Visual Debugging Now
- eesmith 4y ago> But the debugger is programmable itself, and uses Python natively as a scripting language. like lldb? https://lldb.llvm.org/use/python.html https://lldb.llvm.org/use/python.html """LLDB has been structured from the beginning to be scriptable in two ways – a Unix Python session can initiate/run a debug session non-interactively using LLDB; and within the LLDB debugger tool, Python scripts can be used to help with many tasks, including inspecting program data, iterating over containers and determining if a breakpoint should stop execution or continue.""" > Extend your favorite C++ compiler with a flag that generates python bindings for all data variable symbols. The linked-to lldb documentation has a section on "Accessing & Manipulating Program Variables". I'm pretty sure it can all be built though the existing clang debug info. Sounds pretty neat to access and visualize the inner workings of a C/C++ program as a program which works like an attached debugger.
- athrun 4y agoAsking the HN community: what are the modern options in terms of debugging native programs these days? It seems that this is an area that hasn't seen much progress over the years.
- invalidname 4y agorr is amazing...
- armchairhacker 4y agoWhen I debug, sometimes I write code which pretty-prints the object to stdout, and then execute that inline ("evaluate expression") when I need to. It may be kind of hacky but it works well and it's super easy to implement. As a bonus, you usually end up pretty-printing the object in some debug-logger anyways.
