<div class="ecxmoz-cite-prefix">Hi Alexander,<br>
<br>
your string implementation looks very complicated.<br>
<br>
Also the type of the string looks strange. I would expect that
"std::wstring" is a typedef<br>
for "std::basic_string<wchar_t,
std::char_traits<wchar_t>, std::allocator<wchar_t>"<br>
<br>
You are using "std::__1::wstring" and the real type also contains
this "__1" stuff<br>
"std::__1::basic_string<wchar_t,
std::__1::char_traits<wchar_t>,
std::__1::allocator<wchar_t>>"<br>
and it is additionally wrapped by a std::pair or sth similar. <br>
<br>
I've never seen this before. Maybe somebody else in the mailing
list did?!<br>
<br>
So the wstring.py data formater works only for std::wstring with a
"_M_dataplus" and a "_M_p" member<br>
<br>
Cheers,<br>
Nino<br>

I'm currently using not the latest lldb, so maybe
something changed.<br>
<br>
What platform are you developing on? The script is written
for osx.<br>
<br>
Maybe you can just send me the output of "frame variable
x" without having the script installed. Maybe the
structure of your strings differ.<br>

I've seen, that the script attached to the mail

Yust copy the script to your hom directory and
ad the folowing line to your .lldbinit<br>
<br>
script sys.path[:0] = [os.path.expanduser('~')]<br>
command alias pwd script print os.getcwd()<br>
