High level architecture
|

=======================
|
||||
|

## Direct terminal sharing
|
||||
|
||||
No proxy needed. `tty-share` will start a command, and be ready to serve it's output and input over WS connections.

||||

||||

|

+------------+
|
||||
```
|
||||
|
||||
- the `tty-share` opens a TCP connection to the `tty-proxy`
|
||||
- the `tty-proxy` proxy accepts the connection, generates a session ID, and sends it back to `tty-share`
|
||||
- there is now a direct connection between the two
|
||||
- a session ID to map any web connections to the `tty-share` side
|
||||
Alice wants to share a terminal session with Bob, so she starts `tty-share` on her machine, inside the terminal. `tty-share` then connects to the `tty-server` and starts inside a `bash` process. It then puts the terminal in which it was started in RAW mode, and the stdin and stdout are multiplexed to/from the `bash` process it started, and the remote connection to the `tty-server`. On the server side, a session is created, which connects the `tty-share` connection with the future `tty-receiver` instances, running in the browser. The `tty-receiver` runs inside the browser, on top of [xterm.js](https://xtermjs.org/), and is served by the server, via a unique session URL. Alice has to send this unique URL to Bob.
|
||||
|
||||
- `tty-share` gets http requests:
|
||||
- `/` (direct, from a listening server): serves the `index.html` - templated for direct requests (e..g: `<script src="/static/tty-receiver.js"></script>`)
|
||||
- `/` (via the `tty-proxy` TCP connection): serves the `index.html` - templated for the respective session (it already has the session). (e.g.: `<script src="<id>/static/tty-receiver.js"></script>`)
|
||||
- `/ws/` (direct, from the listening server): accepts a WS connection and connects it to the command opened
|
||||
- `/ws/` (via the `tty-proxy` TCP connection): accepts a WS connection and connects it to the command opened
|
||||
Once the connection is established, Bob can then interact inside the browser with the `bash` session started by Alice. When Bob presses, for example, the key `a`, this is detected by `xterm.js` and sent via a websockets connection to the server side. From there, it is sent to the `tty-share` which sends it to the pseudo terminal attached to the `bash` process started inside `tty-share`. Then character `a` is received via the standard output of the `bash` command, and is sent from there both to the standard output of the `tty-share`, so Alice can see it, and also to the `tty-receiver` (via the server), so Bob can see it too.
|
||||
|
||||
- `tty-proxy` gets HTTP requests:
|
||||
- `/s/<id>/*` - builds a HTTP request forwards it to the TCP connection it has to the `tty-share` for that `<id>`
|
||||
- `/ws/<id>` - forwards the WS connection to the `tty-share`, over the *same* TCP connection as above
|
||||
|
||||
- over the same TCP connection, we have to pass multiple requests + a WS connection

# Old version
|
||||
|
||||
The old version of tty-share was working on a different architecture. The `tty-share` command was smaller, and the [tty-server](https://github.com/elisescu/tty-server) was serving the browser code. I decided to change that and make the server side simpler so it only forwards data back and forth, acting exactly like a reverse proxy. The only difference between `tty-proxy` and a reverse proxy, is that it doesn't create the connections to the target by itself, but instead it's the target (the `tty-share` command) that create the TCP connection over which then the connections are proxied to.
|
||||
|
||||
The two main reasons for this change are:
|
||||
1. **non public sessions**: if you want to share a terminal session only in the local network, that is now possible. For this to work, the `tty-share` command has to contain all the browser code too.
|
||||
2. **decoupling** between the public server and the `tty-share` so the user sharing is always in control of what code will end up running in the browser, without relying on the server. This makes backwards compatibility easier to maintain, at least for the browser sessions.
|
||||
|
||||
This change also means that:
|
||||
* the [tty-server]() is now deprecated, and `tty-proxy` should be used instead. I reflected on whether I should have kept the same name or not, but I felt that using a different one might avoid confusion, given that they are two completely different applications.
|
||||
* you will need to use the latest version of the `tty-share` that works with this new architecture.

# Proxy
|
||||
|
||||
`tty-share` will open a `TCP` connection to a public proxy.
|
||||
|
||||
This proxy will act like a reverse proxy, but it will not open new connections to any new back
|
||||
server, and instead it will simulate multiple multiplexed connections over the `TCP` connection
|
||||
already opened by `tty-share` mentioned above.
|
||||
|
||||
The proxy will be completely dumb. It will only proxy connections coming from client browsers to the
|
||||
`tty-share`. It will be the `tty-share` command that will serve the content, and the ws
|
||||
connections. Any SSL/WSS from the web clients will be terminated by nginx or other typical reverse
|
||||
proxy.

# go-ansiterm
|
||||
|
||||
This is a cross platform Ansi Terminal Emulation library. It reads a stream of Ansi characters and produces the appropriate function calls. The results of the function calls are platform dependent.
|
||||
|
||||
For example the parser might receive "ESC, [, A" as a stream of three characters. This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU). The parser then calls the cursor up function (CUU()) on an event handler. The event handler determines what platform specific work must be done to cause the cursor to move up one position.
|
||||
|
||||
The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png). There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
|
||||
|
||||
See parser_test.go for examples exercising the state machine and generating appropriate function calls.

||||
|
||||
func main() {
|
||||
c := exec.Command("grep", "--color=auto", "bar")
|
||||
f, err := pty.Start(c)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
|
