BU Blocks is a WordPress plugin that registers additional blocks for the new WordPress editor.

Description

BU Blocks provides content editors with additional blocks for the new WordPress editor. These blocks were built for various sites within the BU WordPress ecosystem and have been tested and designed to be re-used for any project.

How to run Visual Regression Testing

To make testing changes to this plugin easier, you may wish to test your sandbox against an existing website. This is possible to do using wp-cli and the bu-webdiff library, which allows you to pull a list of URLs to test, and then test the differences locally in npm. This is just like you do during a WordPress upgrade.

For example, let's say I cloned the BU Blocks demo site to my sandbox. Here, I am grabbing a list of all the pages that are on that demo site in my sandbox.

wp post list --post_type=page --url=https://id-ashley.cms-devl.bu.edu/bu-blocks/ --fields=url --format=csv

From here, you could copy and paste the URLs into a text file and use the npm instructions to run visual regression testing locally.

You'll need to ssh into your sandbox to do this, just like if you were looking for PHP error logs.

Dependencies

• Gutenberg plugin 3.8
• WordPress 4.9.8 or later

Installation Instructions

1. Download this repository and either upload the zip file to the Add New plugin screen, or upload the contents of this repository to the /wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.

Resources

This plugin was built using a few open source plugin boilerplate examples:

• Create Guten Block -- A zero-configuration boilerplate for creating blocks for the new editor without having to configure webpack or babel.
  • Provides the base structure of this plugin.
  • Provides npm scripts that transpile ES6+/Next JavaScript into traditional ES2015 JavaScript that all modern browsers can understand.
  • Compiles all block sass to CSS.
  • Supplies the src/ directory where block development occurs.
  • Supplies the dist/ directory where the npm scripts distribute the final build files that get enqueued into the Editor and front-end.
  • Adds the hidden eslint config files.
• WP CLI wp scaffold plugin command -- The official WordPress plugin boilerplate.
  • Provides the initial package.json file for running Grunt tasks.
  • Adds two Grunt tasks for generating .pot file for translations and another task for converting the standard WordPress readme.txt file that is required for the official WordPress plugin repository to the more traditional README.md markdown format that Github can parse.
  • Adds the hidden .distignore, .gitignore, .editorconfig configuration files.
  • Adds .travis.yml, phpunit.xml.dist, and initial tests/ directory for continuous integration setup and PHPUnit testing.
  • Adds phpcs.xml.dist to define the WordPress Coding Standards this project follows.
• WordPress Plugin Boilerplate -- The unofficial plugin boilerplate code, with an opinionated object-oriented structure.
  • Although this plugin doesn't use a lot of the code, the project provides plugin organization principles that still apply for separating admin from public facing hooks.
  • Consolidates all hooks in one main plugin class, which helps maintainability. This logic exists in /src/init.php where define_admin_hooks() exists for consolidating all admin-specific hooks.
• BU Sample Plugin (feature/use_docker branch)
  • Adds the docker-compose.yml and the bin/wpdc.sh scripts for running the PHPUnit tests locally in an isolated docker container.
• WDS Blocks -- An open-source plugin by WebDevStudios for adding blocks to the new WordPress editor.
  • Borrows the autoloading strategy in src/init.php to help development focus on the creation of blocks rather than adding includes and requires for each block-specific PHP file that needs to be created.
  • Follows the same namespacing patterns for each PHP file so code is scoped to this plugin and avoids any conflicts with external dependencies that may have the same class names, function names, etc.

Create Guten Block

This project was bootstrapped with Create Guten Block.

Below you will find some information on how to run scripts.

You can find the most recent version of this guide here.

👉 npm start

• Use to compile and run the block in development mode.
• Watches for any changes and reports back any errors in your code.

👉 npm run build

• Use to build production code for your block inside dist folder.
• Runs once and reports back the gzip file sizes of the produced code.

👉 npm run eject

• Use to eject your plugin out of create-guten-block.
• Provides all the configurations so you can customize the project as you want.
• It's a one-way street, eject and you have to maintain everything yourself.
• You don't normally have to eject a project because by ejecting you lose the connection with create-guten-block and from there onwards you have to update and maintain all the dependencies on your own.

Running PHPUnit tests locally in docker

Requirements

Running tests locally in docker requires docker and docker-compose to be installed in your machine.

You can download it here https://www.docker.com/community-edition#/download.

Note: docker-compose comes with Docker for Mac and Docker for Windows. On linux you need to install docker-compose separately.

Steps

1. Go to the plugin/theme directory.

   cd /path/to/plugin
   

2. Run the wpdc up command to initialize and setup docker containers.

   bash bin/wpdc.sh up
   

3. Run the wpdc test command to run phpunit (as long as the containers are running, you can edit your files and run this command as many times as you want).

   bash bin/wpdc.sh test
   

4. Run the wpdc down command to stop and remove containers when you are done testing.

   bash bin/wpdc.sh down
   

Docker commands in bin/wpdc.sh script

up

Starts docker containers and sets up WordPress testing environment so that we can use the test command. Usage

bash bin/wpdc.sh up [php-version] [wp-version]

It takes 2 optional arguments:

1. [php-version]

   The php version we want to test. Normally a 2 digit version like 5.6, 7.0, 7.1. It defaults to latest (which at the moment resolves to 7.1 but can change in the future).

2. [wp-version]

   The WordPress version we want to test. It can be a 1, 2 or 3 digit version like: 4, 4.9, 4.7.3. It defaults to latest.

Examples

bash bin/wpdc.sh up
bash bin/wpdc.sh up latest
bash bin/wpdc.sh up latest latest
bash bin/wpdc.sh up 7.0
bash bin/wpdc.sh up 7.0 latest
bash bin/wpdc.sh up latest 4.6
bash bin/wpdc.sh up 7.1-apache 4.7
bash bin/wpdc.sh up latest 4.8
bash bin/wpdc.sh up 5.6 4.3

down

Stops and removes everything created with the up command. Usage

bash bin/wpdc.sh down

It takes no arguments.

test

Runs the phpunit tests inside the docker container. Usage

bash bin/wpdc.sh test

It takes no arguments.
