+ * vm.c (RubyVM::FrameInfo): add a class to access each frame
+ information. You don't need to parse strings from caller().
+ FrameInfo has the following methods:
+ FrameInfo#name: method name, class name, etc with decorations.
+ FrameInfo#basename: name without decorations.
+ FrameInfo#line_no: line number.
+ FrameInfo#filename: file name.
+ FrameInfo#filepath: full filepath.
+ FrameInfo#iseq: iseq if it is iseq frame (defined by ruby script)
+ FrameInfo#to_s: return caller() method style string.
+ RubyVM::FrameInfoFrameInfo.caller(n, lev) returns array of
+ FrameInfo objects. The name "RubyVM::FrameInfoFrameInfo.caller"
+ is long and ambiguous (same as caller() method), we need to change
+ the name before Ruby 2.0 release.
+ Good names or comments are welcome.
+
+ * test/ruby/test_backtrace.rb: add a test for above change.
