Nnd – a TUI debugger alternative to GDB, LLDB

Summary

A debugger for Linux. Partially inspired by RemedyBG. Mom, can we have RAD Debugger on Linux? No, we have a debugger at home. Debugger at home: Properties: Fast. TUI. Not based on gdb or lldb, implemented mostly from scratch. Works on large executables. (Tested mostly on 2.5 GB ClickHouse.) What we mean by "fast": Operations that can be instantaneous should be instantaneous. I.e. snappy UI, no random freezes, no long waits. (Known exception: if the program has >~2k threads things become pretty slow. This will be improved.) Operations that can't be instantaneous (loading debug info, searching for functions and types) should be reasonably efficient, multi-threaded, asynchronous, cancellable, and have progress bars. Limitations: Linux only x86 only 64-bit only for native code only (e.g. C++ or Rust, not Java or Python) TUI only (no REPL, no GUI) no remote debugging (but works fine over ssh) single process (doesn't follow forks) no record/replay or backwards stepping Development status: Essential features are there. But different people consider different features essential, and probably many of them are not implemented. Let me know. I use it every day and find it very helpful. Not widely tested - I only tried it on a few machines and a few real executables. Distributed as a single 6 MB executable file with no dependencies.
