Unwrap all embeds with paragraph tags #4650

pierlon · 2020-05-04T17:01:04Z

Summary

There are inconsistencies with some embeds being wrapped with a <p> tag, and some not. We should strive towards having a uniform markup across all embeds.

Fixes #4450.
Fixes #4697.
Fixes #4754.
Fixes #4757.

Should this verify the script is the expected one? Namely, one with the src of https://videopress.com/videopress-iframe.js?

Come to mention it, what does this script do? It appears to be handling resizing. Is resizing something that we're missing? Or is resizing not needed in an AMP context? If it is, we should contact WordPress.com about emitting the AMP resizing messages.

Before you going, I suggest refactoring the code to put more recurring logic into the base embed handler.

Basically, what this does is provide more of "Template Method Pattern" approach to dealing with embeds, where the base embed handler lays down a framework of how to deal with a typical embed. The individual embeds can still override any step that doesn't directly fit within the general framework, but overall, there'll be less code, needing less testing, as a lot of them will be perfectly happy with this default framework if it is well chosen.

So, if you look at my comments, I'd suggest using sanitize_raw_embeds() as one of the steps in this template, with its default implementation (using is_raw_embed() and sanitize_raw_embed(), but minus the hard-coded strings) just being implemented once within the base embed handler.

As uncovered in https://github.com/rtCamp/themes/pull/3/files#r423249922, it may make sense in this create_amp_instagram_and_replace_node() method to preserve some inline styles from the $node to copy onto $new_node. In particular, border-radius: 3px; border: 1px solid rgb(219, 219, 219);.

Nevertheless, this is is probably not something we should be concerned with. In fact, it's probably actually an AMP issue where amp-instagram should be applying those styles. So nevermind!

Good to see much of the duplicated code being factored away.

There are a couple areas that need to be addressed before this is ready:

It is relatively common for developers to create their own embed handlers, slightly less common I'd say to creating custom sanitizers. Sanitizers and embed handlers are two key ways the plugin is extended. Therefore, it is critical that backwards-compatibility be maintained for existing embed handlers (and sanitizers).

Additionally, it is important that any APIs introduced on the base method be ergonomic for developers to use when they extend the embed base handler. For example, some of the methods take a lot of positional parameters which make it hard to read.

Will this have a backwards-incompatibility problem? If someone has existing subclasses of AMP_Base_Embed_Handler with register_embed defined, should it not do something like this:

Suggested change

if ( $embed_handler instanceof Registerable ) {

if ( $embed_handler instanceof Registerable || method_exists( $embed_handler, 'register_embed' ) ) {

This property can be marked as @deprecated and any usages in the subclasses can be eliminated (all of which are write-only currently), as it is not serving any purpose anymore.

In the past it was used to determine whether or not the AMP component script needed to be added to the page. But this is obsolete.

If not implemented? Doesn't an abstract method always have to be implemented by a subclass? Shouldn't this method just be changed to be non-abstract and then return null here? Then only the subclassed methods would return DOMNodeList. This would avoid needing to define the method to return null as it stands today for Twitter, Playlist, Gallery, and Blocks.

As discussed over chat, let's pause work on this until after beta1 or else 1.7 worst case. This will allow us to focus on the RME issues.
