curses

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 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 I have a program which needs to output three messages that are constantly changing. Number of connections, time elapsed, and refused connections. I tried writing them with '\r' at the end of the string and printed newlines before the other ones started their own output loops thinking the return carriage goes back one line. but they all ended up in the first line overwriting each other. I've seen similar questions and people were recommending using curses but i can't seem to get it to work. I

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;

问题 I have a program I'm writing to better understand ncurses, and when I push it through valgrind , it outputs many leaks associated with ncurses commands. However, I only use stdscr , and call endwin() at the end of main() . I have user options set by using menu.h, and use free_item and free_menu at the end: menuChoice(WINDOW* scr, std::vector<std::string> *choices, std::string desc) { //create the menu and the item pointer vector MENU* my_menu; std::vector<ITEM*> my_items; ITEM* cur = NULL;

问题 My LAME (v3.99.5) outputs progress in console by moving up x lines in the console and overwriting the previous lines. It's pretty cool. I've read in a different post that such behavior for a single line can be achieved with a mere "\r" instead of "\n" - although the post was for Ruby, it seems to be the same for C on my system at least: #include <stdio.h> #include <time.h> int main() { time_t t; time_t t2; time(&t); t2 = t; printf("%u\r", (unsigned int)t); fflush(stdout); while (1) { if (t2 -
