ncurses

问题 I've looked through the NCurses function list, and I can't seem to find a function that returns the characters already printed on the screen. Is there an accessible value for the char stored in each character cell? If not, is there a similar function in the Windows terminal? I want to use this to replace all the characters on the screen of a certain value (ex: all the a 's) with a different character, or with new attributes. 回答1: The function inch() gets the character and returns it as a

问题 I'm quite new to curses, so I'm trying out some different things in python. I've initialized the window and set scrollok for the window object. I can add strings, and the scrolling works so that addstr() doesn't have any errors at the end of the window. What I'd like to have is the ability to scroll back in the program output in my terminal program (tmux or KDE Konsole, in this case) after the program has finished. In my code, I can at least see the output if I skip the endwin() call, but

问题 Using python I am wanting to have the characters printed out as i type, this is easy in java script, but I am not understanding how to use the curses module, this is the code that I tried but it did not work. import curses stdscr = curses.initscr() curses.echo() curses.cbreak() a = raw_input() print a stdscr.refresh() could you please explain how i use this part of the curses module. 回答1: If you just want to get the user input and make the characters printed out as they are typed, there's not

问题 I need to use ncurses with unicode support, so I included the following line to my .c file. #include <curses.h> In my makefile I'm using -lncursesw as a flag. When calling functions like get_wch(), it tells me "implicit declaration of function". I'm on Arch Linux so I installed ncurses with pacman -S ncurses. In /usr/include I can find cursesw.h, but it doesn't have functions like get_wch() declared. Under /lib I can find libcursesw.so, so what's the matter? 回答1: Use <curses.h> , read the

问题 I want to use libev to listen for keyboard (keystrokes) events in the terminal. My idea is to use (n)curses getch() and set notimeout() (to be nonblocking) to tell getch() not to wait for next keypress. Is there a file descriptor that getch uses I can watch? 回答1: If you use initscr() , the file descriptor you ask for is fileno(stdin) , since the initscr subroutine is equivalent to: newterm(getenv("TERM"), stdout, stdin); return stdscr; If you use newterm(type, outfile, infile) , the file

问题 Where do stdout and stderr go when curses is active? import curses, sys def test_streams(): print "stdout" print >>sys.stderr, "stderr" def curses_mode(stdscr): test_streams() test_streams() curses.wrapper(curses_mode) Actual output is stdout stderr Update0 Expected output is stdout stderr stdout stderr entering, and then exiting curses mode with no change to the final text shown in the terminal. 回答1: Activating curses saves the terminal text screen's current contents and clears said screen;
