function install_profile_info in Drupal 8

Same name and namespace in other branches

1. 7 includes/install.inc \install_profile_info()
2. 9 core/includes/install.inc \install_profile_info()

Retrieves information about an installation profile from its .info.yml file.

The information stored in a profile .info.yml file is similar to that stored in a normal Drupal module .info.yml file. For example:

• name: The real name of the installation profile for display purposes.
• description: A brief description of the profile.
• dependencies: An array of shortnames of other modules that this install profile requires.
• install: An array of shortname of other modules to install that are not required by this install profile.

Additional, less commonly-used information that can appear in a profile.info.yml file but not in a normal Drupal module .info.yml file includes:

• distribution: Existence of this key denotes that the installation profile is intended to be the only eligible choice in a distribution and will be auto-selected during installation, whereas the installation profile selection screen will be skipped. If more than one distribution profile is found then the first one discovered will be selected. The following subproperties may be set:
  • name: The name of the distribution that is being installed, to be shown throughout the installation process. If omitted, drupal_install_profile_distribution_name() defaults to 'Drupal'.
  • install: Optional parameters to override the installer:
    • theme: The machine name of a theme to use in the installer instead of Drupal's default installer theme.
    • finish_url: A destination to visit after the installation of the distribution is finished

Note that this function does an expensive file system scan to get info file information for dependencies. If you only need information from the info file itself, use \Drupal::service('extension.list.profile')->getExtensionInfo().

Example of .info.yml file:

   name: Minimal
   description: Start fresh, with only a few modules enabled.
   install:
     - block
     - dblog

Parameters

$profile: Name of profile.

$langcode: Language code (if any).

Return value

The info array.
