Wikipedia:Porównanie funkcji Lua z wikitekstem

Poniższa lista zawiera porównianie funkcji Lua z odpowiadającymi im wikitekstowymi funkcjami parsera i magicznymi słowami.

Funkcje parsera

Wikitekst	Lua
{{#if: x | not empty | empty}}	if x then 'not empty' else 'empty' end
{{#ifeq: x | y | identical | different}}	if 1 == 3 then 'identical' else 'different' end
{{#iferror: function | bad | good }}	if tostring(mw.getCurrentFrame():preprocess('function')):find('<strong class="error"') then 'bad' else 'good' end
{{#ifexpr: 1+2=3 |true|false}}	if 1 + 2 == 3 then 'true' else 'false' end
[kosztowna] {{#ifexist: namespace:title | exists | doesn't exist }}	[kosztowna] if mw.title.new( 'title', 'namespace' ).exists == true then "exists" else "doesn't exist" end
rel2abs
{{#switch: {{{1}}} | foo = Foo | Bar }}	local cases = { default = "Bar", foo = "Foo", } local pframe = frame:getParent() local arg = pframe.args[1] cases[arg] or cases["default"]
{{#time: format | timestamp }}	mw.getContentLanguage():formatDate( 'format', 'timestamp' )
{{#timel: format | timestamp }}	mw.getContentLanguage():formatDate( 'format', 'timestamp', 1 )

Matematyczne

W przeciwieństwie do wikikodu, Lua nie wykorzystuje funkcji typu {{#ifexpr}}, czy {{#expr}}. Dodaj operatory i funkcje Lua bezprośrednio do twojego modułu.
