<h4 class="subsection">22.5.4 Other Customization Variables</h4>

<p>This table gives the remaining customization variables, which apply to
multiple formats, or affect global behavior, or otherwise don&rsquo;t fit
into the categories of the previous sections.
</p>
<dl compact="compact">
<dt><code>CLOSE_QUOTE_SYMBOL</code>
<a name="index-CLOSE_005fQUOTE_005fSYMBOL"></a>
</dt>
<dd><p>When a closing quote is needed, use this character; default <code>&amp;rsquo;</code>
in HTML, <code>&amp;#8217;</code> in Docbook.  The default for Info is the same
as <code>OPEN_QUOTE_SYMBOL</code> (see below).
</p>

</dd>
<dt><code>CPP_LINE_DIRECTIVES</code>
<a name="index-CPP_005fLINE_005fDIRECTIVES-1"></a>
</dt>
<dd><p>Recognize <code>#line</code> directives in a &ldquo;preprocessing&rdquo; pass
(see <a href="External-Macro-Processors.html#External-Macro-Processors">External Macro Processors</a>); on by default.
</p>
</dd>
<dt><code>DEBUG</code>
<a name="index-DEBUG"></a>
</dt>
<dd><p>If set, debugging output is generated; default is off (zero).
</p>
</dd>
<dt><code>DOCTYPE</code>
<a name="index-DOCTYPE"></a>
</dt>
<dd><a name="index-SystemLiteral"></a>
<p>For Docbook, HTML, XML.  Specifies the <code>SystemLiteral</code>, the
entity&rsquo;s system identifier.  This is a URI which may be used to
retrieve the entity, and identifies the canonical DTD for the
document.  The default value is different for each of HTML, Docbook
and Texinfo&nbsp;XML.
</p>
</dd>
<dt><code>DUMP_TEXI</code>
<a name="index-DUMP_005fTEXI"></a>
</dt>
<dd><p>For debugging.  If set, no conversion is done, only parsing and macro
expansion.  If the option <samp>--macro-expand</samp> is set, the Texinfo
source is also expanded to the corresponding file.  Default false.
</p>
</dd>
<dt><code>DUMP_TREE</code>
<a name="index-DUMP_005fTREE"></a>
</dt>
<dd><p>For debugging.  If set, the tree constructed upon parsing a Texinfo
document is output to standard error; default false.
</p>
</dd>
<dt><code>ENABLE_ENCODING_USE_ENTITY</code>
<a name="index-ENABLE_005fENCODING_005fUSE_005fENTITY"></a>
</dt>
<dd><p>For HTML, XML.  If <samp>--enable-encoding</samp> is set, and there is an
entity corresponding with the letter or the symbol being output,
prefer the entity.  Set by default for HTML, but not XML.
</p>
</dd>
<dt><code>EXTERNAL_CROSSREF_SPLIT</code>
<a name="index-EXTERNAL_005fCROSSREF_005fSPLIT"></a>
</dt>
<dd><p>For cross references to other manuals, this determines if the other
manual is considered to be split or monolithic.  By default, it is set
based on the value of <code>SPLIT</code>.  See <a href="HTML-Xref.html#HTML-Xref">HTML Xref</a>, and see <a href="HTML-Xref-Configuration.html#HTML-Xref-Configuration">HTML Xref Configuration</a>.
</p>
</dd>
<dt><code>EXTENSION</code>
<a name="index-EXTENSION"></a>
</dt>
<dd><p>The extension added to the output file name.  The default is different
for each output format.
</p>
</dd>
<dt><code>FIX_TEXINFO</code>
<a name="index-FIX_005fTEXINFO"></a>
</dt>
<dd><p>For &ldquo;plain Texinfo&rdquo; (see the <code>PLAINTEXINFO</code> item).  If set to
false, the resulting Texinfo does not have all errors corrected, such
as missing &lsquo;<samp>@end</samp>&rsquo;; default true.  This variable is only
relevant when expanding Texinfo; other converters always try to
output something sane even if the input is erroneous.
</p>

</dd>
<dt><code>IGNORE_BEFORE_SETFILENAME</code>
<a name="index-IGNORE_005fBEFORE_005fSETFILENAME"></a>
</dt>
<dd><p>If set, begin outputting at <code>@setfilename</code>, if
<code>@setfilename</code> is present; default true.
</p>
</dd>
<dt><code>IGNORE_SPACE_AFTER_BRACED_COMMAND_NAME</code>
<a name="index-IGNORE_005fSPACE_005fAFTER_005fBRACED_005fCOMMAND_005fNAME"></a>
</dt>
<dd><p>If set, spaces are ignored after an @-command that takes braces.
Default true, matching the TeX behavior.
</p>
</dd>
<dt><code>INDEX_ENTRY_COLON</code>
<a name="index-INDEX_005fENTRY_005fCOLON"></a>
</dt>
<dd><p>Symbol used between the index entry and the associated node or section;
default &lsquo;<samp>:</samp>&rsquo;.
</p>
</dd>
<dt><code>INFO_SPECIAL_CHARS_WARNING</code>
<a name="index-INFO_005fSPECIAL_005fCHARS_005fWARNING"></a>
</dt>
<dd><p>If set, warn about problematic constructs for Info output (such as the
string &lsquo;<samp>::</samp>&rsquo;) in node names, menu items, and cross references;
default true.  Do not warn about index entries, since parsing problems
there don&rsquo;t prevent navigation; readers can still relatively easily
find their way to the node in question.
</p>
</dd>
<dt><code>INLINE_INSERTCOPYING</code>
<a name="index-INLINE_005fINSERTCOPYING"></a>
</dt>
<dd><p>If set, <code>@insertcopying</code> is replaced by the <code>@copying</code>
content (see <a href="_0040copying.html#g_t_0040copying"><tt>@copying</tt></a>) as if <code>@insertcopying</code> were a
user-defined macro; default false.
</p>
</dd>
<dt><code>INPUT_ENCODING_NAME</code>
<a name="index-INPUT_005fENCODING_005fNAME"></a>
</dt>
<dd><p>Normalized encoding name suitable for output.  Should be a usable
charset name in HTML, typically one of the preferred IANA encoding
names.  You should not need to use this variable, since it is set by
<code>@documentencoding</code> (see <a href="_0040documentencoding.html#g_t_0040documentencoding"><tt>@documentencoding</tt></a>).
</p>
</dd>
<dt><code>INPUT_PERL_ENCODING</code>
<a name="index-INPUT_005fPERL_005fENCODING"></a>
</dt>
<dd><p>Perl encoding used to process the Texinfo source.  You should not need
to use that variable, since it is set by <code>@documentencoding</code>
(see <a href="_0040documentencoding.html#g_t_0040documentencoding"><tt>@documentencoding</tt></a>).
</p>
</dd>
<dt><code>MACRO_BODY_IGNORES_LEADING_SPACE</code>
<a name="index-MACRO_005fBODY_005fIGNORES_005fLEADING_005fSPACE"></a>
</dt>
<dd><p>Ignore white space at the beginning of user defined macro body line,
mimicking a TeX limitation (see <a href="Macro-Details.html#Macro-Details">Macro Details</a>).  Default off.
</p>
</dd>
<dt><code>MAX_MACRO_CALL_NESTING</code>
<a name="index-MAX_005fMACRO_005fCALL_005fNESTING"></a>
</dt>
<dd><p>The maximal number of recursive calls of @-commands defined through
<code>@rmacro</code>; default 100000.  The purpose of this variable is to
avoid infinite recursions.
</p>
</dd>
<dt><code>MENU_ENTRY_COLON</code>
<a name="index-MENU_005fENTRY_005fCOLON"></a>
</dt>
<dd><p>Symbol used between the menu entry and the description; default
&lsquo;<samp>:</samp>&rsquo;.
</p>
</dd>
<dt><code>NO_USE_SETFILENAME</code>
<a name="index-NO_005fUSE_005fSETFILENAME"></a>
</dt>
<dd><p>If set, do not use <code>@setfilename</code> to set the document name;
instead, base the output document name only on the input file name.
The default is false.
</p>
</dd>
<dt><code>NODE_FILENAMES</code>
<a name="index-NODE_005fFILENAMES"></a>
</dt>
<dd><p>If set, node names are used to construct file names.  By default, it
is set if the output is split by node, or if <code>NODE_FILES</code> is set
and the output is split in any way.
</p>
</dd>
<dt><code>NODE_NAME_IN_INDEX</code>
<a name="index-NODE_005fNAME_005fIN_005fINDEX"></a>
</dt>
<dd><p>If set, use node names in index entries, otherwise prefer section names;
default true.
</p>
</dd>
<dt><code>NODE_NAME_IN_MENU</code>
<a name="index-NODE_005fNAME_005fIN_005fMENU"></a>
</dt>
<dd><p>If set, use node names in menu entries, otherwise prefer section names;
default true.
</p>
</dd>
<dt><code>OPEN_QUOTE_SYMBOL</code>
<a name="index-OPEN_005fQUOTE_005fSYMBOL"></a>
</dt>
<dd><p>When an opening quote is needed, e.g., for &lsquo;<samp>@samp</samp>&rsquo; output, use
the specified character; default <code>&amp;lsquo;</code> for HTML,
<code>&amp;#8216;</code> for Docbook.  For Info, the default depends on the
enabled document encoding (see <a href="_0040documentencoding.html#g_t_0040documentencoding"><tt>@documentencoding</tt></a>); if no
document encoding is set, or the encoding is US-ASCII, etc., &lsquo;<samp>'</samp>&rsquo;
is used.  This character usually appears as an undirected single quote
on modern systems.  If the document encoding is Unicode, the Info
output uses a Unicode left quote.
</p>
</dd>
<dt><code>OUTPUT_ENCODING_NAME</code>
<a name="index-OUTPUT_005fENCODING_005fNAME"></a>
</dt>
<dd><p>Normalized encoding name used for output files.  Should be a usable
charset name in HTML, typically one of the preferred IANA encoding
names.  By default, if an input encoding is set (typically through
<code>@documentencoding</code> or <code>INPUT_ENCODING_NAME</code>), this
information is used to set the output encoding name.  If no input
encoding is specified, the default output encoding name may be set by
the output format.  In particular, the XML-based formats use
<code>utf-8</code> for <code>OUTPUT_ENCODING_NAME</code> if the encoding is not
otherwise specified.  See <a href="_0040documentencoding.html#g_t_0040documentencoding"><tt>@documentencoding</tt></a>.
</p>
</dd>
<dt><code>OVERVIEW_LINK_TO_TOC</code>
<a name="index-OVERVIEW_005fLINK_005fTO_005fTOC"></a>
</dt>
<dd><p>If set, the cross references in the Overview link to the corresponding
Table of Contents entries; default true.
</p>
</dd>
<dt><code>PACKAGE</code>

</dt>
<dt><code>PACKAGE_VERSION</code>
<a name="index-PACKAGE_005fVERSION"></a>
</dt>
<dt><code>PACKAGE_AND_VERSION</code>
<a name="index-PACKAGE_005fAND_005fVERSION"></a>
</dt>
<dt><code>PACKAGE_URL</code>
<a name="index-PACKAGE_005fURL"></a>
</dt>
<dt><code>PACKAGE_NAME</code>
<a name="index-PACKAGE_005fNAME"></a>
</dt>
<dd><p>The implementation&rsquo;s short package name, package version, package name
and version concatenated, package url, and full package name,
respectively.  By default, these variables are all set through
Autoconf, Automake, and <code>configure</code>.
</p>
</dd>
<dt><code>PREFIX</code>
<a name="index-PREFIX"></a>
</dt>
<dd><p>The output file prefix, which is prepended to some output file names.
By default it is set by <code>@setfilename</code> or from the input file
(see <a href="_0040setfilename.html#g_t_0040setfilename"><tt>@setfilename</tt></a>).  How this value is used depends on the
value of other customization variables or command line options, such
as whether the output is split and <code>NODE_FILENAMES</code>.  The default
is unset.
</p>
</dd>
<dt><code>PROGRAM</code>
<a name="index-PROGRAM"></a>
</dt>
<dd><p>Name of the program used.  By default, it is set to the name of the
program launched, with a trailing &lsquo;<samp>.pl</samp>&rsquo; removed.
</p>
</dd>
<dt><code>RENAMED_NODES_FILE</code>
<a name="index-RENAMED_005fNODES_005fFILE"></a>
</dt>
<dd><p>If set, use the value for the renamed nodes description file.  If not
set, the file is <samp><var>doc_basename</var>-noderename.cnf</samp>.
See <a href="HTML-Xref-Link-Preservation.html#HTML-Xref-Link-Preservation">HTML Xref Link Preservation</a>.
</p>
</dd>
<dt><code>RENAMED_NODES_REDIRECTIONS</code>
<a name="index-RENAMED_005fNODES_005fREDIRECTIONS"></a>
</dt>
<dd><p>If set, create redirection files for renamed nodes.  Set by default
when generating HTML.
</p>
</dd>
<dt><code>SHOW_MENU</code>
<a name="index-SHOW_005fMENU-1"></a>
</dt>
<dd><a name="index-_002d_002dno_002dheaders-1"></a>
<p>If set, Texinfo menus are output.  By default, it is set unless
generating Docbook or if <samp>--no-headers</samp> is specified.
</p>
</dd>
<dt><code>SORT_ELEMENT_COUNT</code>
<a name="index-SORT_005fELEMENT_005fCOUNT"></a>
</dt>

<a name="index-Longest-nodes_002c-finding"></a>
<a name="index-Sorting-nodes-by-size"></a>
<p>If set, the name of a file to which a list of elements (nodes or
sections, depending on the output format) is dumped, sorted by the
number of lines they contain after removal of @-commands; default
unset.  This is used by the program <code>texi-elements-by-size</code> in
the <samp>util/</samp> directory of the Texinfo source distribution
(see <a href="Tips.html#texi_002delements_002dby_002dsize">texi-elements-by-size</a>).
</p>

<dt><code>SORT_ELEMENT_COUNT_WORDS</code>
<a name="index-SORT_005fELEMENT_005fCOUNT_005fWORDS"></a>
</dt>
<dd><p>When dumping the elements-by-size file (see preceding item), use word
counts instead of line counts; default false.
</p>

</dd>
<dt><code>TEST</code>
<a name="index-TEST"></a>
</dt>
<dd><p>If set to true, some variables which are normally dynamically
generated anew for each run (date, program name, version) are set to
fixed and given values.  This is useful to compare the output to a
reference file, as is done for the tests.  The default is false.
</p>
</dd>
<dt><code>TEXI2DVI</code>
<a name="index-TEXI2DVI"></a>
</dt>

</dd>
<dt><code>TEXINFO_COLUMN_FOR_DESCRIPTION</code>
<a name="index-TEXINFO_005fCOLUMN_005fFOR_005fDESCRIPTION"></a>
</dt>
<dd><p>Used with the <code>indent_menu_descriptions</code> tree transformation,
described below; default 32 (matching
<code>texinfo-column-for-description</code> in Emacs)).
</p>
</dd>
<dt><code>TEXINFO_DTD_VERSION</code>
<a name="index-TEXINFO_005fDTD_005fVERSION"></a>
</dt>
<dd><p>For XML.  Version of the DTD used in the XML output preamble.  The
default is set based on a variable in <samp>configure.ac</samp>.
</p>
</dd>
<dt><code>TEXTCONTENT_COMMENT</code>
<a name="index-TEXTCONTENT_005fCOMMENT"></a>
</dt>
<dd><p>For stripped text content output (i.e., when
<code>TEXINFO_OUTPUT_FORMAT</code> is set to <code>textcontent</code>).  If set,
also output comments.  Default false.
</p>
</dd>
<dt><code>TOP_NODE_UP</code>
<a name="index-TOP_005fNODE_005fUP"></a>
</dt>
<dd><p>Up node for the Top node; default &lsquo;<samp>(dir)</samp>&rsquo;.
</p>
</dd>
<dt><code>TREE_TRANSFORMATIONS</code>
<a name="index-TREE_005fTRANSFORMATIONS"></a>
</dt>
<dd><p>The associated value is a comma separated list of transformations that
can be applied to the Texinfo tree prior to outputting the result.  If
more than one is specified, the ordering is irrelevant; each is always
applied at the necessary point during processing.
</p>
<p>The only one executed by default is
&lsquo;<samp>move_index_entries_after_items</samp>&rsquo; for HTML and Docbook output.
Here&rsquo;s an example of updating the master menu in a document:
</p>
<div class="example">
<pre class="example">makeinfo \
  -c TREE_TRANSFORMATIONS=regenerate_master_menu \
  -c PLAINTEXINFO=1 \
  mydoc.texi \
  -o /tmp/out
</pre></div>

<p>(Caveat: Since <code>PLAINTEXINFO</code> output does expand
Texinfo macros and conditionals, it&rsquo;s necessary to remove any such
differences before installing the updates in the original document.
This will be remedied in a future release.)
</p>
<p>The following transformations are currently supported (many are used
in the <code>pod2texi</code> utility distributed with Texinfo;
see <a href="Invoking-pod2texi.html#Invoking-pod2texi">Invoking <tt>pod2texi</tt></a>):
</p>

</dt>
<dd><p>Adds empty <code>@unnumbered...</code> sections in a tree to fill gaps in
sectioning.  For example, an <code>@unnumberedsec</code> will be inserted
if an <code>@chapter</code> is followed by an <code>@subsection</code>.
</p>
</dd>
<dt>&lsquo;<samp>indent_menu_descriptions</samp>&rsquo;
<a name="index-indent_005fmenu_005fdescriptions"></a>
</dt>

</dd>
<dt>&lsquo;<samp>move_index_entries_after_items</samp>&rsquo;
<a name="index-move_005findex_005fentries_005fafter_005fitems"></a>
</dt>
<dd><p>In <code>@enumerate</code> and <code>@itemize</code>, move index entries
appearing just before an <code>@item</code> to just after the

<a name="index-simple_005fmenu"></a>
</dt>
<dd><p>Mostly the same as <code>SIMPLE_MENU</code>: use a simple preformatted style
for the menu.  It differs from setting <code>SIMPLE_MENU</code> in that
<code>SIMPLE_MENU</code> only has an effect in HTML output.

</dd>
</dl>

</dd>
<dt><code>USE_NODES</code>
<a name="index-USE_005fNODES"></a>
