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。

Contents

基本的な環境設定

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

include_once "$IP/extensions/Translate/Translate.php";
$wgGroupPermissions['translator']['translate'] = true;
$wgGroupPermissions['translator']['skipcaptcha'] = true; // Bug 34182: 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。

 *   * 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

ページ翻訳

翻訳指定されたページの翻訳中に名前空間名の翻訳で問題 (症例: 定義が表示されない、ページ名がコロン記号で始まる) がある場合は、以下の2点を LocalSettings.php に追加します:

$wgExtraNamespaces[$wgPageTranslationNamespace]   = 'Translations';
$wgExtraNamespaces[$wgPageTranslationNamespace+1] = 'Translations_talk';

この問題は Language クラスをかなり早期に非スタブ化する要素があり、その後、名前空間を条件付きで翻訳可能に指定した場合に発生します。

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

もし閉じタグ</translate>が書いてあるなら、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。

PHPlot とフォント設定

特定の言語で文字が◻︎として表示される場合は、まず適切なフォント(字体)をインストール済みか確認します。それでも問題が解決しない場合は、フォントのバグ解消ログを実行します。その前に MediaWiki のキャッシュのクリアが必要な場合があります。システムによっては、PHP からfc-listコマンドが提供するフォントへのアクセスが禁止されています。

$wgDebugLogGroups['fcfont'] = '/path/to/writable/logfile';

TUX モード (新 UI) でメッセージが何も表示されない

$wgTranslateTasksを上書きした時は、必ずタスクcustomが除外されていないことを確認します。

Special:Translate ページでツールを読み込まない

このような表示があり「メッセージを読み込み中です…」という表示がずっと続く場合は、ResourceLoaderが破損しています。$wgResourceLoaderMaxQueryLength = 1024; にせって、もしくはユニットが正常に作動するまで、設定値を小さく変更します。

それで解決しない場合には、UniversalLanguageSelector のインストールと有効化は済んだか確認できますか?

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。
