如何让退格  在 Eclipse 的控制台中工作? [英] How to get backspace  to work in Eclipse's console?

问题描述

我正在创建一个小的 Java 应用程序，它应该有一个带有百分比的进度指示器.在每个循环中，它使用退格键  在显示下一个百分比之前删除显示的进度.

I'm creating a little Java application which should have a progress indicator with percentages. In every loop it uses backspace  to remove the displayed progress before displaying the next percentage.

这是一个简化的例子:

public static void main(String[] args) throws Exception {
    System.out.print("Progress: ");
    for (int percentage = 0; percentage < 100; percentage++) {
        System.out.print(percentage + "%");
        Thread.sleep(10); // Stub for "long running task".
        int length = String.valueOf(percentage).length() + 1;
        while (length-- > 0) {
            System.out.print('');
        }
    }
    System.out.println("finished!");
}

这在命令提示符下运行良好，但在 Eclipse 的控制台(Galileo build 20090920-1017)中无法识别退格字符.而是显示一个表示未知字符的空方块.看截图:

This works perfectly in command prompt, but the backspace character isn't recognized in Eclipse's console (Galileo build 20090920-1017). It instead displays an empty square denoting an unknown character. See screenshot:

如何让 Eclipse 正确显示"退格键?IE.让它删除前一个字符.

How do I get Eclipse to "display" the backspace properly? I.e. let it remove the previous character.

这实际上不是什么showstopper，因为它只会在命令控制台中运行，但是让它在Eclipse中也能工作会很好:)

This is actually no showstopper since it will just be run in command console, but it would be just nice to get it to work in Eclipse as well :)

Eclipse Bug#76936. 我不会指望他们来修复它，并且没有列出任何解决方法.
