You need to run your jar file from CLI (command line). Like: java -jar yourJar.jar pause If you want to force this, there are different ways to do this: a shortcut file to CMD and your jar as an argument a batch file running your jar using code like mine above calling it from a … Read more
For eclipse unicode console support: Add -Dfile.encoding=UTF-8 to eclipse.ini which is in the eclipse install directory. In eclipse – Run\Run Configurations\Python Run\configuration\Common\ make sure UTF-8 is selected In eclipse – Window\Preferences\General\Workspace\Text file encoding\ making sure UTF-8 is selected In [python install path]\Lib\site.py – change from encoding = “ascii” to encoding = “utf-8” Make sure you’re … Read more
Yes, it is possible. Get the HWND of the console window using GetConsoleWindow and then draw in it. #define _WIN32_WINNT 0x601 #include <windows.h> #include <stdio.h> int main() { // Get window handle to console, and device context HWND console_handle = GetConsoleWindow(); HDC device_context = GetDC(console_handle); //Here’s a 5 pixels wide RED line [from initial 0,0] … Read more
There’s two problems with the way you’ve defined those API calls. First, the documentation for SetCurrentConsoleFontEx says: lpConsoleCurrentFontEx A pointer to a CONSOLE_FONT_INFOEX structure that contains the font information. So the third parameter needs to be passed by reference: [DllImport(“kernel32.dll”, SetLastError = true)] static extern bool SetCurrentConsoleFontEx( IntPtr consoleOutput, bool maximumWindow, ref CONSOLE_FONT_INFO_EX consoleCurrentFontEx); and … Read more
What you are asking is possible with Readline. There’s a callback where you can get control after the prompt is displayed and insert some text into the read buffer. This worked for me: Readline.pre_input_hook = -> do Readline.insert_text “hello.txt” Readline.redisplay # Remove the hook right away. Readline.pre_input_hook = nil end input = Readline.readline(“Filename: “, false) … Read more
Ok, this was a fun problem. Dosen’t seem to be an elegant way of solving it for all PrintStream methods at once. (Unfortunately there is no FilterPrintStream.) I did write up an ugly reflection-based workaround though (not to be used in production code I suppose 🙂 class LoggedPrintStream extends PrintStream { final StringBuilder buf; final … Read more
You can use format() to format your output according to your need.. for(int i=1; i<13; i++){ for(int j=1; j<13; j++){ System.out.format(“%5d”, i * j); } System.out.println(); // To move to the next line. } Or, you can also use: – System.out.print(String.format(“%5d”, i * j)); in place of System.out.format.. Here’s is the explanation of how %5d … Read more
Your best bet is probably to use the colorama module. In fact, I believe that the Windows console does not support ANSI colors natively. colorama solves this difficulty by intercepting ANSI sequences and performing the appropriate Windows color change calls. This way, your code can be quite portable, as it can print colors in the … Read more
Console.SetCursorPosition, Console.BackgroundColor, Console.ForegroundColor, and Console.ResetColor. Note these were added to the .NET Framework in version 2.0. Prior to that you would have needed PInvoke.
You need to clear the console window AFTER setting the colors but BEFORE you write the text… Console.ForegroundColor = ConsoleColor.Red; Console.BackgroundColor = ConsoleColor.Green; Console.Clear(); Console.WriteLine(“Hello World”); Console.ReadLine();
