The Syntax #
Parameter #
A parameter may be introduced through the use of {}, which mark a parameter
template. A parameter template can contain either a named parameter (through the
use of its name) or a positional one (through the use of its index).
Examples
Your name is {name} and your age is {age}.
The three chosen members are {0}, {1} and {2}.
Expression
An expression works a little like a switch statement. A parameter is passed into
an expression and checked against the defined cases. If the parameter matches a
case, its result is returned.
Expressions may be nested, and there is virtually no limit to how many cases an
expression can contain. However, for readability's sake, it is best to keep
expressions small and understandable.
[{parameter} ~ case1:result1/case2:result2/(...)]
[] introduce an expression
~ separates the parameter from the cases
: separates the result of a case from the case itself
/ separates cases and their results
Examples
[{age} ~ Lesser(18):You are underage!/Default:You are free to drink.]
[{temperature} ~ Lesser(15):Too cold./Lesser(30):Temperate./Default:It's too hot!]
Case Operations #
The parser supports several comparison operations, which can be used to match a
parameter to a case.
String-exclusive operations:

StartsWith
EndsWith
Contains

Indifferent operations:

Equals *
In
NotIn
InRange
NotInRange

Number-exclusive operations:

Greater
GreaterOrEqual
Lesser
LesserOrEqual

Other:

Default


If no operation has been defined, the operation will default to 'Equals'
