First the name of the class needs to start with a capital letter, and since you really want to use a static method, the function name definition needs to start with self.
.
class TestClass
def self.test_function(someVar)
puts "I got the following variable: " + someVar
end
end
Then to invoke that from the command line you can do:
ruby -r "./test.rb" -e "TestClass.test_function 'hi'"
If you instead had test_function
as an instance method, you’d have:
class TestClass
def test_function(someVar)
puts "I got the following variable: " + someVar
end
end
then you’d invoke it with:
ruby -r "./test.rb" -e "TestClass.new.test_function 'hi'"
