Allow all Gutenberg theme support options to be defined in theme.json

[kjellr]

Many of Gutenberg's add_theme_support() options are already available to define in experimental-theme.json:

• disable-custom-font-sizes
• disable-custom-colors
• disable-custom-gradients
• editor-color-palette
• editor-gradient-presets
• editor-font-sizes
• custom-line-height
• custom-units
• custom-spacing
• experimental-link-color

The rest should be made available there as well:

• align-wide
• core-block-patterns (opt-out)
• editor-styles
• dark-editor-style
• post-thumbnails
• responsive-embeds
• wp-block-styles

Some of these are already possible:

• disable-custom-font-sizes => settings.typography.customFontSize
• disable-custom-colors => settings.color.custom
• disable-custom-gradients => settings.color.customGradient

From the convo, I presume the list of missing options should also contain: align-wide, wp-block-styles.

[kjellr]

Thanks, I updated the list above. 👍

I wonder if for themes with theme.json "editor-styles", and "wp-block-styles" should be true by default. These are new themes being build and it seems like they should play well with all the styles a block contains.

I wonder if for themes with theme.json "editor-styles", and "wp-block-styles" should be true by default.

Yeah, I think that makes sense.

It would be nice to include add_theme_support('html5', ['script', 'style']);, as the type attribute is not required in HTML5 and currently enqueued files show them by default. Reference.

Does it make sense to have editor-styles on by default if the theme has no editor style file?

post-thumbnails The block works without theme support being enabled, but without the setting in the document sidebar. I wonder if this is already working as intended. (#22313)
It depends on how we want to convert existing featured images to blocks 🤔

+1 for alignement controls in theme.json (not only wide)

[devfle]

Do we need something like this the other way around? Things like the new border settings, or the margin feature can currently only be used by FSE themes.

[youknowriad]

core-block-patterns (opt-out)
editor-styles
post-thumbnails
responsive-embeds
wp-block-styles
html5

For what reasons these are disabled by default? I mean shouldn't we take the opportunity of FSE themes (or themes with theme.json) to enable these automatically? Does it still make sense for these to be configurable, should they be opt-in or opt-out.

[kjellr]

editor-styles
post-thumbnails
responsive-embeds
wp-block-styles
html5

Yeah, all of those seem like things we should enable by default for block themes.

[jasmussen]

Fairly sure that dark-editor-style has been absorbed and retired as a separate feature.

[noisysocks]

It seems then that the only action required here is to add a setting that equates to align-wide?

[carolinan]

Isn't align-wide the layout setting? If you do not include that in theme.json, the wide and full width is not enabled.

[youknowriad]

yes align-wide is kind of deprecated for block themes.

Let's close this for now.
