The Linter extension tracks lint errors from an external service. Currently the main use case is to track the errors identified by Parsoid and expose them to editors. Help for users wanting to fix errors is available at Help:Extension:Linter .

Installation

This extension requires linting enabled in Parsoid's configuration.

• Download and move the extracted Linter folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Linter
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'Linter' );
  

• Run the update script which will automatically create the necessary database tables that this extension needs.Add the suggested configuration:
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

Add the following to your LocalSettings.php file, editing as necessary:

// Load Parsoid
wfLoadExtension(
    'Parsoid',
	"$IP/vendor/wikimedia/parsoid/extension.json"
);

$wgParsoidSettings = [
    'useSelser' => true,
    'linting' => true
];

$wgVisualEditorParsoidAutoConfig = false; // to make linting work

$wgVirtualRestConfig = [
	'paths' => [],
	'modules' => [
		'parsoid' => [
			'url' => 'https://www.mysite.wiki/w/rest.php',
			'domain' => 'www.mysite.wiki',
			'forwardCookies' => true,
			'restbaseCompat' => false,
			'timeout' => 30
		],
	],
	'global' => [
		'timeout' => 360,
		'forwardCookies' => false,
		'HTTPProxy' => null
	]
];

Upgrading to MediaWiki 1.43.x

Updating the extension's database table for MediaWiki 1.43 may need special attention.

The "update.php" script runs two time-consuming migration scripts that update the Linter database table at approximately 500 rows per second. Running "update.php" directly is recommended.

For large Linter tables where extended maintenance time is not feasible:

Upgrading from 1.40+

1. Set $wgLinterWriteNamespaceColumnStage = true
2. Set $wgLinterWriteTagAndTemplateColumnsStage = true
3. Run $ path/to/mediawiki/maintenance/run.php migrateNamespace
4. Run $ path/to/mediawiki/maintenance/run.php migrateTagTemplate
5. Proceed with MediaWiki and extensions update to 1.43

Upgrading from 1.39 or earlier

1. Update to MediaWiki 1.42 first
2. Then follow steps above for 1.40+ upgrade

Linter categories

A list of linter categories is available in site info properties.

Bootstrap or reprocess all pages

Instead of running refreshLinks.php , it's possible to populate lint errors by querying parsoid directly. See phab:T161556#3184216 for an example script.

Special pages

The extension provides the Special:LintErrors page.

Configuring available lints

The Special:LintErrors page displays available lints with associated priority that have been defined in the configuration parameter $wgLinterCategories.

Each linter category has the following fields:

• dbid: the unique id associated with the lint category used in the database.
• enabled: whether the lint rule is enabled. If lints are disabled they will not be accessible from the special page.
• priority: either none, low, medium or high. Lints that are none will not be listed on Special:LintErrors but will be accessible through the web via the associated subpage.
• no-params: no parameters are associated with the lint category.
• has-name: indicates that the lints are expected to contain a name parameter, so the special page displays the column in the UI.

For new lints, it is recommended that by default they are defined as priority none and that they are promoted after testing and some discussion with the linting community. No formal process exists for promoting lint priorities at time of writing.
