wp-​Typography API

While wp-​Typography is set up to pro­vide the best pos­si­ble ex­pe­ri­ence “out of the box”, Word­Press is an open sys­tem and some­times, as a theme or plu­g­in de­vel­op­er, you need to fine-​tune the re­sults. To this end, wp-​Typography pro­vides sev­er­al func­tions and fil­ter hooks.

In­tro­duc­tion

Al­though wp-​Typography in­cludes a va­ri­ety of fil­ters to make your web­page look good, it may be nec­es­sary to add fil­ters to ar­eas not cov­ered by the de­faults. In or­der to do this, you cur­rent­ly have use code sim­i­lar to this:

add_filter('some_custom_hook', [ 'WP_Typography', 'process' ] ); 
If you don't want to apply the full list of typographic adjustments (most notably hyphenation), but want to get smart quotes and characters, you can use the filter_feed method instead.
add_filter('some_custom_hook', [ 'WP_Typography', 'process_feed' ] ); 
Sometimes, you may like to apply slightly different settings to a particular string. You can do that as well. In this example, only really long words should be hyphenated:
$s = WP_Typography::get_user_settings();
$s->set_min_length_hyphenation( 10 );

$hyphenated_title = WP_Typography::process_title( $title_with_big_words, $s );
Note
Prior to wp-Typography 5.3.0, WP_Typography::process et al. could only be called on the object returned by WP_Typography::get_instance() and for static calls their WP_Typography::filter aliases had to be used. These aliases have been deprecated as of 5.3.0 and will be removed entirely with the release of wp-Typography 6.0.0.
