I gave my debugger a std

Tired of doing a 'p/x *this' only to be confounded by a bunch of gibberish about std:: etc? Maybe you want to add this to your ~/.gdbinit:

cat ~/.gdbinit 
python
import sys
sys.path.insert(0, '/usr/share/gcc-8/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

Now when you print a string or a list or deque, it works. What sourcery is this? Well, you may have this installed:

$ dpkg -S /usr/share/gcc-8/python/libstdcxx/v6/printers.py 
libstdc++6:amd64: /usr/share/gcc-8/python/libstdcxx/v6/printers.py

Its a pretty printer. Disabled and sad. You can tell by running the command 'info pretty-printer'. If its enabled, you'll see something like this:

global pretty-printers:
builtin
mpx_bound128
libstdc++-v6
__gnu_cxx::_Slist_iterator 
__gnu_cxx::__8::_Slist_iterator
__gnu_cxx::__8::__normal_iterator
__gnu_cxx::__8::slist
__gnu_cxx::__normal_iterator
__gnu_cxx::slist
__gnu_debug::_Safe_iterator
std::_Deque_const_iterator 
std::_Deque_iterator 
std::_Fwd_list_const_iterator
std::_Fwd_list_iterator
std::_List_const_iterator

Looks like fun.
