Class UnixTerminal
- ConsoleOperations
public class UnixTerminal
Terminal that is used for unix platforms. Terminal initialization
is handled by issuing the stty command against the
/dev/tty file to disable character echoing and enable
character input. All known unix systems (including
Linux and Macintosh OS X) support the stty), so this
implementation should work for an reasonable POSIX system.

UnixTerminal
public UnixTerminal()
checkBackspace
protected void checkBackspace()
getSttyCommand
public static String getSttyCommand()
The command to use to set the terminal options. Defaults
to "stty", or the value of the system property "jline.sttyCommand".
getTerminalHeight
public int getTerminalHeight()
Returns the value of "stty size" height param.
Note: this method caches the value from the
first time it is called in order to increase speed, which means
that changing to size of the terminal will not be reflected
in the console.
- getTerminalHeight in interface Terminal
getTerminalWidth
public int getTerminalWidth()
Returns the value of "stty size" width param.
Note: this method caches the value from the
first time it is called in order to increase speed, which means
that changing to size of the terminal will not be reflected
in the console.
- getTerminalWidth in interface Terminal
initializeTerminal
public void initializeTerminal()
throws IOException,
InterruptedException
Remove line-buffered input by invoking "stty -icanon min 1"
against the current terminal.
- initializeTerminal in interface Terminal
readVirtualKey
public int readVirtualKey(InputStream in)
throws IOException
- readVirtualKey in interface Terminal
restoreTerminal
public void restoreTerminal()
throws Exception
Restore the original terminal configuration, which can be used when
shutting down the console reader. The ConsoleReader cannot be
used after calling this method.
setSttyCommand
public static void setSttyCommand(String cmd)
The command to use to set the terminal options. Defaults
to "stty", or the value of the system property "jline.sttyCommand".
