[Koha-patches] [PATCH 1/3] [1/3] Enhancement Bug 4444: Centralize Code Handling Perl Dependencies
Chris Nighswonger

Wed May 12 17:10:03 CEST 2010
This patch adds a file (installer/dependencies.yml) using yaml formatting to define the dependencies used by Koha and C4::Installer::PerlModule
which provides methods for accessing this data.
The format of dependencies.yml is very simple:
Foo::Bar:
min_ver: 0.01
required: 1
NOTE: yaml requires the use of spaces *not* tabs. Spacing is critical so follow the existing entries for sanity's sake.
New modules can be appended to dependencies.yml as needed and will be picked up by every piece of code which needs
this information.

+=head1 NAME
+
+C4::Installer::PerlModules
+
+=head1 ABSTRACT
+
+A module for manipulating Koha Perl dependency list objects.
+
+=head1 METHODS
+
+=head2 new()
+
+ Creates a new PerlModules object
+
+ example:
+ C<my $perl_modules = C4::Installer::PerlModules->new;>
+
+=head2 prereq_pm()
+
+ Returns a hashref of a hash of module information suitable for use in Makefile.PL
+
+ example:
+ C<my $perl_modules = C4::Installer::PerlModules->new;
+
+ ...
+
+ PREREQ_PM => $perl_modules->prereq_pm,>
+
+=head2 required()
+
+ This method accepts a single parameter with three possible values: a module name, the keyword 'required,' the keyword 'optional.' If passed the name of a module, a boolean value is returned indicating whether the module is required (1) or not (0). If on of the two keywords is passed in, it returns an arrayref to an array who's elements are the names of the modules specified either required or optional.
+
+ example:
+ C<my $is_required = $perl_modules->required(module => 'CGI::Carp');>
+
+ C<my $optional_pm_names = $perl_modules->required(optional => 1);>
+
+=head2 version_info()
+
+ Depending on the parameters passed when invoking, this method will give the current status of modules currently used in Koha as well as the currently installed version if the module is installed, the current minimum required version, and the upgrade status. If passed C<module => module_name>, the method evaluates only that module. If passed C<all => 1>, all modules are evaluated.
+
+ example:
+ C<my $module_status = $perl_modules->version_info(module => 'foo');>
+
+ This usage returns a hashref with a single key/value pair. The key is the module name. The value is an anonymous hash with the following keys:
+
+ cur_ver = version number of the currently installed version (This is 0 if the module is not currently installed.)
+ min_ver = minimum version required by Koha
+ upgrade = upgrade status of the module relative to Koha's requirements (0 if the installed module does not need upgrading; 1 if it does)
+ required = 0 of the module is optional; 1 if required
+
+ {
+ 'CGI::Carp' => {
+ 'required' => 1,
+ 'cur_ver' => '1.30_01',
+ 'upgrade' => 0,
+ 'min_ver' => '1.29'
+ }
+ };
+
+ C<$perl_modules->version_info;>
+
+ This usage loads the same basic data as the previous usage into three accessors: missing_pm, upgrade_pm, and current_pm. Each of these may be accessed by using the C<get_attr> method. Each accessor returns an anonymous array who's elements are anonymous hashes. They follow this format (NOTE: Upgrade status is indicated by the accessor name.):
+
+ [
+ {
+ 'Text::CSV::Encoded' => {
+ 'required' => 1,
+ 'cur_ver' => 0.09,
+ 'min_ver' => '0.09'
+ }
+ },
+ {
+ 'Biblio::EndnoteStyle' => {
+ 'required' => 1,
+ 'cur_ver' => 0,
+ 'min_ver' => '0.05'
+ }
+ },
+ }
+
+=head2 get_attr(attr_name)
+
+ Returns an anonymous array containing the contents of the passed in accessor. Valid accessors are:
+
+ missing_pm - Perl modules used by Koha but not currently installed.
+
+ upgrade_pm - Perl modules currently installed but below the minimum version required by Koha.
+
+ current_pm - Perl modules currently installed and up to date as required by Koha.
+
+ example:
+ C<my $missing_pm = $perl_modules->get_attr('missing_pm');>
+
+=head2 module_count
+
+ Returns a scalar value representing the current number of Perl modules used by Koha.
+
+ example:
+ C<my $module_count = $perl_modules->module_count;>
+
+=head2 module_list
+
+ Returns an array who's elements are the names of the Perl modules used by Koha.
+
+ example:
+ C<my @module_list = $perl_modules->module_list;>
+
+ This is useful for commandline exercises such as:
+
+ perl -MC4::Installer::PerlModules -e 'my $deps = C4::Installer::PerlModule->new; print (join("\n",$deps->module_list));'
