-Some arbitrary design decisions had to be made when either the
-obviously expected behavior did not happen or when a specification was
-ambiguous. This section describes such issues.
-
- - TTerminalWindow will hang on input from the remote if the
- TApplication is exited before the TTerminalWindow's process has
- closed on its own. This is due to a Java limitation/interaction
- between blocking reads (which is necessary to get UTF8 translation
- correct) and file streams.
-
- - See jexer.tterminal.ECMA48 for more specifics of terminal
- emulation limitations.
-
- - TTerminalWindow uses cmd.exe on Windows. Output will not be seen
- until enter is pressed, due to cmd.exe's use of line-oriented
- input (see the ENABLE_LINE_INPUT flag for GetConsoleMode() and
- SetConsoleMode()).
-
- - TTerminalWindow launches 'script -fqe /dev/null' on non-Windows
- platforms. This is a workaround for the C library behavior of
- checking for a tty: script launches $SHELL in a pseudo-tty. This
- works on Linux but might not on other Posix-y platforms.
-
- - Java's InputStreamReader as used by the ECMA48 backend requires a
- valid UTF-8 stream. The default X10 encoding for mouse
- coordinates outside (160,94) can corrupt that stream, at best
- putting garbage keyboard events in the input queue but at worst
- causing the backend reader thread to throw an Exception and exit
- and make the entire UI unusable. Mouse support therefore requires
- a terminal that can deliver either UTF-8 coordinates (1005 mode)
- or SGR coordinates (1006 mode). Most modern terminals can do
- this.
-
- - jexer.session.TTYSession calls 'stty size' once every second to
- check the current window size, performing the same function as
- ioctl(TIOCGWINSZ) but without requiring a native library.
-
- - jexer.io.ECMA48Terminal calls 'stty' to perform the equivalent of
- cfmakeraw() when using System.in/out. System.out is also
- (blindly!) put in 'stty sane cooked' mode when exiting.
