PHP task runner based on Robo, focused on extensibility.

Quick references:

• Installation
• Configuration
• Built-in commands
• Expose custom commands as YAML configuration
• Expose custom commands as PHP classes

Installation

Install it with Composer:

composer require openeuropa/task-runner

After installation run ./vendor/bin/run for a list of available commands.

Using Docker Compose

Alternatively, you can build a development site using Docker and Docker Compose with the provided configuration.

Docker provides the necessary services and tools to get the tests running, regardless of your local host configuration.

Requirements:

• Docker
• Docker Compose

Configuration

By default, Docker Compose reads two files, a docker-compose.yml and an optional docker-compose.override.yml file. By convention, the docker-compose.yml contains your base configuration and it's provided by default. The override file, as its name implies, can contain configuration overrides for existing services or entirely new services. If a service is defined in both files, Docker Compose merges the configurations.

Find more information on Docker Compose extension mechanism on the official Docker Compose documentation.

Usage

To start, run:

docker-compose up

It's advised to not daemonize docker-compose so you can turn it off (CTRL+C) quickly when you're done working. However, if you'd like to daemonize it, you have to add the flag -d:

docker-compose up -d

Then:

docker-compose exec web composer install

Running the tests

To run the grumphp checks:

docker-compose exec web ./vendor/bin/grumphp run

To run the phpunit tests:

docker-compose exec web ./vendor/bin/phpunit

Configuration

Task Runner provides a useful command (config) that allows inspecting and debugging the configuration. To find out how can be used, run:

./vendor/bin/run config --help

Task Runner commands can be customized in two ways:

1. By setting arguments and options when running a command.
2. By providing default values in configuration files. The task runner will read the following files in the specified order. Options supplied in later files will override earlier ones:
   • The defaults provided by Task Runner. This file is located inside the Task Runner repository in config/runner.yml.
   • runner.yml.dist - project specific defaults. This file should be placed in the root folder of the project that depends on the Task Runner. Use this file to declare default options which are expected to work with your application under regular circumstances. This file should be committed in the project.
   • Third parties might implement config providers to modify the config. A config provider is a class implementing the ConfigProviderInterface. Such a class should be placed under the TaskRunner\ConfigProviders relative namespace. For instance when Some\Namespace points to src/ directory, then the config provider class should be placed under the src/TaskRunner/ConfigProviders directory and will have the namespace set to Some\Namespace\TaskRunner\ConfigProviders. The class name should end with the ConfigProvider suffix. Use the ::provide() method to alter the configuration object. A @priority annotation tag can be defined in the class docblock in order to determine the order in which the config providers are running. If omitted, @priority 0 is assumed. This mechanism allows also to insert custom YAML config files in the flow, see the following example:

     namespace Some\Namespace\TaskRunner\ConfigProviders;
     
     use OpenEuropa\TaskRunner\Contract\ConfigProviderInterface;
     use OpenEuropa\TaskRunner\Traits\ConfigFromFilesTrait;
     use Robo\Config\Config;
     
     /**
      * @priority 100
      */
     class AddCustomFileConfigProvider implements ConfigProviderInterface
     {
         use ConfigFromFilesTrait;
         public static function provide(Config $config): void
         {
             // Load the configuration from custom.yml and custom2.yml and
             // apply it to the configuration object. This will override config
             // from runner.yml.dist (which has priority 1500) but get
             // overridden by the config from runner.yml (priority -1000).
             static::importFromFiles($config, [
                 'custom.yml',
                 'custom2.yml',
             ]);
         }
     }
     

   • runner.yml - project specific user overrides. This file is also located in the root folder of the project that depends on the Task Runner. This file can be used to override options with values that are specific to the user's local environment. It is considered good practice to add this file to .gitignore to prevent runner.yml from being accidentally committed in the project repository.
   • User provided global overrides stored in environment variables. These can be used to define environment specific configuration that applies to all projects that use the Task Runner, such as database credentials and the Github access token. The following locations will be checked and the first one that is found will be used:
     • $OPENEUROPA_TASKRUNNER_CONFIG
     • $XDG_CONFIG_HOME/openeuropa/taskrunner/runner.yml
     • $HOME/.config/openeuropa/taskrunner/runner.yml

• Installation

A list of default values, with a brief explanation, can be found at the default runner.yml.

Built-in commands

The Task Runner comes with the following built-in commands:

Run ./vendor/bin/run help [command-name] for more information about each command's capabilities.

Expose "dynamic" commands as YAML configuration

The Task Runner allows you to expose new commands by just listing its tasks under the commands: property in runner.yml.dist/runner.yml.

For example, the following YAML portion will expose two dynamic commands, drupal:site-setup and setup:behat:

commands:
  drupal:site-setup:
    - { task: "chmod", file: "${drupal.root}/sites", permissions: 0774, recursive: true }
    - { task: "symlink", from: "../../custom/modules", to: "${drupal.root}/modules/custom" }
    - { task: "symlink", from: "../../custom/themes", to: "${drupal.root}/themes/custom" }
    - { task: "run", command: "drupal:drush-setup" }
    - { task: "run", command: "drupal:settings-setup" }
    - { task: "run", command: "setup:behat" }
    - "./vendor/bin/drush --root=$(pwd)/${drupal.root} cr"
  setup:behat:
    - { task: "process", source: "behat.yml.dist", destination: "behat.yml" }

Commands can reference each-other, allowing for complex scenarios to be implemented with relative ease.

At the moment the following tasks are supported (optional argument default values in parenthesis):

Tasks provided as plain-text strings will be executed as is in the current working directory.

Expose custom commands as PHP classes

More complex commands can be provided by creating Task Runner command classes within your project's PSR-4 namespace.

For example, given you have the following PSR-4 namespace in your composer.json:

{
    "autoload": {
        "psr-4": {
            "My\\Project\\": "./src/"
        }
    }
}

Then you can expose extra commands by creating one or more classes under ./src/TaskRunner/Commands, as shown in the example below:

<?php

namespace My\Project\TaskRunner\Commands;

use OpenEuropa\TaskRunner\Commands\AbstractCommands;

/**
 * Class MyCustomCommands
 *
 * @package My\Project\TaskRunner\Commands
 */
class MyCustomCommands extends AbstractCommands
{
    /**
     * @command my-project:command-one
     */
    public function commandOne() { }

    /**
     * @command my-project:command-two
     */
    public function commandTwo() { }
}

After doing that remember to refresh your local autoloader by running composer dump-autoload.

You can now access your new commands via the Task Runner main executable:

$ ./vendor/bin/run
OpenEuropa Task Runner

Available commands:
 ...
 my-project
  my-project:command-four
  my-project:command-one

NOTE: It is mandatory to place your command classes under ./src/TaskRunner/Commands, otherwise the Task Runner will not register them at startup.

Even if not mandatory it is recommended for your command classes to extend OpenEuropa\TaskRunner\Commands\AbstractCommands.

For more details on how to expose custom commands please refer to the main Robo documentation.
