NAME

db2x_texixml - Make Texinfo files from Tex-XML

SYNOPSIS

db2x_texixml [options]... [xm-document]

DESCRIPTION

db2x_texixml converts a Tex-XML document into one or more Texinfo documents.

If xm-document is not given, then the document to convert comes from standard input.

The filenames of the Texinfo documents are determined by markup in the Tex-XML source. (If the filenames are not specified in the markup, then db2x_texixml attempts to deduce them from the name of the input file. However, the Tex-XML source should specify the filename, because it does not work when there are multiple output files or when the Tex-XML source comes from standard input.)

OPTIONS

--encoding=encoding

Select the character encoding used for the output files. The available encodings are those of iconv(1). The default encoding is us-ascii.

The XML source may contain characters that are not representable in the encoding that you select; in this case the program will bomb out during processing, and you should choose another encoding. (This is guaranteed not to happen with any Unicode encoding such as UT-8, but unfortunately not everyone is able to process Unicode texts.)

If you are using GNUcqs version of iconv(1), you can affix //TRANSLIT to the end of the encoding name to attempt transliterations of any unconvertible characters in the output. Beware, however, that the really inconvertible characters will be turned into another of those damned question marks. (Arencqt you sick of this?)

The suffix //TRANSLIT applied to a Unicode encoding - in particular, utf-8//TRANSLIT - means that the output files are to remain in Unicode, but marku-level character translations using utf8trans are still to be done. So in most cases, an Englis-language document, converted using --encoding=utf-8//TRANSLIT will actually end up as a U-ASCII document, but any untranslatable characters will remain as UT-8 without any warning whatsoever. (Note: strictly speaking this is not lqtransliterationrq.) This method of conversion is a compromise over strict --encoding=us-ascii processing, which aborts if any untranslatable characters are encountered.

Note that man pages and Texinfo documents in no-ASCII encodings (including UT-8) may not be portable to older (no-internationalized) systems, which is why the default value for this option is us-ascii.

To suppress any automatic character mapping or encoding conversion whatsoever, pass the option --encoding=utf-8.

--list-files

Write a list of all the output files to standard output, in addition to normal processing.

--output-dir=dir

Specify the directory where the output files are placed. The default is the current working directory.

This option is ignored if the output is to be written to standard output (triggered by the option --to-stdout).

--to-stdout

Write the output to standard output instead of to individual files.

If this option is used even when there are supposed to be multiple output documents, then everything is concatenated to standard output. But beware that most other programs will not accept this concatenated output.

This option is incompatible with --list-files, obviously.

--info

Pipe the Texinfo output to makeinfo(1), creating Info files directly instead of Texinfo files.

--plaintext

Pipe the Texinfo output to makeinfo --no-headers, thereby creating plain text files.

--help

Show brief usage information and exit.

--version

Show version and exit.

This program uses certain other programs for its operation. If they are not in their default installed locations, then use the following options to set their location:

--utf8trans-program=path, --utf8trans-map=charmap: Use the character map charmap with the utf8trans(1) program, included with docbook2X, found under path.
--iconv-program=path: The location of the iconv(1) program, used for encoding conversions.

NOTES

Texinfo language compatibility. The Texinfo files generated by db2x_texixml sometimes require Texinfo version 4.7 (the latest version) to work properly. In particular:

*: db2x_texixml relies on makeinfo to automatically add punctuation after a @ref if it it not already there. Otherwise the hyperlink will not work in the Info reader (although makeinfo will not emit any error).
*: The new @comma{} command is used for commas (,) occurring inside argument lists to Texinfo commands, to disambiguate it from the comma used to separate different arguments. The only alternative otherwise would be to translate , to . which is obviously undesirable (but earlier docbook2X versions did this).
If you cannot use version 4.7 of makeinfo, you can still use a sed script to perform manually the procedure just outlined.

Relation of Tex-XML with the XML output format of makeinfo. The Tex-XML format used by docbook2X is different and incompatible with the XML format generated by makeinfo(1) with its --xml option. This situation arose partly because the Tex-XML format of docbook2X was designed and implemented independently before the appearance of makeinfocqs XML format. Also Tex-XML is very much geared towards being machin-generated from other XML formats, while there seems to be no no-trivial applications of makeinfocqs XML format. So there is no reason at this point for docbook2X to adopt makeinfocqs XML format in lieu of Tex-XML.

BUGS

*: Text wrapping in menus is utterly broken for no-ASCII text. It is probably also broken everywhere else in the output, but that would be makeinfocqs fault.
*: --list-files might not work correctly with --info. Specifically, when the output Info file get too big, makeinfo will decide to split it into parts named abc.info-1, abc.info-2, abc.info-3, etc. db2x_texixml does not know exactly how many of these files there are, though you can just do an ls to find out.
