This template is used by Template:WPBannerMeta to provide the default class masks for WikiProject's quality scales. It also allows the easy implementation of customised class masks for WikiProject bannersm, and is suitable for projects which require a slightly different mask to the default one, and can be used in two different ways: with  and placed on the /class subpage of the WikiProject's banner template. In this case, specific guidance on how the template works with the chosen parameters is displayed on this page. with  and placed directly inside the class parameter. However this method is not suitable for projects which use either of the following: the B-class checklist; the taskforce hook.   Syntax  Typically this template should be placed on the/class subpage of a WikiProject banner template. {{class mask|{{{class|}}}  |topic=  |FQS=  |forceNA=  |b={{{b|B}}}  |category=  |disambig=  |portal=  |redirect=  |template=  |project=  |future=  |current=  |needed=  |merge= }}   Parameters   topic - set this parameter so that the documentation on the /class subpage links to the WikiProject's quality categories, e.g. if your quality categories are of the form :Category:B-Class mathematics articles, etc. then set .  class - this parameter must be passed as the first unnamed parameter in all cases.  FQS - if set to "yes", switches on the six additional classes Category, Disambig, Image, Portal, Template & Project. Individual classes may then be switched off by their respective parameters to "no".  forceNA - if set to "yes", will automatically classify pages tagged as  depending on the namespace of the page. The default setting is "no".  category, disambig, portal, redirect, template, project, future, current, needed, merge - if set to "yes", enables this quality class. The default for each is "no", unless FQS is set.  b - if the B-class checklist is used, this parameter must be passed through.   Example 1: subpage  The following code is placed in the banner template: |QUALITY_SCALE = subpage  |class = {{{class|}}} and on the/class subpage (for example Template:WikiProject Zimbabwe uses the subpage Template:WikiProject Zimbabwe/class), the following code is used: {{class mask | {{{class|}}}  |topic=Zimbabwe  |FQS=yes  |redirect=yes }} In this case all six of the "extended" quality classes are used, plus the additional Redirect-class. Because the  parameter is set, specific documentation will be displayed on the/class subpage.   Example 2: inline  The following code is placed in the banner template: |QUALITY_SCALE = inline  |class = {{class mask | {{{class|}}} | category=yes }} Now the standard quality classes are used, plus the additional Category-class. Reminder: this method is not suitable is the template uses the B-class checklist or the taskforce hook.   Subpages   Template:Class mask/core - the class mask itself  Template:Class mask/extended -  a version with the extended scale hard-wired, for use by Template:WPBannerMeta/class  Template:Class mask/sandbox - the template sandbox, used for experimentation  Template:Class mask/table - the documentation that is displayed on /class subpages  Template:Class mask/row - used by /table  Template:Class mask/doc - the documentation you are reading now   Uses   [ This] shows all /class subpages which use this template.
