I'm trying to build a class that I can use like the expect command in tcl.
I'm having trouble building a nonblocking readline().
I'm working with the example shell.java. I have a good connection and I
receive no errors.
channel.connect();
byte[] tmp=new byte[1024];
while(true){
while(in.available()>0){
int i=in.read(tmp, 0, 1024);
if(i<0)break;
System.out.print(new String(tmp, 0, i));
}
if(channel.isClosed()){
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){}
}
If I use BufferedReader, it blocks on the last line. I have no good way to test
if the lastline has a \r.
If I use InputStream, I'm building readline from the ground up. I need to keep
track of every char I read.
Java Streams and channels are a weak spot for me.
Can a nonblocking readline be build into the channel class?
What about a look ahead buffer?
