Usage
editParserPower provides several parser functions, most notably {{#or:param1|param2|param3|...}}
, which returns the first nonempty value passed. This can be used as a syntax sugar for {{#if:{{{1|}}}|{{{1}}}|default}}
, and if {{{1|}}}
is instead a value requiring an expensive computation that won't get cached (e.g. the result of a Cargo query), it provides a Variables-free approach to do the computation only once.
Other parser functions include:
{{#follow:page title}}
, returning a page's name or its redirect target (expensive the first time it's used on a particular page){{#arraymap:value | delimiter | variable | formula | new_delimiter | conjunction}}
as in Page Forms (will not load if Page Forms is also installed){{#arraymaptemplate:value | template | delimiter | new_delimiter}}
as in Page Forms (will not load if Page Forms is also installed)- Several list-handling functions:
{{#lstcnt:list|separator}}
{{#lstsep:list|input separator|output separator}}
{{#lstelem:list|input separator|index}}
(1-indexed){{#lstsub:list|input separator|output separator|start index|length}}
{{#lstfnd:item to find|list|separator|case sensitivity option}}
{{#lstind:item to find|list|separator|options}}
{{#lstapp:list|separator|new item}}
{{#lstprep:new item|separator|list}}
{{#lstjoin:first list|first input separator|second list|second input separator|output separator}}
{{#listfilter:}}
{{#lstfltr:items to keep|items separator|list|input separator|output separator|case sensitivity option}}
{{#lstrm:item to remove|list|input separator|output separator|case sensitivity option}}
{{#lstcntuniq:list|separator|case sensitivity option}}
