=head1 NAME

Sub::Install - install subroutines into packages easily

=head1 VERSION

version 0.928

=head1 SYNOPSIS

  use Sub::Install;

  Sub::Install::install_sub({
    code => sub { ... },
    into => $package,
    as   => $subname
  });

=head1 DESCRIPTION

This module makes it easy to install subroutines into packages without the
unsightly mess of C<no strict> or typeglobs lying about where just anyone can
see them.

=head1 FUNCTIONS

=head2 install_sub

  Sub::Install::install_sub({
   code => \&subroutine,
   into => "Finance::Shady",
   as   => 'launder',
  });

This routine installs a given code reference into a package as a normal
subroutine.  The above is equivalent to:

  no strict 'refs';
  *{"Finance::Shady" . '::' . "launder"} = \&subroutine;

If C<into> is not given, the sub is installed into the calling package.

If C<code> is not a code reference, it is looked for as an existing sub in the
package named in the C<from> parameter.  If C<from> is not given, it will look
in the calling package.

If C<as> is not given, and if C<code> is a name, C<as> will default to C<code>.
If C<as> is not given, but if C<code> is a code ref, Sub::Install will try to
find the name of the given code ref and use that as C<as>.

That means that this code:

  Sub::Install::install_sub({
    code => 'twitch',
    from => 'Person::InPain',
    into => 'Person::Teenager',
    as   => 'dance',
  });

is the same as:

  package Person::Teenager;

  Sub::Install::install_sub({
    code => Person::InPain->can('twitch'),
    as   => 'dance',
  });

=head2 reinstall_sub

This routine behaves exactly like C<L</install_sub>>, but does not emit a
warning if warnings are on and the destination is already defined.

=head2 install_installers

This routine is provided to allow Sub::Install compatibility with
Sub::Installer.  It installs C<install_sub> and C<reinstall_sub> methods into
the package named by its argument.

 Sub::Install::install_installers('Code::Builder'); # just for us, please
 Code::Builder->install_sub({ name => $code_ref });

 Sub::Install::install_installers('UNIVERSAL'); # feeling lucky, punk?
 Anything::At::All->install_sub({ name => $code_ref });

The installed installers are similar, but not identical, to those provided by
Sub::Installer.  They accept a single hash as an argument.  The key/value pairs
are used as the C<as> and C<code> parameters to the C<install_sub> routine
detailed above.  The package name on which the method is called is used as the
C<into> parameter.

Unlike Sub::Installer's C<install_sub> will not eval strings into code, but
will look for named code in the calling package.

=head1 EXPORTS

Sub::Install exports C<install_sub> and C<reinstall_sub> only if they are
requested.

=head2 exporter

Sub::Install has a never-exported subroutine called C<exporter>, which is used
to implement its C<import> routine.  It takes a hashref of named arguments,
only one of which is currently recognize: C<exports>.  This must be an arrayref
of subroutines to offer for export.

This routine is mainly for Sub::Install's own consumption.  Instead, consider
L<Sub::Exporter>.

=head1 SEE ALSO

=over

=item L<Sub::Installer>

This module is (obviously) a reaction to Damian Conway's Sub::Installer, which
does the same thing, but does it by getting its greasy fingers all over
UNIVERSAL.  I was really happy about the idea of making the installation of
coderefs less ugly, but I couldn't bring myself to replace the ugliness of
typeglobs and loosened strictures with the ugliness of UNIVERSAL methods.

=item L<Sub::Exporter>

This is a complete Exporter.pm replacement, built atop Sub::Install.

=head1 EXTRA CREDITS

Several of the tests are adapted from tests that shipped with Damian Conway's
Sub-Installer distribution.
