Basic Definition

A function has three things:

1. A name
2. Zero or more parameters
3. A list of strings to output

Syntax

WikiTalk uses the FlexWikiParameters feature to allow the creation of functions.

Note: It is apparently very important that there is no space between the ':' and the '{' after the parameter name.

 :TwoColumnRow:{ parameterOne, parameterTwo |
        [ "||{!}" , parameterOne , ":||", parameterTwo , "||" ]
 }
 @@TwoColumnRow("Header","Item1")@@
 @@TwoColumnRow("Header","Item2")@@
 @@TwoColumnRow("Header","Item3")@@

split into different @@ blocks

in the same @@ block

Here's a sample I agonized over for a while, scraped from _NormalBorders: (Wes Williamson - 2005/02/01)

I (BarryKelly) have struggled to get a looping construct to work. In the absence of variables, I've used recursive functions in a similar way to a functional language. For example:

 :CountUpTo:{
   n | 
     n.Equals(0)
       .IfTrue { "" }
       IfFalse { [ CountUpTo(n.Subtract(1)), Tab, "* ", n.ToString, Newline ] }
 }
 @@CountUpTo(10)@@

Gives:

• 1
• 2
• 3
• 4
• 5
• 6
• 7
• 8
• 9
• 10

You must be careful not to cause an infinte loop, or you'll need to restart aspnet_wp or w3wp on the web server.
