= Mercurial エクステンションを使う =
Mercurial の機能を任意のエクステンションで拡張しよう。

<<TableOfContents>>

== はじめに ==
Mercurial は安全で分かりやすいコマンドセットを提供しており、たいていのユーザーがその機能を満足できるように設計されています。 Mercurial のパワーユーザーはエクステンションを活用できるかもしれません。エクステンションを使うと、強力な新機能を Mercurial のコアに統合することができます。

<!> エクステンションが提供する機能は、 Mercurial のポリシー、つまり、安全性、信頼性、使い易さを満たしていないかもしれません。

エクステンションのヘルプは '`hg help extensions`' で表示できます。有効にしたエクステンションのヘルプを見るには、 '`hg help <extension-name>`' を実行してください。

== エクステンションを有効にする ==
エクステンション "foo" を有効にするには、 そのエクステンションが Mercurial とともに配布されているか
Python のサーチパスに含まれている場合は、
対応するエントリーを hgrc ファイルに追加してください。 例:

{{{
[extensions]
foo =
}}}
エクステンションをフルパスで指定してもかまいません (.py ファイル名か {{{__init__.py}}} のあるフォルダ名):

{{{
[extensions]
myfeature = ~/.hgext/myfeature.py
}}}
Mercurial と共に配布されていないエクステンションを使うには、ダウンロード後どこでも良いのでファイルシステム上に置いてください。この例では、 {{{~/.hgext/}}} にダウンロードしています。 '''注意: Windows 環境でディレクトリを指定する場合は、末尾にバックスラッシュをつけないでください。 (Bts:issue4187)'''

上位スコープの hgrc で有効になっているエクステンションを特に無効化したい場合は、 ! をパスの前に足してください:


{{{
[extensions]
# /path/to/extension/bar.py にある bar エクステンションを無効化
bar = !/path/to/extension/bar.py
# baz エクステンションのパスを指定しなくても同じこと
baz = !
}}}
たいていのエクステンションは、同じ設定ファイル上の専用セクションで細かい設定ができるようになっています。
