Support</a></h1>
<p>Vile supports the use of Perl as an extension language by
embedding a Perl interpreter into the editor.</p>
<p>The "--with-perl" configure option enables Perl support at
build time on Unix hosts (for Win32 instructions see the file
README.PC).</p>
<p>After the executable is successfully built, up to date
documentation for the API in various formats may be obtained from
the following make targets (not built by default):</p>
<pre>
vile-perl-api.doc (unix and win32)
vile-perl-api.man (unix hosts only)
vile-perl-api.html (unix hosts only)
</pre>
<p>A recent version of Perl is required. The interface was
developed and tested using 5.004_04. The most recent version of
Perl may be retrieved from the URL:</p>
<pre>
<a href=
"http://www.perl.com/CPAN/src/latest.tar.gz">http://www.perl.com/CPAN/src/latest.tar.gz</a>
</pre>
<p>The Perl interpreter requires subsidiary files, the location
of which is coded into the Perl library. As such, if a
Perl-enabled Vile binary is to be installed onto multiple
machines, the same version of Perl must be installed on each
target machine, in the same location.</p>
<p>This also means that if a newer version of Perl is installed,
Vile must either be rebuilt against the new version, or the
version-specific directory (given by "perl -V:archlib") of the
old version must be retained.</p>
<p>Note also that embedding a Perl interpreter into Vile will
increase the size of the binary. On many platforms, a shared Perl
library may be built which, at the cost of a load-time
performance penalty, can substantially reduce the size of the
compiled vile, xvile, [nvi, apache, etc, ...] and of course perl
binaries.</p>
<p>See also the output of "perl -V:useshrplib" and the section
"Building a shared libperl.so Perl library" in the "INSTALL" file
from the Perl distribution.</p>

<p>The Perl interface for vile was originally written by Kevin
Buettner in 1997 and 1998.</p>
