		-- if you change `runInTerminal` to true, you might need to change the yama/ptrace_scope setting:
		--
		--    echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
		--
		-- Otherwise you might get the following error:
		--
		--    Error on launch: Failed to attach to the target process

		-- But you should be aware of the implications:
