Access variable value by its name as String (groovy)

Question

I've done some research but I haven't found a working code for my case. I have two variables named test and test2 and I want to put them in a map in the format [test:valueof(test), test2:valueof(test2)]

My piece of code is the following:

def test="HELLO"
def test2="WORLD"
def queryText = "\$\$test\$\$ \$\$test2\$\$ this is my test"

def list = queryText.findAll(/\$\$(.*?)\$\$/)

def map = [:]
list.each{
    it = it.replace("\$\$", "")
    map.putAt(it, it)
}

queryText = queryText.replaceAll(/\$\$(.*?)\$\$/) { k -> map[k[1]] ?: k[0] }

System.out.println(map)
System.out.println(queryText)

Output:

Desired output:

"HELLO WORLD this is my test"

I think I need something like map.putAt(it, eval(it))

EDIT

This is the way I get my inputs. the code goes into the 'test' script

The ones on the right are the variable names inside the script, the left column are the values (that will later be dynamic)

What is the data in RTFTemplates and Message1? Is your current groovy script in test? — Rao

Data in RTF Templates is irrelevant, the query attribute is a String with $$placeholders$$, message1 is just an empty box where I will return the result queryText processed by the script. Yes the script is in test — GiLA3

You are almost there.
The solution is instead of putting the values into separate variables put them into the script binding.

Add this at the beginning ( remove the variables test and test2):

def test="HELLO"
def test2="WORLD"
binding.setProperty('test', test)     
binding.setProperty('test2', test2)

and change this:

{ k -> map[k[1]] ?: k[0] }

to this:

{ k ->  evaluate(k[1]) }

Variables are already set prior to this piece of code, the def part was to make an example, my variables are retrieved as follows: #input String queryText,test,test2 since I'm using WebRatio. test already contains "HELLO" and test2 already contains "WORLD", same goes for queryText, so is there a way to adapt the binding.setProperty to my situation? Something like binding.setProperty('test',test) maybe?

{ k -> evaluate(k[1]) } was all I needed! binding is not needed in my case, even if I don't really understand why. Thanks a lot!

May be you should accept @dsharew 's answer instead.

It should be very simple if you could use TemplateEngine.

def text = '$test $test2 this is my test'
def binding = [test:'HELLO', test2:'WORLD']
def engine = new groovy.text.SimpleTemplateEngine() 
def template = engine.createTemplate(text).make(binding)
def result = 'HELLO WORLD this is my test'
assert result == template.toString()

You can test quickly online Demo

In my requirement I must use my variable names instead of 'HELLO' and 'WORLD' since those values change on every execution of the code. I need something like def binding = [test:valueof(test), test2:valueof(test2)]

Rao Over a year ago

What is the exact input that you receive? some where there should be mapping / binding of variable and its value, right?

Edited my question with the information you requested :)

Final working code, thanks to all, in particular to dsharew who helped me a lot!

#input String queryText,test,test2,test3

def list = queryText.findAll(/\$\$(.*?)\$\$/)

def map = [:]
list.each{
    it = it.replace("\$\$", "")
    map.putAt(it, it)
}

queryText = queryText.replaceAll(/\$\$(.*?)\$\$/) { k ->  evaluate(k[1]) }

return queryText
