I have put some comments. We can discuss this in detail during the meeting today.

+if(XEUS_CPP_USE_DEBUGGER)
+    add_definitions(
+        -DXEUS_CPP_USE_DEBUGGER
+    )
+endif()


Not sure if this is a good idea. I need to know the purpose.

+        std::string m_lldb_port;
+        std::string m_lldbdap_port;


What is the difference between m_lldb_port & m_lldbdap_port?

Looks like m_lldbdap_port is unused?

+    debugger_config["lldb"]["initCommands"] = {
+        "settings set plugin.jit-loader.gdb.enable on"
+    };
+#endif


This does not look correct. The use of ifdef. Let's discuss it in the meeting.
We need to do this based on the metadata of the kernel.json.

+                close(fd);
+            }


Need some explanation here.

This code is used to run lldb-dap and redirect its output to a file. might be useful for debugging

+            {"type", "response"},
+            {"request_seq", message["seq"]},


What is request_seq and message["seq"]?

+                 {"evaluateName", "b"},
+                 {"variablesReference", 0}}}}}}
+        };


I see that this is not yet implemented.

yes, its the major feature to discuss and work upon

+        out << code;

Hopefully, we don't need this.

How and where do you plan to use this?

highlighting lines when breakpoint hit, step ins and outs

Why do we have this?

yeah, i forgot to remove it. i was using previously. no need of this now.
