Question

我正在努力开发一个简单的Eclipse plugin,以了解它是如何运作的。

我对此有两个问题:

我怎么能了解现任编辑的内容?

是否有关于生命周期的好文件? 我无法在谷歌找到真正的好的文件。

Answer 1

关于现任编辑的内容,有几种方式可以做到这一点。未测试以下代码:

public String getCurrentEditorContent() {
    final IEditorPart activeEditor = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage()
            .getActiveEditor();
    if (activeEditor == null)
        return null;
    final IDocument doc = (IDocument) activeEditor.getAdapter(IDocument.class);
    if (doc == null) return null;

    return doc.get();
}

Answer 2

Tonny Madsen的回答是罚款的,但也许更加透明(植被(植被)非常不透明)。

public String getCurrentEditorContent() {
    final IEditorPart editor = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage()
        .getActiveEditor();
    if (!(editor instanceof ITextEditor)) return null;
    ITextEditor ite = (ITextEditor)editor;
    IDocument doc = ite.getDocumentProvider().getDocument(ite.getEditorInput());
    return doc.get();
}

Answer 3

I m assuming you re already familiar with using Eclipse as an IDE.

Create a new plug-in project using the New Plug-in Project Wizard.
On the Templates panel, choose "Plug-in with an editor"
Read the generated code

If you re serious about writing Eclipse plug-ins, the book, "Eclipse Plug-ins" by Eric Clayberg and Dan Rubel is invaluable. I couldn t make sense of the eclipse.org write-ups until after I read the book.
