| 21 | =head1 SYNOPSIS | ||||
| 22 | |||||
| 23 | use Sub::Install; | ||||
| 24 | |||||
| 25 | Sub::Install::install_sub({ | ||||
| 26 | code => sub { ... }, | ||||
| 27 | into => $package, | ||||
| 28 | as => $subname | ||||
| 29 | }); | ||||
| 30 | |||||
| 31 | =head1 DESCRIPTION | ||||
| 32 | |||||
| 33 | This module makes it easy to install subroutines into packages without the | ||||
| 34 | unslightly mess of C<no strict> or typeglobs lying about where just anyone can | ||||
| 35 | see them. | ||||
| 36 | |||||
| 37 | =head1 FUNCTIONS | ||||
| 38 | |||||
| 39 | =head2 install_sub | ||||
| 40 | |||||
| 41 | Sub::Install::install_sub({ | ||||
| 42 | code => \&subroutine, | ||||
| 43 | into => "Finance::Shady", | ||||
| 44 | as => 'launder', | ||||
| 45 | }); | ||||
| 46 | |||||
| 47 | This routine installs a given code reference into a package as a normal | ||||
| 48 | subroutine. The above is equivalent to: | ||||
| 49 | |||||
| 50 | no strict 'refs'; | ||||
| 51 | *{"Finance::Shady" . '::' . "launder"} = \&subroutine; | ||||
| 52 | |||||
| 53 | If C<into> is not given, the sub is installed into the calling package. | ||||
| 54 | |||||
| 55 | If C<code> is not a code reference, it is looked for as an existing sub in the | ||||
| 56 | package named in the C<from> parameter. If C<from> is not given, it will look | ||||
| 57 | in the calling package. | ||||
| 58 | |||||
| 59 | If C<as> is not given, and if C<code> is a name, C<as> will default to C<code>. | ||||
| 60 | If C<as> is not given, but if C<code> is a code ref, Sub::Install will try to | ||||
| 61 | find the name of the given code ref and use that as C<as>. | ||||
| 62 | |||||
| 63 | That means that this code: | ||||
| 64 | |||||
| 65 | Sub::Install::install_sub({ | ||||
| 66 | code => 'twitch', | ||||
| 67 | from => 'Person::InPain', | ||||
| 68 | into => 'Person::Teenager', | ||||
| 69 | as => 'dance', | ||||
| 70 | }); | ||||
| 71 | |||||
| 72 | is the same as: | ||||
| 73 | |||||
| 74 | package Person::Teenager; | ||||
| 75 | |||||
| 76 | Sub::Install::install_sub({ | ||||
| 77 | code => Person::InPain->can('twitch'), | ||||
| 78 | as => 'dance', | ||||
| 79 | }); | ||||
| 80 | |||||
| 81 | =head2 reinstall_sub | ||||
| 82 | |||||
| 83 | This routine behaves exactly like C<L</install_sub>>, but does not emit a | ||||
| 84 | warning if warnings are on and the destination is already defined. | ||||

| 295 | This module is (obviously) a reaction to Damian Conway's Sub::Installer, which | ||||
| 296 | does the same thing, but does it by getting its greasy fingers all over | ||||
| 297 | UNIVERSAL. I was really happy about the idea of making the installation of | ||||
| 298 | coderefs less ugly, but I couldn't bring myself to replace the ugliness of | ||||
| 299 | typeglobs and loosened strictures with the ugliness of UNIVERSAL methods. | ||||

| 301 | =item L<Sub::Exporter> | ||||
| 302 | |||||
| 303 | This is a complete Exporter.pm replacement, built atop Sub::Install. | ||||
