在eclipse插件中获取行号 [英] get line number within a eclipse Plugin

问题描述

我正在为插件寻找正确的扩展点，以便在编辑器中访问光标位置。目的是在插件视图中为当前的代码行提供其他信息。
我确定这是可能的，因为大纲视图例如突出显示了我现在的功能。
thx

I'm looking for the right extension point for my plugin to access the cursor position in the editor. The aim is to provide additional information to the current code line in a plugin view. I sure it is possible, since the Outline view for example highlights the current function which I'm within. thx

推荐答案

可以使用 textSelection.getOffset（）从您找到的模式，然后使用 org.eclipse.jface.text.IDocument 接口从文档中提取文本，以执行任何您想要的分析。 p>

You can use textSelection.getOffset() from the pattern you've found and then use the org.eclipse.jface.text.IDocument interface to extract text from the document to do whatever analysis you want.

ITextEditor textEditor = (ITextEditor)editor;
IDocumentProvider dp = editor.getDocumentProvider();
IDocument doc = dp.getDocument(editor.getEditorInput());

IDocument 有方法来回转换在字符偏移和行之间。

IDocument has methods to convert back and forth between character offsets and lines.
