This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection.

# FindNcursesw
|
|
# ------------
|
|
#
|
|
# Find the ncursesw (wide ncurses) include file and library.
|
|
#
|
|
# Based on FindCurses.cmake which comes with CMake.
|
|
#
|
|
# Checks for ncursesw first. If not found, it then executes the
|
|
# regular old FindCurses.cmake to look for for ncurses (or curses).

# Result Variables
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module defines the following variables:
|
|
#
|
|
# ``CURSES_FOUND``
|
|
# True if curses is found.
|
|
# ``NCURSESW_FOUND``
|
|
# True if ncursesw is found.
|
|
# ``CURSES_INCLUDE_DIRS``
|
|
# The include directories needed to use Curses.
|
|
# ``CURSES_LIBRARIES``
|
|
# The libraries needed to use Curses.
|
|
# ``CURSES_HAVE_CURSES_H``
|
|
# True if curses.h is available.
|
|
# ``CURSES_HAVE_NCURSES_H``
|
|
# True if ncurses.h is available.
|
|
# ``CURSES_HAVE_NCURSES_NCURSES_H``
|
|
# True if ``ncurses/ncurses.h`` is available.
|
|
# ``CURSES_HAVE_NCURSES_CURSES_H``
|
|
# True if ``ncurses/curses.h`` is available.
|
|
# ``CURSES_HAVE_NCURSESW_NCURSES_H``
|
|
# True if ``ncursesw/ncurses.h`` is available.
|
|
# ``CURSES_HAVE_NCURSESW_CURSES_H``
|
|
# True if ``ncursesw/curses.h`` is available.
|
|
#
|
|
# Set ``CURSES_NEED_NCURSES`` to ``TRUE`` before the
|
|
# ``find_package(Ncursesw)`` call if NCurses functionality is required.
