-- NAMESPACE DETECT --
-- --
-- This module implements the {{namespace detect}} template in Lua, with a few --
-- improvements: all namespaces and all namespace aliases are supported, and namespace --
-- names are detected automatically for the local wiki. The module can also use the --
-- corresponding subject namespace value if it is used on a talk page. Parameter names --
-- can be configured for different wikis by altering the values in the "cfg" table. --
-- --
----------------------------------------------------------------------------------------------------

-- Configuration data --
-- Language-specific parameter names can be set here. --

-- This parameter displays content for the main namespace:
cfg.main = 'main'

-- This parameter displays in talk namespaces:
cfg.talk = 'talk'

-- This parameter displays content for "other" namespaces (namespaces for which
-- parameters have not been specified, or for when cfg.demospace is set to cfg.other):
cfg.other = 'other'

-- This parameter makes talk pages behave as though they are the corresponding subject namespace.
-- Note that this parameter is used with [[Module:Yesno]]. Edit that module to change
-- the default values of "yes", "no", etc.
cfg.subjectns = 'subjectns'
