hi,
I have a test method that writes some xml. The second parameter is
optional, the first parameter is boolean.
test_results((assert(REMEMBER_ME.isSet?)), *msg)
Would it be possible to embed a conditional statement between these
parameters
Something like:
test_results((assert(REMEMBER_ME.isSet?)), unless 'the object is not
set') ?

Yes, but it’s not necessarily pretty:
def test(one, *two)
puts one
two.each { |t| puts t}
end
irb> test(“bob”, “jack”, “andy”)
bob
jack
andy
irb> test(“bob”)
bob
irb> some_condition = false
irb> test(“bob”, some_condition ? [“jack”, “andy”] : [])
bob
irb>
The “optional” argument is actually a list, so passing in the empty list
for it is the same thing as not passing it in.
Cheers,
Reuben

I’m not sure what you are trying to achieve. But it seems strange to
have an assert and caveat with an “unless”. Can you explain a bit more
what you want to do?
Kind regards

I think you missed a ‘*’ on the method call there.
As you’ve written it, in each case you’re passing exactly two arguments,
the
second of which is either [“jack”,“andy”] or [], so the array ‘two’ will
consist of either [[“jack”,“andy”]] or [[]]
def test(one, *two)
puts one.inspect, two.inspect
puts
end
test(“bob”,“jack”,“andy”)
test(“bob”)
[false,true].each do |some_condition|
test(“bob”, some_condition ? [“jack”, “andy”] : [])
end
This is what it should have been
[false,true].each do |some_condition|
test(“bob”, *(some_condition ? [“jack”, “andy”] : []))
end
