If you want to use Clang tools (e.g. clangd via kak-lsp) to hack on Kakoune's C++ sources. you'll need to create acompile_commands.json file so the Clang tool will use the correct build flags.

One solution is to wrap yourmake invocations withbear:

bear -- make debug=yes clean all

Another solution is toteach the build system to outputcompile_commands.json.

For debugging interactive scenarios that don't have tests yet you can usegdbserver:

gdbserver :2345 ./kak; reset

(If Kakoune crashes, it might not be able to reset terminal modes. Thereset takes care of that.)

Then, connect togdbserver from another terminal

gdb -ex 'target remote :2345'

Since this is a remote target, gdbserver will by default fail to pick up pretty printers (for both stdlib and Kakoune types).To fix this, add this to your~/.gdbinit (or tosrc/.gdbinit):

    set sysroot
