First, don't shoot the messenger ;-)
Second, what's one to do? Ant by contract does not support nested
properties, so what's Ant to do when it sees on opening ${? It looks for the
closing curly brace, which is found after ${a, which is thus interpreted as
the property name to reference?
I duplicated the Ant logic using JDK 1.4 regex, and have the same logic
using the "\\$\\{([^\\}]+)\\}" regex (in Java code, thus the escapes). I
even have a test case that shows what you just discovered:
protected void setUp() {
_ve = new VariableEvaluator();
_ve.putVariable("foo", "bar");
_ve.putVariable("ding", "dong");
_ve.putVariable("var${weird", "indeed");
}
public void test_evalString() {
assertEval(_ve, "${var${varname}}", "${var${varname}}", true);
assertEval(_ve, "${var${weird}}", "indeed}", false);
}
--DD
