The GString concept in Groovy is pretty powerful (see http://groovy.codehaus.org/Strings+and+GString). GStrings let you do things like: world = "World" println "Hello ${world}" # Output: Hello World println "1+2 = ${1+2}" # Output: 1+2 = 3 println "${System.exit(-1)}" # Program terminated I'm trying to figure out if using Groovy GStr...
Groovy has a concept of GStrings. I can write code like this: def greeting = 'Hello World' println """This is my first program ${greeting}""" I can access the value of a variable from within the String. How can I do this in Python? -- Thanks ...

I am hoping to use Groovy more as a functional language than I can with Java, but one area that seems to be a problem is when I call to a stored procedure, as I am passing perhaps 40 parameters in a single call, but, I also need to do some prep work, at the moment before I even call. So, for example, I need a time stamp, so I will have ...
I have the following code: public class TestGr { static String aaa = "wwww"; public static void main(args) { println "["+getAAA()+"]"; println "[" + getBBB() +"]"; } static String getAAA() { return "" + "${aaa}" } static String getBBB() { return "" + "${aaa}" } } The output of this code is:...
