Description
I've been playing a little with running Groovy scripts from within Java. Pretty simple how I am doing this:
Binding binding=new Binding();
int[] i=new int[1];
binding.setVariable("i", i);
GroovyShell shell=new GroovyShell(getClass().getClassLoader(), binding);
shell.evaluate("i[0]++");
Now the strange thing is that a compiler error occurs at i[0]++. I'd expected that it would take the first element of the array and increment it. Apparently I'm wrong. Here's the exception:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, General error during class
generation: BinaryExpression appeared on LHS. .
Node: org.codehaus.groovy.ast.expr.BinaryExpression. At [1:2] Script1.groovy
the script i[0]+=1 works.
There is another possibly related array operation problem.
def experienceScores = [ (INSPIRE):0, (RELAX):0, (ENERGIZE):0, (REVITALIZE):0 ] answers.values().each() { def cat = ANSWERS_BY_ID[it]?.category experienceScores[cat]++ }he postincrement doesn't work, and gives an error message that doesn't inspire confidence ("RuntimeParserException: Should not be called here"). Should this be working in 1.1 Beta 1? The problem is probably the map in use for experienceScores...
