console

问题 I am interested in creating a text-based game in Java and am wondering how I would replicate the common server console (ie: nogui server mode in the minecraft-server for example) - as in there is always a line at the bottom of the console for input, and everything else above it is output which can be written to asynchronously. How would I get started on this? I am unfamiliar with the terminology regarding this sort of stuff and also what libraries to use to begin with. 回答1: You should take a

问题 I am on OSX and I found the following Delphi (Firemonkey) code to write the console output to a Memo. This works fine when I am using normal commands like "ls", but it doesn't capture the output from external terminal apps. For example, if I run the command line application "youtube-dl", the output shows up only in the PAServer log, but not in the Memo. Is there a way to do this? Or can someone modify the code to make this work? const libc = '/usr/lib/libc.dylib'; type PIOFile = Pointer; /

问题 I have int values stored in a list, that I want to output as unicode characters, like this: //A List<int> named Kanji exists and has values Console.OutputEncoding = Encoding.Unicode; int i = 0; while (i < Kanji.Count) { Console.WriteLine((char)Kanji[i]); i++; } But this only returns ? characters. What should I do? The int values themselves are fine, I tested them. 回答1: The console is probably not using a Unicode or Japanese encoding, and/or the font used does not contain the required

问题 I have a small console app. I want to hide its window when it is called from my main program (with -hide as command line parameter) and show it when the user starts it (no command line param).

Purpose: I want my main program to interact with the console app silently in the background (console is invisible). So, when

Using shell:env ? always returns null as the value and I'm not sure if ? is a supported environment variable name in karaf. So how can execute a karaf command if a feature is present? 回答1: It is not possible to test if a feature is

问题 I am trying to add a feature to my C console application calculator that prompts the user to decide whether they want to perform another calculation using: y or n , but in testing, getchar() refuses to wait for input and the program proceeds as though it has received valid input.
