I need to dynamically call a class method (i.e., unless there is some
other way, the name of the class method should be contained in a
variable). I have come up with the way illustrated in the example shown
below. The program is in the file, ‘test1’. The relevant method is in
the file, ‘Test1a.rb’. I use ‘eval’ which (I believe) is frowned upon.
Does anyone have a better way of accomplishing this objective? Thanks
for any input.

$ ls
test1 Test1a.rb
$ cat Test1a.rb
class Test1a
def Test1a.howdy()
return ‘Hello, world!’
end
end
$ cat test1
#!/usr/bin/ruby
I figured out that a comma-delimited list of any needed method arguments
may be appended to the variable containing the method name. I also
found ‘respond_to?’ which allows me to test whether a particular method
exists. Armed with this new knowledge, I think that I will be able to
get where I want to go.
Thanks for all the help.
