:mod:`habachen` --- 高速な日本語文字種変換モジュール
====================================================

.. module:: habachen

.. testsetup:: *

  import habachen
  __name__ = '<doctest>'


--------------

このモジュールは、日本語の全角／半角と、ひらがな／カタカナを相互変換する関数を提供します。

利用可能な関数は以下の通りです：

.. function:: hankaku_to_zenkaku(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str
              to_zenkaku(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str
              han_to_zen(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str

  文字列を受け取り、それに含まれる半角文字を対応する全角文字に変換した新しい文字列を返します。\
  既定の動作では、ASCII文字と半角カタカナ・半角句読点・半角鉤括弧が全角に変換されます。\
  制御文字は変換されません。 '\\' (U+005C) は、全角のバックスラッシュ '＼' (U+FF3C) に変換されます。\
  半角の濁点／半濁点は、直前のカナとの組み合わせに対応する全角の合成済み文字が存在する場合には\
  それに変換され、存在しない場合には、それぞれ結合文字でない全角の濁点 (U+309B)、半濁点 (U+309C) へと\
  変換されます。
  *ascii* オプションを False に設定すると、ASCII文字（数字を除く）が変換されなくなります。
  *digit* オプションを False に設定すると、半角数字 (ASCII) が変換されなくなります。
  *kana* オプションを False に設定すると、半角カタカナ・半角句読点・半角鉤括弧が変換されなくなります。

  以下が使用例です:

  .. doctest::

    # 半角から全角に変換する。既に全角のものは変化なし
    >>> habachen.hankaku_to_zenkaku('abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ')
    'ａｂｃ！？０１２ハンカクモジ全角カタカナ'

    # to_zenkaku(), han_to_zen() というエイリアスが用意されている。機能は同じ
    >>> habachen.to_zenkaku('abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ')
    'ａｂｃ！？０１２ハンカクモジ全角カタカナ'
    >>> habachen.han_to_zen('abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ')
    'ａｂｃ！？０１２ハンカクモジ全角カタカナ'

    # 数字以外の ASCII 文字の変換を行わない
    >>> text = 'abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ'
    >>> habachen.han_to_zen(text, ascii=False)
    'abc!?０１２ハンカクモジ全角カタカナ'

    # 数字の変換を行わない
    >>> text = 'abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ'
    >>> habachen.han_to_zen(text, digit=False)
    'ａｂｃ！？012ハンカクモジ全角カタカナ'

    # 半角カタカナの変換を行わない
    >>> text = 'abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ'
    >>> habachen.han_to_zen(text, kana=False)
    'ａｂｃ！？０１２ﾊﾝｶｸﾓｼﾞ全角カタカナ'

    # ASCII 文字と数字の変換を行わない（半角カタカナのみ変換）
    >>> text = 'abc!?012ﾊﾝｶｸﾓｼﾞ全角カタカナ'
    >>> habachen.han_to_zen(text, ascii=False, digit=False)
    'abc!?012ハンカクモジ全角カタカナ'

.. function:: zenkaku_to_hankaku(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str
              to_hankaku(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str
              zen_to_han(text: str, /, *, ascii: bool = True, digit: bool = True, kana: bool = True) -> str

  文字列を受け取り、それに含まれる全角文字を対応する半角文字に変換した新しい文字列を返します。\
  既定の動作では、対応するASCII文字が存在する全角文字、全角カタカナ、\
  日本語の全角句読点と全角鉤括弧が半角に変換されます。 全角チルダ '～' (U+FF5E) に加え、\
  波ダッシュ '〜' (U+301C) もASCII文字の半角チルダ '~' (U+007E) に変換されます。\
  半角数字に変換されるのは、全角のアラビア数字 (U+FF10-U+FF19) のみです。
  *ascii* オプションを False に設定すると、ASCII文字（数字を除く）への変換が行われなくなります。
  *digit* オプションを False に設定すると、半角数字 (ASCII) への変換が行われなくなります。
  *kana* オプションを False に設定すると、半角カタカナや半角句読点・半角鉤括弧への変換が行われなくなります。

  以下が使用例です:

  .. doctest::

    # 全角から半角に変換する。既に半角のものは変化なし
    >>> habachen.zenkaku_to_hankaku('ａｂｃ！？０１２ゼンカクモジﾊﾝｶｸﾓｼﾞ')
    'abc!?012ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'

    # to_hankaku(), zen_to_han() というエイリアスが用意されている。機能は同じ
    >>> habachen.to_hankaku('ａｂｃ！？０１２ゼンカクモジﾊﾝｶｸﾓｼﾞ')
    'abc!?012ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'
    >>> habachen.zen_to_han('ａｂｃ！？０１２ゼンカクモジﾊﾝｶｸﾓｼﾞ')
    'abc!?012ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'

    # 数字以外の ASCII 文字への変換を行わない
    >>> text = 'ａｂｃ！？０１２ゼンカクモジﾊﾝｶｸﾓｼﾞ'
    >>> habachen.zen_to_han(text, ascii=False)
    'ａｂｃ！？012ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'

    # 全角数字の変換を行わない
    >>> text = 'ａｂｃ！？０１２ゼンカクモジﾊﾝｶｸﾓｼﾞ'
    >>> habachen.zen_to_han(text, digit=False)
    'abc!?０１２ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'

    # 全角カタカナの変換を行わない

    'ａｂｃ！？０１２ｾﾞﾝｶｸﾓｼﾞﾊﾝｶｸﾓｼﾞ'

.. function:: hiragana_to_katakana(text: str, /, ignore: Iterable[str] = '', *, hankaku: bool = False) -> str
              to_katakana(text: str, /, ignore: Iterable[str] = '', *, hankaku: bool = False) -> str
              hira_to_kata(text: str, /, ignore: Iterable[str] = '', *, hankaku: bool = False) -> str

  文字列を受け取り、それに含まれるひらがなを対応するカタカナ（既定では全角カタカナ）に変換した新しい文字列を返します。\
  オプション引数 *ignore* に含まれるひらがなは変換されません。
  *ignore* 引数に渡すことができるのは、ひらがな文字列、あるいはひらがな文字列のイテラブルで、\
  カタカナに変換できない文字を含んでいてはなりません。
  *hankaku* オプションを True に設定すると、ひらがなは全角カタカナではなく半角カタカナに変換されるようになります。

  以下が使用例です:

  .. doctest::

    # ひらがなをカタカナに変換する。ひらがな以外は変換されない
    >>> habachen.hiragana_to_katakana('もじれつの変換')
    'モジレツノ変換'

    # to_katakana(), hira_to_kata() というエイリアスが用意されている。機能は同じ

    'モジレツノ変換'
    >>> habachen.hira_to_kata('もじれつの変換')
    'モジレツノ変換'

    # ignore には、任意のイテラブル（リストなど）を指定可能。 ''.join(ignore) の結果が使われる
    >>> habachen.to_katakana('らりるれろやいゆえよわをん', ignore=['やゆよ', 'わ', 'ん'])
    'ラリルレロやイゆエよわヲん'

    # ひらがなを半角カタカナに変換
    >>> habachen.to_katakana('もじれつの変換', hankaku=True)
    'ﾓｼﾞﾚﾂﾉ変換'

.. function:: katakana_to_hiragana(text: str, /, ignore: Iterable[str] = '') -> str
              to_hiragana(text: str, /, ignore: Iterable[str] = '') -> str
              kata_to_hira(text: str, /, ignore: Iterable[str] = '') -> str

  文字列を受け取り、それに含まれる全角カタカナを対応するひらがなに変換した新しい文字列を返します。\
