-=head1 NAME
-
-perlplan9 - Plan 9-specific documentation for Perl
-
-=head1 DESCRIPTION
-
-These are a few notes describing features peculiar to
-Plan 9 Perl. As such, it is not intended to be a replacement
-for the rest of the Perl 5 documentation (which is both
-copious and excellent). If you have any questions to
-which you can't find answers in these man pages, contact
-Luther Huffman at lutherh@stratcom.com and we'll try to
-answer them.
-
-=head2 Invoking Perl
-
-Perl is invoked from the command line as described in
-L<perl>. Most perl scripts, however, do have a first line
-such as "#!/usr/local/bin/perl". This is known as a shebang
-(shell-bang) statement and tells the OS shell where to find
-the perl interpreter. In Plan 9 Perl this statement should be
-"#!/bin/perl" if you wish to be able to directly invoke the
-script by its name.
- Alternatively, you may invoke perl with the command "Perl"
-instead of "perl". This will produce Acme-friendly error
-messages of the form "filename:18".
-
-Some scripts, usually identified with a *.PL extension, are
-self-configuring and are able to correctly create their own
-shebang path from config information located in Plan 9
-Perl. These you won't need to be worried about.
-
-=head2 What's in Plan 9 Perl
-
-Although Plan 9 Perl currently only provides static
-loading, it is built with a number of useful extensions.
-These include Opcode, FileHandle, Fcntl, and POSIX. Expect
-to see others (and DynaLoading!) in the future.
-
-=head2 What's not in Plan 9 Perl
-
-As mentioned previously, dynamic loading isn't currently
-available nor is MakeMaker. Both are high-priority items.
-
-=head2 Perl5 Functions not currently supported in Plan 9 Perl
-
-Some, such as C<chown> and C<umask> aren't provided
-because the concept does not exist within Plan 9. Others,
-such as some of the socket-related functions, simply
-haven't been written yet. Many in the latter category
-may be supported in the future.
-
-The functions not currently implemented include:
-
- chown, chroot, dbmclose, dbmopen, getsockopt,
- setsockopt, recvmsg, sendmsg, getnetbyname,
- getnetbyaddr, getnetent, getprotoent, getservent,
- sethostent, setnetent, setprotoent, setservent,
- endservent, endnetent, endprotoent, umask
-
-There may be several other functions that have undefined
-behavior so this list shouldn't be considered complete.
-
-=head2 Signals in Plan 9 Perl
-
-For compatibility with perl scripts written for the Unix
-environment, Plan 9 Perl uses the POSIX signal emulation
-provided in Plan 9's ANSI POSIX Environment (APE). Signal stacking
-isn't supported. The signals provided are:
-
- SIGHUP, SIGINT, SIGQUIT, SIGILL, SIGABRT,
- SIGFPE, SIGKILL, SIGSEGV, SIGPIPE, SIGPIPE, SIGALRM,
- SIGTERM, SIGUSR1, SIGUSR2, SIGCHLD, SIGCONT,
- SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU
-
-=head1 COMPILING AND INSTALLING PERL ON PLAN 9
-
-WELCOME to Plan 9 Perl, brave soul!
-
- This is a preliminary alpha version of Plan 9 Perl. Still to be
-implemented are MakeMaker and DynaLoader. Many perl commands are
-missing or currently behave in an inscrutable manner. These gaps will,
-with perseverance and a modicum of luck, be remedied in the near
-future.To install this software:
-
-1. Create the source directories and libraries for perl by running the
-plan9/setup.rc command (i.e., located in the plan9 subdirectory).
-Note: the setup routine assumes that you haven't dearchived these
-files into /sys/src/cmd/perl. After running setup.rc you may delete
-the copy of the source you originally detarred, as source code has now
-been installed in /sys/src/cmd/perl. If you plan on installing perl
-binaries for all architectures, run "setup.rc -a".
-
-2. After making sure that you have adequate privileges to build system
-software, from /sys/src/cmd/perl/5.00301 (adjust version
-appropriately) run:
-
- mk install
-
-If you wish to install perl versions for all architectures (68020,
-mips, sparc and 386) run:
-
- mk installall
-
-3. Wait. The build process will take a *long* time because perl
-bootstraps itself. A 75MHz Pentium, 16MB RAM machine takes roughly 30
-minutes to build the distribution from scratch.
-
-=head2 Installing Perl Documentation on Plan 9
-
-This perl distribution comes with a tremendous amount of
-documentation. To add these to the built-in manuals that come with
-Plan 9, from /sys/src/cmd/perl/5.00301 (adjust version appropriately)
-run:
-
- mk man
-
-To begin your reading, start with:
-
- man perl
-
-This is a good introduction and will direct you towards other man
-pages that may interest you.
-
-(Note: "mk man" may produce some extraneous noise. Fear not.)
