Wikipedia:Comparable Lua functions to wikitext

From Wikipedia, the free encyclopedia
This is an old revision of this page, as edited by 156.38.57.2 (talk) at 20:28, 1 July 2024 (MONTASAR). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This is a list of Lua functions and the wikitext parser functions and magic words that they are comparable to.

It is slightly out of date for what wikitext parser functions can do.

Parser functions

Wikitext Lua 
{{#if:x |not empty |empty}}

if x then
    'not empty'
else
    'empty'
end

{{#ifeq:x |y |identical |different}}

if x == y 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
[Expensive]
{{#ifexist:namespace:title |exists |doesn't exist}}
[Expensive] 
if mw.title.new('title', 'namespace').exists == true then
    "exists"
else
    "doesn't exist"
end

{{#rel2abs:path |basepath}}

{{#switch:{{{1}}} |foo=Foo |Bar}}

local cases = {
    default = "Bar",
    foo = "Foo",
}

local pframe = mw.getCurrentFrame():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)

{{#titleparts:pagename |number of segments to return |first segment to return}}
