Can you pretend to be a computer?
Try interpreting the following trivial piece of nasal code "by hand".
Then see if the nasal interpreter agrees with your interpretation.
node = props.globals.getNode("/foo/bar", 1);
bar = getprop("/foo/bar");
if (bar == nil) {
str = "bar: nil, ";
} else {
str = "bar: non_nil, ";
}
if (bar) {
str ~= "pass, ";
} else {
str ~= "fail, ";
}
if (node.getBoolValue()) {
str ~= "true, ";
} else {
str ~= "false, ";
}
print(str, node.getBoolValue(), ":", node.getValue());
