晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

C++ interface to ncurses routines
-----------------------------------------------------------------------
This directory contains the source code for several C++ classes which
ease the use of writing ncurses-based programs. The code was originally
derived from the libg++ CursesWindow class, but rewritten for ncurses.
The classes simplify the use of window specific functions by
encapsulating them in the window object. Function overloading is
used in order to narrow the interface. For example, you do not have the
distinction between `printw' and `mvprintw' anymore.
A second benefit is the removal of all #defines which are included in
the curses.h file. This is a steady cause of trouble because many
common identifiers are used. Instead now all #defines are inline
functions, which also allows strict type checking of arguments.
The next enhancement is color support. It was originally provided by a
derived class. This caused some trouble if you think about Panels or
Menus and Forms with colors. We decided to put color support into the
base class so that any derived class may use color support also.
The implementation chosen here is directed to unrestricted use
of mixes of color and monochrome windows. The original NCursesColorWindow
class is maintained for compatibility reasons.
The last point to mention is the support of other packages that are
distributed with the ncurses package: the panels library, the menu library
and the form library. This support is provided by the NCursesPanel class,
which is also derived from the NCursesWindow class and the NCursesMenu
and NCursesForm classes which are derived from NCursesPanel. This allows
building interfaces with windows.
Please see the example program for a quick introduction.
Note that at this point, there is no documentation for these classes.
Hopefully some will be written in the not too distant future. For now,
to find out how to use the classes, read the code and the example program.
Suggestions for enhancements and contributions of code (and docs) are
welcome. Please let us know which functionality you miss.
