Calling a method whose name I only know at run-time

Hi folks,

I have a handful of methods that perform operations on chunks of data.
Which of these methods is called is specified in a YAML configuration so
I only know the method names at run-time, which are, of course, strings.
I am familiar with eval but would like to avoid using it to keep my code
safe. Is there another way I can do it?

Thanks,

Chad.

Oops, solved it. Sorry, I missed Object#method the first time around.

And there is the Object#send that will do what you want, i.e.
any_object.send("method1", arg1, arg2)

or

any_object.send("method1", *args)

(if send insists on symbols for method names, use String#to_sym)

It looks like send is actually more appropriate for my needs, thanks,
I'll give it a go.
