Templating

FLAT's template language is intended to dynamically generate JSON documents.

Basically, you provide the skeleton of the JSON object you want to create, and use placeholders instead of literal values. The language supports template commands that are documented below. Template expressions and functions offer rich means of accessing request and response data in JSON, HTML or XML (OXN).

Comment {{// <comment>}}

Placeholder {{ <expression> }}

Dot {{.}}

Comma {{,}}

Pair Producer {{: <expression> }}

Variable Definition {{$<name> := <expression> }}

Conditional {{if <condition>}} … {{elseif <condition> }} … {{else}} … {{end}}

Loop {{loop <array>}} … {{end}}

Context Switch {{with <expression>}} … {{else}} … {{end}}

Null Coalescing Operator ??
