/**
|

|
|
* Presets are a set of values that serve
|
||
|
|
* to bootstrap some styles: colors, font sizes, etc.
|
||
|
|
*
|
||
|
|
* They are a unkeyed array of values such as:
|
||
|
|
*
|
||
|
|
* array(
|
||
|
|
* array(
|
||
|
|
* 'slug' => 'unique-name-within-the-set',
|
||
|
|
* 'name' => 'Name for the UI',
|
||
|
|
* <value_key> => 'value'
|
||
|
|
* ),
|
||
|
|
* )
|
||
|
|
*
|
||
|
|
* This contains the necessary metadata to process them:
|
||
|
|
*
|
||
|
|
* - path => Where to find the preset within the settings section.
|
||
|
|
* - prevent_override => Disables override of default presets by theme presets.
|
||
|
|
* The relationship between whether to override the defaults
|
||
|
|
* and whether the defaults are enabled is inverse:
|
||
|
|
* - If defaults are enabled => theme presets should not be overridden
|
||
|
|
* - If defaults are disabled => theme presets should be overridden
|
||
|
|
* For example, a theme sets defaultPalette to false,
|
||
|
|
* making the default palette hidden from the user.
|
||
|
|
* In that case, we want all the theme presets to be present,
|
||
|
|
* so they should override the defaults by setting this false.
|
||
|
|
* - use_default_names => whether to use the default names
|
||
|
|
* - value_key => the key that represents the value
|
||
|
|
* - value_func => optionally, instead of value_key, a function to generate
|
||
|
|
* the value that takes a preset as an argument
|
||
|
|
* (either value_key or value_func should be present)
|
||
|
|
* - css_vars => template string to use in generating the CSS Custom Property.
|
||
|
|
* Example output: "--wp--preset--duotone--blue: <value>" will generate as many CSS Custom Properties as presets defined
|
||
|
|
* substituting the $slug for the slug's value for each preset value.
|
||
|
|
* - classes => array containing a structure with the classes to
|
||
|
|
* generate for the presets, where for each array item
|
||
|
|
* the key is the class name and the value the property name.
|
||
|
|
* The "$slug" substring will be replaced by the slug of each preset.
|
||
|
|
* For example:
|
||
|
|
* 'classes' => array(
|
||
|
|
* '.has-$slug-color' => 'color',
|
||
|
|
* '.has-$slug-background-color' => 'background-color',
|
||
|
|
* '.has-$slug-border-color' => 'border-color',
|
||
|
|
* )
|
||
|
|
* - properties => array of CSS properties to be used by kses to
|
||
|
|
* validate the content of each preset
|
||
|
|
* by means of the remove_insecure_properties method.
|
||
|
|
*
|
||
|
|
* @since 5.8.0
|
||
|
|
* @since 5.9.0 Added the `color.duotone` and `typography.fontFamilies` presets,
|
||
|
|
* `use_default_names` preset key, and simplified the metadata structure.
|
||
|
|
* @since 6.0.0 Replaced `override` with `prevent_override` and updated the
|
||
|
|
* `prevent_override` value for `color.duotone` to use `color.defaultDuotone`.
|
||
|
|
* @since 6.2.0 Added 'shadow' presets.
|
||
|
|
* @since 6.3.0 Replaced value_func for duotone with `null`. Custom properties are handled by class-wp-duotone.php.
