Getting 256 colors out of ruby-ncurses

阅读更多关于 Getting 256 colors out of ruby-ncurses

问题 I've got 256 colors working great in my terminal (test scripts here), but it stops working when I use ncurses (via Ruby-ncurses). Printing the escape sequences given on that page works fine, but when I initialize ncurses 'puts' stops working and I can't output the colors with any of the various ncurses color changing/string output functions I've found. What gives? 回答1: I am not sure if this would be all the story, but make sure your terminal capabilities do indeed provide for the 256 colors

Ncurses program exits when terminal resized

阅读更多关于 Ncurses program exits when terminal resized

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; } 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 (); sleep (100); endwin (); return 0; } You need to handle the SIGWINCH signal : #include <signal.h> /* resizer

Cannot link ncurses while compiling vim

阅读更多关于 Cannot link ncurses while compiling vim

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 searching for ncurses. It seems -lncurses flag is unavailable, and ldconfig did not help. I do not see

Printing inside window, not on borders

阅读更多关于 Printing inside window, not on borders

问题 I'm trying to write something inside a curses window, but it seems to write on borders too. How can I fix the code below? win_self = newwin(LINES / 2, COLS, 0, 0); box(win_self, 0, 0); wrefresh(win_self); wprintw(win_self, "foobar"); 回答1: In curses, the borders generated by box() are inside borders. As far as I can tell, there's no way to simply say "don't overwrite my border". Nevertheless, there are three solutions that I can think of right now: don't overwrite the border characters (use

using curses with raw_input in python

阅读更多关于 using curses with raw_input in python

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 read sys.stdin.

using ncurses in a virtual terminal

阅读更多关于 using ncurses in a virtual terminal

I'm new to Linux and virtual terminals as well as to Curses, so please forgive me if this description isn't clear as it could be. I'm trying to use Curses on Fedora 12 to output status information to a virtual terminal (you know one of the terminals you can get to by pressing ctrl-alt-Fx). When I start up my application on one of the virtual terminals ($TERM=linux), the lines for the boxes come out as the characters 'j', 'q', 'k'....(and a few other characters). Yet when I start it within a terminal window ($TERM=xterm), everything displays as it should. Can someone explain to me what I need

Ncurses and realtime (implemented in C, unix)

阅读更多关于 Ncurses and realtime (implemented in C, unix)

I am trying to implement a game using ncurses in C. I have to show the current time (the time must update each second) and my while loop looks like this while(1) { clk = time(NULL); cur_time = localtime(&clk); mvprintw(0,1,"%d %d %d",cur_time->tm_hour,cur_time->tm_min,cur_time->tm_sec); int key = getch() //other stuff } My problem is that the time will refresh only when I press a key. Is it a way to make the time refresh without the need of pressing a key (and to implement this in the same while)? There are a couple of functions you could use: nodelay timeout int nodelay(WINDOW *win, bool bf);
