Merge Proposal: Preferred Languages

Almost 8 years ago the Preferred Languages feature project was kicked off in response to a feature requestfeature request A feature request should generally begin the process in the ideas forum, on a mailing list, as a plugin, or brought to the attention of the core team, such as through scope meetings held for each major release. Unsolicited tickets of this variety are typically, therefore, discouraged. in #28197. Right now it is probably the oldest active feature pluginFeature Plugin A plugin that was created with the intention of eventually being proposed for inclusion in WordPress Core. See Features as Plugins.. Over time there were numerous updates, bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. fixes, and even a complete refactor. Preferred Languages was always built and maintained with the goal in mind to merge it into coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. one day. Now the time is finally right to do so.

Purpose & Goals

As a quick reminder, Preferred Languages replaces the existing languages dropdown with a supercharged version that lets you select multiple preferred languages. WordPress then tries to load the translations for the first language that’s available, falling back to the next language in your list otherwise. Without this, WordPress would just fall back to English (US) in such cases, which is not a great experience. Such a UIUI User interface is a pretty standard feature that can be seen for example also in operating system and browser settings.

Example of the Preferred Languages UI on the settings page

Note: Preferred Languages works for both the site language (can be set at Settings -> General) and the user language (can be set in the profile).

Project Background

You may wonder why it took such a long time. Since the project’s inception, a lot has changed in WordPress. For example, GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ happened. That’s why Preferred Languages saw a complete rewrite using the same ReactReact React is a JavaScript library that makes it easy to reason about, construct, and maintain stateless and stateful user interfaces. https://reactjs.org/. components that also power the blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. editor. With Gutenberg we also saw the introduction of JavaScript localization, which required further iterations to Preferred Languages. Then there was a need for merging incomplete translations, reducing the chances that you see missing strings in English. However, merging translations was very bad for performance, as it involves loading lots of translationtranslation The process (or result) of changing text, words, and display formatting to support another language. Also see localization, internationalization. files. In WordPress 6.5 we finally completely replaced the localization library with a more performant solution that natively supports loading multiple files at once. So this last remaining blockerblocker A bug which is so severe that it blocks a release. is now finally resolved!

Internationalization and localization is a core part of WordPress and relevant for more than half of all users. That’s why this functionality belongs natively into WordPress core and not in a (canonical) plugin. Merging Preferred Languages into core would allow the fallback logic to run much closer to where translation loading happens, reducing the risk for bugs and pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party incompatibilities. Plus, the UI impact is minimal, as it simply expands an existing language dropdown with additional features.

Implementation Details

The UI is built using TypeScript and React and the @wordpress/* npm packages also used for Gutenberg. This makes for a consistent look & feel and will make it easy to integrate it into any revamped WordPress adminadmin (and super admin) UI. The back end parts were developed in such a way that merging them into core eventually is as straightforward as possible, so a patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing. can be developed relatively quickly.

It works in all major browsers supported by WordPress, follows accessibilityAccessibility Accessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities.

Merge Announcement: Interactivity API

View the kickoff post, the status update post, and the Trac ticket for the Interactivity APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways..

Purpose & Goals

Currently, pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party authors implement their chosen JavaScriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. frameworks (or vanilla JSJS JavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors.) to enhance user experiences on WordPress sites. There is no consistency or standardized pattern for developing frontend JavaScript in WordPress.

The Interactivity API provides a standard way for developers to add interactions into the frontend of their blocks.

The API has been designed and created with these requirements:

  • BlockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience.-first and PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher-first. Prioritizing blocks for building sites and server side rendering for better SEO and performance. Combining the best for user and developer experience.
  • Backward compatible. Ensuring compatibility with both classic and block themes and optionally with other JavaScript frameworks, though it’s advised to use the API as the primary method. It also works with hooksHooks In WordPress theme and development, hooks are functions that can be applied to an action or a Filter in WordPress. Actions are functions performed when a certain event occurs in WordPress. Filters allow you to modify certain functions. Arguments used to hook both filters and actions look the same. and internationalization.
  • Declarative and reactive. Utilizing declarative code to define interactions, listening for changes in data, and updating only relevant parts of the DOM accordingly.
  • Performant: Optimizing runtime performance to deliver a fast and lightweight user experience.
  • Send less JavaScript. Reduce the overall amount of JS being sent on the page by providing a common framework that blocks can reuse.  So the more that blocks leverage the Interactivity API, the less JS will be sent overall.

A live demo of what can be achieved was announced in the State of the WordState of the Word This is the annual report given by Matt Mullenweg, founder of WordPress at WordCamp US. It looks at what we’ve done, what we’re doing, and the future of WordPress. https://wordpress.tv/tag/state-of-the-word/..

Live site demo

In case you want to read more about the goals, you can refer to the initial proposal.

Project Background

The project started as an experimental plugin in early 2022. Then, the first API version debuted in Gutenberg 16.2 and has been continually refined until Gutenberg 17.7.

In WordPress 6.4,the Image, Search, File, Navigation, and Query coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. blocks were refactored using the private version of the Interactivity API, addressing accessibilityAccessibility Accessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. 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). (https://en.wikipedia.org/wiki/Accessibility) issues and adding the long-time expected lightbox (or “expand on click”) feature for images.

The development has been done in GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/, using a Tracking Issue to monitor progress and a Discussions category to solicit feedback and offer guidance to developers who assisted in testing.

Implementation Details

The Interactivity API is a standard system of directives, based on declarative code, for adding frontend interactivity to blocks.

Directives are special HTMLHTML HyperText Markup Language. The semantic scripting language primarily used for outputting content in web browsers. attributes that tell the Interactivity API to attach a specified interaction to a DOM element or to transform it, similar to HTMX or AlpineJS. Using HTML as the templating language enables the API to understand the directives both in the server (PHP) and in the client (JS).

As part of this project, and all the interactivity scripts are now implemented leveraging the new script modules which are also shipping in WordPress 6.5. All of them will only be loaded on the frontend if at least one interactive block is present, to avoid sending unnecessary JavaScript to the frontend.

Here is an example of an interactive block, with a JavaScript file in charge of increasing or decreasing a counter, and a PHP file in charge of counter initialization and rendering.

// JS File - viewScriptModule.js

import { store } from "@wordpress/interactivity";

const { state } = store("my-counter-block", {
 actions: {
   increaseCounter: () => {
     state.counter = state.counter + 1;
   },
   decreaseCounter: () => {
     state.counter = state.counter - 1;
   },
 },
});

// PHP File - render.php
wp_interactivity_state('my-counter-block', array(
   'counter' => 0,
))
?>

<div
   <?php echo get_block_wrapper_attributes(); ?>
   data-wp-interactive="create-block"
>
   <button data-wp-on--click="actions.increaseCounter">
       <?php esc_html_e( 'Increase', 'my-first-interactive-block' ); ?>
   </button>
   <p data-wp-text="state.counter"></p>
   <button data-wp-on--click="actions.decreaseCounter">
       <?php esc_html_e( 'Decrease', 'my-first-interactive-block' ); ?>
   </button>
</div>

This would result in a block like this one:

For developers looking to get started, there is a Getting Started guide available, with plans to transition it to a handbook in the near future.

Additionally, a detailed dev notedev note Each important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. will be released, providing further insights into utilizing the API and understanding its internal workings.

Modules and Import maps.

The Interactivity API brings along the support of Modules and Import Maps.

JavaScript modules have transformed the way developers write and organize JavaScript code. They provide a cleaner and more modular architecture, making code easier to maintain, test and reuse across projects.

With the addition of native support for registering and enqueueing JavaScript modules, WordPress can keep pace with web development by using efficient, effective and battle-tested methods to handle JavaScript libraries and their dependencies.

There will be another dev note about JavaScript Modules and a guide to use them.

Guide to Javascript Modules.

Contributions and Feedback.

The Interactivity API is intended to be a long-term project with future enhancements; feedback is highly welcome. The best way to reach out is via GitHub Discussions.

Code and documentation contributions are also welcomed, and the Gutenberg repository is the place to go.

Some examples of contributing could be:

  • Test the Interactivity API, create your own interactions, and share feedback about what you like and you don’t.
  • Suggest new features to include in the API.
  • Help creating tutorials or share demos that can inspire other people.

Spread the word

The more developers who use Interactivity API in their projects, the more consistency there will be in the WordPress ecosystem, and the less JavaScript will be sent to the world!

Feel free to spread the word about the Interactivity API in social media and events with your colleagues, friends, and everyone!

Props to @cbringmann, @gziolo, @swissspidy, @westonruter, @santosguillamot, @luisherranz, and @rmartinezduque for peer review.

Merge Announcement: Plugin Dependencies

Note: This post was updated to add the “Third-party plugins not hosted on WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/” section. 15th February, 2024 – @costdev

View the kickoff post, the Trac ticket and the feature plugin for PluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party Dependencies.

Purpose & Goals

Extensibility of WordPress through plugins and the HooksHooks In WordPress theme and development, hooks are functions that can be applied to an action or a Filter in WordPress. Actions are functions performed when a certain event occurs in WordPress. Filters allow you to modify certain functions. Arguments used to hook both filters and actions look the same. APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. is one of its most beneficial features. There are many plugins that act purely as extensions of others, building functionality on top. The Plugin Dependencies feature aims to make the process of installing/activating addons (dependents) and the plugins they rely on (dependencies) consistent and easy to use.

Plugin authors are currently implementing their own ways of informing users about other plugins that they depend on. The implementations are inconsistent and sometimes incomplete. Users are often left to search for and install the other required plugins themselves.

The feature does not intend to replace the need for defensive coding within dependent plugins, or ensure version compatibility with their dependencies; nor does it seek to mitigate the vast array of potential plugin interactions. For WordPress and/or PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher incompatibilities, CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. already has handling for preventing installing, updating, or activating plugins with unmet requirements.

Implementation Details

A plugin’s dependencies can be declared by the use of a new Requires Plugins headerHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes. in the dependent plugin’s main file. This must contain a comma-separated list of WordPress.org slugs for its dependencies, such as jetpack (jetpack/jetpack.php is not supported). It does not support commas in plugin slugs.

Example

/**
 * Plugin Name: Bridge for Foo and Bar
 * Requires Plugins: foo, bar
 */

Version management support, such as providing specific minimum and maximum version numbers through the Requires Plugins header value, is not currently supported.

Requirements

Declaring a plugin dependency places the following requirements:

  1. Bridge for Foo and Bar can only be installed once Foo and Bar have been installed.
  2. Bridge for Foo and Bar can only be activated once Foo and Bar have been activated.
  3. Foo and Bar can only be deactivated once Bridge for Foo and Bar has been deactivated.
  4. Foo and Bar can only be deleted once Bridge for Foo and Bar has been deleted.

Viewing, installing and activating dependencies

In the Plugins > Add New screen, dependencies are listed in the dependent’s plugin card. Next to these is a View Details link to open a dependency’s information modal. The dependency can be installed and activated using the buttons in the modal’s footer.

Previously, the modal would close upon clicking the Install Now or Activate button. The feature makes the modal persistent, and the buttons used in the plugin cards and modal now use the same underlying markup and functionality for consistency and reduced maintenance burden.

The side effect of this shared functionality is that automatic redirection upon activating a plugin from Plugins > Add New is no longer available. This has the benefit of not redirecting a user away from the Plugins > Add New screen for each plugin, removing them from their current context. Users can therefore install and activate multiple plugins without leaving their current context.

For plugins with onboarding experiences, they often have additional logic in case a plugin is installed and activated through a tool such as WP-CLIWP-CLI WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is http://wp-cli.org/ https://make.wordpress.org/cli/, so that the user is still presented with the onboarding experience upon navigating to a screen deemed an appropriate starting place.

Automatic deactivation of dependent plugins

As currently implemented, plugins with unmet dependencies are automatically deactivated. While this was the approach suggested in initial discussions, there were valid concerns raised about this behavior after merging into trunk. These have been weighed and discussed, and a decision was made to remove this behavior.

Third-party plugins not hosted on WordPress.org

Defining plugins not hosted on WordPress.org as dependencies will enforce and display the dependencies to the user. However, there will be no ability to install the missing plugins through the UIUI User interface changes, and these will need to be installed manually.

UI changes

The feature makes changes to the UI on two screens: Plugins > Installed plugins, and Plugins > Add New.

Design Feedback

Design feedback was requested on the ticketticket Created for both bug reports and feature development on the bug tracker. and responses were received from @azaozz, @paaljoachim and @karmatosed on the ticket and on the Feature Plugin repository.

Plugins > Installed plugins

The following changes are made:

  1. Dependent plugin rows now contain a list of their dependencies, linked to the respective plugin modal to install and activate the dependency.
  2. Dependency plugin rows now contain a list of their dependents.
  3. If a plugin has dependencies that are not installed and active, the Activate link is disabled.
  4. If a plugin has dependents that are active, the Deactivate and Delete links are disabled.

Before

Plugin rows without listing any dependents or dependencies.
No dependents or dependencies are listed.

After

Plugin rows for a dependent and its two dependencies. The plugin row for a dependency shows a list of plugins that depend on it, and a dependent's plugin row shows a list of plugins that it depends on. The dependent's plugin row links the names of each dependency to a modal with buttons to install and activate the dependency.
Dependents and dependencies are listed, and actions are enabled/disabled based on the status of requirements.

Plugins > Add New

The following changes are made:

  1. If a plugin has unmet dependencies, the Install Now and Activate buttons are disabled, both in their plugin card and their plugin information modal.
  2. Dependent plugin cards now contain a notice listing their dependencies, with a View Details link to the dependency’s information modal which contains Install Now or Activate buttons based on their current installation status.
  3. Plugin information modals are now persistent after button clicks, and modal-based plugin installation and activation are now performed through AJAX directly within the modal.

Before

A plugin card that does not list dependencies for the plugin, and allows installation even if the dependencies are not installed first.
Plugin card with no dependencies listed and an active Install Now button despite unmet dependencies.

After

A plugin card with a notice containing a list of dependencies and a link to open a modal with buttons to install and activate the dependency
Plugin card with dependencies listed with modal links to install and activate each dependency, and the “Install Now” button disabled while dependencies are unmet.

User Testing

The feature team released calls for testing in October 2022 and March 2023. Additional user testing was performed during design and technical feedback with reports on the ticket and in the #core-upgrade-install SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. channel up to the day of commit.

Outcomes

Based on responses to calls for testing, and design and technical feedback, the following UI changes were made:

  1. Adminadmin (and super admin) notices for each unmet dependency were reduced to a single notice informing the user that there were plugins with unmet dependencies.
  2. A dedicated Dependencies tab was removed from the Plugins > Add New screen in favour of an integrated solution in plugin rows on Plugins > Installed plugins and plugin cards on Plugins > Add New.
  3. The plugin row on Plugins > Installed plugins had a Manage Dependencies action link removed, which linked to the removed Dependencies tab.
  4. Messaging was improved to inform the user about missing dependencies.

Security

A security review was performed by @costdev during the development of the feature following WordPress security best practices of escaping output, sanitizing input (slugs, POST, etc.), verifying AJAX referrers and using nonces where appropriate. Comparisons were also done with existing functionality to avoid missed opportunity for hardening the feature.

AccessibilityAccessibility Accessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. 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). (https://en.wikipedia.org/wiki/Accessibility)

The feature was reviewed by the team for accessibility concerns. In addition, @costdev reached out to @joedolson regarding the use of links (<a>) as buttons, rather than <button> elements.

It was deemed that this approach, though likely not ideal, is consistent with the patterns throughout the code base today. A wider conversation is needed before a decision can be made about this specific  accessibility pattern at a later date.

wp.a11y.speak() is implemented where appropriate in JavascriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/., consistent with prior functionality in Core.

Unit Tests

In addition to user testing, testing by Core developers, and the feature team, unit tests have been written for the feature and the public API is covered. There are plans to continue increasing test coverage during the 6.5 BetaBeta A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. period.

Fields API Chat Summary: September 13th, 2023

These are the notes from the first post-WCUS chat we had on Thursday, September 13th, 2023 at 12:00 PM CDT in the #core-fields channel of Make WordPress Slack.

Key Links

Proposed agenda items

A few agenda items were proposed in the channel by @alexstandiford including the following items. (Marked to show what we ended up getting through so far)

  1. ☑ Broadly speaking, what is the scope for V1?
  2. ☐ Can we define the independent pieces of this project? If not, what do we need to know in order to understand those pieces?
  3. ☐ Is it realistic to expect that we could split this project into smaller pieces, lead by groups of the contributors?
  4. ☐ How do we approach presenting this to coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.? How often to we provide updates?
  5. ☐ General discussion around the findings and conclusions surrounding the JSON fields API pitch. Could defining the JSONJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. help us understand the components that make the fields APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.?

What we talked about in the chat

We ended up spending over an hour discussing only that first item: What we as contributors think that V1 should and should not include. Feedback was varied so I gathered the list of things people came up with and turned that into a survey that contributors could vote on.

Survey: What to include in a V1 proposal

We also invite everyone in the community to provide feedback on what you think the V1 proposal for Fields API should include.

Fill out the survey to let us know what you’d like to see in a V1 of the Fields API

The survey will close on Wednesday, September 20th, 2023 at 12:00 PM (UTC-5) and we will share the results in the planned Fields API chat that day.

Remaining areas to research

We still have a few more screens to add research documentation for and those are these:

  • Users
    • User registration form
  • Media – Media modal
  • CustomizerCustomizer Tool built into WordPress core that hooks into most modern themes. You can use it to preview and modify many of your site’s appearance settings. API – @sc0ttkclark will take this on
  • Nav Menus (classic)
    • Name Menu form
    • Nav Menu Item form

If you’d like to help out, hop into #core-fields and or GitHub repository and let us know what area you’d like to contribute to.

Next scheduled chat

We will be meeting again in #core-fields on Wednesday, September 20th, 2023 at 12:00 PM (UTC-5)

See many of you then!

Call for Testing: Performant Translations

The coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. performance team recently conducted an in-depth i18n performance analysis. It showed that localized WordPress sites load significantly slower than a site without translations. The blogblog (versus network, site) post presented and compared multiple solutions to this problem, and now the team would like to test the most promising approach at a wider scale using a dedicated pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party.

Introducing the Performant Translations plugin

What it does

The Performant Translations plugin uses a new approach to handle translationtranslation The process (or result) of changing text, words, and display formatting to support another language. Also see localization, internationalization. files in WordPress, making localization blazing fast. The primary purpose of this plugin is to allow broader testing of these enhancements, for which the goal is to eventually land in WordPress core.

This plugin helps to make localized WordPress sites faster by replacing the traditional MO translation files with PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher files, which are much faster to parse. Plus, PHP files can be stored in the so-called OPcache, which provides an additional speed boost.

If your site is using a language other than English (US), you should see immediate speed improvements simply by activating this plugin. No further action is required.

The Performant Translations plugin is available for download on WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ or directly from your WordPress adminadmin (and super admin).

Download the plugin

What to test and expect

Since the Performant Translations plugin requires no configuration, all that’s needed to benefit from its speed improvements is to activate the plugin.

To verify that something has changed, you could use a tool like Query Monitor or an external tool for testing server response times. In Query Monitor, the page load time and memory usage should drop quite a bit after plugin activation:

Before: Page load time: 0.27s Memory usage: 32.9MB
Page load time and memory usage before
After: Page load time: 0.22s Memory usage: 20.2MB
Page load time and memory usage after

In Query Monitor you will also see how translations are loaded from PHP files from now on:

Query Monitor development tools, showing a list of text domains

While the plugin is mostly considered to be a betaBeta A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. testing plugin, it has been tested and established to a degree where it should be okay to use in production. Still, as with every plugin, you are doing so at your own risk.

It’s also worth noting that the plugin has been successfully tested with common multilingual plugins, such as WPML, Weglot, TranslatePress, MultilingualPress, and Polylang. It also works fine with Loco Translate and 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..

Should you choose to stop testing the Performant Translation plugins, uninstalling it will remove all of its traces.

Provide your feedback

If you encounter any issues or simply have questions about the plugin, please leave a comment below or open a new support topic. In addition to that, contributions can be made on GitHub.

The performance team’s goal is to get as much feedback as possible and further refine the approach so that it can ultimately be proposed to be merged into WordPress core 6.5. That means testing will last for a few months at least.

Fields API Progress Summary: WCUS Contributor Day 2023

We had a solid day of progress today at the WCUS Contributor DayContributor Day Contributor Days are standalone days, frequently held before or after WordCamps but they can also happen at any time. They are events where people get together to work on various areas of https://make.wordpress.org/ There are many teams that people can participate in, each with a different focus. https://2017.us.wordcamp.org/contributor-day/ https://make.wordpress.org/support/handbook/getting-started/getting-started-at-a-contributor-day/.. I sat down at an empty table and before long it was full of people who were eager to help bring the vision of the Fields APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. to fruition.

If you aren’t familiar yet with what we’ve been planning, check out the post below about the kick-off we had at the start of this year. Otherwise, continue on below to see what we’ve accomplished and what’s left in the Research phase.

Proposal draft work

We also had help from @lauriewood who spent time writing a proposal draft for us that we can use to build from with more technical details.

Comparison sheet

I put together a comparison sheet that goes over coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. APIs vs a few popular plugins. It may help you visualize what we are doing here.

What’s next?

Our next meeting

We’re going to set up another meeting in #core-fields on SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. in September to get everyone together again. I’ll post here again as soon as we have a time set so others who are interested can join.

Research will continue

We have a few more docs to continue working on. We will coordinate who does what in the #core-fields Slack channel. If you’re interested in helping, feel free to mention me (@sc0ttkclark) there!

Proposing the Fields API

We will then be able to officially propose the Fields API based on our research and gather feedback on what we’ve put together. The proposed code will likely remain similar to what was proposed in 2017 but with more modern PHPPHP The web scripting language in which WordPress is primarily architected.

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:

An Update on Preferred Languages

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. Also see localization, internationalization. merging and localeLocale A locale is a combination of language and regional dialect. Usually locales correspond to countries, as is the case with Portuguese (Portugal) and Portuguese (Brazil). Other examples of locales include Canadian English and U.S. English. switching more robust. 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. Also see regression. code coverage is near 100%, with end-to-end tests adding another layer of confidence.

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 whole JavaScriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers.

(https://en.wikipedia.org/wiki/Accessibility) has improved, but otherwise everything looks mostly the same.

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' );.

Active development is taking place on GitHub. If you want to get involved, check out the open issues and join the #core-i18n channel on Slack.

Fields API Kick-off Chat Summary: January 5th, 2023

It’s been over 4 years since the Fields API project has been active and many things have changed for WordPress in that period.

Since then, many things were introduced into WordPress itself including things like:

  • BlockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. Editor
  • Full Site Editing has replaced the CustomizerCustomizer Tool built into WordPress core that hooks into most modern themes. You can use it to preview and modify many of your site’s appearance settings. (which is now only used for classic themes)
  • New Navigation editing
  • Widgets are now legacy and have been replaced with new blocks and a new WidgetWidget A WordPress Widget is a small block that performs a specific function. You can add these widgets in sidebars also known as widget-ready areas on your web page. WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user. editor
  • Newer PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher compatibility (testing still in progress for PHP 8.0+) and talks of upping the minimum PHP version

All of that has led to @joedolson approaching me to determine if it’s worth bringing Fields APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. back with a new vision.

After some initial discussion, the passion reignited within me to get this going again and we ended up having our first kick-off meeting today to discuss where we’ve been, where we’re at, and where we want to go in 2023. This and future work will be organized through our SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. channel #core-fields

Read below for what we discussed and here’s a link to watch the video from our initial meeting.

    • Worked with WP for about 10 years
    • Not a developer but a user/self-titled user advocate
    • Coming at this as a perspective as a user who is interested in how this will work

Overview of Fields API – where we started

  • Started work in November 2013 with @ericlewis as lead and @sc0ttkclark as co-lead
  • Started holding meetings back when Freenode IRCIRC Internet Relay Chat, a network where users can have conversations online. IRC channels are used widely by open source projects, and by WordPress. The primary WordPress channels are #wordpress and #wordpress-dev, on irc.freenode.net. was being used before Slack
  • Initial focus was around Post metaMeta Meta is a term that refers to the inside workings of a group. For us, this is the team that works on internal WordPress sites like WordCamp Central and Make WordPress. fields and meta boxes in the Post Editor
  • Expanded over time to cover a generalized API to work with
    • Post meta boxes and their fields
    • Settings fields (replacing the Settings API)
    • User profile fields (edit profile, add new user)
    • Term fields (add term, edit term)
    • Comment fields (add comment on frontend, edit comment in dashboard)
    • Media fields (modal)
    • Customizer (allowing the Customizer to see Fields API configurations)
  • We built 3 different prototypes over time
  • Hundred of plugins in WP have their own Fields API and lots of devs have their own preference on code structure so there were lots of voices with different opinions for what the Fields API should look like
  • WP Core team (committers and contributors) were somewhat receptive but we couldn’t gain momentum
  • The block editor and other projects started up which reduced priority for getting Fields API into WP especially since it wasn’t just one small part of WP
  • @sc0ttkclark reached out for anyone else to take over the project as lead (while Scott supported) but couldn’t find anyone so the project became inactive

Rebooting Fields API – where we’re at

  • @joedolson approached @courane01 and @sc0ttkclark to see if we wanted to tackle Accessibility as a goal for a smaller reboot of the Fields API
  • The GitHub repository has been unarchived and is ready to start the next steps of getting things going again
  • Lots of test coverage for the API itself
  • A number of examples of how to work with the API
  • Implementations that were covered at the time (in WP 4.5)
  • Things that were in progress at the time (in WP 4.5)
  • @jason_the_adams gave a demo of the GiveWP Fields API
    • Uses a mid-level API to register the configurations
    • Implementations handle rendering those
    • The primary implementation is a Block Editor powered form editing experience
    • @borkweb and @sc0ttkclark provided positive feedback about the PHP side of things

Where we’re going

  • @sc0ttkclark What PHP version should we target?
    • PHP 5.6 is the current minimum and we’ll stick to that unless progress is made on upping the minimum WP version
    • If the minimum version is upped, we can revisit this and adjust our code to follow suit
  • @borkweb How we approach things in WP now is much different than back when the Fields API started
    • Is there merit in separation of data and output like what GiveWP is doing versus what the very coupled approach that the Fields API has right now
  • @joedolson Whether this can be potentially be used for the Block Editor may have a big impact on whether it has traction, though there are plenty places where it could be useful
  • @sc0ttkclark
    • Content areas like Posts and Terms, we’ll likely see more expansion of the Block Editor
    • There are a few places in WP that may not make sense to be in the block editor itself
      • Settings
      • User profile
      • Maybe others?
    • Those areas may eventually use ReactReact React is a JavaScript library that makes it easy to reason about, construct, and maintain stateless and stateful user interfaces. https://reactjs.org/. components to render but won’t live in the “Block Editor” that we know of today
    • We could separate the Fields API focus into specific component implementations, not unlike what we had before but with the goal being that we are registering structure – whether or not that is the same exact input used for each screen (some screens will need their own form implementations for their inputs that may not be HTMLHTML HyperText Markup Language. The semantic scripting language primarily used for outputting content in web browsers. renders)
    • If we wanted to implement Fields API for the Block Editor, it could help register Components for the Inspector Panel for Blocks, which is currently an area with high copy/paste
      • Fields API could register Inspector Panel sections and components
    • PHP has grown up and it may be better to use objects than straight PHP arrays especially since that can work with IDEs and help with autocomplete for a better developer experience
    • With the Fields API, I want to make possible the idea that you can interact with the configuration of a form and add/change fields by registering new fields or adjusting their configurations
    • Knowing what the structure of a page is (outside of just basic actions that people use now to render HTML) gives devs the ability to take those configurations and consume them through WP-CLIWP-CLI WP-CLI is the Command Line Interface for WordPress, used to do administrative and development tasks in a programmatic way. The project page is http://wp-cli.org/ https://make.wordpress.org/cli/, the REST APIREST API The REST API is an acronym for the RESTful Application Program Interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data. It is how the front end of an application (think “phone app” or “website”) can communicate with the data store (think “database” or “file system”) https://developer.wordpress.org/rest-api/., and PHP for custom implementations like the WordPress iOSiOS The operating system used on iPhones and iPads. app and many other apps that need to represent the various edit screens
  • @borkweb So the Fields API project would morph into a data layer and one or more rendering implementations to consume that
  • @sc0ttkclark
    • We can focus on Settings page at first and go from there into the User profile, but leave everything else out until we gain traction and get something into Core
    • Don’t focus on legacy things like the Classic Editor or Customizer or the Widget forms
  • @joedolson Getting this built out and implemented is a challenge but I’m game
  • @sc0ttkclark We should figure out what we want to structure the Fields API off of, but use object oriented as much as possible and make the focus on better developer experience so we can help level up working with WP
    • We could look at the structure of GiveWP’s Fields API and other modern Fields APIs from other plugins/libraries
    • Avoid looking back at older/legacy plugins and libraries
    • Find a consensus on what makes sense that most people will be familiar with based on what’s popular/modern
    • The current Fields API is based on the Customizer API which has become antiquated already

Next steps

  • Meetings: Figure out the frequency of meetings and when our next meeting is
  • Viability: Get a gut-check from WP core dev team in the core meeting and through responses to this post on direction and our focus
  • Spec: Look at modern Fields APIs in modern plugins/libraries and figure out how we want that structure to look like through a new spec doc
  • Code: Start with a Settings API implementation collaborating with @joedolson and the Accessibility team to ensure that side is accessible
  • Testing: Ensure the API is well tested with unit tests

Call for Testing: Plugin Dependencies

The Plugin Dependencies feature plugin is available for testing.

This feature allows pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party authors to identify which other plugins must be installed so that their plugin functions as expected. This is done by adding a “Requires Plugins” headerHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes. to the docblockdocblock (phpdoc, xref, inline docs) of the main plugin file which contains a comma-separated list of slugs for the required plugins.

The feature is not intended to work with Must-Use plugins, nor does it impact them.

You can find out more about this feature project in the original Make post.

Test Setup

  • Install and activate the Plugin Dependencies feature plugin.
  • Delete the Hello Dolly plugin, a single file plugin cannot be a dependency
  • Copy the three test plugin files from /plugins/wp-plugin-dependencies/test-plugins to the /plugins directory.
  • Navigate to Plugins > Installed Plugins.

Test Instructions / Key Features

  • Confirm that a new adminadmin (and super admin) notice is displayed if there are additional plugins that must be installed if dependencies are missing.
  • Confirm that individual plugins with dependency relationships on Plugins > Installed Plugins display Requires or Required by: under the version information.
  • Add (install/activate) needed dependencies.
  • Confirm that admin notice goes away once all the dependencies have been installed. Dependencies don’t need to be activated for the admin notice to be satisfied and go away.
  • After installing all dependencies, confirm that the new admin notice disappears.
  • Confirm that the Deactivate link and checkbox are not available for plugins that are dependencies with active dependent plugins.
  • Once all dependent plugins are deactivated, confirm that plugin dependencies can then be deactivated and deleted.
  • Confirm that the Add Plugins > Dependencies page lists correct plugins, including non-WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ plugins that are and aren’t supported.

Other Things to Test

  • In a test plugin, try to add a dependency using a plugin’s full name (not slug).
    • No dependency should be noted
  • Add a dependency for a non-wordpress.org plugin slug that is installed/active.
  • Hook the Plugins APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. to register a non-wordpress.org plugin.
    • This is done with the GitGit Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git is easy to learn and has a tiny footprint with lightning fast performance. Most modern plugin and theme development is being done with this version control system. https://git-scm.com/. Updater plugin
  • Test adding “Requires Plugins” to the DocBlock of a plugin in mu-plugins.
    • Nothing should happen as mu-plugins are not supported for this feature.

What’s New?

In the main plugin file’s docblock:

  • A Requires Plugins header has been introduced.
  • List the slugs of the dependencies in a comma separated string. For example:

Requires Plugins: hello-dolly, akismet, wp-plugin-dependencies

On the Plugins admin page:

  • An admin notice informs site owners if there are additional plugins that must be installed. It will display as long as there are uninstalled dependencies.
  • Each plugin that requires other plugins has a new line in the plugin description. For example:

Requires: <dependency-1>, <dependency-2>, <dependency-3>

Required plugins that are available on wordpress.org are linked to their plugin page.

  • Each plugin required by other plugins has a new line in the plugin description. For example:

Required by: <dependent-1>, <dependent-2>, <dependent-3>

  • Each plugin that is a dependency, and is also dependent on other plugins, has both lines above.
  • If all the dependencies of a plugin have not been installed and activated then the dependent plugin will not be able to be activated.
Plugins page

On the Plugins > Add New > Dependencies tab:

  • The above Requires and Required by data will display in the plugin card.
  • This tab shows a card for each plugin that is required for other plugins to work.
  • Familiar Install Now, Activate and Active buttons are provided so that site owners can manage these plugins.
  • If a dependency is not available on wordpress.org and does not integrate with the Plugin Dependencies feature, it will not be possible to install or activate via this tab. The plugin will display in a generic card.
  • It is possible to integrate a dependency that is not available on wordpress.org with the Plugin Dependencies feature. This requires hooking into the plugins_api_request filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. and returning a valid plugins_api() response.
