Wikifunctions:MediaWiki parser functions

This page is currently a draft. More information pertaining to this may be available on the talk page.

Translation admins: Normally, drafts should not be marked for translation.

Functions which have similar semantics to Wikitext parser functions (a.k.a. magic words) and templates used across wikis.

`{{GRAMMAR:elative\|wiki}}` (looks up the relevant declension for the given case)	19530 (declines any lexeme into the relevant form, as a string, based on the given feature)
`{{GENDER:Username\|male text\|female text\|text for unspecified}}` (chooses from given list of declensions based on some editor's gender setting)	19530 if it's encoded that way on Wikidata, else something like 19601 (chooses from Wikidata forms or given list of declensions based on variable)

Extension:ParserFunctions

MediaWiki	Function
`{{#expr:}}`	N/A; rewrite expression as a composition of logical and arithmetic functions, such as 13689 and 19708
`{{#if:}}`	10083
`{{#ifeq:}}`	compose 802 with 866
`{{#ifexpr:}}`	N/A per `{{#expr:}}`
`{{#switch:}}`	—
`{{#time:}}`	—

`{{#rpos:}}`	—
`{{#sub:}}`	—
`{{#count:}}`	14450
`{{#replace:}}`	—
`{{#explode:}}`	—
`{{#urldecode:}}`	10774 (imperfect match)

Module:String

These are the alternate string manipulation set used on WMF wikis, where $wgPFEnableStringFunctions is disabled. They mostly cover the same functionality as the ones from ParserExtensions but with different names and/or parameter semantics.

MediaWiki	Function
`{{#invoke:String\|len\|target_string}}`	11040
`{{#invoke:String\|sub\|target_string\|start_index\|end_index}}`	—
`{{#invoke:String\|match\|source_string\|pattern_string\|start_index\|match_number\|plain_flag\|nomatch_output}}`	—
`{{#invoke:String\|pos\|target_string\|index_value}}`	—
`{{#invoke:String\|find\|source_string\|target_string\|start_index\|plain_flag}}`	—
`{{#invoke:String\|replace\|source_str\|pattern_string\|replace_string\|replacement_count\|plain_flag}}`	—
