$1 = Python Exception <class 'gdb.error'> There is no member or method named __first_.: about libcxx-pretty-printers HOT 5 CLOSED

The pretty printer for std::vector might be out of date regarding the structure of std::vector in memory. This might be due to a change in libcxx. The pretty printer code will have to be updated. I am not actively maintaining this project for the mean time, so I might need some time to perform the change.

Thank you for your readiness to help 👍 I really appreciate it!

The pretty printer code that might need adjustments starts here.

There is no documentation for the new structures, except in the source code of libcxx. The following implementations are the interesting parts to start with:

• The class __vector_base in vector,
• The class __compressed_pair in memory,
• The structure __compressed_pair_elem in memory.

Any hints on how to get this to work for queue? gdb complains I cannot perform division and modulo of two variables of type gdb.Value (inside the init method for StdDequePrinter. The exact error says: <class 'gdb.error'> Can't do that binary op on that type ). I tried to cast them to int but one of the values is optimized out and thus can't cast.

The std::queue pretty printing code might also be out of date with the changes to libc++. I opened the issue #4 for that, and I will try to work on it when I have some spare time. In the mean time, if you can fix it, then please do so and make a pull request.
