I have tried to be as complete as possible. If there are functions you need that are not included, please let me know and/or send me some diffs. There are 3 basic types exported by this module: 1) Screen - This is not currently used 2) Window - This is the basic type. This is equivalent to "WINDOW *". 3) Pad - This is similar to Window, but works with Pads as defined in curses. Most of the routines can be looked up using the curses man page. Here is a list of the currently supported methods and attributes in the curses module: Return Value Func/Attr Description -------------------------------------------------------------------------- StringObject version A string representing the current version of this module. WindowObject initscr() This initializes the screen for use None endwin() Closes down the screen and returns things as they were before calling initscr() True/FalseObject isendwin() Has endwin() been called? None doupdate() Updates screen WindowObject newwin(nlines,ncols,begin_y,begin_x) newwin(begin_y,begin_x) newwin() creates and returns a new window. None beep() Beep the screen if possible None flash() Flash the screen if possible None ungetch(int) Push the int back so next getch() will return it. Note: argument is an INT, not a CHAR None flushinp() Flush all input buffers None cbreak() Enter cbreak mode None nocbreak() Leave cbreak mode None echo() Enter echo mode None noecho() Leave echo mode None nl() Enter nl mode None nonl() Leave nl mode None raw() Enter raw mode None noraw() Leave raw mode None intrflush(int) Set or reset interruptable flush mode, int=1 if set, 0 if notset. None meta(int) Allow 8 bit or 7 bit chars. int=1 is 8 bit, int=0 is 7 bit StringObject keyname(int) return the text representation of a KEY_ value. (see below) Here is a list of the currently supported methods and attributes in the WindowObject: Return Value Func/Attr Description -------------------------------------------------------------------------- None refresh() Do refresh None nooutrefresh() Mark for refresh but wait None mvwin(new_y,new_x) Move Window None move(new_y,new_x) Move Cursor WindowObject subwin(nlines,ncols,begin_y,begin_x) subwin(begin_y,begin_x) None addch(y,x,ch,attr) addch(y,x,ch) addch(ch,attr) addch(ch) None insch(y,x,ch,attr) insch(y,x,ch) insch(ch,attr) insch(ch) None delch(y,x) delch() None echochar(ch,attr) echochar(ch) None addstr(y,x,str,attr) addstr(y,x,str) addstr(str,attr) addstr(str) None attron(attr) None attroff(attr) None attrset(sttr) None standend() None standout() None border(ls,rs,ts,bs,tl,tr,bl,br) (accepts 0-8 INT args) None box(vertch,horch) vertch and horch are INTS box() None hline(y,x,ch,n) hline(ch,n) None vline(y,x,ch,n) vline(ch,n) None erase() None deleteln() None insertln() (y,x) getyx() (y,x) getbegyx() (y,x) getmaxyx() None clear() None clrtobot() None clrtoeol() None scroll() None touchwin() None touchline(start,count) IntObject getch(y,x) getch() StringObject getstr(y,x) getstr() IntObject inch(y,x) inch() None clearok(int) int=0 or int=1 None idlok(int) int=0 or int=1 None leaveok(int) int=0 or int=1 None scrollok(int) int=0 or int=1 None setscrreg(top,bottom) None keypad(int) int=0 or int=1 None nodelay(int) int=0 or int=1 None notimeout(int) int=0 or int=1 ******************************************************************/ /* curses module */ #include "Python.h" #ifdef HAVE_NCURSES_H /* Now let's hope there aren't systems that have a broken ncurses.h */ #include #else #include #endif typedef struct { PyObject_HEAD SCREEN *scr; } PyCursesScreenObject; typedef struct { PyObject_HEAD WINDOW *win; WINDOW *parent; } PyCursesWindowObject; typedef struct { PyObject_HEAD WINDOW *pad; } PyCursesPadObject; #if 0 staticforward PyTypeObject PyCursesScreen_Type; #endif staticforward PyTypeObject PyCursesWindow_Type; #if 0 staticforward PyTypeObject PyCursesPad_Type; #endif #define PyCursesScreen_Check(v) ((v)->ob_type == &PyCursesScreen_Type) #define PyCursesWindow_Check(v) ((v)->ob_type == &PyCursesWindow_Type) #define PyCursesPad_Check(v) ((v)->ob_type == &PyCursesPad_Type) /* Defines */ static PyObject *PyCursesError; /* For exception curses.error */ /* Catch-all error messages */ static char *catchall_ERR = "curses function returned ERR"; static char *catchall_NULL = "curses function returned NULL"; /* Tells whether initscr() has been called to initialise curses */ static int initialised = FALSE; #define ARG_COUNT(X) \ (((X) == NULL) ? 0 : (PyTuple_Check(X) ?

Reworked arg parsing where variable arg lists are used. Generate exceptions when ERR or NULL is returned by curses functions. Changed return types to match SysV Curses manual descriptions. Added keypad() to window method list. Added border(), hline() and vline() window methods. Version 1.1: 94/08/31: Minor fixes given by Guido. Changed 'ncurses' to 'curses' Changed '__version__' to 'version' Added PyErr_Clear() where needed Moved ACS_* attribute initialization to PyCurses_InitScr() to fix crash on SGI Version 1.0: 94/08/30: This is the first release of this software.
