X11 Server

[RossComputerGuy]

I'm trying to build my own x11 server and I've built upon the existing code, but I'm stuck at pack_stream.pack("CxSSSa",[1,11,0,hello.length/4,hello]); and I don't know what hello is suppose to be set to.

What type of server you building? I can't remember how complete server side of this library is, and it does not attempt to implement any functionality/semantics at all, just protocol. Intended use case is various types of proxy servers talking to "Real" x11 server

[sidorares]

looks like you are talking about this line:

node-x11/lib/xserver.js

Line 153 in f040f8b

stream.pack('CxSSSa', [1, 11, 0, hello.length/4, hello]);

( wow, there is hard coded fs.readFile there )

I'm pretty sure this is server side of what happens here:

node-x11/lib/handshake.js

Line 111 in 97a582b

function readServerHello(bl, cb)

Have a look at what readServerHello does on client, from there you can figure out how to serialize that on server

I've not been able to figure it out, I've spent the last few hours looking and couldn't figure it out.

I might be able to help later today but no promices

Here is a chunk of my working code

this.pack_stream.pack("C",[1]);
		this.pack_stream.flush();
		
		this.pack_stream.pack("xSSSLLLLSSCCCCCCCCxxxxp",[
			this.protocolMajor, // major
			this.protocolMinor, // minor
			(32+this.server.formats.getByteLength()+stringPad(this.vendor)+this.server.screens.getByteLength())/4, // xlen
			0, // release
			this.resource_id_base, // resource_base
			this.resource_id_mask, // resource_mask
			255, // motion_buffer_size
			this.vendor.length, // vlen
			0xffff, // max_request_length
			this.server.screens.arr.length, // screen_num
			this.server.formats.arr.length, // format_num
			0, // image_byte_order
			0, // bitmap_bit_order
			32, // bitmap_scanline_unit
			32, // bitmap_scanline_pad
			8, // min_keycode
			255, // max_keycode
			
			this.vendor // vendor
		]);
		this.pack_stream.flush();
		for(var format of this.server.formats.arr) {
			this.pack_stream = format.pack(this.pack_stream);
			this.pack_stream.flush();
		}
		for(var screen of this.server.screens.arr) {
			this.pack_stream = screen.pack(this.pack_stream);
			this.pack_stream.flush();
		}

not much there yet @SpaceboyRoss01 :)
What are you plans re server implementation?

[RossComputerGuy]

I plan to write a basic server that people use event listeners to know what happens.14.11.2018, 14:26, "Andrey Sidorov" <[email protected]>:not much there yet @SpaceboyRoss01 :) What are you plans re server implementation? —You are receiving this because you were mentioned.Reply to this email directly, view it on GitHub, or mute the thread.

Would it actually implement some x server functionality or act as a proxy to "real" server?

[sidorares]

What would it use for display? Offscreen pixmap / browser / etc?

these two use browser:

https://github.com/ttaubert/x-server-js

[RossComputerGuy]

Actually, there's an event that will be emitted when the display is updated.

I might need some help with writing the code to get it to work.
