@lxo the #GDB mailing list seemed inactive, and Arsen: on IRC mentioned this as your idea for an #LSP server, so ...
[ Big fan, especially of your linux-libre work
and your stint on the FSF board ]
As a #Cpp dev, it is a sorry state - impotent ctags/etags/global on one side, the overkill that is ccls on the other. I came round to DWARF debuginfo as a reliable source, but not wanting to build off libelf myself ... and to your idea apparently, of using GDB itself as a langserver.
Over.
fraid I don't know, I only came up with that possibility when asked to briefly look into what it would take to implement it in GCC, where I didn't think it would fit. I figured GDB had the full-program context it would take, unlike GCC, that sees one translation unit at a time, and that was the extent of my involvement. if anything came out of it, I probably wasn't told, but if I was, I forgot. FWIW, I haven't ever interacted with a language server, this was all an exercise of imagination many years ago.
@lxo great! Is GDB-as-static-langserver an active effort? I'd settle for an inferior gdb in Emacs as an xref backend first ...
