Debugging

# in terminal #1:
sudo apt install gdbserver
nim c --debugger:native src/moe.nim  # compile binary in folder 'src'
gdbserver :12345 src/moe
# in terminal #2:
gdb src/moe
(gdb) target remote localhost:12345

Now you can use (interact with application) moe in terminal #1, debug (set breakpoint, step, print variable ...) moe in #2.

Or in terminal #2:

cat << EOF > debug.gdb
target remote localhost:12345
b src/moe.nim:35
b src/moepkg/editorstatus.nim:49
b src/moepkg/normalmode.nim:205
b src/moepkg/normalmode.nim:427
EOF

gdb -x debug.gdb
(gdb) c
