Config Importer and Tools

This module aims to cover development needs with managing configurations during project development.

Importing all configs during development is not convenient and can lead to a bad behaviour with overwriting or deleting configs or content from a site.

So there is a need for importing only of specific configs via hook_update_N().

Usage

All the work happening with the config_import.importer service. Let's instantiate it:

/* @var Drupalconfig_importConfigImporterServiceInterface $config_importer */
$config_importer = Drupal::service('config_import.importer');

By default, import and export operations will use the sync directory. But, if needed, it could be changed to a path of existing directory or type of already configured configuration directories. For instance:

// $config_importer->setDirectory(CONFIG_STAGING_DIRECTORY);
$config_importer->setDirectory('/var/config');

You may do so to import existing configs:

$config_importer->importConfigs(['core.extension']);

And export can be achieved with a similar construction:

$config_importer->exportConfigs(['core.extension']);

Features integration

To revert/import features you have to enable the features module first:

drush en features -y

Get instance of service:

/* @var Drupalconfig_importConfigFeaturesImporterServiceInterface $features_importer */
$features_importer = Drupal::service('config_import.features_importer');

And do the import:

$features_importer->importFeatures(['feature1', 'feature2']);

Drush integration

Execute the next command to see the list of available commands from a group:

drush help --filter=config_import

Then use the following syntax to find out more information about concrete command:

drush help COMMAND_NAME

Example use cases

/**
 * Revert custom block feature.
 */
function ygh_master_update_8024() {
  Drupal::service('config_import.features_importer')->importFeatures(['openy_block_custom_simple']);
}

/**
 * Update HTML format config.
 */
function ygh_master_update_8025() {
  /* @var Drupalconfig_importConfigImporterServiceInterface $config_importer */
  $config_importer = Drupal::service('config_import.importer');
  $config_importer->setDirectory(YGH_CONFDIR);
  $config_importer->importConfigs(['filter.format.html']);
}

To do

• Create UI for making manual config changes convenient

For updating specific property in config:

1) go to related to this config module

2) create new hook_update_N in openy_*.install file

3) in update add next code (this is example):

$config = drupal_get_path('module', 'openy_media_image') . '/config/install/views.view.images_library.yml';
$config_importer = Drupal::service('config_import.param_updater');
$config_importer->update($config, 'views.view.images_library', 'display.default.display_options.pager');

Where:

• $config variable contains path to config with config name
• "views.view.images_library" - config name
• "display.default.display_options.pager" - config specific property (you can set value from a nested array with variable depth)
