Setting up sfkanbun.sty #

The style file for kunten materials, kunten2e.sty, can be used with upLaTeX but is not compatible with LuaLaTeX. Some existing document files were created using this kunten2e.sty style file.

The sfkanbun package (sfkanbun.sty for Kanbun texts) originates from the work on Typesetting Kanbun with Kundoku Marks (漢文の訓点文の組版), featured in “Introduction to Vertical and Horizontal Document Composition” (入門・縦横文書術) by Fujita Shinsaku. A modified version of this style file, adapted for LuaLaTeX compatibility and renamed sfkanbun-lua.sty, has been made available at https://github.com/shikeda/rose.

Therefore, to minimize changes to existing TeX source files, frequently used macros in kunten2e.sty have been mapped to macros in sfkanbun.sty that provide equivalent functionality, or compatibility has been otherwise ensured.

Sōgyō (双行 - Double-Line Annotations) #

Sōgyō (双行) refers to a type of Interlinear Note (割注, warichū), specifically one that is typically presented in two lines.

In kunten2e.sty, this is input as follows:

\sougyou{right-hand line}{left-hand line}

(In vertical text, the “right-hand line” is typically the first line of the two-line note, and the “left-hand line” is the second.)

In sfkanbun.sty, the \tagyobox command (for multi-line interlinear notes) is used:

\tagyobox{item 1 \\ item 2 \\ ...}

Since an Interlinear Note (warichū) often consists of just two lines (corresponding to “item 1” and “item 2” above), the following custom LaTeX command can be defined to simplify input for such cases:

\newcommand{\sougyou}[2]{\tagyobox{#1 \\ #2}}

Nested Double-Line Annotations (副双行, Fukusōgyō) #

A fukusōgyō (副双行) refers to creating an additional double-line annotation (sōgyō) within an existing sōgyō (double-line interlinear note). In kunten2e.sty, this is input as follows:

\hukusougyou{right-hand line}{left-hand line}

This functionality can be achieved in sfkanbun.sty using its feature for nested multi-line interlinear notes (\fukutagyobox).

\fukutagyobox{item 1 \\ item 2 \\ ...}

Since a nested double-line annotation typically requires only two items (lines), the following custom LaTeX command can be defined to simplify input for such cases:

\newcommand{\hukusougyou}[2]{\fukutagyobox{#1 \\ #2}}

Okurigana and Kaeriten Marks (送り仮名、返り点) #

The \kundoku command from sfkanbun.sty is useful for typesetting okurigana (送り仮名, inflectional kana endings) and kaeriten (返り点, guiding marks for Japanese reading order of Kanbun). Its syntax is:

\kundoku[control_options]{base_character}{ruby_text}{okurigana}{kaeriten_mark}[shoulder_kaeriten_mark](punctuation_mark)

The (punctuation_mark) argument is optional.

Ruby (ルビ) #

Several macros are available for using ruby (ルビ, small phonetic glosses alongside characters). After experimentation, we decided to use luatexja-ruby.sty.

The basic syntax is:

\ltjruby[⟨option⟩]{親|文|字}{おや|も|じ}

In this example, the command specifies that the ruby text ‘おや’ (oya) is to be applied to the base character ‘親’; ‘も’ (mo) to ‘文’; and ‘じ’ (ji) to ‘字’.

An alias \ruby is also defined for this command.

Although the exact circumstances are no longer recalled, ruby was previously applied using a custom command named \ukun. To avoid rewriting original files that used this command, \ukun has been (re)defined as follows:

\newcommand{\ukun}[2]{\ltjruby{#1}{#2}}

Alternatively, all instances of \ukun could be globally replaced with \ruby.
