It takes a raw index as input, and produces a merged, sorted and tagged index. Merging, sorting, and tagging is controlled by xindy style files. Files with the raw index are passed as arguments. If no arguments are passed, the raw index will be read from standard input. B is completely described in its manual that you will find on its Web Site, http://www.xindy.org/. A good introductionary description appears in the indexing chapter of the LaTeX Companion (2nd ed.) If you want to produce an index for LaTeX documents, the command texindy(1) is probably more of interest for you. It is a wrapper for B that turns on many LaTeX conventions by default. =head1 OPTIONS =over =item C<--version> / B<-V> output version numbers of all relevant components and exit. =item C<--help> / B<-h> / B<-?> output usage message with options explanation. =item C<--quiet> / B<-q> Don't output progress messages. Output only error messages. =item C<--verbose> / B<-v> Output verbose progress messages. =item C<--debug> I / B<-d> I Output debug messages, this option may be specified multiple times. I 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 =item C<--out-file> F / B<-o> F Output index to file F. If this option is not passed, the name of the output file is the base name of the first argument and the file extension F. If the raw index is read from standard input, this option is mandatory. =item C<--log-file> F / B<-t> F Output log messages to file F. These log messages are independent from the progress messages that you can influence with C<--debug> or C<--verbose>. =item C<--language> I / B<-L> I The index is sorted according to the rules of language I. These rules are encoded in a xindy module created by I. If no input encoding is specified via C<--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. Language modules are either placed in the F or in the F sub-directory of the modules base directory. =item C<--codepage> I / B<-C> I The raw input is in input encoding I. This information is used to select the correct xindy sort module and output encoding of letter group headings. When C or C input markup is used, C is always used as codepage, then this option is ignored. If raw input is in LICR, texindy(1) should be used instead of xindy(1). It will activate a mapping of I encoding for C input markup to the chosen raw input codepage. =item C<--module> I / B<-M> I Load the xindy module F. This option may be specified multiple times. The modules are searched in the xindy search path that can be changed with the environment variable C. =item C<--input-markup> I / B<-I> I Specifies the input markup of the raw index. Supported values for I are C, C, C, and C. C and C input markup is the one that is emitted by default from the LaTeX kernel, or by the C macro package of David Jones. ^^-notation of single byte characters is supported. Remapping of LICR-encoded characters is not done; use texindy(1) for that. Use input markup C if you use standard LaTeX or pdfLaTeX and use input markup C if you use XeLaTeX or LuaLaTeX. C input markup is like C input markup, but with Omega's ^^-notation as encoding for non-ASCII characters. C input markup is specified in the xindy manual. =item C<--interactive> Start xindy in interactive mode. You will be in a xindy read-eval-loop where xindy language expressions are read and evaluated interactively. =item C<--mem-file> I This option is only usable for developers or in very rare situations. The compiled xindy kernel is stored in a so-called I, canonically named F, and located in the xindy library directory. This option allows to use another xindy kernel. =back =head1 SUPPORTED LANGUAGES / CODEPAGES The following languages are supported: =head2 Latin scripts 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, C<ä> is sorted like C, but in phone books or dictionaries, it is sorted like C. The first scheme is known as I, the second as I. C<*-iso> language names assume that the raw index entries are in ISO 8859-9 encoding. C is a northern Russian dialect. =head2 Cyrillic scripts belarusian mongolian serbian bulgarian russian ukrainian macedonian =head2 Other scripts greek klingon =head2 Available Codepages This is not yet written. You can look them up in your xindy distribution, in the F directory (where I is your language). They are named F, where F is most often empty (for german, it's C and C; for spanish, it's C and C, etc.) < Describe available codepages for each language > < Describe relevance of codepages (as internal representation) for LaTeX inputenc > =head1 ENVIRONMENT =over =item C A list of directories where the xindy modules are searched in. No subtree searching is done (as in TDS-conformant TeX). If this environment variable is not set, the default is used: C<.:>IC<:>IC. I is determined at run time, relative to the B command location: Either it's F<../modules>, that's the case for F-installations. Or it's F<../lib/xindy/modules>, that's the case for F-installations. =item C Library directory where F is located. The modules directory may be a subdirectory, too. =back =head1 COMPATIBILITY TO MAKEINDEX B 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 =over =item * For raw index entries in LaTeX syntax, C<\index{aaa|bbb}> is interpreted differently. For MakeIndex C is markup that is output as a LaTeX tag for this page number. For B, 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 C is C or similar, we supply location attribute definitions that mimic MakeIndex's behaviour. For more complex usage, when C is not an identifier, no such compatibility definitions exist and may also not been created with current B. In particular, this means that by default the LaTeX package C will create raw index files that cannot be processed with B. This is not a bug, this is the unfortunate result of an intented incompatibility. It is currently not possible to get both hyperref's index links and use B. A similar situation is reported to exist for the C LaTeX class. Programmers who know Common Lisp and Lex and want to work on a remedy should please contact the author. =item * If you have an index rage and a location attribute, e.g., C<\index{key\(attr}> starts the range, one needs (1) to specify that attribute in the range closing entry as well (i.e., as C<\index{key\)attr}>) and (2) one needs to declare the index attribute in an B style file. MakeIndex will output the markup C<\attr{page1--page2}> for such a construct. This is not possible to achieve in B, output will be C<\attrMarkup{page1}--\attrMarkup{page2}>. (This is actually considered a bug, but not a high priority one.) The difference between MakeIndex page number tags and B location attributes was already explained in the previous item. =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. =back =head1 KNOWN ISSUES Option B<-q> also prevents output of error messages. Error messages should be output on stderr, progress messages on stdout. There should be a way to output the final index to stdout. This would imply B<-q>, of course. LaTeX raw index parsing should be configurable. Codepage C should be supported for all languages, and should be used as internal codepage for LaTeX inputenc re-encoding. =head1 SEE ALSO texindy(1), tex2xindy(1) =head1 AUTHOR Joachim Schrod =head1 LEGALESE Copyright (c) 2004-2014 by Joachim Schrod.
