Shutdown CTRL+C about text-io

[siordache]

Currently, text-io expects only regular text as input. For key combinations such as Ctrl+C the behavior is unspecified and it depends on the underlying TextTerminal implementation.
For Swing, Ctrl+C is by default associated with "copy".
Using Ctrl+C with a SystemTextTerminal or a ConsoleTextTerminal will shut down the JVM.
Note however, that (since version 1.5.0) TextIoFactory usually returns a JLineTextTerminal if System.console() is not null. JLineTextTerminal currently ignores the Ctrl+C, but this behavior can be easily changed by executing: reader.setHandleUserInterrupt(true); I should probably insert this statement in the JLineTextTerminal constructor.

Thanks for explanation, make sense. Although maybe would be nice to have some generic key listener I know that it would be hard for non-GUI console without jna.
For SwingTextTerminal instance for now probably I can just add custom event dispatcher

btw, why the console would forbid closing the window, I would expect that terminal should have common or similar behavior for all implementations ?

I added support for handling user interrupts. For the Swing and the Web text terminal, Ctrl+Q is used by default to trigger a user interrupt. (I didn't use Ctrl+C, because it is usually associated with copy in these environments.) The key combination that triggers a user interrupt can be changed programmatically.
Closing the Swing window will also trigger a user interrupt.

The default user interrupt handler shuts down the JVM. A different handler can be configured by calling registerUserInterruptHandler(). See the commented lines in TextIoDemo for examples.

Implemented in 1.9.0.
Configuration improvements (using terminal properties) in 2.0.0.
