__DIR__()

Return the directory of the file.

  end

__FILE__()

Returns file name.

[ show source ]

    eval("__FILE__")
  end

__FILE__()

Returns file name.

  def __FILE__
    eval("__FILE__")
  end

__LINE__()

Returns line number.

__callee__()

Retreive the current running method.

  def tester; p called; end
  tester  #=> :tester

[ show source ]

# File lib/core/facets/binding/caller.rb, line 36
  def __callee__
    name = /\`([^\']+)\'/.match(caller(1).first)[1]
    return name.to_sym
  end

__callee__()

Retreive the current running method.

  def tester; p called; end
  tester  #=> :tester

    name = /\`([^\']+)\'/.match(caller(1).first)[1]
    return name.to_sym
  end

__method__()

There is a lot of debate on what to call this. method_name differs from called only by the fact that it returns a string, rather then a symbol.

  def tester; p methodname; end
  tester  #=> "tester"

[ show source ]

# File lib/core/facets/binding/caller.rb, line 48
  def __method__
    name = /\`([^\']+)\'/.match(caller(1).first)[1]
