从java中的插件中的控制台获取输入 [英] Taking input from console in a plugin in java

问题描述

我正在开发一个Eclipse插件，我想从用户那里获取输入。我有一个问题，在处理控制台，因为我有2个控制台1在原来的Eclipse应用程序和另一个在新打开的Eclipse插件窗口。我使用下面显示的方法在控制台打印插件

I am developing an Eclipse plugin and I want to take input from the user. I had a problem before with dealing with the console as I have 2 consoles 1 in the original Eclipse application and the other in the new opened Eclipse plugin window. I used the method shown below to print in the Console of the Plugin

public static void writeToConsole(String output) {

        MessageConsole console = new MessageConsole("My Console", null);
        console.activate();
        ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[]{ console });
        MessageConsoleStream stream = console.newMessageStream();
        stream.println(output);
    }

我只是不知道如何在控制台中写，在变量

I just don't know how to write in the console and take what's written in a variable

NB中
正常的方法如

BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
        String s = bufferRead.readLine();


    System.out.println(s);

适用于原始的Eclipse而不是插件 b $ b

推荐答案

您不能绑定UI等待用户输入，因此您必须在接收到用户输入时处理。一种方法是使用文档侦听器。下面是打印输入的最后一行的示例：

You can't tie up the UI waiting for user input so you have to handle user input when it is received. One way to do this is with a document listener. Here is an example that prints the last line typed:

        console.getDocument().addDocumentListener(new IDocumentListener() {
            @Override
            public void documentChanged(final DocumentEvent event) {
                if ("\r\n".equals(event.getText())) {
                    final IDocument doc = event.getDocument();
                    try {
                        final IRegion region = doc.getLineInformationOfOffset(event.getOffset());
                        try {
                            final String line = doc.get(region.getOffset(), region.getLength());
                            System.out.println(line);
                        } catch (BadLocationException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                    } catch (BadLocationException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }
            @Override
            public void documentAboutToBeChanged(final DocumentEvent event) {
                // TODO Auto-generated method stub                    
            }
        });
