This section describes such issues. + * 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: -Roadmap -------- + * '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. -Many tasks remain before calling this version 1.0: + * 'java -Djexer.Swing=true -jar jexer.jar' . This will always use + Swing on any platform. -0.0.2: + * '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. -- AWT: - - Blinking cursor -- ECMA48Backend running on socket -- TTreeView -- TDirectoryList -- TFileOpen -- Decide on naming convention: getText, getValue, getLabel: one or all - of them? + * '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. -0.0.3: + * 'java -cp jexer.jar jexer.demos.Demo4' . This demonstrates hidden + windows and a custom TDesktop. -- TEditor + * 'java -cp jexer.jar jexer.demos.Demo5' . This demonstrates two + demo applications using different fonts in the same Swing frame. -0.0.4: + * '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. -- Bugs - - TTimer is jittery with I/O - - TSubMenu keyboard mnemonic not working - - Making TMenu keyboard accelerators active/inactive - - TDirectoryList cannot be navigated only with keyboard - - TTreeView cannot be navigated only with keyboard - - RangeViolation after dragging scrollbar up/down + * 'java -cp jexer.jar jexer.demos.Demo7' . This demonstrates the + BoxLayoutManager, achieving a similar result as the + javax.swing.BoxLayout apidocs example. -0.1.0: -- TWindow - - "Smart placement" for new windows -- ECMATerminal - - Mouse 1006 mode parsing -Wishlist features (2.0): +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 +---------------- -- TTerminal - - Handle resize events (pass to child process) - - xterm mouse handling -- Screen - - Allow complex characters in putCharXY() and detect them in putStrXY(). -- TComboBox -- TListBox -- TSpinner -- TCalendar widget -- TColorPicker widget -- Drag and drop - - TEditor - - TField - - TText - - TTerminal - - TComboBox +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 | -Screenshots ------------ +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.
