NAME¶
Apache2::Module - Perl API for creating and working with Apache modules
Synopsis¶

Description¶
"Apache2::Module" provides the Perl API for creating and working with Apache modules
See Apache Server Configuration Customization in Perl.
API¶
"Apache2::Module" provides the following functions and/or methods:
"add"¶
Add a module's custom configuration directive to Apache.
Apache2::Module::add($package, $cmds);
- arg1: $package ( string )
- the package of the module to add
- arg2: $cmds ( ARRAY of HASH refs )
- the list of configuration directives to add
- ret: no return value
- since: 2.0.00
See also Apache Server Configuration Customization in Perl.
"ap_api_major_version"¶
Get the httpd API version this module was build against, not the module's version.
$major_version = $module->ap_api_major_version();
This methid is used to check that module is compatible with this version of the server before loading it.
"ap_api_minor_version"¶
Get the module API minor version.
$minor_version = $module->ap_api_minor_version();
ap_api_minor_version() provides API feature milestones.
It's not checked during module init.
"cmds"¶
Get the "Apache2::Command" object, describing all of the directives this module defines.
$command = $module->cmds();
"get_config"¶
Retrieve a module's configuration. Used by configuration directives.
$cfg = Apache2::Module::get_config($class, $server, $dir_config); $cfg = Apache2::Module::get_config($class, $server); $cfg = $self->get_config($server, $dir_config); $cfg = $self->get_config($server);
- obj: $module ( "Apache2::Module object" )
- arg1: $class ( string )
- The Perl package this configuration is for
- arg2: $server ( "Apache2::ServerRec object" )
- The current server, typically "$r->server" or "$parms->server".
- opt arg3: $dir_config ( "Apache2::ConfVector object" )
- By default, the configuration returned is the server level one. To retrieve the per directory configuration, use "$r->per_dir_config" as a last argument.
- ret: $cfg (HASH reference)
- A reference to the hash holding the module configuration data.
- since: 2.0.00
See also Apache Server Configuration Customization in Perl.
"find_linked_module"¶
Find a module based on the name of the module
$module = Apache2::Module::find_linked_module($name);
- arg1: $name ( string )
- The name of the module ending in ".c"
- ret: $module ( "Apache2::Module object" )
- The module object if found, "undef" otherwise.
- since: 2.0.00
For example:
my $module = Apache2::Module::find_linked_module('mod_ssl.c');
"loaded"¶
Determine if a certain module is loaded
$loaded = Apache2::Module::loaded($module);
- name: $module ( string )
- The name of the module to search for.
If $module ends with ".c", search all the modules, statically compiled and dynamically loaded.
If $module ends with ".so", search only the dynamically loaded modules.
If $module doesn't contain a ".", search the loaded Perl modules (checks %INC).
- ret: $loaded ( boolean )
- Returns true if the module is loaded, false otherwise.
- since: 2.0.00
For example, to test if this server supports ssl:
if (Apache2::Module::loaded('mod_ssl.c')) { [...] }
To test is this server dynamically loaded mod_perl:
if (Apache2::Module::loaded('mod_perl.so')) { [...] }
To test if "Apache2::Status" is loaded:
if (Apache2::Module::loaded('Apache2::Status')) { [...] }
"module_index"¶
Get the index to this modules structures in config vectors.
$index = $module->module_index();
"name"¶
Get the name of the module's .c file
$name = $module->name();
For example a mod_perl module, will return: mod_perl.c.
"next"¶
Get the next module in the list, "undef" if this is the last module in the list.
$next_module = $module->next();
"remove_loaded_module"¶
Remove a module from the list of loaded modules permanently.
$module->remove_loaded_module();
"top_module"¶
Returns the first module in the module list. Useful to start a module iteration.
$module = Apache2::Module::top_module();
