/$when shipping.package /=> cart/items $map item => inv.get (item.sku,item.quantity})

Test numbers

$when:: expr.simplejson.do (x)
   ctx.json (x=x)

Calling with flatenning

   . (dieselScope[="res33"]=(a + b))

Complex objects

no inventory registered
class::DieselTestStudent (
    name,
    address:DieselTestAddress,
    name,
    address:DieselTestAddress)
no inventory registered
class::DieselTestAddress (
    street,
    no,
    street,
    no)

$when:: test.diesel.rule40
   . (student[="address"][="no"]="65")

Array ops

$when:: test.diesel.isin (x in ["123","234"], y not in [1,2])
   . (dieselScope[="y46"]=true)

simple scripting - JS by default

You can embed and use simple JS scripts like this:

fcall | jplay | splay
def: test.util.addMonths (mths)
  m = parseInt(mths);
  d = new Date();
  d.setMonth(d.getMonth() + m);
  x=0;
  // you can use for loops and any other JS construct that 
  // doesn't contain a double curly brace...
  for(i=0; i < 5; i++) {
    x = x+i;
  }
  return d.toISOString().replace(/T.*/g, '');
fcall | jplay | splay
def: test.util.today
  return new Date().toISOString().replace(/T.*/g, '');

Access to complex objects from/to JS:

Get values from input and send back as both payload and as a side effect:

fcall | jplay | splay
def: testdiesel.jstx (students)
  x = students[0].age;
  y = students[1].age;
  return x + y;
fcall | jplay | splay
def: testdiesel.jstxo (students)
  x = students[0].age;
  y = students[1].age;
  return {sum:x + y};
