Get caller class

Question

I\'m writing Logger and got problem with automatic adding class name, from which I called print_log method. For example something like this:

class Logger
  def s

After futzing about with caller for a while, it's probably not going to do it for you, and neither is caller_locations. It's possible to track the classes of the last objects instantiated on the current thread, e.g.

class Class
  alias :_new :new
  def new *args
    Thread.current.thread_variable_set :classes, ((Thread.current.thread_variable_get(:classes) || []) << self).last(10)
    _new *args
  end
end

This retains the classes of the last 10 objects, but this isn't directly equivalent to a hierarchy e.g.

class X
  def initialize
    puts Thread.current.thread_variable_get(:classes)
  end
end

class Y
end

class Z
  def initialize
    @y = Y.new
    @x = X.new
  end
end

X.new outputs the following (in a console session)

RubyToken::TkNL
RubyToken::TkEND
RubyToken::TkNL
RubyToken::TkCONSTANT
RubyToken::TkDOT
RubyToken::TkIDENTIFIER
RubyToken::TkNL
Y
Z
X
