jlreq LaTeX Document Class

The jlreq class uses specific JFM names. If you use other packages, ensure they do not override these settings if you want to maintain jlreq's typography.

pLaTeX / upLaTeX

The JFM name follows the pattern [u][b][z]jlreq[g][-v]. The flags are:

• u: Used with upLaTeX.
• b: Used when hanging_punctuation is specified in class options.
• z: Used when open_bracket_pos=zenkakunibu_nibu is specified.
• g: For Gothic fonts.
• -v: For vertical writing. Example: A pLaTeX source with open_bracket_pos=zenkakunibu_nibu but without hanging punctuation uses zjlreq for horizontal Mincho.

LuaLaTeX

• Horizontal writing: jlreq
• Vertical writing: jlreqv (also used for Gothic).

The use_reverse_pagination class option enables reverse pagination functionality. This defines a read-only counter named jlreqreversepage. You can interact with it using standard LaTeX commands:

• \thejlreqreversepage: Returns the counter value as an Arabic numeral.
• \arabic{jlreqreversepage}: Standard counter access.
• \value{jlreqreversepage}: Standard counter access.

\documentclass[use_reverse_pagination]{jlreq}

The jlreq class uses a keyval format for configuration. You can set parameters via document class options or the \jlreqsetup command.

Note on Class Options: Due to LaTeX implementation constraints, some inputs might not be accepted directly as class options. A common workaround is to remove spaces from the option values.

Syntax Conventions:

• [A/B]: Selects option A or B (e.g., [A/B/C]).
• <dimension>: Standard TeX dimensions. You can use expressions like 10pt+10pt.
  • Special values: Q and H are interpreted as 0.25mm.
  • Full-width units: Use \zw or \zh within \jlreqsetup to specify full-width dimensions.
• <code ext>: Raw LaTeX code.
• <font_setting_code ext>: Font commands like \Large or \bfseries.
• <counter_name ext>: Name of a LaTeX counter.

The jlreq class uses custom JFMs to ensure correct Japanese typesetting. Depending on your engine and class options, different JFM names are applied.

pLaTeX / upLaTeX

JFM names follow the pattern [u][b][z]jlreq[g][-v].

• u: used with upLaTeX.
• b: used if hanging_punctuation option is enabled.
• z: used if open_bracket_pos=zenkakunibu_nibu is enabled.
• g: used for gothic fonts.
• -v: used for vertical writing.

Example: Using pLaTeX with open_bracket_pos=zenkakunibu_nibu but without hanging punctuation results in the JFM zjlreq for horizontal mincho.

LuaLaTeX

• Horizontal writing: jlreq
• Vertical writing: jlreqv
• Gothic fonts use the same JFM as mincho.

Note: If you use other packages that reset JFM settings, you may need to explicitly set package options to maintain the jlreq JFMs.

To use jlreq, you must first generate the necessary Japanese Font Metric (JFM) files using make. Once generated, place the files in your TeX tree as follows:

• *.tfm $\rightarrow$ $TEXMF/fonts/tfm/public/jlreq
• *.vf $\rightarrow$ $TEXMF/fonts/vf/public/jlreq
• jfm-jlreq.lua, jfm-jlreqv.lua, jfm-jlreq-jidori.lua, jfm-jlreqv-jidori.lua $\rightarrow$ $TEXMF/tex/luatex/jlreq
• jlreq.cls, jlreq-helpers.sty $\rightarrow$ $TEXMF/tex/latex/jlreq

You can automate this process by running make install, which will copy the files to $TEXMFHOME.

You can install the jlreq package using one of two methods:

Method 1: Automatic Installation

Run the following command to install all files into your $TEXMFHOME directory:

make install

Method 2: Manual Installation

1. Generate the JFM files by running:

   make

2. Move the generated files to the following locations in your $TEXMF tree:
   • *.tfm $\rightarrow$ $TEXMF/fonts/tfm/public/jlreq
   • *.vf $\rightarrow$ $TEXMF/fonts/vf/public/jlreq
   • jfm-jlreq.lua, jfm-jlreqv.lua, jfm-jlreq-jidori.lua, jfm-jlreqv-jidori.lua $\rightarrow$ $TEXMF/tex/luatex/jlreq
   • jlreq.cls, jlreq-helpers.sty $\rightarrow$ $TEXMF/tex/latex/jlreq

Load the package using egin{document} with the \[\usepackage] command. You must specify the TeX engine and the DVI driver.

Important: Do not use the tombow option in your document class when using this package.

If you encounter conflicts with paper size settings, consider using a more powerful package like bxpapersize.

\usepackage[dvipdfmx,platex]{jlreq-trimmarks}

The jlreq class does not provide built-in functionality for setting fonts. When using LuaLaTeX, you should use the following packages (included in the LuaTeX-ja package):

• luatexja-fontspec
• luatexja-preset

If you are using dvipdfmx, it is recommended to use the PXchfon package.

Use these class options to control how punctuation and brackets behave at the start of lines.

• open_bracket_pos=[zenkaku_tentsuki/zenkakunibu_nibu/nibu_tentsuki]: Controls indentation of opening brackets at the start of a paragraph:
  • zenkaku_tentsuki: Full-width characters are indented.
  • zenkakunibu_nibu: Full-width at start of paragraph, half-width at line breaks.
  • nibu_tentsuki: Half-width indentation at the start of a line.
• hanging_punctuation: Enables hanging punctuation.
