Class Console

Object

Console

public class Console
extends Object

Non-GUI handling of System.out and System.err redirection.

Be careful when debugging this class, because if it's throwing exceptions, don't take over System.err, and debug while watching just System.out or just call println() or whatever directly to systemOut or systemErr.

Also note that encodings will not work properly when run from Eclipse. This means that if you use non-ASCII characters in a println() or some such, the characters won't print properly in the Processing and/or Eclipse console. It seems that Eclipse's console-grabbing and that of Processing don't get along with one another. Use 'ant run' to work on encoding-related issues.

Method Detail

startup

public static void startup()

setEditor

public static void setEditor(OutputStream out,
                             OutputStream err)

systemOut

public static void systemOut(String what)

systemErr

public static void systemErr(String what)

shutdown

public static void shutdown()

Close the streams so that the temporary files can be deleted.

File.deleteOnExit() cannot be used because the stdout and stderr files are inside a folder, and have to be deleted before the folder itself is deleted, which can't be guaranteed when using the deleteOnExit() method.
