NAME

Strict::Perl - Perl module to restrict old/unsafe constructs

SYNOPSIS

  use Strict::Perl 2018.03; # must version, must match

DESCRIPTION

Strict::Perl provides a restricted scripting environment excluding old/unsafe constructs, on both modern Perl and traditional Perl.

Strict::Perl works in concert with Modern::Open and Fake::Our if those are used in your script.

Version specify is required when use Strict::Perl, like;

  use Strict::Perl 2018.03;

It's die if specified version doesn't match Strict::Perl's version.

On Perl 5.010001 or later, Strict::Perl works as;

  use strict;
  use warnings qw(FATAL all); # not follow incompatible version-up of warnings.pm
  use Fatal # by compatible routine in Strict::Perl
  qw(
      seek sysseek
      dbmclose dbmopen
      binmode close chmod chown fcntl flock ioctl open sysopen truncate
      chdir closedir opendir link mkdir readlink rename rmdir symlink
      pipe
      msgctl msgget msgrcv msgsnd
      semctl semget semop
      shmctl shmget shmread
      accept bind connect getsockopt listen recv send setsockopt shutdown socketpair
      fork
  );
  use autodie qw(
      read sysread syswrite
      fileno
  );

On Perl 5.006 or later,

  use strict;
  use warnings qw(FATAL all); # not follow incompatible version-up of warnings.pm
  use Fatal # by compatible routine in Strict::Perl
  qw(
      seek sysseek
      dbmclose dbmopen
      binmode close chmod chown fcntl flock ioctl open sysopen truncate
      chdir closedir opendir link mkdir readlink rename rmdir symlink
      pipe
      msgctl msgget msgrcv msgsnd
      semctl semget semop
      shmctl shmget shmread
      accept bind connect getsockopt listen recv send setsockopt shutdown socketpair
      fork
  );

On Perl 5.00503 or later,

  use strict;
  $^W = 1;
  $SIG{__WARN__} = sub { die "$_[0]\n" }; # not follow incompatible version-up of warnings.pm
  use Fatal # by compatible routine in Strict::Perl
  qw(
      seek sysseek
      dbmclose dbmopen
      binmode close chmod chown fcntl flock ioctl open sysopen truncate
      chdir closedir opendir link mkdir readlink rename rmdir symlink
      pipe
      msgctl msgget msgrcv msgsnd
      semctl semget semop
      shmctl shmget shmread
      accept bind connect getsockopt listen recv send setsockopt shutdown socketpair
      fork
  );
