(For those wishing to use the actual C++ Turbo Vision +library, see [Sergio Sigala's C++ version based on the public domain +sources released by Borland.](http://tvision.sourceforge.net/) ) + +Jexer currently supports three backends: + +* 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 + sequences generated by the library itself: ncurses is not required + or linked to. xterm mouse tracking using UTF8 and SGR coordinates + are supported. For the demo application, this is the default + backend on non-Windows/non-Mac platforms. + +* The same command-line ECMA-48 / ANSI X3.64 type terminal as above, + but to any general InputStream/OutputStream or Reader/Writer. See + the file jexer.demos.Demo2 for an example of running the demo over a + TCP socket. jexer.demos.Demo3 demonstrates how one might use a + character encoding than the default UTF-8. + +* Java Swing UI. This backend can be selected by setting + jexer.Swing=true. The default window size for Swing is 80x25, which + is set in jexer.session.SwingSession. For the demo application, + this is the default backend on Windows and Mac platforms. + +Additional backends can be created by subclassing +jexer.backend.Backend and passing it into the TApplication +constructor. + +The Jexer homepage, which includes additional information and binary +release downloads, is at: https://jexer.sourceforge.io . The Jexer +source code is hosted at: https://github.com/klamonte/jexer . + + + +License +------- + +This project is licensed under the MIT License. See the file LICENSE +for the full license text. + + + +Acknowledgements +---------------- + +Jexer makes use of the Terminus TrueType font [made available +here](http://files.ax86.net/terminus-ttf/) . + + + +Usage +----- + +Simply subclass TApplication and then run it in a new thread: + +```Java +import jexer.*; + +class MyApplication extends TApplication { + + public MyApplication() throws Exception { + super(BackendType.SWING); // Could also use BackendType.XTERM + + // Create standard menus for File and Window + addFileMenu(); + addWindowMenu(); + + // Add a custom window, see below for its code. + addWindow(new MyWindow(this)); + } + + public static void main(String [] args) { + try { + MyApplication app = new MyApplication(); + (new Thread(app)).start(); + } catch (Throwable t) { + t.printStackTrace(); + } + } +} +``` + +Similarly, subclass TWindow and add some widgets: + +```Java +class MyWindow extends TWindow { + + public MyWindow(TApplication application) { + // See TWindow's API for several constructors. This one uses the + // application, title, width, and height. Note that the window width + // and height include the borders. The widgets inside the window + // will see (0, 0) as the top-left corner inside the borders, + // i.e. what the window would see as (1, 1). + super(application, "My Window", 30, 20); + + // See TWidget's API for convenience methods to add various kinds of + // widgets. Note that ANY widget can be a container for other + // widgets: TRadioGroup for example has TRadioButtons as child + // widgets. + + // We will add a basic label, text entry field, and button. + addLabel("This is a label", 5, 3); + addField(5, 5, 20, false, "enter text here"); + // For the button, we will pop up a message box if the user presses + // it. + addButton("Press &Me!", 5, 8, new TAction() { + public void DO() { + MyWindow.this.messageBox("Box Title", "You pressed me, yay!"); + } + } ); + } +} +``` + +Put these into a file, compile it with jexer.jar in the classpath, run +it and you'll see an application like this: + +![The Example Code Above](/screenshots/readme_application.png?raw=true "The application in the text of README.md") + +See the files in jexer.demos for many more detailed examples showing +all of the existing UI controls. The demo can be run in three +different ways: + + * 'java -jar jexer.jar' . This will use System.in/out with + xterm-like sequences on non-Windows platforms. On Windows it will + use a Swing JFrame. + + * 'java -Djexer.Swing=true -jar jexer.jar' . This will always use + Swing on any platform. + + * '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. + + + +More Screenshots +---------------- + +![Several Windows Open Including A Terminal](/screenshots/screenshot1.png?raw=true "Several Windows Open Including A Terminal") + +![Yo Dawg...](/screenshots/yodawg.png?raw=true "Yo Dawg, I heard you like text windowing systems, so I ran a text windowing system inside your text windowing system so you can have a terminal in your terminal.") + + + +System Properties +----------------- + +The following properties control features of Jexer: + + jexer.Swing + ----------- + + Used only by jexer.demos.Demo1. If true, use the Swing interface + for the demo application. Default: true on Windows platforms + (os.name starts with "Windows"), false on non-Windows platforms. + + jexer.Swing.cursorStyle + ----------------------- + + Used by jexer.io.SwingScreen. Selects the cursor style to draw. + Valid values are: underline, block, outline. Default: underline. + + + +Known Issues / Arbitrary Decisions +---------------------------------- + +Some arbitrary design decisions had to be made when either the +obviously expected behavior did not happen or when a specification was +ambiguous. This section describes such issues. + + - See jexer.tterminal.ECMA48 for more specifics of terminal + emulation limitations. + + - TTerminalWindow uses cmd.exe on Windows. Output will not be seen + until enter is pressed, due to cmd.exe's use of line-oriented + input (see the ENABLE_LINE_INPUT flag for GetConsoleMode() and + SetConsoleMode()). + + - TTerminalWindow launches 'script -fqe /dev/null' or 'script -q -F + /dev/null' on non-Windows platforms. This is a workaround for the + C library behavior of checking for a tty: script launches $SHELL + in a pseudo-tty. This works on Linux and Mac but might not on + other Posix-y platforms. + + - Closing a TTerminalWindow without exiting the process inside it + may result in a zombie 'script' process. + + - 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() when using System.in/out. System.out is also + (blindly!) put in 'stty sane cooked' mode when exiting. + + + +Roadmap +------- + +Many tasks remain before calling this version 1.0. See docs/TODO.md +for the complete list of tasks.
