What does it do?

This Composer plugin displays a configurable message after Composer installation processes have finished.

This is ideal for a 'next steps' type prompt to help get the user oriented.

Currently only two Composer events are supported:

• post-create-project-cmd, when a composer create-project command has finished.
• post-install-cmd, when a composer install command has finished.

How do I set it up?

Require this Composer plugin in your project template composer.json file:

"require": {
  "drupal/core-project-message": "^8.8"
}

Configuration

There are three ways to configure this plugin to output information:

• Using a text file.
• Using composer.json schema keys.
• Embedding the information in the extra section of the composer.json file.

Using a text file

By default, the plugin will respond to post-install-cmd or post-create-project-cmd Composer events by looking for a similarly-named file in the root of the project. For instance, if the user issues a composer create-project command, when that command is finished, the plugin will look for a file named post-create-project-cmd-message.txt and then display it on the command line.

The file should be plain text, with markup suitable for Symfony's OutputInterface::writeln() method. See documentation here: https://symfony.com/doc/3.4/console/coloring.html

You can also configure your own file(s), using the extra section of your composer.json file:

"extra": {
  "drupal-core-project-message": {
    "post-create-project-cmd-file": "bespoke/special_file.txt"
  }
}

Using composer.json schema keys

You can tell the plugin to output the structured support information from the composer.json file by telling it the keys you wish to display.

Currently, only name, description, homepage and support are supported.

"extra": {
    "drupal-core-project-message": {
        "include-keys": ["homepage", "support"],
    }
}

Then you can include this information in your composer.json file, which you should probably be doing anyway.

Embedding the information in the extra section

You can specify text directly within the extra section by using the [event-name]-message key. This message should be an array, with one string for each line:

"extra": {
  "drupal-core-project-message": {
    "post-create-project-cmd-message": [
      "Thanks for installing this project.",
      "Read our documentation here: http://example.com/docs"
    ]
  }
}

These strings should be plain text, with markup suitable for Symfony's OutputInterface::writeln() method. See documentation here: https://symfony.com/doc/3.4/console/coloring.html

The -message section will always override -file for a given event.
