Files: MANIFEST lib/Class/Template.pm lib/File/stat.pm lib/Net/hostent.pm lib/Net/netent.pm lib/Net/protoent.pm lib/Net/servent.pm lib/Time/gmtime.pm lib/Time/localtime.pm lib/Time/tm.pm lib/User/grent.pm lib/User/pwent.pm

    These "should" be ready for inclusion in 5.004, although I'd like to
    update Class::Template's doc for legibility.  Dean, may we please have
    your permission to include this in the distribution?
    
    (I did look a bit into using Class::MethodMaker, but it seemed
    a bit complicated.)
    
    I know: these all look remarkably similar on the inside.  I keep trying
    to find a way to abstract out some of it.  Hopefully, they're reasonably
    legible at least in code, if not in docs. :-)
    
    Chip/Tim, please check the stat function for proper use of Symbol.
    
    thanks,

    # changes/bugs fixed since 20feb94 version:
    #  - Updated to be a more proper module.

    =head1 EXAMPLES
    X
    =item * Example 1
    X
    X	use Class::Template;
    X	
    X	struct( rusage => {
    X		ru_utime => timeval,
    X		ru_stime => timeval,
    X	});
    X	
    X	struct( timeval => [
    X		tv_secs  => '$',
    X		tv_usecs => '$',
    X	]);
    X
    X	my $s = new rusage;
    X
    =item * Example 2
    X
    X	package OBJ;
    X	use Class::Template;
    X
    X	members OBJ {
    X		'a'	=> '$',
    X		'b'	=> '$',
    X	};
    X
    X	members OBJ2 {
    X		'd'	=> '@',
    X		'c'	=> '$',
    X	};
    X
    X	package OBJ2; @ISA = (OBJ);
    X
    X	sub new {
    X		my $r = InitMembers( &OBJ::InitMembers() );
    X		bless $r;
    X	}
    X
    =head1 NOTES
    X 
    Use '%' if the member should point to an anonymous hash.  Use '@' if the
    member should point to an anonymous array.
    X
    When using % and @ the method requires one argument for the key or index
    into the hash or array.
    X
    Prefix the %, @, or $ with '*' to indicate you want to retrieve pointers to
    the values rather than the values themselves.

    =head1 NAME
    X
    File::stat.pm - by-name interface to Perl's built-in stat() functions
    X
    =head1 SYNOPSIS
    X
    X use File::stat;
    X $st = stat($file) or die "No $file: $!";
    X if ( ($st->mode & 0111) && $st->nlink > 1) ) {
    X     print "$file is executable with lotsa links\n";
    X } 
    X
    X use File::stat qw(:FIELDS);
    X stat($file) or die "No $file: $!";
    X if ( ($st_mode & 0111) && $st_nlink > 1) ) {
    X     print "$file is executable with lotsa links\n";
    X } 
    X
    =head1 DESCRIPTION
    X
    This module's default exports override the core stat() 
    and lstat() functions, replacing them with versions that return 
    "File::stat" objects.  This object has methods that
    return the similarly named structure field name from the
    stat(2) function; namely,
    dev,
    ino,
    mode,
    nlink,
    uid,
    gid,
    rdev,
    size,
    atime,
    mtime,
    ctime,
    blksize,
    and
    blocks.  
    X
    You may also import all the structure fields directly into your namespace
    as regular variables using the :FIELDS import tag.  (Note that this still
    overrides your stat() and lstat() functions.)  Access these fields as
    variables named with a preceding C<st_> in front their method names.
    Thus, C<$stat_obj-E<gt>dev()> corresponds to $st_dev if you import
    the fields.
    X
    To access this functionality without the core overrides,
    pass the C<use> an empty import list, and then access
    function functions with their full qualified names.
    On the other hand, the built-ins are still available
    via the C<CORE::> pseudo-package.
    X
    =head1 NOTE
    X
    While this class is currently implemented using the Class::Template
    module to build a struct-like class, you shouldn't rely upon this.

    Net::hostent - by-name interface to Perl's built-in gethost*() functions
    X
    =head1 SYNOPSIS
    X
    X use Net::hostnet;
    X
    =head1 DESCRIPTION
    X
    This module's default exports override the core gethostbyname() and
    gethostbyaddr() functions, replacing them with versions that return
    "Net::hostent" objects.  This object has methods that return the similarly
    named structure field name from the C's hostent structure from F<netdb.h>;
    namely name, aliases, addrtype, length, and addresses.  The aliases and
    addresses methods return array reference, the rest scalars.  The addr
    method is equivalent to the zeroth element in the addresses array
    reference.
    X
    You may also import all the structure fields directly into your namespace
    as regular variables using the :FIELDS import tag.  (Note that this still
    overrides your core functions.)  Access these fields as variables named
    with a preceding C<h_>.  Thus, C<$host_obj-E<gt>name()> corresponds to
    $h_name if you import the fields.  Array references are available as
    regular array variables, so for example C<@{ $host_obj-E<gt>aliases()
    }> would be simply @h_aliases.
    X
    The gethost() funtion is a simple front-end that forwards a numeric
    argument to gethostbyaddr() by way of Socket::inet_aton, and the rest
    to gethostbyname().
    X
    To access this functionality without the core overrides,
    pass the C<use> an empty import list, and then access
    function functions with their full qualified names.
    On the other hand, the built-ins are still available
    via the C<CORE::> pseudo-package.

    X	next;
    X    }
    X
    X    printf "\n%s is %s%s\n", 
    X	    $host,

    The getnet() functions do this in the Perl core:
    X
    X    sv_setiv(sv, (I32)nent->n_net);
    X
    The gethost() functions do this in the Perl core:
    X
    X    sv_setpvn(sv, hent->h_addr, len);
    X
    That means that the address comes back in binary for the
    host functions, and as a regular perl integer for the net ones.

    X use strict;

    X 
    X     print "\taliases are ", join(", ", @{$n->aliases}), "\n"
    X 		if @{$n->aliases};     
    X 
    X     # this is stupid; first, why is this not in binary?

    X     # to make it looks right

    X
    Net::servent - by-name interface to Perl's built-in getserv*() functions
    X
    =head1 SYNOPSIS
    X
    X use Net::servent;
    X $s = getservbyname(shift || 'ftp') || die "no service";
    X printf "port for %s is %s, aliases are %s\n",
    X    $s->name, $s->port, "@{$s->aliases}";
    X
    X use Net::servent qw(:FIELDS);
    X getservbyname(shift || 'ftp') || die "no service";
    X print "port for $s_name is $s_port, aliases are @s_aliases\n";
    X
    =head1 DESCRIPTION
    X
    This module's default exports override the core getservent(),
    getservbyname(), and
    getnetbyport() functions, replacing them with versions that return
    "Net::servent" objects.  They take default second arguments of "tcp".  This object has methods that return the similarly
    named structure field name from the C's servent structure from F<netdb.h>;
    namely name, aliases, port, and proto.  The aliases
    method returns an array reference, the rest scalars.
    X
    You may also import all the structure fields directly into your namespace
    as regular variables using the :FIELDS import tag.  (Note that this still
    overrides your core functions.)  Access these fields as variables named
    with a preceding C<n_>.  Thus, C<$serv_obj-E<gt>name()> corresponds to
    $s_name if you import the fields.  Array references are available as
    regular array variables, so for example C<@{ $serv_obj-E<gt>aliases()
    }> would be simply @s_aliases.
    X
    The getserv() function is a simple front-end that forwards a numeric
    argument to getservbyport(), and the rest to getservbyname().
    X
    To access this functionality without the core overrides,
    pass the C<use> an empty import list, and then access
    function functions with their full qualified names.
    On the other hand, the built-ins are still available
    via the C<CORE::> pseudo-package.
    X
    =head1 EXAMPLES
    X
    X use Net::servent qw(:FIELDS);
    X
    X while (@ARGV) {
    X     my ($service, $proto) = ((split m!/!, shift), 'tcp');
    X     my $valet = getserv($service, $proto);
    X     unless ($valet) {
    X         warn "$0: No service: $service/$proto\n"
    X         next;
    X     }
    X     printf "service $service/$proto is port %d\n", $valet->port;
    X     print "alias are @s_aliases\n" if @s_aliases;
    X }

    module to build a struct-like class, you shouldn't rely upon this.

    X
    This module's default exports override the core getgrent(), getgruid(),
    and getgrnam() functions, replacing them with versions that return
    "User::grent" objects.  This object has methods that return the similarly
    named structure field name from the C's passwd structure from F<grp.h>; 
    namely name, passwd, gid, and members (not mem).  The first three
    return scalars, the last an array reference.
    X
    You may also import all the structure fields directly into your namespace
    as regular variables using the :FIELDS import tag.  (Note that this still
    overrides your core functions.)  Access these fields as variables named
    with a preceding C<gr_>.  Thus, C<$group_obj-E<gt>gid()> corresponds
    to $gr_gid if you import the fields.  Array references are available as
    regular array variables, so C<@{ $group_obj-E<gt>members() }> would be
    simply @gr_members.
    X
    The getpw() funtion is a simple front-end that forwards
    a numeric argument to getpwuid() and the rest to getpwnam().
    X
    To access this functionality without the core overrides,
    pass the C<use> an empty import list, and then access

    User::pwent.pm - by-name interface to Perl's built-in getpw*() functions
    X
    =head1 SYNOPSIS
    X
    X use User::pwent;
    X $pw = getpwnam('daemon') or die "No daemon user";
    X if ( $pw->uid == 1 && $pw->dir =~ m#^/(bin|tmp)?$# ) {
    X     print "gid 1 on root dir";
    X } 
    X
    X use User::pwent qw(:FIELDS);
    X getpwnam('daemon') or die "No daemon user";
    X if ( $pw_uid == 1 && $pw_dir =~ m#^/(bin|tmp)?$# ) {
    X     print "gid 1 on root dir";
    X } 
    X
    X $pw = getpw($whoever);
    X
    =head1 DESCRIPTION
    X
    This module's default exports override the core getpwent(), getpwuid(),
    and getpwnam() functions, replacing them with versions that return
    "User::pwent" objects.  This object has methods that return the similarly
    named structure field name from the C's passwd structure from F<pwd.h>; 
    namely name, passwd, uid, gid, quota, comment, gecos, dir, and shell.
    X
    You may also import all the structure fields directly into your namespace
    as regular variables using the :FIELDS import tag.  (Note that this still
    overrides your core functions.)  Access these fields as
    variables named with a preceding C<pw_> in front their method names.
    Thus, C<$passwd_obj-E<gt>shell()> corresponds to $pw_shell if you import
    the fields.
    X
    The getpw() funtion is a simple front-end that forwards
    a numeric argument to getpwuid() and the rest to getpwnam().
    X
    To access this functionality without the core overrides,
    pass the C<use> an empty import list, and then access
    function functions with their full qualified names.
    On the other hand, the built-ins are still available
    via the C<CORE::> pseudo-package.
    X
    =head1 NOTE
    X
    While this class is currently implemented using the Class::Template
    module to build a struct-like class, you shouldn't rely upon this.

Subject: 10+ debugger patch
Date: Sun, 1 Dec 1996 06:37:31 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: lib/perl5db.pl perl.c pod/perldebug.pod

    Bugs corrected:
      perl.c
    	a) Could have deadlocked debugging its own signal handler;
      lib/perl5db.pl
      pod/perldebug.pod
    	b) Documentation (internal and POD) updated;
    	c) NonStop now will not stop at end;
    	d) variable names more meaningful now;
    	e) Will not trace last line of itself now;
    	f) Dumping of looong lines in a program (see Config.pm) interruptable;
    	g) $@ not wiped by evalled expressions;
    
    While updating the docs I was forced to change some API (to make it
    documentable), which resulted in following improvements:
    
    	frame & 4 recognized: more verbose output;
    	frame changes style of TRACE;
    	Non-interruptable lines have no `:' in the listing;
    	frame outputs `require'd packages as well.
    	added Options AutoTrace inhibit_exit
    
    Though this may look a lot, all the changes are not in the main flow
    of execution (in frills which are usually disabled), so I think they
    may be added even this late in the cycle. Documentation would be quite
    messy without these changes.
    
    As well as I know, the documentation is complete now, so one can
    _really_ write a new debugger from scratch.
    
    Enjoy,
