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") + License ------- -This library is licensed LGPL ("GNU Lesser General Public License") -version 3 or greater. See the file LICENSE for the full license text, -which includes both the GPL v3 and the LGPL supplemental terms. +Jexer is available to all under the MIT License. See the file LICENSE +for the full license text. + -Usage ------ +Obtaining Jexer +--------------- -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: +Jexer is available on Maven Central: -```Java -import jexer.*; +```xml + + com.gitlab.klamonte + jexer + 0.3.2 + +``` -public class MyApplication extends TApplication { +Binary releases are available on SourceForge: +https://sourceforge.net/projects/jexer/files/jexer/ - public MyApplication() { - super(); +The Jexer source code is hosted at: https://gitlab.com/klamonte/jexer - // Create an editor window that has support for - // copy/paste, search text, arrow keys, horizontal - // and vertical scrollbar, etc. - addEditor(); - // Create standard menus for File and Window - addFileMenu(); - addWindowMenu(); - } - public static void main(String [] args) { - MyApplication app = new MyApplication(); - app.run(); - } -} -``` +Documentation +------------- +* [Java API Docs](https://jexer.sourceforge.io/apidocs/api/index.html) -Roadmap -------- +* [Wiki](https://gitlab.com/klamonte/jexer/wikis/home) + +* [Jexer web page](https://jexer.sourceforge.io/) + + + +Programming Examples +-------------------- + +The examples/ folder currently contains: + + * A [prototype tiling window + manager](/examples/JexerTilingWindowManager.java) in less than 250 + lines of code. + + * A much slicker [prototype tiling window + manager](/examples/JexerTilingWindowManager2.java) in less than 200 + 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. + + * 'java -cp jexer.jar jexer.demos.Demo7' . This demonstrates the + BoxLayoutManager, achieving a similar result as the + javax.swing.BoxLayout apidocs example. + + + +More Screenshots +---------------- + +Jexer can be run inside its own terminal window, with support for all +of its features including images and mouse, and more terminals: + +![Yo Dawg...](/screenshots/jexer_sixel_in_sixel.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.") + +Sixel output uses a single palette which works OK for a variety of +real-world images: + +![Sixel Pictures Of Cliffs Of Moher And Buoy](/screenshots/sixel_images.png?raw=true "Sixel Pictures Of Cliffs Of Moher And Buoy") + +The color wheel with that palette is shown below: + +![Sixel Color Wheel](/screenshots/sixel_color_wheel.png?raw=true "Sixel Color Wheel") + + + +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 | CLI, X11, Windows | yes | yes | yes | +| mlterm | X11 | yes | yes | yes | +| RLogin | Windows | yes | yes | yes | +| alacritty(3) | X11 | yes | yes | no | +| gnome-terminal | X11 | yes | yes | no | +| iTerm2 | Mac | yes | yes | no(5) | +| kitty(3) | X11 | yes | yes | no | +| lcxterm(3) | CLI, Linux console | yes | yes | no | +| mintty | Windows | yes | yes | no(5) | +| rxvt-unicode | X11 | yes | yes | no(2) | +| xfce4-terminal | X11 | yes | yes | no | +| aminal(3) | X11 | yes | no | no | +| konsole | X11 | yes | no | no | +| yakuake | X11 | yes | no | no | +| Windows Terminal(6) | Windows | no | no | no(2) | +| screen | CLI | yes(1) | yes(1) | no(2) | +| tmux | CLI | yes(1) | yes(1) | no | +| putty | X11, Windows | yes | no | no(2) | +| Linux | Linux console | no | no | no(2) | +| qodem(3) | CLI, Linux console | yes | yes(4) | 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. + +5 - Sixel images can crash terminal. + +6 - Version 0.4.2382.0, on Windows 10.0.18362.30.
