Manual:Writing maintenance scripts/ja

Version 1.16 of MediaWiki introduced the maintenance class to make it easier to write command-line MediaWiki maintenance scripts.

''これは、ステップバイステップのチュートリアルとして書かれています. ''

スクリプトの例
To describe writing these maintenance scripts, we'll walk through an helloWorld.php, a script that simply prints “Hello, World”. This program contains the minimum amount of code needed to run as well as the expected copyright header (for alternative headers, see copyright headers):

The program will just print out “Hello, World!” but already has a --help (and other command line options). Sample output:

 $ php helloWorld.php Hello, World! $ php helloWorld.php --help

Usage: php helloWorld.php [--conf|--dbpass|--dbuser|--globals|--help|--quiet|--wiki] conf : Location of LocalSettings.php, if not default dbpass : The password to use for this script dbuser : The DB user to use for this script globals : Output globals at the end of processing for debugging help : Display this help message quiet : Whether to supress non-error output wiki : For specifying the wiki ID 概要:

 * 行 14
 * We override Maintenance class and then, in


 * 行 20、21
 * tell the Maintenance class to run the script using the HelloWorld class, only if being executed from the command line.


 * 行 15
 * The execute function that we've provided is executed.

オプションと引数の解析
Greeting the world is all well and good, but we want to be able to greet individuals, too.

To add an option, add a constructor with a call addOption and update the execute</tt> method to use the new option. addOption's parameters are $name, $description, $required = false, $withArg = false, $shortName = false:

This time, when executed, the output of the helloWorld.php</tt> script changes depending on the argument provided:

<pre style="overflow:auto;"> $ php helloWorld.php Hello, World! $ php helloWorld.php --name=Mark Hello, Mark! $ php helloWorld.php --help Usage: php helloWorld.php [--conf|--dbpass|--dbuser|--globals|--help|--name|--quiet|--wiki] …   name : Who to say Hello to
