Problem with debugging the chat example

[Xeneou]

Compiling and running the binaries works fine. However, when I try to debug the code I get a panic on the server side, immediately after the client connects.

Panic:

Run './chat -d /ip4/127.0.0.1/tcp/3001/ipfs/QmcxsSTeHBEfaWBb2QKe5UZWK8ezWJkxJfmcb5rQV374M6' on another console.
 You can replace 127.0.0.1 with public IP as well.

Waiting for incoming connection

> panic: EOF

goroutine 37 [running]:
main.writeData(0xc42043a0c0)
	/home/me/go/Workspace4/src/github.com/libp2p/go-libp2p-examples/chat/chat.go:122 +0x36b

	/home/me/go/Workspace4/src/github.com/libp2p/go-libp2p-examples/chat/chat.go:94 +0x190

Debugger finished with exit code 0

Problems seems to be that the stdReader in writeData() receives no bytes in stdReader.ReadString('\n')

Can somebody explain/reproduce this or has a solution? Debugging would be nice to follow and understand the program's control flow. (Debugging of the echo example works and doesn't cause a panic.)

@Xeneou how exactly are you starting the debugger? (delve)

I has experienced such behavior when I have tried android build, and in my case it was because of android doesn't have an os.StdIn interface for concole direct input.

So, my suggestion is to check interface in stdReader := bufio.NewReader(os.Stdin) in func writeData(rw *bufio.ReadWriter)
