NAME

Mail::Toaster::Perl - Perl specific functions for Mail Toaster

SYNOPSIS

Perl functions for loading, installing and testing perl modules.

DESCRIPTION

Mail::Toaster::Perl is a few frequently used functions that make dealing with perl and perl modules a little more managable. The following methods are available:

check       - checks perl version
install     - installs perl
module_load - loads a perl module (attempts to install if missing)

See the description for each method below.

METHODS

new

To use a a method in this class, you must first request a Mail::Toaster::Perl object:

use Mail::Toaster::Perl;
my $perl = Mail::Toaster::Perl->new();

You can then call subsequent methods with $perl->method();

check

Checks perl to make sure the version is higher than a minimum (supplied) value.

  $perl->check( min=>'5.006001' );

arguments required:
   min - defaults to 5.6.1 (5.006001).

arguments optional:
   timer - default 60 seconds
   debug
   
usage:
  $perl->check( min=>5.006001 );

returns 1 for success, 0 for failure.

has_module

Checks to see if a perl module is installed.

  if ( $perl->has_module("Date::Format") ) {
      print "yay!\n";
  };

arguments required:
   module - the name of the perl module

arguments optional:
   version - minimum version
module_install

Downloads and installs a perl module from sources.

The arguments get concatenated to a url like this: $site/$url/$module.tar.gz

Once downloaded, we expand the archive and attempt to build it. If not set, the default targets are: make, make test, and make install. After install, we clean up the sources and exit.

This method builds from sources only. Compare to module_load which will attempt to build from FreeBSD ports, CPAN, and then finally resort to sources if all else fails.

usage:
   $perl->module_install( module=>"Params::Validate", conf=>$conf );

Example:

   $perl->module_install(
      module   => 'Mail-Toaster',
      archive  => 'Mail-Toaster-4.01.tar.gz',
      site     => 'http://www.tnpi.net',
      url      => '/internet/mail/toaster/src',
      targets  => ['perl Makefile.PL', 'make install'],
   );

arguments required:
   module  - module name          (CGI)
   site    - site to download from
   url     - path to downloads on site
   

arguments optional:
   archive - archived module name (CGI-1.35.tar.gz)
   targets - build targets: 
   conf    - $conf is toaster-watcher.conf settings, (barely) optional.

result:
   1 - success
   0 - failure.
module_load
$perl->module_load( module=>'Net::DNS' );

Loads a required Perl module. If the load fails, we attempt to install the required module (rather than failing gracelessly).

arguments required:
   module      - the name of the module: (ie. LWP::UserAgent)
   
arguments optional:
   port_name  - is the name of the FreeBSD port
   port_group - is is the ports group ( "ls /usr/ports" to see groups)
   warn        - if set, we warn instead of dying upon failure
   timer       - how long (in seconds) to wait for user input (default 60)
   site        - site to download sources from
   url         - url at site (see module_install)
   archive     - downloadable archive name (module-1.03.tar.gz)

returns 1 for success, 0 for failure.

perl_install
$perl->perl_install( version=>"perl-5.8.5" );

currently only works on FreeBSD and Darwin (Mac OS X)

input is a hashref with the following values:

version - perl version to install
options - compile flags to set (comma separated list)

On FreeBSD, version is the directory name such as "perl5.8" derived from /usr/ports/lang/perl5.8. Ex: $perl->perl_install( version=>"perl5.8" );

On Darwin, it's the directory name of the port in Darwin Ports. Ex: $perl->perl_install( {version=>"perl-5.8"} ) because perl is installed from /usr/ports/dports/lang/perl5.8. Otherwise, it's the exact version to download and install, ex: "perl-5.8.5".

Example with option:

$perl->perl_install( version=>"perl-5.8.5", options=>"ENABLE_SUIDPERL" );
