Harusame extracts a version of the HTML document written in the specified natural language, from a source HTML document that contains paragraphs in multiple natural languages. 春雨は、複数の自然言語の文章をまとめた元となる HTML 文書から、指定した自然言語の版の HTML 文書を取り出すツールです。
The document management of a multilingual Web site where there are multiple versions of a (conceptually same) document is somewhat difficult in general. If the author of an HTML document wants to edit a part of the document, then he or she has to ensure not to forget updating translations at the same time, otherwise documents in different language versions also differ in their content versions. 多言語 Web サイトで (実際には同じ内容の) 文書の版を管理するのは大変です。 HTML 文書の著者が一部でも変更しようと思うと、 他の言語の翻訳も同時に更新しておかないと、言語間で文書の版が違ってしまいます。
Using harusame, one can generate versions of an HTML document in different language from one source HTML document that contains paragraphs written in all of those languages, such that authors no longer have to manage different content versions and different language versions in separate files. 春雨を使えば複数言語の HTML 文書を1つの元となる HTML 文書から生成できます。 段落毎に各言語の翻訳文を並べた元文書を用意すればよいので、 著者は別々のファイルで別々の言語の別々の版を管理する煩わしさから開放されます。

First, prepare a source HTML document html-document.src. The document can be marked up in HTML as usual, except for the special markup for harusame to identify alternative blocks written in various languages.
An input document might look like:
<!DOCTYPE HTML>
<html lang=mul>
<title>Example Document</title>
<h1 data-lang-container>
<span lang=en>Example document</span>
<span lang=ja>文書の例</span>
</h1>
<p data-lang-container>
<span lang=en>This is an example of document with multiple languages.</span>
<span lang=ja>これは複数の言語で記述された文書の例です。</span>
Then, invoke the harusame command for each language to
generate, as:
$ harusame --lang en < html-document.src > html-document.en
$ harusame --lang ja < html-document.src > html-document.ja
For more information on the harusame's command-line
options, see its documentation.
Special markup for harusame processing is
represented as data-lang-* attributes on HTML
elements, as follows:
data-lang-container
If this attribute is specified to an HTML element, then it is treated as a container element that contains versions of the content in various languages.
An element with this attribute must contain one or more HTML
elements. One of them, whose language (lang attribute
value) matches with the language specified as --lang
command-line option, is selected. If there are more than one
such elements, then the first one is selected. If there is no
element whose language matches to the --lang option, then
the first element (of whatever language) is selected.
If the attribute value is replace, then the element
itself is replaced by the selected element. Otherwise, the
content of the element is replaced by the selected
element.
data-lang-content
If this attribute is specified to an HTML element, then its content is replaced by the content of another element.
If this attribute is specified, its value must be an ID of another HTML element in the document.
A child element of the element addressed by the ID is
selected in the similar way to the
data-lang-container attribute. Then, the content of the
element with the data-lang-content attribute is replaced
by the text content (the value of the textContent IDL
attribute) of the selected element.
If the element addressed by the ID has
data-lang-declaration attribute, then the element will be
removed from the document at the end of the whole processing.
This attribute is useful when an HTML element does not allow
elements to be inserted within it . For example, the content model of
the title element does not allow child elements. In such
a case, instead of inserting elements with lang
attribute, this attribute can be used to point to translations of the
title element content, as follows:
<title data-lang-content="title-content">Example</title>
<div id="title-content" data-lang-declaration hidden>
<span lang=en>Example</span>
<span lang=ja>例</span>
</div>
Note that the pointed element, i.e. the div element,
has the data-lang-declaration
attribute specified. In many (though not all) cases, the pointed
translations do not form the actual content of the document and
therefore the attribute ask to harusame to get rid of
them from the document at the end of the processing.
data-lang-declaration
This attribute indicates that the element declares a set of alternatives in various languages.
This attribute must not be used for an element that is not pointed
by a data-lang-content attribute in the same document.

This software requires Perl 5.8 or later. 春雨の動作には Perl 5.8 以降が必要です。
It also depends on manakai-core and CharClass packages, which are submodules of the harusame Git repository. 春雨はmanakai-core と CharClass も使っています (Git リポジトリーのサブモジュールです)。
Harusame is developed using Git. Git repository (GitHub) can be cloned by the following commands: 春雨は Git を使って開発しています。 Git リポジトリ(GitHub) は次のようにして clone できます。
