This Lua module is used on approximately 468,000 pages, or roughly 53364% of all pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
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. disabled since we'll implement the template version in general ]] --function p.warning(frame) -- return p._warning(frame.args) --end --[[ warning, but for pass-through templates like {{preview warning}} ]] function p.pwarning(frame) return p._warning(frame:getParent().args) end return p
