Attached. But this doesn't work with global variables and I haven't had chance to look at it.

Also the type of the string looks strange. I would expect that "std::wstring" is a typedef for "std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t>" You are using "std::__1::wstring" and the real type also contains this "__1" stuff "std::__1::basic_string<wchar_t, std::__1::char_traits<wchar_t>, std::__1::allocator<wchar_t>>" and it is additionally wrapped by a std::pair or sth similar. I've never seen this before. Maybe somebody else in the mailing list did?! So the wstring.py data formater works only for std::wstring with a "_M_dataplus" and a "_M_p" member Cheers, Nino Am 06.08.2012 19:47, schrieb Alexander Angriawan: I am using Mac OS X Version 10.7.4 The following is the lldb output: (lldb) frame variable x(std::__1::wstring) x = { __r_ = { std::__1::__libcpp_compressed_pair_imp<std::__1::basic_string<wchar_t, std::__1::char_traits<wchar_t>, std::__1::allocator<wchar_t> >::__rep, std::__1::allocator<wchar_t> > = { __first_ = { = { __l = { __cap_ = 17 __size_ = 12 __data_ = 0x00000001001009c0 } __s = { = { __size_ = '\x11' _ = \x11\0\0\0 } __data_ = { [0] = \0\0\0\0 [1] = \f\0\0\0 [2] = \0\0\0\0 [3] = \xc0\t\x10\0 [4] = \x01\0\0\0 } } __r = { __words = { [0] = 17 [1] = 12 [2] = 4296018368 } } } } } }}(lldb) Thanks, PA Date: Mon, 6 Aug 2012 11:24:48 +0200 From: [email protected] To: [email protected] Subject: Re: [lldb-dev] Formatter for std::shared_ptr<std::wstring> Hmm, thats strange. I'm currently using not the latest lldb, so maybe something changed. What platform are you developing on? The script is written for osx. Maybe you can just send me the output of "frame variable x" without having the script installed. Maybe the structure of your strings differ. N.
