\&    device it is about one 750 kB (according to the application manager).
\&
\&    The perlXYZ.sis includes only the Perl DLL: to create an additional
\&    SIS file which includes some of the standard (pure) Perl libraries,
\&    issue the command
\&
\&        make perllib.sis
\&
\&    Some of the standard Perl libraries are included, but not all:
\&    see L</HISTORY> or F<symbian\einstall.cfg> for more details
\&    (250 kB \-> 700 kB).
\&
\&    Some of the standard Perl XS extensions (see L</HISTORY> are
\&    also available:
\&
\&        make perlext.sis
\&
\&    which will create perlXYZext.sis (290 kB \-> 770 kB).
\&
\&    To compile the demonstration application PerlApp you need first to
\&    install the Perl headers under the SDK.
\&
\&    To install the Perl headers and the class CPerlBase documentation
\&    so that you no more need the Perl sources around to compile Perl
\&    applications using the SDK:
\&
\&        make sdkinstall
\&
\&    The destination directory is C:\eSymbian\eperl\eX.Y.Z.  For more
\&    details, see F<symbian\ePerlBase.pod>.
\&
\&    Once the headers have been installed, you can create a SIS for
\&    the PerlApp:
\&
\&        make perlapp.sis
\&
\&    The perlapp.sis (11 kB \-> 16 kB) will be built in the symbian
\&    subdirectory, but a copy will also be made to the main directory.
\&
\&    If you want to package the Perl DLLs (one for WINS, one for ARMI),
\&    the headers, and the documentation:
\&
\&        make perlsdk.zip
\&
\&    which will create perlXYZsdk.zip that can be used in another
\&    Windows system with the SDK, without having to compile Perl in
\&    that system.
\&
\&    If you want to package the PerlApp sources:
\&
\&        make perlapp.zip
\&
\&    If you want to package the perl.exe and miniperl.exe, you
\&    can use the perlexe.sis and miniperlexe.sis make targets.
\&    You also probably want the perllib.sis for the libraries
\&    and maybe even the perlapp.sis for the recognizer.
\&
\&    The make target \*(Aqallsis\*(Aq combines all the above SIS targets.
\&
\&    To clean up after compilation you can use either of
\&
\&        make clean
\&        make distclean
\&
\&    depending on how clean you want to be.

.Sh "PerlApp"
.IX Subsection "PerlApp"
The PerlApp application demonstrates how to embed Perl interpreters
to a Symbian application.  The \*(L"Time\*(R" menu item runs the following
Perl code: \f(CW\*(C`print "Running in ", $^O, "\en", scalar localtime\*(C'\fR,
the \*(L"Oneliner\*(R" allows one to type in Perl code, and the \*(L"Run\*(R"
opens a file chooser for selecting a Perl file to run.
.PP
The PerlApp also is started when the \*(L"Perl recognizer\*(R" (also included
and installed) detects a Perl file being activated througg the \s-1GUI\s0,
and offers either to install it under \ePerl (if the Perl file is in
the inbox of the messaging application) or to run it (if the Perl file
is under \ePerl).
.Sh "sisify.pl"
.IX Subsection "sisify.pl"
In the symbian subdirectory there is sisify.pl utility which can be
used to package Perl scripts and/or Perl library directories into \s-1SIS\s0
files, which can be installed to the device.  To run the sisify.pl
utility, you will need to have the 'makesis' and 'uidcrc' utilities
already installed.  If you don't have the Win32 SDKs, you may try
for example http://gnupoc.sourceforge.net/ or http://symbianos.org/~andreh/.
.Sh "Using Perl in Symbian"
.IX Subsection "Using Perl in Symbian"
First of all note that you have full access to the Symbian device
when using Perl: you can do a lot of damage to your device (like
removing system files) unless you are careful.  Please do take
backups before doing anything.
.PP
The Perl port has been done for the most part using the Symbian
standard POSIX-ish \s-1STDLIB\s0 library. It is a reasonably complete
library, but certain corners of such emulation libraries that tend
to be left unimplemented on non-UNIX platforms have been left
unimplemented also this time: \fIfork()\fR, \fIsignals()\fR, user/group ids,
\&\fIselect()\fR working for sockets, non-blocking sockets, and so forth.
See the file symbian/config.sh and look for 'undef' to find the
unsupported APIs (or from Perl use Config).
.PP
The filesystem of Symbian devices uses DOSish syntax, \*(L"drives\*(R"
separated from paths by a colon, and backslashes for the path.  The
exact assignment of the drives probably varies between platforms, but
for example in Series 60 you might see C: as the (flash) main memory,
D: as the \s-1RAM\s0 drive, E: as the memory card (\s-1MMC\s0), Z: as the \s-1ROM\s0.  In
Series 80 D: is the memory card.  As far the devices go the \s-1NUL:\s0 is
the bit bucket, the COMx: are the serial lines, IRCOMx: are the \s-1IR\s0
ports, \s-1TMP:\s0 might be C:\eSystem\eTemp.  Remember to double those
backslashes in doublequoted strings.
.PP
The Perl \s-1DLL\s0 is installed in \eSystem\eLibs\e.  The Perl libraries and
extension DLLs are installed in \eSystem\eLibs\ePerl\eX.Y.Z\e.  The PerlApp
is installed in \eSystem\eApps\e, and the \s-1SIS\s0 also installs a couple of
demo scripts in \ePerl\e (C:\eMydocs\ePerl\e on Nokia 7710).
.PP
Note that the Symbian filesystem is very picky: it strongly prefers
the \e instead of the /.
.PP
When doing \s-1XS\s0 / Symbian \*(C+ programming include first the Symbian
headers, then any standard C/POSIX headers, then Perl headers, and finally
any application headers.
.PP
\&\fINew()\fR and \fICopy()\fR are unfortunately used by both Symbian and Perl code
so you'll have to play cpp games if you need them.  PerlBase.h undefines
the Perl definitions and redefines them as \fIPerlNew()\fR and \fIPerlCopy()\fR.
.SH "TO DO"
.IX Header "TO DO"
Lots.  See \fIsymbian\eTODO\fR.
.SH "WARNING"
.IX Header "WARNING"
As of Perl Symbian port version 0.4.1 any part of Perl's standard
regression test suite has not been run on a real Symbian device using
the ported Perl, so innumerable bugs may lie in wait.  Therefore there
is absolutely no warranty.
.SH "NOTE"
.IX Header "NOTE"
When creating and extending application programming interfaces (APIs)
for Symbian or Series 60 or Series 80 or Series 90 it is suggested
that trademarks, registered trademarks, or trade names are not used in
the \s-1API\s0 names.  Instead, developers should consider basing the \s-1API\s0
naming in the existing (\*(C+, or maybe Java) public component and \s-1API\s0
naming, modified as appropriate by the rules of the programming
language the new APIs are for.
