"Funkce analyzátoeu (parseru)" je konstrukt podobný šabloně, který vrací hodnotu na základě alespoň jednoho nepojmenovaného parametru odděleného od názvu funkce dvojtečkou [:]. Může existovat i více parametrů. Stejně jako u běžných šablon jsou tyto dodatečné parametry předcházeny "svislou čárkou" [|]. V případě znaku hash [#] na začátku názvu funkce (který zabraňuje kolizi s jmennými prostory a prefixy interwiki) může, ale nemusí být považován za součást názvu. Pokud je považován za součást názvu, syntaxe má tvar
- {{functionname: argument 1 | argument 2 | argument 3...}}
Arguments cannot directly contain "|" or "}}" except as part of the code of a template call, parser function call, variable, link or image, but they can contain them arbitrarily using a template, e.g., m:Template:!, or a parser function.
The code can specify whether the function name is case-sensitive.
The separation of the arguments from each other is with "|", and from the function name is with the first ":" The expansion of each of these pieces is standard, as in Special:ExpandTemplates (which is a good place to experiment, by the way, if you are learning this stuff) and is beyond the control of the parser function itself.
However, everything else can be different for each parser function, including:
- whether an argument is just a value, or of the form parname = parvalue, or whatever
- if applicable, whether parameter names are case-sensitive
Syntax prescribed by a parser function extension
In view of the above, it is advantageous to make an extension such that the syntax to be used in an argument does not contain the pipe character "|" or double braces (more specifically, double closing braces "}}" ). This, in spite of the fact that a pipe character would otherwise seem a suitable symbol for, e.g., a choice or union (see, e.g., ). Allowing such codes is harmless if an alternative code is also allowed, e.g. "\" for "|".
