问题 This question already has answers here : How to avoid pressing enter with getchar() (11 answers) Closed 3 years ago . I'm writing a C program that prints something on terminal using ncurses. It should stop printing when user press 's' and continue again when press 's'. How can I read a key from input without waiting user to press the key? I tried getch() and getchar() but they wait until a key is pressed... Edit This is my code: int main(void) { initscr(); /* Start curses mode */ refresh(); /

问题 I'd like to create a progress bar to indicate the status of an a batch job in Ruby . I've read some tutorials / libraries on using (n)curses , none of which were particularly helpful in explaining how to create an "animated" progress bar in the terminal or using curses with Ruby . I'm already aware of using a separate thread to monitor the progress of a given job, I'm just not sure how to proceed with drawing a progress bar. Update ProgressBar class was incredibly straight-forward, perfectly

问题 I'm trying to build a project in Xcode but I get errors Implicit declaration of function 'clear' is invalid in C99 and Conflicting types for 'clear' . Here's the code: //main.c #include <stdio.h> #include "tree.h" int main(){ clear(); // Implicit declaration of function 'clear' is invalid in C99 return 0; } //tree.c #include <stdio.h> #include "tree.h" void clear(){ ///Conflicting types for 'clear' printf("Command clear.\n"); } //tree.h #include <stdio.h> void clear(); ///Conflicting types

问题 I am making some assumptions here on technology based on what I know, but other technology recommendations are welcome. My goal: Write an ANSI Art viewer that as closely as possible resembles viewing on a DOS machine as possible, preferably without the overhead of running dosbox. This will run on a Raspberry Pi. I have gotten my console to properly cat an ANSI with proper characters, colors, etc. The catch with the "viewer" is that I would like to be able to use the arrow keys to scroll up

问题 Currently I have an c++ console application running on Win7/AIX/Linux. In the application I use getmaxyx to get the dimensions of the window. getmaxyx(_window, _rows, _cols); On the windows platform i need to play around with the (properties)(layout) options of the running app, to get the screen maximized. That is a bit of a pain. Thumbing through the documention yields nothing of value. lines: Specifies the number of lines the "screen" will have. Directly equates to LINES. There is no

问题 while 1: ... window.addstr(0, 0, 'abcd') window.refresh() ... window size is full terminal size, big enough to hold abcd . If 'abcd' is modified to shorter string like 'xyz' , then on terminal I will see 'xyzd' . What exactly I am doing wrong? 回答1: addstr() only prints the string you specify, it does not clear the following characters. You will have to do that yourself: To clear characters until the end of the line, use clrtoeol(), To clear characters until the end of the window, use clrtobot

问题 I have tried to use python -m pip install windows-curses and the error that shows up is: ERROR: Could not find a version that satisfies the requirement windows-curses (from versions: none) I have also tried the method provided by this answer and the same error shows up in my terminal window. How can I install Curses for Python/Windows 10 on my machine? 回答1: What's your Python version? This library works on 2.7 and 3.5+. I have installed here without problems. I have tested in 3.6 and 3.7 and

问题 Hey there Stack Overflow. I'm trying to build a testing script that should mix outputting changing characters (using curses) on multiple lines (creating them over time), creating new lines based on the thread number. I have the below code: # -*- coding: utf-8 -*- import curses, time, threading def threadedFunction(linePos): stdscr = curses.initscr() curses.noecho() curses.cbreak() try: stdscr.clear() for i in range(50): stdscr.addstr(linePos, 0, "testing %s..." % i) stdscr.refresh() time

问题 I'm writing a program in curses and sometimes happens that if I leave the program opened and I use other terminal tabs for a while, when I go using the program again it seems like it has refreshed something and something has disappeared... I cannot show pics or screenshots because I haven't understood yet well when and how it happens... Is there a way to prevent or fix this? 回答1: screen.getch reads from stdscr , and if it refreshes (due to any change on the screen), will overwrite boxes . You
