.IX Title "TEX2XINDY 1"
.TH TEX2XINDY 1 "2006-07-30" "Version 1.21" "xindy"
.SH "NAME"
tex2xindy \- a preprocessor of the xindy index processor
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& tex2xindy [\-o] [attr_file]
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBtex2xindy\fR transforms a LaTeX index file \f(CW\*(C`.idx\*(C'\fR (or an \f(CW\*(C`.aux\*(C'\fR
file) into a \fBxindy\fR raw index file.
.PP
It is a filter that reads from \fIstdin\fR a file in the input format of
LaTeX's raw index file, i.e., with \f(CW\*(C`\eindexentry\*(C'\fR tags. It outputs on
\&\fIstdout\fR a \fBxindy\fR raw index file, i.e., with \f(CW\*(C`indexentry\*(C'\fR clauses.
.PP
If the option \fB\-o\fR is not specified, \fBtex2xindy\fR handles ^^\-notation
of TeX and outputs the octet that is represented: \f(CW\*(C`^^ab\*(C'\fR in the input
gets output as the octet 0xab. If \f(CW\*(C`^^^^abcd\*(C'\fR or \f(CW\*(C`^^^^^^^^abcdefab\*(C'\fR
are detected, they are output as is.
.PP
If the option \fB\-o\fR is specified, \fBtex2xindy\fR operates in \fIOmega
mode\fR and handles its ^^\-notation: Then \f(CW\*(C`^^ab\*(C'\fR, \f(CW\*(C`^^^^abcd\*(C'\fR, and
\&\f(CW\*(C`^^^^^^^^abcdefab\*(C'\fR represent Unicode characters with code points
0xab, 0xabcd, and 0xabcdefab respectively. They are output in \s-1UTF\-8\s0
encoding.
.PP
If the optional argument \fIattr_file\fR is specified, \fBtex2xindy\fR
writes all index key attributes into this file.
.SH "DEFICITS"
.IX Header "DEFICITS"
This program was written since it was not easily possible to extract
the parser from the old makeindex system. Therefore it does not find
all errors in the input as the \fImakeindex\fR\|(1) version.
.PP
Additionally it uses only the default input specifiers of
\&\fImakeindex\fR\|(1). If other input specifiers (cf. manual page of
\&\fImakeindex\fR\|(1)) are needed, the input specifiers (starting from the
pattern \f(CW\*(C`KEYWORD\*(C'\fR, see below) must be changed and the program must be
recompiled.
.PP
The particular missing feature is configuration of the quote and the
actual characters, maybe also the escape, subitem (level), and encap
characters. Argument and range delimiters seem to be less of a problem.
.PP
In fact, input markup handling (and thus \fBtex2xindy\fR) should be
incorporated into the \fBxindy\fR kernel, to be able to specify
configuration in xindy style files.
