pollInput
public KeyStroke pollInput()
Description copied from interface:InputProvider
Returns the nextKey
off the input queue or null if there is no more input events available. Note, this method call is not blocking, it returns null immediately if there is nothing on the input stream.- Specified by:
pollInput
in interfaceInputProvider
- Specified by:
pollInput
in interfaceIOSafeTerminal
- Returns:
- Key object which represents a keystroke coming in through the input stream
-
readInput
public KeyStroke readInput()
Description copied from interface:InputProvider
Returns the nextKey
off the input queue or blocks until one is available. NOTE: In previous versions of Lanterna, this method was not blocking. From lanterna 3, it is blocking and you can callpollInput()
for the non-blocking version.- Specified by:
readInput
in interfaceInputProvider
- Specified by:
readInput
in interfaceIOSafeTerminal
- Returns:
- Key object which represents a keystroke coming in through the input stream
-
enterPrivateMode
public void enterPrivateMode()
Description copied from interface:Terminal
Calling this method will, where supported, give your terminal a private area to use, separate from what was there before. Some terminal emulators will preserve the terminal history and restore it when you exit private mode. Some terminals will just clear the screen and put the cursor in the top-left corner. Typically, if you terminal supports scrolling, going into private mode will disable the scrolling and leave you with a fixed screen, which can be useful if you don't want to deal with what the terminal buffer will look like if the user scrolls up.- Specified by:
enterPrivateMode
in interfaceIOSafeTerminal
- Specified by:
enterPrivateMode
in interfaceTerminal
-
exitPrivateMode
public void exitPrivateMode()
Description copied from interface:Terminal
If you have previously entered private mode, this method will exit this and, depending on implementation, maybe restore what the terminal looked like before private mode was entered. If the terminal doesn't support a secondary buffer for private mode, it will probably make a new line below the private mode and place the cursor there.- Specified by:
exitPrivateMode
in interfaceIOSafeTerminal
- Specified by:
exitPrivateMode
in interfaceTerminal
-
clearScreen
public void clearScreen()
Description copied from interface:Terminal
Removes all the characters, colors and graphics from the screen and leaves you with a big empty space. Text cursor position is undefined after this call (depends on platform and terminal) so you should always callmoveCursor
next. Some terminal implementations doesn't reset color and modifier state so it's also good practise to callresetColorAndSGR()
after this.- Specified by:
clearScreen
in interfaceIOSafeTerminal
- Specified by:
clearScreen
in interfaceTerminal
-
clearBackBuffer
private void clearBackBuffer()
Clears out the back buffer and the resets the visual state so next paint operation will do a full repaint of everything
-
setCursorPosition
public void setCursorPosition(int x, int y)
Description copied from interface:Terminal
Moves the text cursor to a new location on the terminal. The top-left corner has coordinates 0 x 0 and the bottom- right corner has coordinates terminal_width-1 x terminal_height-1. You can retrieve the size of the terminal by calling getTerminalSize().- Specified by:
setCursorPosition
in interfaceIOSafeTerminal
- Specified by:
setCursorPosition
in interfaceTerminal
- Parameters:
x
- The 0-indexed column to place the cursor aty
- The 0-indexed row to place the cursor at
-
setCursorPosition
public void setCursorPosition(TerminalPosition position)
Description copied from interface:Terminal
Same as callingsetCursorPosition(position.getColumn(), position.getRow())
- Specified by:
setCursorPosition
in interfaceIOSafeTerminal
- Specified by:
setCursorPosition
in interfaceTerminal
- Parameters:
position
- Position to place the cursor at
-
getCursorPosition
public TerminalPosition getCursorPosition()
Description copied from interface:Terminal
Returns the position of the cursor, as reported by the terminal. The top-left corner has coordinates 0 x 0 and the bottom-right corner has coordinates terminal_width-1 x terminal_height-1.- Specified by:
getCursorPosition
in interfaceIOSafeTerminal
- Specified by:
getCursorPosition
in interfaceTerminal
- Returns:
- Position of the cursor
-
setCursorVisible
public void setCursorVisible(boolean visible)
Description copied from interface:Terminal
Hides or shows the text cursor, but not all terminal (-emulators) supports this. The text cursor is normally a text block or an underscore, sometimes blinking, which shows the user where keyboard-entered text is supposed to show up.- Specified by:
setCursorVisible
in interfaceIOSafeTerminal
- Specified by:
setCursorVisible
in interfaceTerminal
- Parameters:
visible
- Hides the text cursor iffalse
and shows it iftrue
-
putCharacter
public void putCharacter(char c)
Description copied from interface:Terminal
Prints one character to the terminal at the current cursor location. Please note that the cursor will then move one column to the right, so multiple calls toputCharacter
will print out a text string without the need to reposition the text cursor. If you reach the end of the line while putting characters using this method, you can expect the text cursor to move to the beginning of the next line.You can output CJK (Chinese, Japanese, Korean) characters (as well as other regional scripts) but remember that the terminal that the user is using might not have the required font to render it. Also worth noticing is that CJK (and some others) characters tend to take up 2 columns per character, simply because they are a square in their construction as opposed to the somewhat rectangular shape we fit latin characters in. As it's very difficult to create a monospace font for CJK with a 2:1 height-width proportion, it seems like the implementers back in the days simply gave up and made each character take 2 column. It causes issues for the random terminal programmer because you can't really trust 1 character = 1 column, but I suppose it's "しょうがない". If you try to print non-printable control characters, the terminal is likely to ignore them (all
Terminal
implementations bundled with Lanterna will).- Specified by:
putCharacter
in interfaceIOSafeTerminal
- Specified by:
putCharacter
in interfaceTerminal
- Parameters:
c
- Character to place on the terminal
-
putString
public void putString(java.lang.String string)
Description copied from interface:Terminal
Prints a string to the terminal at the current cursor location. Please note that the cursor will then move one column to the right, so multiple calls toputString
will print out a text string without the need to reposition the text cursor. If you reach the end of the line while putting characters using this method, you can expect the text cursor to move to the beginning of the next line.You can output CJK (Chinese, Japanese, Korean) characters (as well as other regional scripts) but remember that the terminal that the user is using might not have the required font to render it.

If you try to print non-printable control characters, the terminal is likely to ignore them (all
Terminal
implementations bundled with Lanterna will).You can use this method to place emoji characters on the terminal, since they take up more than one char with Java's built-in UTF16 encoding.

- Parameters:
string
- String to place on the terminal

newTextGraphics
public TextGraphics newTextGraphics()
Description copied from interface:Terminal
Creates a new TextGraphics object that uses this Terminal directly when outputting. Keep in mind that you are probably better off to switch to a Screen to make advanced text graphics more efficient. Also, this TextGraphics implementation will not call.flush()
after any operation, so you'll need to do that on your own.- Specified by:
newTextGraphics
in interfaceTerminal
- Returns:
- TextGraphics implementation that draws directly using this Terminal interface
-
enableSGR
public void enableSGR(SGR sgr)
Description copied from interface:Terminal

setForegroundColor
public void setForegroundColor(TextColor color)
Description copied from interface:Terminal
Changes the foreground color for all the following characters put to the terminal. The foreground color is what color to draw the text in, as opposed to the background color which is the color surrounding the characters.This overload is using the TextColor class to define a color, which is a layer of abstraction above the three different color formats supported (ANSI, indexed and RGB). The other setForegroundColor(..) overloads gives you direct access to set one of those three.
Note to implementers of this interface, just make this method call color.applyAsForeground(this);
- Specified by:
setForegroundColor
in interfaceIOSafeTerminal
- Specified by:
setForegroundColor
in interfaceTerminal
- Parameters:
color
- Color to use for foreground
-
setBackgroundColor
public void setBackgroundColor(TextColor color)
Description copied from interface:Terminal
Changes the background color for all the following characters put to the terminal. The background color is the color surrounding the text being printed.This overload is using the TextColor class to define a color, which is a layer of abstraction above the three different color formats supported (ANSI, indexed and RGB). The other setBackgroundColor(..) overloads gives you direct access to set one of those three.
Note to implementers of this interface, just make this method call color.applyAsBackground(this);

- Specified by:
setBackgroundColor
in interfaceTerminal
- Parameters:
color
- Color to use for the background
-
getTerminalSize
public TerminalSize getTerminalSize()
Description copied from interface:Terminal
Returns the size of the terminal, expressed as aTerminalSize
object. Please bear in mind that depending on theTerminal
implementation, this may or may not be accurate. See the implementing classes for more information. Most commonly, calling getTerminalSize() will involve some kind of hack to retrieve the size of the terminal, like moving the cursor to position 5000x5000 and then read back the location, unless the terminal implementation has a more smooth way of getting this data. Keep this in mind and see if you can avoid calling this method too often. There is a helper class, SimpleTerminalResizeListener, that you can use to cache the size and update it only when resize events are received (which depends on if a resize is detectable, which they are not on all platforms).- Specified by:
getTerminalSize
in interfaceIOSafeTerminal
- Specified by:
getTerminalSize
in interfaceTerminal
- Returns:
- Size of the terminal
-
enquireTerminal
public byte[] enquireTerminal(int timeout, java.util.concurrent.TimeUnit timeoutUnit)
Description copied from interface:Terminal
Retrieves optional information from the terminal by printing the ENQ (\u005) character. Terminals and terminal emulators may or may not respond to this command, sometimes it's configurable.- Specified by:
enquireTerminal
in interfaceIOSafeTerminal
- Specified by:
enquireTerminal
in interfaceTerminal
- Parameters:
timeout
- How long to wait for the talk-back message, if there's nothing immediately available on the input stream, you should probably set this to a somewhat small value to prevent unnecessary blockage on the input stream but large enough to accommodate a round-trip to the user's terminal (~300 ms if you are connection across the globe).timeoutUnit
- What unit to use when interpreting thetimeout
parameter- Returns:
- Answer-back message from the terminal or empty if there was nothing
-
bell
public void bell()
Description copied from interface:Terminal
Prints 0x7 to the terminal, which will make the terminal (emulator) ring a bell (or more likely beep). Not all terminals implements this. Wikipedia has more details.- Specified by:

- Specified by:
flush
in interfaceTerminal
-
close
public void close()
Description copied from interface:Terminal
Closes the terminal, if applicable. If the implementation doesn't support closing the terminal, this will do nothing. The Swing/AWT emulator implementations will translate this into a dispose() call on the UI resources, the telnet implementation will hang out the connection.- Specified by:

addResizeListener
public void addResizeListener(TerminalResizeListener listener)
Description copied from interface:Terminal
Adds aTerminalResizeListener
to be called when the terminal has changed size. There is no guarantee that this listener will really be invoked when the terminal has changed size, at all depends on the terminal emulator implementation. Normally on Unix systems the WINCH signal will be sent to the process and lanterna can intercept this.There are no guarantees on what thread the call will be made on, so please be careful with what kind of operation you perform in this callback. You should probably not take too long to return.
