ncurses

问题 I tried to enter text at the bottom of window and print it on the top. I did this. But when I resize the window, cursor is attached to the bottom of the window and when I type the text, symbols do not echo on the screen. How fix it? Sorry for my English. my code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ncurses.h> #include <termios.h> #include <sys/ioctl.h> #include <signal.h> WINDOW* txt_win; WINDOW* msg_win; void sig_winch(int in) { struct winsize size; ioctl

问题 I am recently working on a game project using the curses library, and I used color-related functions like start_color() , init_color() and init_pair() . The color works well in my project, but once its used, the colors in other TUI applications like vim will go wrong. For example: When I first edit some part of my code, it is like this: This is vim with colorscheme slate , and it looks good. However, when I run my code and exit and edit the code again, it become something like this: Note: I

问题 I'm writing a small client/server application that uses ncurses as TUI toolkit on the clients. The clients are multithreaded, there is a thread that is used to communicate with the server(via sockets) and a thread that handles the UI. I discovered a bug and I'd like to step through the instructions of the clients to see where the problem lies 1 . Simply running the clients in gdb doesn't work because gdb uses the same terminal as the client, hence the output is all messed up and this makes it

问题 I'm writing a console app in c++ using ncurses and I'd like to output a solid ascii block. It'd basically tape up all of the area that would normally be reserved for white space of a normal character. Is there an ASCII character I'm missing or a library function I haven't seen in the manual? 回答1: ASCII is only 7-bit. If you are willing to go with 8-bit, there is the Code Page 437: http://en.wikipedia.org/wiki/Code_page_437 Then there is Unicode, which opens a whole new world of characters...

问题 I am having a tough time installing R-packages that are not available in the Anaconda repositories. My attempts so far can be found here How to install R-packages not in the conda repositories?. Currently, I am trying to build the R-package rafalib for conda by following the instructions from this article under the heading Building a conda R package . The first part works fine. conda skeleton cran rafalib Out: Tip: install CacheControl to cache the CRAN metadata Fetching metadata from http:/

问题 When i resize my terminal window, the below program exits. Why and how can stop it? #include <ncurses.h> #include <unistd.h> int main () { initscr (); printw ("Some text\n"); refresh (); sleep (100); endwin (); return 0; } 回答1: I found the answer here When terminal has resized, the SIGWINCH signal raises and program exits. Here is the solution: #include <ncurses.h> #include <unistd.h> #include <signal.h> int main () { initscr (); signal (SIGWINCH, NULL); printw ("Some text\n"); refresh ();

问题 I am currently jumping into my first full C++ project and I've run into a hitch with Ncurses. getstr() requires a char array as input, but with this, there is no way to prevent buffer overflow. Lets pretend I'm using this input to get a name. My code would then be the following: int main(){ char* nameTemp = new char[160]; initscr(); getstr(nameTemp); endwin(); delete nameTemp; return 0; } But what happens if the user decides to use more than 160 characters for his name? I get an error and the

问题 In my python linux console application I use curses to handle displaying of data. At the same time I'd like to have an input line to enter commands, pretty much in good ol' irssi-style. With default curses getch() I'd have to do a lot of coding just to get the basic funcionality of raw_input function - arrow keys to move cursor / browse through the input history. Is there a simple way to get such behavior working with curses, as it captures input events and I can't just use functions that

问题 I'm trying to compile vim 7.3 in home directory. As a terminal library, I installed ncurses in ~/lib/ncurses/ncurses-5.9 with --with-shared option. After setting set path = ( ~/lib/ncurses/ncurses-5.9/bin/ $path ) setenv LD_LIBRARY_PATH ~/lib/ncurses/ncurses-5.9/lib/:$LD_LIBRARY_PATH I tried to configure vim with ./configure --enable-multibyte --prefix=/home/******/apps/vim/vim73 or ./configure --enable-multibyte --prefix=/home/******/apps/vim/vim73 --with-tlib=ncurses however it failes while

问题 When I run the following sample code and press just "q", it'll ends properly, but if I pressed any other characters "for instance many breaks and a lot of other characters" and then press "q" it'll not exit, how can I solve this? import curses, time def main(sc): sc.nodelay(1) while True: sc.addstr(1, 1, time.strftime("%H:%M:%S")) sc.refresh() if sc.getch() == ord('q'): break time.sleep(1) if __name__=='__main__': curses.wrapper(main) 回答1: Pressing other keys cause time.sleep(1) call, you
