Groovy Power Print

Question

Groovy has a power assert, but I\'d like a power print. For example,

def foo = \'banna5\', monkey=7, x=70
println \"foo=$foo, monkey=$monkey, x/2=${x/2}\"

This may or may not work for you. it's Very Possible that it only works in scripts.

def pprint(def varClosure) {
    s=varClosure()
    print("\"$s\" = " + binding.variables[s])
}

test = 15

pprint{"test"}

I used a closure so it would pass the current context in (to get bindings). You can iterate over the closure in various ways--for instance if you pass pprint{["test","anotherVar"]} you could use this in stead of the println:

s.each() { print("\"$it\" = ${binding.variables[s]},\t") }
println ""

That would give pretty close to the results you wanted.

If you want to do it with a groovy class the bindings hash doesn't exist. There is a properties hash, but it only accesses object properties (not all variables available to the closure--in other words it would miss variables defined in the method and parameters).

Perhaps the closure has a hash of all properties available to it--that would be perfect. I'll look more later.

Also there is a dump() method on object that you might enjoy.
