texi2any ¶texi2any also reads the environment variable
TEXINFO_OUTPUT_FORMAT to determine the output format, if not
overridden by a command line option. The value should be one of:
docbook dvi dvipdf epub3 html info latex pdf plaintext ps xml
If not set or otherwise specified, Info output is the default.
TEXINFO_OUTPUT_FORMAT may take some other special values, which do
not correspond to any command-line settable output format
(see Customization Variables and Options).
The customization variable of the same name is also read; if set, that overrides an environment variable setting, but not a command-line option. See Customization Variables and Options.
You can control texi2any’s use of Perl extension modules
by setting the TEXINFO_XS environment variable. These modules
are compiled native code that the interpreted Perl code can use.
Ideally, these extension modules should just work, and the only noticeable
difference they should make is that texi2any finishes running
sooner. However, you can use this environment variable for the purposes
of troubleshooting: for example, if you have problems with the output of
texi2any varying depending on whether the extension modules are
in use.
The following values of TEXINFO_XS are recognized by
texi2any:
The default behavior. Try to load extension modules, and silently fall back to the interpreted Perl implementations if this fails.
Try to load extension modules, and if this fails, give a warning message before falling back to the interpreted Perl implementations.
Try to load extension modules, printing many messages while doing so.
Do not use extension modules.
Set TEXINFO_XS_PARSER to ‘0’ to disable the use of the
native code implementation of the parser module. This is the part of
texi2any that converts Texinfo input into an internal tree
format used for further processing into output formats. This may
be useful for working around bugs or incompatibilities between the
native code implementation and the implementation in pure Perl code.
