You can use Function. Caller to get the calling function.
A trace of the method calls is called a stack trace. The stack trace listing provides a way to follow the call stack to the line number in the method where the exception occurs. The StackTrace property returns the frames of the call stack that originate at the location where the exception was thrown.
puts caller[0]
or perhaps...
puts caller[0][/`.*'/][1..-2]
In Ruby 2.0.0, you can use:
caller_locations(1,1)[0].label
It's much faster than the Ruby 1.8+ solution:
caller[0][/`([^']*)'/, 1]
Will get included in backports
when I get the time (or a pull request!).
Use caller_locations(1,1)[0].label
(for ruby >= 2.0)
Edit: My answer was saying to use __method__
but I was wrong, it returns the current method name.
I use
caller[0][/`([^']*)'/, 1]
How about
caller[0].split("`").pop.gsub("'", "")
Much cleaner imo.
Instead you can write it as library function and make a call wherever needed. The code goes as follows :
module CallChain
def self.caller_method(depth=1)
parse_caller(caller(depth+1).first).last
end
private
# Copied from ActionMailer
def self.parse_caller(at)
if /^(.+?):(\d+)(?::in `(.*)')?/ =~ at
file = Regexp.last_match[1]
line = Regexp.last_match[2].to_i
method = Regexp.last_match[3]
[file, line, method]
end
end
end
To trigger the above module method you need to call like this:
caller = CallChain.caller_method
