Getting name of current method

Ruby
#1

Ruby has FILE and LINE to give the file and line omber where we
are currently at in the code.

Consider
Class X
def my_method
m = ??? # I want m to be assigned “my_method”
end
end

How can I get m set properly?

I guess I could use define_method to define my_method and then pass the
name into the function … but that is so ugly and also flattens scope
that I may not want flattened.

Thanks for pointing that out. Interesting and useful.

I have come up with two alternate methods and I’d like to ask the help
of all those here to help me modify the first method so that it does
what I want

class X
@m = “method_1”
@s = <<-XXX
def #{@m}
puts “In #{@m}”
end
XXX

puts “#{FILE} @ #{LINE}”
puts @s
eval @s

m = “method_2”
eval(“def #{m}; puts “In #{m}”; end”)

end

x = X.new

x.method_1
x.method_2

The code, above, works fine in 1.8.6

Note that I have to define @m before @s. How can I set things up so
that I can define @m after @s so that I can modify @m and get a new
function?

What are you trying to achieve?

Kind regards
