Java library for creating text-based GUIs

Lanterna

Lanterna is a Java library allowing you to write easy semi-graphical user interfaces in a text-only environment, very similar to the C library curses but with more functionality. Lanterna is supporting xterm compatible terminals and terminal emulators such as konsole, gnome-terminal, putty, xterm and many more. One of the main benefits of lanterna is that it's not dependent on any native library but runs 100% in pure Java.

Also, when running Lanterna on computers with a graphical environment (such as Windows or Xorg), a bundled terminal emulator written in Swing will be used rather than standard output. This way, you can develop as usual from your IDE (most of them doesn't support ANSI control characters in their output window) and then deploy to your headless server without changing any code.

Lanterna is structured into three layers, each built on top of the other and you can easily choose which one fits your needs best.

1. The first is a low level terminal interface which gives you the most basic control of the terminal text area. You can move around the cursor and enable special modifiers for characters put to the screen. You will find these classes in package com.googlecode.lanterna.terminal.

2. The second level is a full screen buffer, the whole text screen in memory and allowing you to write to this before flushing the changes to the actual terminal. This makes writing to the terminal screen similar to modifying a bitmap. You will find these classes in package com.googlecode.lanterna.screen.

3. The third level is a full GUI toolkit with windows, buttons, labels and some other components. It's using a very simple window management system (basically all windows are modal) that is quick and easy to use. You will find these classes in package com.googlecode.lanterna.gui2.

Maven

Lanterna is available on Maven Central, through Sonatype OSS hosting. Here's what you want to use:

    <dependency>
        <groupId>com.googlecode.lanterna</groupId>
        <artifactId>lanterna</artifactId>
        <version>3.1.2</version>
    </dependency>

Discussions

There is a google group for discussions and announcements related to Lanterna. You are recommended to raise issues directly on Github though.

lanterna's Issues

querySize() doesn't work on OS X (patch included)

The version of the stty program included with OS X is a bit different from the 
one Lantern seems to expect in two ways:

* It uses -f instead of -F to specify the TTY.
* It outputs "40 rows" instead of "rows 40".

Here's a patch that fixes both of these issues so querySize() works properly on 
OS X (at least on Lion): 
https://bitbucket.org/sjl/lanterna/changeset/7a339723fb24

My vanilla Java is a bit rusty, so there's probably a better way to do some of 
that, but at least it's a start.

TextBox can't be used without specifying forceWidth

While testing some components in a small demo-application i tried to use the 
TextBox,i tried using the constructor:

    TextBox(String initialContent)

that is provided in the library,but i find out it cant be used without using 
the constructor:

    TextBox(int forceWidth,String initialContent) 

or it gives a "Exception in thread "main" java.lang.IllegalArgumentException: 
TerminalSize.columns cannot be less than 0! [...]"

To temporally fix the problem i used the other constructor,the one with "int 
forceWidth" specified and it seems to work.

    public TextBox(String initialContent)
    {
        this(-1, initialContent); //this -1 seems to cause the problem
    }

To fix it in a definitive way i took the lanterna sources and modified the line 
(TextBox.java,line 47) and modified the -1 to 0. I hope this may help someone 
:) 
I still not sure it was the right solution,maybe there is something more 
intelligent to do :P !

Can't get screen styles to work with Swing Screen

When using putString with a Swing Screen, the styles like Bold and Underline 
don't seem to get applied -- all the text is normal.  They work fine when I 
swap the Swing screen for a console one.

I'm using OS X 10.7.4 in case that matters.

Visually corrupted characters on Linux

Please see attached screenshot. Characters are mangled as if only the left half 
of them is being drawn. Happens on both the regular terminal (konsole) and via

Could this be a font issue? Bad kerning? Is that being enforced via the 
library? I don't see any font-related methods. Any pointers?

Blocking readInput

Need for setBetweenComponentsPadding in Panel

I found that this was removed in the release 2.1.0. I found there was a padding 
added to the layout manager. I have several panels on a window and to have 
padding between components in the panels I am forced to use a layout manager 
for each panel when I just do without it with just specifying the Orientation. 
Could you get that feature back or have any alternatives?

The Terminal class has a clearScreen() function which is pretty handy, but

needs to be redrawn?

Issue with borders and titles

Hi!

I think I've found two issues with borders. 

First issue: When a panel uses Border.Invisible and a title, the title overlaps 
with the first row of the content. 

Sample code:

    Panel panel = new Panel("Panel");
    panel.setBorder(new Border.Invisible());
    panel.addComponent(new Label("Label 1"));
    panel.addComponent(new Label("Label 2"));
    panel.addComponent(new Label("Label 3"));

Result:

    LaPanel
    Label 2
    Label 3

Expected:

    Label 1
    Label 2
    Label 3

You could argue that the title should still be shown, but if no title is set 
then it looks a little weird. My patch assumes that for an invisible border, 
there is no title. 


Second issue: When a panel uses Border.Standard, the innerAreaLocation and 
innerAreaSize are calculated incorrectly, resulting in the contents being 
pushed down by one line and the last line being truncated. 

Sample code:

    Panel panel = new Panel("Panel");
    panel.setBorder(new Border.Standard());
    panel.addComponent(new Label("Label 1"));
    panel.addComponent(new Label("Label 2"));
    panel.addComponent(new Label("Label 3"));

Result:

    --Panel----
    |         |
    | Label 1 |
    | Label 2 |
    -----------

Expected:

    --Panel----
    | Label 1 |
    | Label 2 |
    | Label 3 |
    -----------

I've attached a patch that resolves these issues. It pushes the responsibility 
for drawing the panel title to the Border, as the title forms part of the 
window decoration rather than the contents. I felt this worked better for the 
invisible border scenario, but I guess it really depends on how you want it to 
work there. 

I also suspect there'll be issues if a panel title exceeds the dimensions of 
the Panel. 

Cheers,
Chris.

The table control could use a scroll bar

Currently when the table cannot accomodate all rows in the screen I am seeing 
an exception similar to the one when adding a checkbox to a table fails. It 
would be useful if the table supported a scroll bar to run through the entries.

Better font detection in SwingTerminal

The SwingTerminal should prefer to use the "monospace" general font and then 
depending on the platform switch to a different one. Defaulting to "Courier 
New" is probably a bad thing.

Bugfix in SwingTerminal resizing

Hi!

I noticed that the SwingTerminal crashes when resized to zero rows and then

ActionListBox could use a scroll bar

It would be nice to have scrollbar for the ActionListBox if it cannot 
accomodate all the elements in the screen. Currently the window just goes blank 
and the listbox seems to just fill up the entire space over the other 
components(I was filling up the listbox in an action event from one of the 
components on the screen).

The selected element in a radiocheckboxlist is incorrect

I see this issue with version 2.0.3. The selectedIndex in the RadioCheckBoxList 
is different from checkedIndex in this case. The checkedIndex value is right. 
But to retrieve the selected element I have to use getSelectedItem() which is 
coming from AbstractListBox. I think the best thing is to override these 
methods and return the checkedIndex when requesting the selectedItemIndex. This 
way getSelectedItem() would return the item selected based on the checkedIndex.

I pulled down the source and am looking through to see how one could implement 
key-chording support but have a couple of questions:

a) are you amenable to receiving patches to this project?
b) what's your workflow like to ensure lack of regressions? I don't see any 
automated test suites that I can run to make sure I'm not introducing bugs and 
I'm not sure that I'd know what to look for in the manual test cases.

TextArea getText()/setText(String text)/append(String text) methods?

I dont know if it's because I've not downloaded the last branch(i still having 
the 2.0.0) but in the TextArea class there aren't the:

getText(),setText(String text) and the append(String text) methods. 

Is this because of the version i have?
I started fixing this adding the methods(just the getText() so far) 
myself(kinda a fast,ugly and wrong work):

    public String getText() { //TODO FIX THE STRING RETURN TO AN ARRAY/ARRAYLIST
        String tmp="";
        if(this.lines != null) {
            for(int i=0;i<this.lines.size();i++) {
                tmp +=" "+this.lines.get(i);
            }
        }
        return tmp;
    }

this fails obviously if the string is too long,so i suggest to DO NOT use this 
solution :)

Hope i helped,somehow or gave u something to work on(I'm sorry I'm posting like 
in a forum hehe) :)

Move or hide cursor for non-text components

I don't think showing the cursor on items like Buttons (which you can't

display in its focused state. Or if the cursor can't be hidden, stick it in the 
corner of the screen where it's less jarring.

Support RGB colors

As far as I can tell from the wiki, there are a limited set of constants to 
represent the different colors. It would be good if we could have access to 
full RGB colors (at least in consoles that support it). For consoles without 
support, either the colors gracefully degrade to the nearest color in the 
minimal set or it is up to the developer to detect the capabilities and adjust 
colors accordingly.

Text not rendering properly

I have a very basic lanterna program but the text is not rendering properly on 
the label. 

Is this my Java settings causing this or something else? Perhaps I need to 
specify something in my code. I have been able to reproduce this with different 
machines and programs.

Thanks,

No information about MacOSX

So far, no computer with MacOSX has been available for testing Lanterna. Tests 
should be carried out and it should be verified whether the Swing terminal 
emulator works or not.

Screen not refreshing until next key press

I've got a program that reads data from network in a separate thread, then adds 
a row to a Table using GuiScreen.runInEventThread. I'd expect that being a 
separate thread it wouldn't have to wait for keyboard input to refresh, but the 
new row doesn't appear until I press a key (any key). Maybe the key reading is 
happening in the wrong (same) thread?

CTRL+D don't work after using lanterna

It seems, after using lanterna in private mode, the keyboard shortcut ctrl+d 
won't work. This has probably something to do with lanterna not properly 
restoring some terminal settings after exiting.
