-- Configuration
----------------------------------------------------------------------------

-- Here you can set the values of the parameters and messages used in this module, so that it
-- can be easily ported to other wikis.

-- Argument names
-- The following are all names of arguments that affect the behaviour of {{documentation}}.
-- The comments next to the configuration values are the effects that the argument has
-- on the module. (Not the effects of the argument names themselves.)

cfg.createModuleDocBlurb = 'You might want to $1 a documentation page for this [[Wikipedia:Lua|Scribunto module]].' -- Notice displayed in the module namespace when the documentation subpage does not exist. $1 is a link to create the documentation page with the preload cfg.modulePreload and the display cfg.createLinkDisplay.
cfg.templatePossessive = "template's" -- Possessive case for "template".
cfg.modulePossessive = "module's" -- Possessive case for "module".
cfg.experimentBlurb = 'Editors can experiment in this $1 $2 and $3 pages.' -- Text inviting editors to experiment in sandbox and test cases pages. It is only shown in the template and module namespaces. $1 is cfg.templatePossessive or cfg.modulePossessive depending on what namespace we are in. $2 is a link to the sandbox in the format "cfg.sandboxLinkDisplay (cfg.sandboxEditLinkDisplay | cfg.compareLinkDisplay)" if the sandbox exists, and the format "cfg.sandboxLinkDisplay (cfg.sandboxCreateLinkDisplay | cfg.mirrorLinkDisplay)" if the sandbox doesn't exist. If the sandbox link doesn't exist, the create link preloads the page with cfg.templateSandboxPreload or cfg.moduleSandboxPreload depending on the current namespace. $3 is a link to the test cases page in the format "cfg.testcasesLinkDisplay (cfg.testcasesEditLinkDisplay)" if the test cases page exists, and in the format "cfg.testcasesLinkDisplay (cfg.testcasesCreateLinkDisplay)" if the test cases page doesn't exist. If the test cases page doesn't exist, the create link preloads the page with cfg.templateTestcasesPreload or cfg.moduleTestcasesPreload depending on the current namespace.
