custom a command via nvim-dap to load a gdb scripts after attaching to remote not working

[weiyshay]

I am trying debugging C/C++ project via the nvim-dap plugin via different launching modes('launch', 'attach' and 'remote') and it is awesome to see that these three modes work perfectly.

An issue is that I need to load a gdb scripts which is not listed in the default commands in remote mode.
I tried to add it to the command list in the source code but it doesn't make sense.

I added the commands to '.gdbinit' file and it can be invoked from gdb command line properly.

What am I missing? I asked in nvim-dap repo and was recommended to seek for help here.

.gdbinit

define loadscripts 
       printf "loading scripts...\n"
	source test-scripts
end

My configuration:

    -- attach server
    {
        name = 'Attach to gdbserver :3334',
        type = 'cppdbg',
        request = 'launch',

        miDebuggerPath = '/usr/bin/gdb', cwd = '${workspaceFolder}',

            return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
