 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
 | This Lua module is used on approximately 54,000 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages. Consider discussing changes on the talk page before implementing them.
Transclusion count updated automatically (see documentation). |
 | This module depends on the following other modules: |
null
This module implements {{If preview}} and {{Preview warning}}. It helps templates/modules determine if they are being previewed.
Prefer implementing the template versions in other templates.
In a module to use the main(), you need to pass a frame table with an args table.
For the preview warning, use _warning().
local p = {}
local cfg = mw.loadData('Module:If preview/configuration')
--[[
main
This function returns either the first argument or second argument passed to
this module, depending on whether the page is being previewed.
]]
function p.main(frame)
if cfg.preview then
return frame.args[1] or ''
else
return frame.args[2] or ''
end
end
--[[
pmain
This function returns either the first argument or second argument passed to
this module's parent (i.e. template using this module), depending on whether it
is being previewed.
]]
function p.pmain(frame)
return p.main(frame:getParent())
end
local function warning_text(warning)
return mw.ustring.format(
cfg.warning_infrastructure,
cfg.templatestyles,
warning
)
end
function p._warning(args)
local warning = args[1] and args[1]:match('^%s*(.-)%s*$') or ''
if warning == '' then
return warning_text(cfg.missing_warning)
end
if not cfg.preview then return '' end
return warning_text(warning)
end
--[[
warning
This function returns a "preview warning", which is the first argument marked
up with HTML and some supporting text, depending on whether the page is being previewed.
