Preferred Languages: Help test the latest version

Since the last update on the Preferred Languages feature plugin, a lot of work has been accomplished both on the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

Today, I want to provide a bit more details on these accomplishments, which resulted in the recent release of Preferred Languages 2.0, advancing the project a huge step closer towards a core merge proposal

But first, make sure to check out the previous update:

Improved Stability, Fully Rewritten

Over the last year, a lot of work has gone into making the plugin more stable by adding more tests and fixing bugs. This includes improving compatibility with other plugins and making translationtranslation The process (or result) of changing text, words, and display formatting to support another language.

As a result, pure unit testunit test Code written to test a small piece of code or functionality within a larger application. Everything from themes to WordPress core have a series of unit tests.

Often an acquired skill. improvements in WordPress 6.1 and 6.2, the Preferred Languages plugin is now fully compatible with WP_Textdomain_Registry and switch_to_user_locale(). The minimum required WordPress version has been bumped to 6.1 as a result.

Certainly the biggest change, however, was the full refactoring of the UIUI User interface itself.

The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers).

How to help

So, what’s next? The latest version of the Preferred Languages feature pluginFeature Plugin A plugin that was created with the intention of eventually being proposed for inclusion in WordPress Core. See Features as Plugins. needs more eyes testing it and providing feedback.

One big remaining question mark is the concept of translation merging. By default, if there are only some missing strings in a selected locale, these would be displayed in English. But with translation merging, the missing strings will be taken from the locale next in line instead. While this works great, it could be a tad slow due to the way translations are loaded in WordPress. Any help addressing this potential performance concern would be greatly appreciated.

Note: The merging feature can be enabled with add_filter( 'preferred_languages_merge_translations', '__return_true' );.
