Plugin: Use bundled files for enqueuing global styles by Mamaduka · Pull Request #50310 · WordPress/gutenberg

Mamaduka · 2023-05-04T08:38:26Z

What?

PR adds a script loader not tied to the specific WP version to override global styles enqueued by core. The new one will use the WP_Theme_JSON classes bundled with the plugin.

Why?

Bundled WP_Theme_JSON files should provide some of the settings for global styles.

How?

Hey, @oandregal

What do you think about these "permanent" overrides for settings that need to use bundled WP_Theme_JSON_*Gutenberg classes?

tellthemachines

Thanks for getting this started! It not working for me yet with the testing steps I outlined in the other PR, but I think this is a good approach in general, at least while global styles and design tools are still under active development.

Mamaduka · 2023-05-05T05:19:11Z

@tellthemachines, I think I got all the parts ported into the new system. Overriding the styles for block editor settings was the missing piece - eec751a.

Yeah, this is annoying. As long as the underlying classes receive changes, the public API needs to point at them in the plugin.

I'd think it's best to make them "evergreen" (so they'd sit in lib/) as the private classes do. I wouldn't be against making them part of lib/compat/6.X, though it seems that this would just "move the problem to the future": once the minimum WP version for Gutenberg is 6.2 they'll be removed, so we'll run into the same issue because the private classes will still receive updates. Does that sound sensible?

Mamaduka · 2023-05-05T07:44:21Z

I wouldn't be against making them part of lib/compat/6.X, though it seems that this would just "move the problem to the future"

I agree. Keeping this code in compat/wordpress- creates an "opportunity" for future regressions.

One more thing. Should I also move _gutenberg_clean_theme_json_caches into the "evergreen" files, or is there a plan to match the cache keys used by the plugin to WP?

No, they need to be different from core.

Would you be up to prepare small PRs that migrate each method separately? Otherwise, it's a big PR with a lot of changes that are difficult to match to each other. If it's just moving methods around, things are easy to spot.

Mamaduka · 2023-05-05T08:06:24Z

Would you be up to prepare small PRs that migrate each method separately?

I would, but all the changes in this PR are needed to fix the regression reported by @tellthemachines - #50079 (comment).

I've not touched the methods; I just moved them. The changes that could use a detailed review are concentrated in lib/block-editor-settings.php and lib/script-loader.php files.

oandregal · 2023-05-05T08:46:56Z

-
-	/*
-	 * For the remaining types (presets, styles), we do consider origins:
+if ( ! function_exists( 'wp_get_global_styles_custom_css' ) ) {


I was expecting that the only change here would be to move some methods from this file to lib/get-global-styles-and-settings.php.

As far as I've checked, we should move gutenberg_get_global_styles_custom_css, gutenberg_get_global_stylesheet, gutenberg_get_global_settings, _gutenberg_clean_theme_json_caches, _gutenberg_add_non_persistent_theme_json_cache_group.

I moved everything besides _gutenberg_add_non_persistent_theme_json_cache_group. The cache group would be the same, so there's no need to keep that function after 6.2.

Mamaduka · 2023-05-09T16:52:30Z

@oandregal, I addressed the feedback, and PR is ready for another review.

Hi, @tellthemachines

Did you get a chance to test the fix?

tellthemachines · 2023-05-10T07:03:20Z

@Mamaduka I won't be able to do a full code review this week, but I've just tested the latest state of this branch and it's now working correctly. I checked the spacing styles within flow/constrained layouts and also the experimental grid styles, and both are as expected ✅

Mamaduka · 2023-05-10T07:08:35Z

I won't be able to do a full code review this week,

Not a problem. I just want to be sure that PR fixes the regression. Thanks for testing!

aaronrobertshaw

Thanks for addressing this @Mamaduka 👍

It's always a pleasure to find a bug already has a fix up for review!

It turns out #50079 also caused the custom selectors API to be missed. This PR fixes that issue.

The code changes LGTM but it might be best to wait on a final review from @tellthemachines to make sure everything has been covered from their end.

This brings back a function that I haven't seen at #50079 though it still makes sense to me.

oandregal

I haven't tested this solves the issues brought by others. The code changes make sense to me: either move things around or add back things (added comments for each function trying to document what changes).

Mamaduka · 2023-05-11T16:25:10Z

Thanks, @oandregal!

I’ll merge this to fix the regressions. Happy to follow up in case I missed something.

Mamaduka · 2023-05-12T06:35:59Z

@fabiankaegy, the #50079 will ship with Gutenberg 15.8; I think it makes sense to cherry-pick this PR and avoid regressions in the release.

fabiankaegy · 2023-05-12T06:52:06Z

I just cherry-picked this PR to the release/15.8 branch to get it included in the next release: f7d2fbd

* Plugin: Use bundled files for enqueuing global styles * Override the '__experimentalFeatures' * Recreate global styles for block editors * Move global styles custom CSS handlers * Move _gutenberg_clean_theme_json_caches * Override global styles custom CSS properties

oandregal · 2023-05-12T14:38:07Z

I've got a couple of follow-ups at #50596 and #50597.

It seems this broke duotone filters which rely on updating $settings['styles'] in the same hook. Is there a reason that this hook needs to run at PHP_INT_MAX priority?

Is there a reason that this hook needs to run at PHP_INT_MAX priority?

That's what the plugin always used for block setting overrides. I guess to prevent other plugins from overriding new feature settings.

I personally don't like the use of PHP_INT_MAX; it prevents extensibility.

Can you point me to where the Duotone filters are located? Happy to help with the fix.

That's what the plugin always used for block setting overrides.

Ah, it just appended to the styles rather than replacing them before.

Can you point me to where the Duotone filters are located?

The duotone hook is here

gutenberg/lib/block-supports/duotone.php

Line 54 in b057776

add_filter( 'block_editor_settings_all', array( 'WP_Duotone_Gutenberg', 'add_editor_settings' ), 10 );

Happy to help with the fix.

Thanks! I'll probably push up a PR sometime today and add you as a reviewer. It sounds like it should be safe to lower the priority to allow for the extensibility that now comes from within the plugin.

@oandregal, any thoughts on lowering the priority for the plugin overrides?

Opened #50760. I found and fixed a few other things when I was digging through all of the code that used the same hook.
