texindy is the LaTeX-specific command of xindy, the flexible indexing system. It takes a raw index as input, and produces a merged, sorted and tagged index. Merging, sorting, and tagging is controlled by xindy modules, with a convenient set already preloaded.

Files with the raw index are passed as arguments. If no arguments are passed, the raw index will be read from standard input.

A good introductionary description of texindy appears in the indexing chapter of the LaTeX Companion (2nd ed.)

If you want to produce an index for LaTeX documents with special index markup, the command xindy(1) is probably more of interest for you.

texindy is an approach to merge support for the make-rules framework, own xindy modules (e.g., for special LaTeX commands in the index), and a reasonable level of MakeIndex compatibility.

"--version" / -V
output version numbers of all relevant components and exit.
"--help" / -h / -?
output usage message with options explanation.
"--quiet" / -q
Don't output progress messages. Output only error messages.
"--verbose" / -v
Output verbose progress messages.
"--debug" magic / -d magic
Output debug messages, this option may be specified multiple times. magic determines what is output:
magic          remark
script         internal progress messages of driver scripts
keep_tmpfiles  don't discard temporary files
markup         output markup trace, as explained in xindy manual
level=n        log level, n is 0 (default), 1, 2, or 3
"--out-file" outfile.ind / -o outfile.ind
Output index to file outfile.ind. If this option is not passed, the name of the output file is the base name of the first argument and the file extension ind. If the raw index is read from standard input, this option is mandatory.
"--log-file" log.ilg / -t log.ilg
Output log messages to file log.ilg. These log messages are independent from the progress messages that you can influence with "--debug" or "--verbose".
"--language" lang / -L lang
The index is sorted according to the rules of language lang. These rules are encoded in a xindy module created by make-rules.

If no input encoding is specified via "--codepage" or enforced by input markup, a xindy module for that language is searched with a latin, a cp, an iso, ascii, or utf8 encoding, in that order.

"--codepage" enc / -C enc
There are two different situations and use cases for this option.
Input markup is "latex" (the default).

Then texindy's raw input is assumed to be encoded in LaTeX Internal Character Representation (LICR). I.e., non-ASCII characters are encoded as command sequences. This option tells xindy the encoding it shall use for letter group headings. (Additionally it specifies the encoding used internally for sorting -- but that doesn't matter for the result.)

Only LICR encodings for Latin script alphabets are supported; more precisely characters that are in LaTeX latin1, latin2, and latin3 LICR encodings.

Even when you specify "utf8" as codepage, only these characters will be known. But if you use non-Latin alphabets, you probably use (or should use) XeLaTeX or LuaLaTeX and then you have a different input markup.

Input markup is "xelatex" or "omega".

Then this option is ignored; codepage "utf8" is enforced.

texindy's raw input is assumed to be UTF-8 encoded, LICR is not used.

"--module" module / -M module
Load the xindy module module.xdy. This option may be specified multiple times. The modules are searched in the xindy search path that can be changed with the environment variable "XINDY_SEARCHPATH".
"--input-markup" input / -I input
Specifies the input markup of the raw index. Supported values for input are "latex", "xelatex", and "omega".

"latex" input markup is the one that is emitted by default from the LaTeX kernel, or by the "index" macro package of David Jones, when used with standard LaTeX or pdfLaTeX. ^^-notation of single byte characters is supported. Usage of LaTeX's inputenc package is assumed as well, i.e., raw input is encoded in LICR.

"xelatex" input markup is like "latex", but without inputenc usage. Raw input is encoded in UTF-8. LuaLaTeX has the same input markup, there's no special option value for it.

"omega" input markup is like "latex" input markup, but with Omega's ^^-notation as encoding for non-ASCII characters. LICR encoding is not used then, and "utf8" is enforced to be the codepage for sorting and for output of letter group headings.

The following languages are supported:

albanian      gypsy             portuguese
croatian      hausa             romanian
czech         hungarian         russian-iso
danish        icelandic         slovak-small
english       italian           slovak-large
esperanto     kurdish-bedirxan  slovenian
estonian      kurdish-turkish   spanish-modern
finnish       latin             spanish-traditional
french        latvian           swedish
general       lithuanian        turkish
german-din    lower-sorbian     upper-sorbian
german-duden  norwegian         vietnamese
greek-iso     polish

German recognizes two different sorting schemes to handle umlauts: normally, "ae" is sorted like "ae", but in phone books or dictionaries, it is sorted like "a". The first scheme is known as DIN order, the second as Duden order.

"*-iso" language names assume that the raw index entries are in ISO 8859-9 encoding.

"gypsy" is a northern Russian dialect.

belarusian    mongolian         serbian
bulgarian     russian           ukrainian

greek         klingon

This is not yet written. You can look them up in your xindy distribution, in the modules/lang/language/ directory (where language is your language). They are named variant-codepage-lang.xdy, where variant- is most often empty (for german, it's "din5007" and "duden"; for spanish, it's "modern" and "traditional", etc.)

There is a set of texindy standard modules that help to process LaTeX index files. Some of them are automatically loaded. Some of them are loaded by default, this can be turned off with a texindy option. Others may be specified as "--module" argument to achieve a specific effect.

xindy Module    Category  Description

word-order      Default   A space comes before any letter in the
                          alphabet: ``index style'' is listed before
                          ``indexing''. Turn it off with option -l.
letter-order    Add-on    Spaces are ignored: ``index style''
                          is sorted after ``indexing''.
keep-blanks     Add-on    Leading and trailing white space (blanks
                          and tabs) are not ignored; intermediate
                          white space is not changed.
ignore-hyphen   Add-on    Hyphens are ignored:
                          ``ad-hoc'' is sorted as ``adhoc''.
ignore-punctuation Add-on All kinds of punctuation characters are
                          ignored: hyphens, periods, commas, slashes,
                          parentheses, and so on.
numeric-sort    Auto      Numbers are sorted numerically, not like
                          characters: ``V64'' appears before ``V128''.

page-ranges     Default   Appearances on more than two consecutive
                          pages are listed as a range: ``1--4''.
                          Turn it off with option -r.
ff-ranges       Add-on    Uses implicit ``ff'' notation for ranges
                          of three pages, and explicit ranges
                          thereafter: 2f, 2ff, 2--6.
ff-ranges-only  Add-on    Uses only implicit ranges: 2f, 2ff.
book-order      Add-on    Sorts page numbers with common book numbering
                          scheme correctly -- Roman numerals first, then
                          Arabic numbers, then others: i, 1, A.

tex             Auto      Handles basic TeX conventions.
latex-loc-fmts  Auto      Provides LaTeX formatting commands
                          for page number encapsulation.
latex           Auto      Handles LaTeX conventions, both in raw
                          index entries and output markup; implies
makeindex       Auto      Emulates the default MakeIndex input syntax
                          and quoting behavior.
latin-lettergroups Auto   Layout contains a single Latin letter
                          above each group of words starting with the
                          same letter.
german-sty      Add-on    Handles umlaut markup of babel's german
                          and ngerman options.

xindy does not claim to be completely compatible with MakeIndex, that would prevent some of its enhancements. That said, we strive to deliver as much compatibility as possible. The most important incompatibilities are

  • For raw index entries in LaTeX syntax, "\index{aaa|bbb}" is interpreted differently. For MakeIndex "bbb" is markup that is output as a LaTeX tag for this page number. For xindy, this is a location attribute, an abstract identifier that will be later associated with markup that should be output for that attribute.

    For straight-forward usage, when "bbb" is "textbf" or similar, we supply location attribute definitions that mimic MakeIndex's behaviour.

    For more complex usage, when "bbb" is not an identifier, no such compatibility definitions exist and may also not been created with current xindy. Such a situation is reported to exist for the "memoir" LaTeX class.

    Programmers who know Common Lisp and Lex and want to work on a remedy should please contact the author.

  • If you have an index rage and a location attribute, e.g., "\index{key\(attr}" starts the range, one needs (1) to specify that attribute in the range closing entry as well (i.e., as "\index{key\)attr}") and (2) one needs to declare the index attribute in an xindy style file.

    MakeIndex will output the markup "\attr{page1--page2}" for such a construct. This is not possible to achieve in xindy, output will be "\attrMarkup{page1}--\attrMarkup{page2}". (This is actually considered a bug, but not a high priority one.)

    The difference between MakeIndex page number tags and xindy location attributes was already explained in the previous item.

  • The MakeIndex compatibility definitions support only the default raw index syntax and markup definition. It is not possible to configure raw index parsing or use a MakeIndex style file to describe output markup.

This is the name of the xindy module that loads all auto-loaded modules. The default is "texindy".
