Making MediaWiki config so

Usage for extension maintenance

A "baseline" extension config defines all the extensions that could possibly be installed in your setup. It must fully define the name, version and either composer or repo properties. Additional optional properties are also available and discussed later.

- name: SemanticExtraSpecialProperties
  composer: "mediawiki/semantic-extra-special-properties"
  update_php_on_change: "all"
  version: "2.0.0"

- name: Echo
  repo: https://github.com/wikimedia/mediawiki-extensions-Echo.git
  version: "d34f32174c23818dbf057a5482dc6ed4781a3a25"
  update_php_on_change: "code-changes"
  config: |
    $wgEchoEmailFooterAddress = $wgPasswordSender;

- name: NumerAlpha
  repo: https://github.com/wikimedia/mediawiki-extensions-NumerAlpha.git
  version: tags/0.7.0
  legacy_load: True

- name: Elastica
  repo: https://github.com/wikimedia/mediawiki-extensions-Elastica.git
  version: "REL1_35"
  update_php_on_change: "code-changes"
  composer_merge: True

- name: VisualEditor
  repo: https://github.com/wikimedia/mediawiki-extensions-VisualEditor.git
  version: "REL1_35"
  update_php_on_change: "code-changes"
  git_submodules: True

- name: Vector
  skin: true
  repo: https://github.com/wikimedia/mediawiki-skins-Vector.git
  version: "REL1_35"

A "specified" extension config then can specify which of the baseline to use as well as alter or add to it:

- name: SemanticExtraSpecialProperties
- name: VisualEditor
  repo: "https://github.com/yourpersonal/repo1"
  version: master
- name: Elastica
  version: b929bc6e56b51a8356c04b3761c262b6a9a423e3
- name: AnExtensionNotInBaseline
  repo: "https://github.com/yourpersonal/repo2"
  version: tags/1.2.3
- name: Modern
  skin: true
  repo: https://github.com/wikimedia/mediawiki-skins-Modern.git
  version: "REL1_35"

get-ext command

Running the following command should use git to get the non-Composer extensions and skins specified above and put them in /path/to/mediawiki in extensions and skins:

mw-picard get-ext \
	--baseline=/path/to/baseline.yml
	--specifier=/path/to/config/specifier.yml
	--mediawiki=/path/to/mediawiki
	# if extensions or skins are in non-standard locations, add --extensions and --skins

This will create the following directories in /path/to/mediawiki/extensions:

VisualEditor <-- for this it will run `git submodule update --init` because git_submodules:true
AnExtensionNotInBaseline

And the following in /path/to/mediawiki/skins:

Modern

It will also create /path/to/mediawiki/composer.local.json as follows:

{
	"require": {
		"mediawiki/semantic-extra-special-properties": "2.0.0"
	},
	"extra": {
		"merge-plugin": {
			"include": ["extensions/Elastica/composer.json"]
		}
	}
}

And will run composer install/update to get those extensions.

Next it will generate a /path/to/config/specifier.installed.yml file after all other changes are made. If one of these files existed prior to this run, it would have been used to determine which extensions required update. For git-installed extensions this means simply getting new versions for each extension necessary. For Composer-installed extensions the whole composer.local.json is re-written and composer install/update commands are run if any composer-installed extension is modified.

Next it will generate /path/to/mediawiki/extensions/ExtensionSettings.php to be included in /path/to/mediawiki/LocalSettings.php.

Lastly, it will generate /path/to/config/update-php-required.json which looks like the following if only certain wikis need update.php run:

{ "wikis": ["my-wiki", "your-wiki"] }

Or like the following if all wikis need it run:

{ "all": true }

If no wikis need update.php, no file is created. Whether or not update.php is run is determined by whether an extension with update_php_on_change: true was changed.
