Generate Variables from JSON
When working with string properties, the varsFromStrProp() function is an automated way to generate variables from the keys within a string property. For example, if you have the following string property:
[prop = "name=Axe; damage=1d12; proficiency=2;"]
You can use varsFromStrProp() to generate a variable for each key - in other words, using the function to generate a list of locally accessible variables name
, damage
, and proficiency
.
There is no equivalent function for JSON objects. However, the following routine can be inserted into any macro to efficiently generate the variables in question.
[h:varList=json.fields(testObj)]
[h,foreach(var,varList),CODE:
{
[value = json.get(testObj,var)]
[set(var,value)]
}]
The variable testObj
represents the JSON object that is fed into the routine. The variables generated will be available within the scope of the running macro (but not outside).
