nlohmann-json-gdb's Issues

.gdbinit instructions?

can you add the lines needed to automatically load this from .gdbinit? please assume zero python knowledge.

nlohmann_json.py needs "import gdb.printing"

I have downloaded nlohmann_json.py file, and in gdb, I have errors:

(gdb) source nlohmann_json.py 
PLATFORM_BITS 64
### Log info types output : All types matching regular expression "^nlohmann::basic_json<.*>$":
### Log info types output : 
### Log info types output : File ./headers/json.h:
### Log info types output : nlohmann::basic_json<std::map, std::vector, std::basic_string<char, std::char_traits<char>, std::allocator<char> >, bool, long, unsigned long, double, std::allocator, nlohmann::adl_serializer, std::vector<unsigned char, std::allocator<unsigned char> > >;

--------The researched nlohmann::basic_json type for this executable is---------
nlohmann::basic_json<std::map, std::vector, std::basic_string<char, std::char_traits<char>, std::allocator<char> >, bool, long, unsigned long, double, std::allocator, nlohmann::adl_serializer, std::vector<unsigned char, std::allocator<unsigned char> > >
(Using regex: ^nlohmann::basic_json<.*>$)

Traceback (most recent call last):
  File "nlohmann_json.py", line 375, in <module>
    gdb.printing.register_pretty_printer(
AttributeError: 'module' object has no attribute 'printing'

And then, I add this line in it

import gdb.printing

It is OK

(gdb) source nlohmann_json.py
