I’m also in favour of keeping the GUI around. It’s not perfect, but at least in 
a usable state and not a huge maintenance burden from what I can see.

 Good day.
 While trying to implement a command in lldb I noticed lldb has this
 awesome `gui` command that opens an ncurses GUI.
 I find it really useful and I wanted to play with it a bit, but I
 wasn't really able to get it working.
 In particular, I tried to press enter on `target create` or `attach`
 but nothing happens.
 
 Greg, as you wrote the original implementation, can you please explain
 how this is supposed to work? Are you actively interested in
 maintaining this mode?
 
 Thanks!

[lldb-dev] Any plan to support to debug Webassembly file?

[Terry Guo via lldb-dev]

Hi there,

I am working on a project which involves compiling C++ source file to
Webassembly byte code file with LLVM. The LLVM works well and can generate
wasm byte code file with DWARF debug sections like .debug_line. I can run
the generated wasm file with my wasm virtual machine. However I find LLDB
doesn't support debugging wasm file. Do we have plan to enable LLDB
debugging wasm file? Thanks for any information.

BR,
Terry

[Raphael “Teemperor” Isemann via lldb-dev]

I’m not sure I understand what the question is. Do you want that LLDB attachs 
to the wasm program running inside your VM and then debug the wasm program via 
LLDB? Or that LLDB can run the wasm module itself like an executable and then 
run it/step through it/inspect it/etc.?

Cheers,

Count me among those who didn't even know it existed - is it even packaged in 
any of the official LLVM (.deb) packages? I haven't noticed it as part of the 
MacPorts ports for LLVM/Clang either...

The GUI is built into lldb, it is not a separate entity.

Oh, right, so a "AUI" or "CUI" rather than something properly graphical. Sorry, 
not very useful to me.

Re: [lldb-dev] Any plan to support to debug Webassembly file?

[Terry Guo via lldb-dev]

Hi Raphael,

Thanks for your recommendation. How about the very first step which
enables LLDB to recognize the wasm bytecode via commands like "lldb
my.wasm" or "file my.wasm" inside lldb? And IMHO the second step is to
enable LLDB to recognize the dwarf sections embedded in wasm bytecode
file. Do you have any suggestion where to start? I searched around and
couldn't find useful instructions/documentations for above two steps.

BR,
Terry
