Method: Kernel#call_stack

Defined in:
lib/core/facets/kernel/callstack.rb

#call_stack(level = 1) ⇒ Object

Parse a caller string and break it into its components, returning an array. Returns:

  • file (String)

  • lineno (Integer)

  • method (Symbol)

For example, from irb,

call_stack(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.
