Sigala's updated version](http://tvision.sourceforge.net/) that runs
on many more platforms.
-Two backends are available:
+Three backends are available:
* System.in/out to a command-line ECMA-48 / ANSI X3.64 type terminal
(tested on Linux + xterm). I/O is handled through terminal escape
are supported. For the demo application, this is the default
backend on non-Windows platforms.
+* The same command-line ECMA-48 / ANSI X3.64 type terminal as above,
+ but to any general InputStream/OutputStream. See the file
+ jexer.demos.Demo2 for an example of running the demo over a TCP
+ socket.
+
* Java Swing UI. This backend can be selected by setting
jexer.Swing=true. The default window size for Swing is 132x40,
which is set in jexer.session.SwingSession. For the demo
application, this is the default backend on Windows platforms.
-The demo application showing the existing UI controls is available via
-'java -jar jexer.jar' or 'java -Djexer.Swing=true -jar jexer.jar' .
+The demo application showing the existing UI controls can be seen in
+three ways:
+
+ * 'java -jar jexer.jar' . This will use System.in/out on
+ non-Windows, or Swing on Windows.
+
+ * 'java -Djexer.Swing=true -jar jexer.jar' . This will always use
+ Swing.
+
+ * 'java -cp jexer.jar jexer.demos.Demo2 PORT' (where PORT is a
+ number to run the TCP daemon on). This will use the telnet
+ protocol to establish an 8-bit clean channel and be aware of
+ screen size changes.
Additional backends can be created by subclassing
jexer.backend.Backend and passing it into the TApplication

obviously expected behavior did not happen or when a specification was
ambiguous. This section describes such issues.
- TTerminalWindow
- ---------------
-
- TTerminalWindow will hang on input from the remote if the
TApplication is exited before the TTerminalWindow's process has
closed on its own. This is due to a Java limitation/interaction
checking for a tty: script launches $SHELL in a pseudo-tty. This
works on Linux but might not on other Posix-y platforms.
- ECMA48 Backend
- --------------
-
- - Java's InputStreamReader requires a valid UTF-8 stream. The
- default X10 encoding for mouse coordinates outside (160,94) can
- corrupt that stream, at best putting garbage keyboard events in
- the input queue but at worst causing the backend reader thread to
- throw an Exception and exit and make the entire UI unusable.
- Mouse support therefore requires a terminal that can deliver
- either UTF-8 coordinates (1005 mode) or SGR coordinates (1006
- mode). Most modern terminals can do this.
-
- Use of 'stty'
- -------------
+ - Java's InputStreamReader as used by the ECMA48 backend requires a
+ valid UTF-8 stream. The default X10 encoding for mouse
+ coordinates outside (160,94) can corrupt that stream, at best
+ putting garbage keyboard events in the input queue but at worst
+ causing the backend reader thread to throw an Exception and exit
+ and make the entire UI unusable. Mouse support therefore requires
+ a terminal that can deliver either UTF-8 coordinates (1005 mode)
+ or SGR coordinates (1006 mode). Most modern terminals can do
+ this.
- jexer.session.TTYSession calls 'stty size' once every second to
check the current window size, performing the same function as
ioctl(TIOCGWINSZ) but without requiring a native library.
- jexer.io.ECMA48Terminal calls 'stty' to perform the equivalent of
- cfmakeraw(). The terminal is (blindly!) put back in 'stty sane
- cooked' mode when exiting.
+ cfmakeraw() when using System.in/out. System.out is also
+ (blindly!) put in 'stty sane cooked' mode when exiting.

System Properties
Many tasks remain before calling this version 1.0:
-0.0.2: STABILIZE EXISTING
-
-- ECMA48Backend running on socket
-
0.0.3: FINISH PORTING
-- TTreeView
- - Also add keyboard navigation
- TDirectoryList
- Also add keyboard navigation
- TFileOpen
+ - Also add keyboard navigation
0.0.4: NEW STUFF
0.0.5: BUG HUNT
- TSubMenu keyboard mnemonic not working
+- Swing performance. Even with double buffering it isn't great.
0.1.0: BETA RELEASE
