Apache::Logmonster::Perl - perl specific utility subs, check_perl, has_module, install_module, etc

Perl functions for working with perl and loading modules.

Apache::Logmonster::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.

new

To use a a method in this class, you must first request a Apache::Logmonster::Perl object:

  use Apache::Logmonster::Perl;
  my $perl = Apache::Logmonster::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.biz',
       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" );
