如何从Eclipse PDE中的活动编辑器获取文本 [英] How to get text from active editor in Eclipse PDE

问题描述

我有一个处理程序，我想在该处理程序中从工作台中的活动编辑器获取文本。从下面的屏幕快照中，我想将所有内容都保存在Test.java（公共类Test ...）中。

I have a handler in which I would like to get the text from the active editor in my workbench. From the screenshot below, I would like to get everything inside of Test.java ("public class Test...").

我已成功在源菜单下添加了新命令。只是不确定现在从何处从活动编辑器获取文本。到目前为止，这是我尝试获取文本的内容（它只是在弹出窗口中显示文件名）：

I've added a new command under the "Source" menu successfully. Just not sure where to get the text from the active editor now. Here's what I have so far in my attempt to get the text (it's just displaying the file name in a popup):

package generatebuilderproject.handlers;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.handlers.HandlerUtil;
import org.eclipse.jface.dialogs.MessageDialog;

public class GenerateBuilderHandler extends AbstractHandler {

    public GenerateBuilderHandler() {
    }

    public Object execute(ExecutionEvent event) throws ExecutionException {
        IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
        IEditorPart editorPart = HandlerUtil.getActiveEditor(event);

        MessageDialog.openInformation(
                window.getShell(),
                "GenerateBuilderProject",
                editorPart.getEditorInput().getName());
        return null;
    }
}

推荐答案

拥有 IEditorPart 后，您可以尝试以下操作：

Once you have the IEditorPart, you can try the following:

IEditorInput input = editorPart.getEditorInput();
if (input instanceof FileEditorInput) {
    IFile file = ((FileEditorInput) input).getFile();
    InputStream is = file.getContents();
    // TODO get contents from InputStream
}
