handler template The category handler template helps other templates to automate both categorization and For information about using the category handler template in other templates please see the template documentation Keep reading for information about using the category handler module in other Lua modules or for information on exporting this module to other wikis Use from other Lua modules When not to use this module For cases where a module only needs to categorise in one of the namespaces main articles file images or category then using this module is overkill Instead you can simply get a title object using mw title getCurrentTitle and check the nsText field For example local title mw title getCurrentTitle if title nsText File then do something end However if your module needs to categorize in any other namespace then we recommend you use this module since it provides proper category suppression and makes it easy to select how to categorize in the different namespaces Namespaces This module detects and groups all the different namespaces used on Wikipedia into several types These types are used as parameter names in this module main Main article space as in normal Wikipedia articles talk Any talk space such as page names that start with Talk User talk File talk and so on user wikipedia file The other namespaces except the talk pages Namespace aliases are also accepted See the table below for the full list other Any namespaces that were not specified as a parameter to the template See examples below List of possible namespace parameters excluding i talk i and i other i Namespace Aliasesmainphuich userwikiphiediy project wikipedia wpifl file phaph imagemiediywiki mediawikiaemaebb templatewithiich help hhmwdhmu categorysthaniyxyhnngsuxchbbrangtimedtextmxdul moduleBasic usage This module takes two or more parameters Here s an example using a hello world program p local categoryHandler require Module Category handler main function p main frame local result Hello world local category categoryHandler Category Somecat nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p The above example uses the default settings for the category handler module That means the example module will categorize on pages in the following namespaces main file help category portal and book But it will not categorize in any other namespaces e g talk user wikipedia mediawiki template And it will not categorize on blacklisted pages See section blacklist below The reason the category handler module does not categorize in some of the namespaces is that in those namespaces most modules and templates are just demonstrated or listed not used Thus most modules and templates should not categorize in those namespaces Any module or template that is meant for one or more of the namespaces where this module categorizes can use the basic syntax as shown above Advanced usage This module takes one or more parameters named after the different page types as listed in section namespaces above By using those parameters you can specify exactly in which namespaces your template should categorize Like this p local categoryHandler require Module Category handler main function p main frame local result This is a module meant for articles and talk pages local category categoryHandler main Category Somecat1 Categorize in main article space talk Category Somecat2 Categorize in talk space nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p The above module will only categorize in main and talk space But it will not categorize on archive pages since they are blacklisted See section blacklist below And if you need to demonstrate discuss the module on a talkpage then you can feed nocat true to prevent that template from categorizing See section nocat below Like this My new module Hey guys have you seen my new module invoke mymodule main nocat true Nice isn t it Sometimes we want to use the same category in several namespaces then do like this p local categoryHandler require Module Category handler main function p main frame local result This is a module used in several namespaces local category categoryHandler main Category Somecat1 1 Category Somecat2 For help and user space help 1 user 1 talk No categories on talk pages other Category Somecat3 For all other namespaces nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p In the above example we use a numbered parameter to feed one of the categories and then we tell this module to use that numbered parameter for both the help and user space The category handler module understands an unlimited number of numbered parameters The other parameter defines what should be used in the remaining namespaces that have not explicitly been fed data Note the empty but defined talk parameter That stops this module from showing what has been fed to the other parameter when in talk space The category handler module also has a parameter called all It works like this p local categoryHandler require Module Category handler main function p main frame local result This is a module used in all namespaces local category categoryHandler all Category Somecat1 Categorize in all namespaces nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p The above example will categorize in all namespaces but not on blacklisted pages If you want to demonstrate that module on a page then use nocat true to prevent the template from categorizing We suggest avoiding the all parameter since modules and templates should preferably only categorize in the namespaces they need to The all parameter can also be combined with the rest of the parameters Like this p local categoryHandler require Module Category handler main function p main frame local result This is a module used in all namespaces local category categoryHandler all Category Somecat1 Categorize in all namespaces main Category Somecat2 And add this in main space other Category Somecat3 And add this in all other namespaces nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p If the above module is placed on an article then it will add the categories Somecat1 and Somecat2 But on all other types of pages it will instead add Somecat1 and Somecat3 As the example shows the all parameter works independently of the rest of the parameters Subpages The category handler module understands the subpage parameter Like this p local categoryHandler require Module Category handler main function p main frame local result This is a module used in all namespaces local category categoryHandler subpage no Don t categorize on subpages wikipedia Category Somecat nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p If subpage no then this template will not categorize on subpages For the rare occasion you only want to categorize on subpages then use subpage only If subpage is empty or undefined then this template categorizes both on basepages and on subpages Blacklist This module has a blacklist of the pages and page types where templates should not auto categorize Thus modules that use this meta template will for instance not categorize on archive pages and on the subpages of If you want a template to categorize on a blacklisted page then feed nocat false to the module when you place it on the page thus skipping the blacklist check Note that this module only categorizes if it has data for the namespace For instance if the basic syntax is used see basic usage above then even if you set nocat false the template will not categorize on a talk page since it has no data for talk pages But it has data for help space so on a blacklisted help page it will categorize The blacklist is located in the configuration table cfg blacklist near the top of the module code The nocat parameter This module understands the nocat parameter If nocat true then this template does not categorize If nocat is nil then this template categorizes as usual If nocat false this template categorizes even when on blacklisted pages See section blacklist above The nocat parameter also accepts aliases for true and false as defined by Module Yesno e g yes y true and 1 for true and no n false and 0 for false Modules and templates that use category handler should forward nocat so they too understand nocat The code nocat frame args nocat shown in the examples on this page does that The categories parameter For backwards compatibility this module also understands the categories parameter It works the same as nocat Like this If categories false then this template does not categorize If categories is empty or undefined then this template categorizes as usual If categories true this template categorizes even when on blacklisted pages The categories parameter also accepts aliases for true and false as defined by Module Yesno e g yes y true and 1 for true and no n false and 0 for false The category2 parameter For backwards compatibility this template kind of supports the old category parameter But the parameter name category is already used in this module to feed category data for when in category space So instead this template uses category2 for the usage similar to nocat Like this If category2 empty but defined or category2 no or if category2 is fed any other data except as described in the next two points then this template does not categorize If category2 is undefined or if category2 then this template categorizes as usual If category2 yes this template categorizes even when on blacklisted pages Categories and text Besides from categories you can feed anything else to this module for instance some text Like this p local categoryHandler require Module Category handler main function p main frame local result This is a module used on talk pages local category categoryHandler talk Category Somecat other lt p class error gt This module should only be used on talk pages lt p gt nocat frame args nocat So nocat true false works category category or Check that we don t have a nil value for the category variable return result category end return p When the module code above is used on anything other than a talk page it will look like this This is a module used on talk pages This module should only be used on talk pages That text will not show on blacklisted pages so don t use this method to show any important information Feeding nocat true to the template hides the text just as it suppresses any categories The page parameter For testing and demonstration purposes this module can take a parameter named page Like this p local categoryHandler require Module Category handler main function p main frame local category categoryHandler main Category Some cat talk Category Talk cat nocat frame args nocat So nocat true false works page User talk Example return category end return p In the above code we on purpose left out the brackets around the category names so we see the output on the page No matter on what kind of page the code above is used it will return this Category Talk cat The page parameter makes this module behave exactly as if on that page Even the blacklist works The pagename doesn t have to be an existing page If the page parameter is empty or undefined the name of the current page determines the result You can make it so your module also understands the page parameter That means you can test how your template will categorize on different pages without having to actually edit those pages Then do like this p local categoryHandler require Module Category handler main function p main frame local category categoryHandler main Category Some cat talk Category Talk cat nocat frame args nocat So nocat true false works page frame args page For testing return category end return p Parameters List of all parameters First positional parameter for default settings subpage no only 1 2 3 all Category Somecat Text main 1 2 3 Category Somecat Text other 1 2 3 Category Somecat Text nocat frame args nocat true false yes no y n true false 1 0 categories frame args categories false true no yes n y false true 0 1 category2 frame args category or no not defined yes page frame args page User Example Note that empty values to the main other parameters have special meaning see examples above The all parameter doesn t understand numbered parameters since there should never be a need for that Exporting to other wikis This module can be exported to other wikis by changing the configuration values in the cfg table All the variable values are configurable so after the configuration values have been set there should be no need to alter the main module code Details of each configuration value are included in the module code comments In addition this module requires Module Namespace detect to be available on the local wiki See also Category handler for using this module with templates rather
