Method: Kernel#callstack

Defined in:
lib/garcon/core_ext/kernel.rb

#callstack(level = 1) ⇒ Object Also known as: call_stack

Parse a caller string and break it into its components, returning an array composed of:

  • file (String)

  • lineno (Integer)

  • method (Symbol)

For example, from irb

callstack(1)

produces …

[["(irb)", 2, :irb_binding],
  ["/usr/lib/ruby/1.8/irb/workspace.rb", 52, :irb_binding],
  ["/usr/lib/ruby/1.8/irb/workspace.rb", 52, nil]]

Note: If the user decides to redefine caller() to output data in a different format, prior to requiring this, then the results will be indeterminate.
