# mendex - Man Page

Japanese index processor

## Synopsis

mendex [-ilqrcgfEJSU] [-s sty] [-d dic] [-o ind] [-t log] [-p no] [-I enc] [--help] [--] [ idx0 idx1 idx2 ...]

## Description

The program mendex is a general purpose hierarchical index generator; it accepts one or more input files (.idx; often produced by a text formatter such as LaTeX), sorts the entries, and produces an output file which can be formatted. It is almost compatible with makeindex, and additional feature for handling readings of kanji words is also available.

The formats of the input and output files are specified in a style file. The readings of kanji words can be specified in a dictionary file.

The index can have up to three levels (0, 1, and 2) of subitem nesting.

## Options

-i

Take input from stdin, even when index files are specified.

-l

Set ´sort by character order´. By default, ´sort by word order´ is used. Details are described below.

-q

Quiet mode; send no message to stderr, except error messages and warnings.

-r

Disable implicit page range formation. By default, three or more successive pages are automatically abbreviated as a range (e.g. 1–5).

-c

Compress sequence of intermediate blanks (space(s) and/or tab(s)) into a space and ignore leading and trailing blank(s). By default, blanks in the index key are retained.

-g

Make Japanese index head A-line (A, Ka, Sa, ...) of the gojuon table (Japanese syllabary). By default, all the characters in the gojuon table are used.

-f

Force to output Kanji characters even non-existent in dictionaries.

-s sty

Employ sty as the style file.

-d dic

Employ dic as the dictionary file. The dictionary file is composed of lists of <index_word reading>.

-o ind

Employ ind as the output index file. By default, the file name is created by appending the extension ind to the base name of the first input file.

-t log

Employ log as the transcript file. By default, the file name is created by appending the extension ilg to the base name of the first input file.

-p no

Set the starting page number of the output index list to be no. The argument no may be numerical or one of the following: any (the next page to the end of contents), odd (the next odd page to the end of contents), even (the next even page to the end of contents).

-E

Set input/output character encoding to EUC-JP.

-J

Set input/output character encoding to JIS (ISO-2022-JP).

-S

Set input/output character encoding to Shift_JIS.

-U

Set input/output character encoding to UTF-8.

-I enc

Set internal character encoding to enc. The argument enc may be euc (EUC-JP) or utf8 (UTF-8). The default is set to utf8.

--help

Show summary of options.

--

Arguments after -- are not taken as options.

## Style File

The style file informs mendex about the format of the idx input files and the intended format of the final output file. The format is upper compatible with the one for makeindex. The style file contains a list of <specifier attribute> pairs. There are two types of specifiers: input and output. Pairs do not have to appear in any particular order. A line begun by ´%´ is a comment.

mendex has an additional feature to simplify the procedure of handling Japanese indexes, compared to makeindex. Users can save the effort of manually specifying a reading for every kanji word.

Japanese kanji words are usually sorted by the syllables of their readings (´Yomi´), which can be represented by kana (Hiragana, Katakana) scripts. mendex accepts index words specified in kana expression directly on an input file, and also accepts conversion from index words to kana scripts by referring to Japanese dictionaries.

Examples of internal simplification of syllables are shown below.

 かぶしきがいしゃ かふしきかいしや マッキントッシュ まつきんとつしゆ ワープロ わあふろ

The dictionary file consists of list with <´index_word´ ´reading´>. The index word can be written in any scripts (kanji, kana, etc), and the reading must be in Hiragana or Katakana scripts. The delimiter between the index word and its reading is one or more tab(s) or space(s).

An example of a Japanese dictionary is shown below.

 漢字 かんじ 読み よみ 環境 かんきょう α アルファ

Here, each index word is allowed to have only one Yomi. Though some kanji words (ex. 「表」) may have more than one Yomi´s (ex. 「ひょう」 and 「おもて」), only one of them can be registered in the dictionary. When some different Yomi´s are needed, they should be specified explicitly in kana expression (ex. \index{ひょう@表} or \index{おもて@表}) on the input file.

Moreover, a dictionary file is automatically referred by setting the file name at an environment variable INDEXDEFAULTDICTIONARY. The dictionary set by the environment variable can be used together with file(s) specified by -d option.

mendex sorts indexes as is (´sort by word order´) by default. Setting -l option, spaces between words in an index are truncated prior to sorting procedure (´sort by character order´).

Even when sort by character order, the index at output remains the original sequence without the truncation.

Follows show an example.

 sort by word order sort by character order X Window Xlib Xlib XView XView X Window

In addition, two sorting methods can be applied for indexes which contains both Japanese kana and other scripts (e.g. Latin script). By setting priority 0 (default) and 1 at a style file, a space between Japanese Kana and other scripts is inserted and not inserted respectively, prior to the sorting procedure.

Follows show an example.

 priority=0 priority=1 index sort indファイル indファイル index sort

## Environment Variables

mendex refers environment variables as follows.

INDEXSTYLE

Directory where index style files exist.

INDEXDEFAULTSTYLE

Index style file to be referred to as default.

INDEXDICTIONARY

Directory where dictionary files exist.

INDEXDEFAULTDICTIONARY

## Detail

Detailed specification is compatible with makeindex.

## Known Issues

When plural page number expression is used, .idx files should be specified along with the order of page numbers. Otherwise, wrong page numbers might be output.
