712 | =head2 build_substitutions_service |
713 | |
bbb306a9 |
714 | This method substitutes macros found with calls to a function. There are a |
715 | number of default macros: |
716 | |
717 | =over |
718 | |
719 | =item * C<__HOME__> - replaced with C<$c-E<gt>path_to('')> |
720 | |
721 | =item * C<__ENV(foo)__> - replaced with the value of C<$ENV{foo}> |
722 | |
723 | =item * C<__path_to(foo/bar)__> - replaced with C<$c-E<gt>path_to('foo/bar')> |
724 | |
725 | =item * C<__literal(__FOO__)__> - leaves __FOO__ alone (allows you to use |
726 | C<__DATA__> as a config value, for example) |
727 | |
728 | =back |
729 | |
730 | The parameter list is split on comma (C<,>). You can override this method to |
731 | do your own string munging, or you can define your own macros in |
732 | C<MyApp-E<gt>config-E<gt>{ 'Plugin::ConfigLoader' }-E<gt>{ substitutions }>. |
733 | Example: |
734 | |
735 | MyApp->config->{ 'Plugin::ConfigLoader' }->{ substitutions } = { |
736 | baz => sub { my $c = shift; qux( @_ ); } |
737 | } |
738 | |
739 | The above will respond to C<__baz(x,y)__> in config strings. |
a0146296 |
740 | |
d057ddb9 |
741 | =head2 build_extensions_service |
742 | |
bbb306a9 |
743 | Config::Any's available config file extensions (e.g. xml, json, pl, etc). |
744 | |
d057ddb9 |
745 | =head2 build_prefix_service |
746 | |
bbb306a9 |
747 | The prefix, based on the application name, that will be used to lookup the |
748 | config files (which will be in the format $prefix.$extension). If the app is |
749 | MyApp::Foo, the prefix will be myapp_foo. |
750 | |
d057ddb9 |
751 | =head2 build_path_service |
752 | |
bbb306a9 |
753 | The path to the config file (or environment variable, if defined). |
754 | |
d057ddb9 |
755 | =head2 build_config_service |
756 | |
bbb306a9 |
757 | The resulting configuration for the application, after it has successfully |
758 | been loaded, and all substitutions have been made. |
759 | |
d057ddb9 |
760 | =head2 build_raw_config_service |
761 | |
bbb306a9 |
762 | The merge of local_config and global_config hashes, before substitutions. |
763 | |
d057ddb9 |
764 | =head2 build_global_files_service |
765 | |
bbb306a9 |
766 | Gets all files for config that don't have the local_suffix, such as myapp.conf. |
767 | |
d057ddb9 |
768 | =head2 build_local_files_service |
769 | |
bbb306a9 |
770 | Gets all files for config that have the local_suffix, such as myapp_local.conf. |
771 | |
d057ddb9 |
772 | =head2 build_global_config_service |
773 | |
bbb306a9 |
774 | Reads config from global_files. |
775 | |
d057ddb9 |
776 | =head2 build_local_config_service |
777 | |
bbb306a9 |
778 | Reads config from local_files. |
779 | |
d057ddb9 |
780 | =head2 build_config_path_service |
781 | |
bbb306a9 |
782 | Splits the path to the config file, and returns on array ref containing |
783 | the path to the config file minus the extension in the first position, |
784 | and the extension in the second. |
785 | |
d057ddb9 |
786 | =head2 build_config_local_suffix_service |
787 | |
a0146296 |
788 | Determines the suffix of files used to override the main config. By default |
789 | this value is C<local>, which will load C<myapp_local.conf>. The suffix can |
790 | be specified in the following order of preference: |
791 | |
792 | =over |
793 | |
794 | =item * C<$ENV{ MYAPP_CONFIG_LOCAL_SUFFIX }> |
795 | |
796 | =item * C<$ENV{ CATALYST_CONFIG_LOCAL_SUFFIX }> |
797 | |
798 | =back |
799 | |
800 | The first one of these values found replaces the default of C<local> in the |
801 | name of the local config file to be loaded. |
802 | |
803 | For example, if C< $ENV{ MYAPP_CONFIG_LOCAL_SUFFIX }> is set to C<testing>, |
804 | ConfigLoader will try and load C<myapp_testing.conf> instead of |
805 | C<myapp_local.conf>. |
806 | |
bbb306a9 |
807 | =head2 build_locate_components_service |
808 | |
809 | This method is meant to provide a list of component modules that should be |
810 | setup for the application. By default, it will use L<Module::Pluggable>. |
811 | |
812 | Specify a C<setup_components> config option to pass additional options directly |
813 | to L<Module::Pluggable>. |
814 | |
815 | =head1 Other methods |
816 | |
a0146296 |
817 | =head2 get_component_from_sub_container($sub_container, $name, $c, @args) |
818 | |
819 | Looks for components in a given subcontainer (such as controller, model or view), and returns the searched component. If $name is undef, it returns the default component (such as default_view, if $sub_container is 'view'). If $name is a regexp, it returns an array of matching components. Otherwise, it looks for the component with name $name. |
8dc2fca3 |
820 | |
409db9cb |
821 | =head2 get_components_types |
822 | |
b4410fc3 |
823 | =head2 get_all_components |
824 | |
a0146296 |
825 | Fetches all the components, in each of the sub_containers model, view and controller, and returns a readonly hash. The keys are the class names, and the values are the blessed objects. This is what is returned by $c->components. |
826 | |
f147e6c2 |
827 | =head2 add_component |
828 | |
a0146296 |
829 | Adds a component to the appropriate subcontainer. The subcontainer is guessed by the component name given. |
830 | |
c4aedec7 |
831 | =head2 find_component |
832 | |
a0146296 |
833 | Searches for components in all containers. If $component is the full class name, the subcontainer is guessed, and it gets the searched component in there. Otherwise, it looks for a component with that name in all subcontainers. If $component is a regexp, it calls the method below, find_component_regexp, and matches all components against that regexp. |
834 | |
4e2b302e |
835 | =head2 find_component_regexp |
836 | |
a0146296 |
837 | Finds components that match a given regexp. Used internally, by find_component. |
838 | |
d3742403 |
839 | =head2 $c->expand_component_module( $component, $setup_component_config ) |
840 | |
841 | Components found by C<locate_components> will be passed to this method, which |
842 | is expected to return a list of component (package) names to be set up. |
