Excitement about a new Linux debugger
From 3 comments
This is great to see. It'd be lovely if Linux gets a decent debugger. Another project to keep an eye on is https://github.com/EpicGamesExt/raddebugger Although, they haven't…
tux1968 on HNThis is exciting! I use GDB and LLDB, but their TUIs/CLIs make certain things difficult (I feel like debugging seriously benefits from a proper GUI) and graphical front-ends I've…

Objections
Rewriting gdb is unnecessary; enhancing gdb would be better
From 2 comments
It's not clear to me why we'd need a new debugger instead of GDB enhancements. GDB has an extensible, modern C++ codebase with literal decades of hard earned knowledge baked into…
quotemstr on HNGDB (I don't use LLDB) is fully programmable and has multiple user interfaces (TUI, Emacs, DDD, graphical frontends and various .gdbinit configurations that emulate SoftICE L&F).…

Linux kernel debugging interfaces like ptrace are hard to build on
From 1 comment
This is definitely an ambitious project, and I worry that you are biting off more than you can chew in doing so. (I've attempted my fair share of debugger projects in the past).…

Socket-based control interface
From 1 comment
Nice project! One killer feature would be the ability to connect to the debugger via a socket and control it. Gdb has this interface and for some use cases it's great. As one of…

Questions
Is it built on gdb or gdbserver
From 1 comment
Yay this is awesome! GDB is a buggy (https://sourceware.org/bugzilla/show_bug.cgi?id=18772 https://sourceware.org/bugzilla/show_bug.cgi?id=9425) mess and rough code quality, I've…

Would it work on FreeBSD
From 1 comment
How entwined is it with Linux specific APIs? Eg, how hard would it be to port to FreeBSD?

Alternatives named
gdb and lldb
From 2 comments
> The available Linux debuggers are gdb and lldb. They both suck. They crash all the time, don't understand the data types I care about, and they don't make the data I need…
feelamee on HNEveryone here seems to thing GDB is awful. It's been a while for me but I remember using front-ends like Eclipse's CDT or similar and didn't find that experience so bad. Do most…

rr and Undo
From 2 comments
If you're willing to deal with enterprise pricing, Undo [0] implements something reasonably comparable to rr without the hardware timer requirements. [0] https://undo.io/
AlotOfReading on HNrr should work on any remotely modern Intel system, and generally on AMD's Zen CPUs too. Unless you're in a virtualized environment (some of which are supported) or a more…
