Help:Extension:Translate/環境設定

This page is a translated version of the page Help:Extension:Translate/Configuration and the translation is 100% complete.

MediaWiki 言語拡張機能群には翻訳拡張機能の設定に不可欠なコード類とインストールの手順が揃っています。このページでは追加の機能を求めている利用者で、インストール手順の紹介と必須条件のページがお役に立たなかった人向けに利用できるオプションの詳細を説明します。

サンプルの設定

この環境設定は MediaWiki のディレクトリLocalSettings.php配下に入ります。

wfLoadExtension( 'Translate' );
$wgGroupPermissions['translator']['translate'] = true;
$wgGroupPermissions['translator']['skipcaptcha'] = true; // T36182: needed with ConfirmEdit
$wgTranslateDocumentationLanguageCode = 'qqq';

# ページ翻訳へのアクセスを許すにはこれを追加
$wgGroupPermissions['sysop']['pagetranslation'] = true;

# 機械翻訳サービス用の個人 API キー
#$wgTranslateTranslationServices['Apertium']['key'] = '';

利用者権限

Translate 拡張機能は、以下の利用者権限を新たに導入します:

利用者権限	定義	説明
`translate`	翻訳用インターフェイスを使用して編集	利用者が翻訳を編集できるようにします。
`translate-manage`	メッセージ群を管理	利用者が Web インターフェイスでメッセージ群の更新や管理をできるようにします。
`translate-import`	オフラインでの翻訳を取り込み	ウェブのインターフェースを使い、利用者自身がオフラインツールから翻訳の更新をインポートできるようにします（まだ安定版ではありません）。このグループはオプションです。外部のソースから翻訳をインポーする必要がない場合は不用です。
`pagetranslation`	ページの版を翻訳対象に指定	利用者が本文ページの翻訳を管理できるようにします。
`translate-messagereview`	翻訳を査読	利用者が翻訳を査読済みにできるようにします。
`translate-proofr`	-	このグループには、`translate-messagereview` の権限と、他の利用者を `translate-proofr` グループに追加する権限があります。
`translate-groupreview`	メッセージ群のワークフローの状態を変更	グループのワークフローの状態を変更できるようにします。このグループはオプションで、$wgTranslateWorkflowStatesが既定で無効な場合には不要です。有効にするとワークフローの状態は$wgTranslateWorkflowStatesの変数に設定されます。

環境設定の変数

下記の説明文書は利便性のためにTranslate.phpから転記したものです。環境設定のオプションは時間の経過で変化するため、何かおかしいと感じた場合にはインストールされた Translate.php の説明文書が最適です。ご参考までに下記は2016-04-21時点の記録です。

この節はTranslateが拡張機能に登録されて以来、更新されていません。現在、この種類の説明文書をextension.jsonから自動生成するいい方法はありません。

 *   * PHP::Serialization.
 *   * File::Slurp
 *
 * You should be able to do this with:
 *   for module in 'YAML::Syck' 'PHP::Serialization' 'File::Slurp'; do cpanp -i $module; done
 *
 * For the shell to work, you also need an en.UTF-8 locale installed on your system.
 * add a line "en.UTF-8" to your /etc/locale.gen or uncomment an existing one and run locale-gen
 * if you do not have it already.

トラブルシューティング

翻訳ページが空白もしくはエラー表示'Unbalanced `‎<translate>` tag' が出る

終了タグ ‎</translate> が存在する場合は、翻訳元ページが長大すぎます。特定の翻訳でこの問題発生のきっかけは、翻訳元ページがおよそ50KB以上だった場合です。

対象ページを短くするか、pcre.backtrack_limit を拡張するため、LocalSettings.php 内の

ini_set( 'pcre.backtrack_limit', 400000 );

か、ご利用の PHP 環境設定 (php.ini) の

pcre.backtrack_limit=400000

を設定します。

失敗した翻訳をUnknown error: "tpt-unknown-page"で保存

この問題の原因は、ページの翻訳指定は終わったのにバックグラウンドのジョブが未処理だからです。その場合、主導でジョブキューを実行するか、さらに適した対策としてManual:ジョブキューに記述のあるとおりジョブの連続実行を設定します。それでも解決しない場合はphp extensions/Translate/scripts/createMessageIndex.phpの実行を試します。
