When returning the customRenderFn from within buildCustomMarkdownCookFunction
for custom markdown engines (such as the one used by the [chat] transcripts)
we were not hoisting/unhoisting the `html_raw` tokens created by the
transcript, which meant that opts.discourse.hoisted could end up in
a state where it was null, and which caused errors and general unpleasantness.
Instead, we can just call the `cook` function that is already exported
from discourse-markdown-it, that takes care of what we did previously
plus the hoisting.
There is a companion chat commit that adds tests for this, there are
no custom markdown engine usages in core to test with.
This option will make it so the [quote] bbcode will always
include the HTML link to the quoted post, even if a topic_id
is not provided in the PrettyText#cook options. This is so
[quote] bbcode can be used in other places, like chat messages,
that always need the link and do not have an "off-topic" ID
to use.
Allows to write custom code blocks:
```
```mermaid height=200,foo=bar
test
```
```
Which will then get converted to:
```
<pre data-code-wrap="mermaid" data-code-height="200" data-code-foo="bar">
<code class="lang-nohighlight">
test
</code>
</pre>
```
This commit adds a requestCustomMarkdownCookFunction function
to the `helper` that is provided to custom markdown rules
via their `setup` function.
The way this works is that once the default markdown engine that
we use for cooking posts has been set up, we loop through all
of the callbacks registered by `requestCustomMarkdownCookFunction`
and call `_buildCustomMarkdownCookFunction`. This creates
a new markdown engine using many of the same settings as the
default one, but will allow for the following options to be
changed by the markdown rule requesting the custom function:
* featuresOverride - The markdown-it features to allow for the engine
* markdownItRules - The markdown-it rules to allow for the engine
After this engine is set up a render function which renders + sanitizes
the output is returned for use by the markdown rule.
The use case for this API is mainly for block BBCode markdown rules
which want to render their content with a limited subset of the
markdown features/rules. Our initial use case for this is chat message
quoting.
This commit also does some minor refactoring of discourse-markdown-it
to accommodate this new engine building.
Sometimes plugins need to have additional data or options available
when rendering custom markdown features/rules that are not available
on the default opts.discourse object. These additional options should
be namespaced to the plugin adding them.
```
Site.markdown_additional_options["chat"] = { limited_pretty_text_markdown_rules: [] }
```
These are passed down to markdown rules on opts.discourse.additionalOptions.
The main motivation for adding this is the chat plugin, which currently stores
chat_pretty_text_features and chat_pretty_text_markdown_rules on
the Site object via additions to the serializer, and the Site object is
not accessible to import via markdown rules (either through
Site.current() or through container.lookup). So, to have this working
for both front + backend code, we need to attach these additional options
from the Site object onto the markdown options object.
Previously only `<div>one top element</div>` was allowed because we use `firstChild` instead of `children`.
We also want `<div>one</div><div>two</div>` to work with this method.
This commit extends the options which can be passed to
`PrettyText.markdown` so that which Markdown-it rules and Discourse
Markdown plugins to be used when rendering a text can be customizable.
Currently, this extension is mainly used by plugins.
It was not clear that replace watched words can be used to replace text
with URLs. This introduces a new watched word type that makes it easier
to understand.
1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`
…so setting it to anything at all, for any type of request doesn't make sense (anymore)
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
* FIX: Cache missing inline oneboxes
Some inline oneboxes were not cached when the server did not return an
answer for an URL and the queried URL and the absolute URL were
different.
For example, if user typed www.example.com, the client asked the server
for http://www.example.com and if the server returned an empty response,
then the client would keep requesting an inline onebox everytime the
composer changed.
In other words, the key used for reading (the absolute URL) and the one
used for writing (the URL as typed by the user) were not the same when
the server returned an empty response.
* DEV: Check cache before making request
There is another cache check in PrettyText, but that is not enough if
multiple requests are pending. This problem was made obvious in tests,
but can happen for users with slow connections.
Note that this commit is also fixing various mistakes in emojis.
Some of them have been fixed manually in db.json/data.js/groups.json and will need to be fixed in emoji-db gem.
This is not a security issue because regular users are not allowed to insert FA icons anywhere in the app. Admins can insert icons via custom badges, but they do have the ability to create themes with JS.
This commit includes other various improvements to watched words.
auto_silence_first_post_regex site setting was removed because it overlapped
with 'require approval' watched words.
Previously we would always take the first image in a post to use as the
thumbnail. On media-heavy sites, users may want to manually select a
specific image as the topic thumbnail. This commit allows this to be
done via a `|thumbnail` attribute in markdown.
For example, in this case, bbb would be chosen as the thumbnail:
```

We want to wrap the `Ember.run.debounce` function and internally call `Ember.run` instead when running tests.
This commit changes discourseDebounce to work the same way as `Ember.run.debounce`.
Now that `discourseDebounce` works exactly like `Ember.run.debounce`, let's replace it and only use `DiscourseDebounce` from now on.
Move debounce to discourse-common to be able to reuse it in different bundles
Keep old debounce file for backwards-compatibility
- frowning was using slighty_frowning
- slightly_frowning was using frowning
- grinning_face_with_smiling_eyes was not defined
- fronwing_face_with_open_mouth was not defined
Adding a video in composer and then continuing to type into it will make the
video element flicker and restart playback on every keystroke, as the preview
is rendered. In certain configurations, this can lead to some performance
problems too.
Onebox already does the same for external videos.
eslint --fix is capable of fix it automatically for you, ensure prettier is run after eslint as eslint --fix could leave the code in an invalid prettier state.
Before this patch, discourse-markdown depended on the modules in its
bundle being defined in a specific order or it wouldn't load properly.
Now, any file in the bundle can export a `priority` const (default 0)
and files will be loaded in order of ascending priority instead. This
allows us to use a bundle packaged in any order we want.
