<h5 class="subsubsection">6.3.7.2 Man Page Generation</h5>
|
|
|
|
<p>Because of user demand, in addition to full Texinfo manuals, man pages
|
|
are provided which contain extracts from those manuals. These man
|
|
pages are generated from the Texinfo manuals using
|
|
<samp><span class="file">contrib/texi2pod.pl</span></samp> and <samp><span class="command">pod2man</span></samp>. (The man page for
|
|
<samp><span class="command">g++</span></samp>, <samp><span class="file">cp/g++.1</span></samp>, just contains a ‘<samp><span class="samp">.so</span></samp>’ reference
|
|
to <samp><span class="file">gcc.1</span></samp>, but all the other man pages are generated from
|
|
Texinfo manuals.)
|
|
|
|
<p>Because many systems may not have the necessary tools installed to
|
|
generate the man pages, they are only generated if the
|
|
<samp><span class="file">configure</span></samp> script detects that recent enough tools are
|
|
installed, and the Makefiles allow generating man pages to fail
|
|
without aborting the build. Man pages are also included in release
|
|
distributions. They are generated in the source directory.
|
|
|
|
<p>Magic comments in Texinfo files starting ‘<samp><span class="samp">@c man</span></samp>’ control what
|
|
parts of a Texinfo file go into a man page. Only a subset of Texinfo
|
|
is supported by <samp><span class="file">texi2pod.pl</span></samp>, and it may be necessary to add
|
|
support for more Texinfo features to this script when generating new
|
|
man pages. To improve the man page output, some special Texinfo
|
|
macros are provided in <samp><span class="file">doc/include/gcc-common.texi</span></samp> which
|
|
<samp><span class="file">texi2pod.pl</span></samp> understands:
|
|
|
|
<dl>
|
|
<dt><code>@gcctabopt</code><dd>Use in the form ‘<samp><span class="samp">@table @gcctabopt</span></samp>’ for tables of options,
|
|
where for printed output the effect of ‘<samp><span class="samp">@code</span></samp>’ is better than
|
|
that of ‘<samp><span class="samp">@option</span></samp>’ but for man page output a different effect is
|
|
wanted.
|
|
<br><dt><code>@gccoptlist</code><dd>Use for summary lists of options in manuals.
|
|
<br><dt><code>@gol</code><dd>Use at the end of each line inside ‘<samp><span class="samp">@gccoptlist</span></samp>’. This is
|
|
necessary to avoid problems with differences in how the
|
|
‘<samp><span class="samp">@gccoptlist</span></samp>’ macro is handled by different Texinfo formatters.
|
|
</dl>
|
|
|
|
<p>FIXME: describe the <samp><span class="file">texi2pod.pl</span></samp> input language and magic
|
|
comments in more detail.
