Jexer - Java Text User Interface library
========================================
-This library is currently in design, but when finished it is intended
-to implement a text-based windowing system loosely reminiscient of
-Borland's [Turbo Vision](http://en.wikipedia.org/wiki/Turbo_Vision)
-library. For those wishing to use the actual C++ Turbo Vision
-library, see [Sergio Sigala's updated
-version](http://tvision.sourceforge.net/) that runs on many more
-platforms.
+This library implements a text-based windowing system loosely
+reminiscent of Borland's [Turbo
+Vision](http://en.wikipedia.org/wiki/Turbo_Vision) system. It looks
+like this:
+
+![Terminal, Image, Table](/screenshots/new_demo1.png?raw=true "Terminal, Image, Table")
+
+Jexer works on both Xterm-like terminals and Swing, and supports
+images in both Xterm and Swing. On Swing, images are true color:
+
+![Swing Snake Image](/screenshots/snake_swing.png?raw=true "Swing Snake Image")
+
+On Xterm, images are dithered to a common palette:
+
+![Xterm Snake Image](/screenshots/snake_xterm.png?raw=true "Xterm Snake Image")

+Jexer is available to all under the MIT License. See the file LICENSE

-Usage
------
-The library is currently under initial development, usage patterns are
-still being worked on. Generally the goal will be to build
-applications somewhat as follows:
+Obtaining Jexer
+---------------
-```Java
-import jexer.*;
+Jexer is available on Maven Central:
-public class MyApplication extends TApplication {
+```xml
+<dependency>
+ <groupId>com.gitlab.klamonte</groupId>
+ <artifactId>jexer</artifactId>
+ <version>0.3.1</version>
+</dependency>
+```
- public MyApplication() {
- super();
+Binary releases are available on SourceForge:
+https://sourceforge.net/projects/jexer/files/jexer/
- // Create an editor window that has support for
- // copy/paste, search text, arrow keys, horizontal
- // and vertical scrollbar, etc.
- addEditor();
+The Jexer source code is hosted at: https://gitlab.com/klamonte/jexer
- // Create standard menus for File and Window
- addFileMenu();
- addWindowMenu();
- }
- public static void main(String [] args) {
- MyApplication app = new MyApplication();
- app.run();
- }
-}

+Documentation

-Roadmap
--------
+* [Java API Docs](https://jexer.sourceforge.io/apidocs/api/index.html)
+
+* [Wiki](https://gitlab.com/klamonte/jexer/wikis/home)
+
+
+
+Programming Examples
+--------------------
+
+The examples/ folder currently contains:
+
+ * A [prototype tiling window
+ manager](/examples/JexerTilingWindowManager.java) in less than 250
+ lines of code.
+
+ * A [prototype image thumbnail
+ viewer](/examples/JexerImageViewer.java) in less than 350 lines of
+ code.
+
+jexer.demos contains official demos showing all of the existing UI
+controls. The demos can be run as follows:
+
+ * 'java -jar jexer.jar' . This will use System.in/out with
+ Xterm-like sequences on non-Windows non-Mac platforms. On Windows
+ and Mac 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 Xterm backend
+ on a telnet server that will update with screen size changes.
+
+ * 'java -cp jexer.jar jexer.demos.Demo3' . This will use
+ System.in/out with Xterm-like sequences. One can see in the code
+ how to pass a different InputReader and OutputReader to
+ TApplication, permitting a different encoding than UTF-8.
+
+ * 'java -cp jexer.jar jexer.demos.Demo4' . This demonstrates hidden
+ windows and a custom TDesktop.
+
+ * 'java -cp jexer.jar jexer.demos.Demo5' . This demonstrates two
+ demo applications using different fonts in the same Swing frame.
+
+ * 'java -cp jexer.jar jexer.demos.Demo6' . This demonstrates two
+ applications performing I/O across three screens: an Xterm screen
+ and Swing screen, monitored from a third Swing screen.

+Terminal Support

+
+The table below lists terminals tested against Jexer's Xterm backend:
+
+| Terminal | Environment | Mouse Click | Mouse Cursor | Images |
+| -------------- | ------------------ | ----------- | ------------ | ------ |
+| xterm | X11 | yes | yes | yes |
+| jexer(3) | CLI, X11, Windows | yes | yes | yes |
+| mlterm | X11 | yes | yes | yes |
+| lcxterm(3) | CLI, Linux console | yes | yes | no |
+| rxvt-unicode | X11 | yes | yes | no(2) |
+| alacritty(3) | X11 | yes | yes | no |
+| gnome-terminal | X11 | yes | yes | no |
+| xfce4-terminal | X11 | yes | yes | no |
+| aminal(3) | X11 | yes | no | no |
+| konsole | X11 | yes | no | no |
+| yakuake | X11 | yes | no | no |
+| screen | CLI | yes(1) | yes(1) | no(2) |
+| tmux | CLI | yes(1) | yes(1) | no |

+| qodem-x11(3) | X11 | yes | no | no |
+| yaft | Linux console (FB) | no | no | yes |
+
+1 - Requires mouse support from host terminal.
+
+2 - Also fails to filter out sixel data, leaving garbage on screen.
+
+3 - Latest in repository.
+
+4 - Requires TERM=xterm-1003 before starting.
