Fcsh Server

I tried to make a wrapper to fcsh. The wrapper will have a socket open so that users can use netcat to talk to it. Possible usage would be like:

$ java FcshServer /opt/adobe/flex/bin/fcsh
$ echo "compile Game.as" | nc localhost 8081

Then FcshServer will see if Game.as has been already compiled. If it has, incremental compilation will be used. So far, I can wrap fcsh and send user inputs to stdin of fcsh and redirect fcsh's stdout to console.

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.InputStreamReader;

public class FcshServer {
    public static void main(String argv[]) throws IOException {

        if(argv.length < 1) {
            System.out.println("Usage: java FcshServer path/to/fcsh");
            System.exit(1);
        }

        //run fcsh
        Process fcsh = new ProcessBuilder(argv).start();

        //redirect stdout of fcsh to here
        OutThread fcshout = new OutThread(fcsh);
        fcshout.start();

        //prepare for read from stdin of this.
        BufferedReader in = new BufferedReader(
                new InputStreamReader(System.in));
        String line = new String("");
        PrintWriter fcshin = new PrintWriter(fcsh.getOutputStream());

        while(fcshout.isAlive() && null != (line = in.readLine())) {
            fcshin.println(line);
            fcshin.flush();
        }

        in.close();
        fcshin.close();
    }
}

class OutThread extends Thread {
    private BufferedReader stdin;
    OutThread(Process p) throws IOException {
        stdin = new BufferedReader(
                new InputStreamReader(p.getInputStream()));
    }

    public void run() {
        int c;
        try {
            while((c = stdin.read()) != -1) {
                System.out.print((char)c);
            }
            System.out.println("Press Enter to exit.");
        } catch(IOException e) {
            e.printStackTrace();
        }
    }
}

I tried to make a wrapper to
[fcsh](http://labs.adobe.com/wiki/index.php/Flex_Compiler_Shell).
The wrapper will have a socket open so that users can use
[netcat](http://netcat.sourceforge.net/) talk to it.

incremental compilation will be used. So far, I can wrap fcsh and send
user inputs to stdin of fcsh and redirect fcsh's stdout to console.
