Both LLDB and GDB can't print slice content ([]T). Is there a way to debug zig programs as convenient as C programs?

use .ptr

I know I can do x foo.ptr and stuff but it's not that convenient

#

foo[0] doesn't work

The lldb pretty printers support slices

#

and allow frame variable slice[5].field just fine

#

the gdb pretty printers look like they have support, but I haven't used them

is there any update on this? I'm wondering if zig has a sanctioned debugger or one that is known to work well

#

gdb or lldb with the pretty printers from the link jacobly posted

#

I believe most of the core team uses lldb now

#

So the lldb pretty printers are more up to date and complete

if you're on windows, windbg preview seems to display slices properly in the watch window
visual studio and vscode don't for whatever reason 🤷
