to Ember CLI's non-CI progress output implementation (https://github.com/ember-cli/ember-cli/blob/04a38fda2c/lib/models/builder.js#L183-L185).
This commit introduces a new `{{on-resize}}` modifier along with its companion `resize-observer` Service. These automatically take care of setting up the observer and handling cleanup.
The new plugin list is based on the ones currently used in our ember-cli pipeline, and are based on our official browser support policy.
This commit includes an update to the raw-handlebars compiler to remove the 'very hacky but lets us use ES6' code. It's served us well for the last 6 years, but the babel config changes broke it (`const` -> `let`). This commit takes the opportunity to refactor it to take a similar approach to PrettyText, by leaning on `mini-loader.js`.
`ember-modifier` provides APIs to write our own modifiers. `@ember/render-modifiers` provides some simple `did-insert`, `did-update` and `will-destroy` modifiers.
Upcoming `ember-modifier` deprecations have been set to 'throw' in our deprecation-workflow config to ensure we don't accidently start using deprecated behaviour.
This prevents a storm of deprecation messages in the developer console. We'll be working through and enabling these one-by-one over the coming weeks/months.
A dummy `discourse-ensure-deprecation-order` package is introduced to ensure that deprecation-workflow is loaded before `@ember/jquery`. This ensures that the `@ember/jquery`-triggered deprecation warnings can be silenced correctly
This also introduces a system for silencing CLI warnings.
