JsWizzi

JsWizzi is a subset of the ECMA-262 javascript standard used by the wizzi factory for processing ITTF Documents and build mTrees. JsWizzi uses the quite efficent babel parser and is run by a custom javascript engine ( JsWizziRunner ).

Ittf Documents may contain JsWizzi statements in

  • The value part of nodes (ITTF Node Values are interpolated)
    
                                        
       1 caption ${ name.capitalize() }
  • Conditional expression of $if, $elif, $while template commands
    
                                        
       1 $if name.substring(1,2) === 'is'
  • Collection name of $foreach template command
    
                                        
       1 $foreach item in model.getCollection('alfa')
  • Body of $ and $global template commands
    
                                        
       1 $ var beta = 100

Sample JsWizzi expressions and statements

                                
   1 ul
   2   $ var i = 0;
   3   $while i < 10
   4     li counting ${i}
   5     $ i++;
