如何在eclipse编辑器插件中显示语法错误 [英] How to show syntax errors in an eclipse editor plugin

问题描述

在eclipse编辑器中，如何在eclipse编辑器中指示语法错误（例如，令牌的非法序列），即可以通过红色箭头下划线，滚动条上的红色标记，您可以跳转到当您将鼠标悬停在任何一个中时，您会发现解释性消息？

我正在为自定义文件格式（特别是Shark3D游戏的snake文件格式）编写一个eclipse编辑器插件发动机）。我已经实现了一个扫描器来获取语法高亮和大纲。

• 对于下划线，我只需让扫描仪返回一个 IToken wriggly underline TextAttribute 而不是正常的，还是有一个特殊的机制来标记语法错误？


• 如何实现滚动条标记？是否有 IAnnotationModel 相关界面？如果是这样，我在哪里注册实现，以便标记出现？


• 我只找到 SourceViewerConfiguration.getAnnotationHover（），这将允许我实现悬停行为，但只有注释，我认为是滚动条标记 - 如何实现文本本身的悬停行为？

我会快乐的具体建议以及涵盖这一点的教程的网址 - eclipse帮助文档和示例似乎没有。

编辑：
标记是最好的解决方案。有关如何使用它们的工作示例可以在 org.eclipse.ui.examples.readmetool.AddReadmeMarkerAction

解决方案

你应该使用标记。

从Java开发人员Eclipse指南派生的示例如下：

 < extension point =org.eclipse.core.resources.markers
 id =snakesyntax
 name =Snake syntax error> 
< super type =org.eclipse.core.resources.problemmarker/> 
< super type =org.eclipse.core.resources.textmarker/> 
< persistent value =true/> 
< extension> 
 
 IMarker marker = res.createMarker（com.ibm.tool.resources.snakesyntax）; 
 
 marker.setAttribute（IMarker.SEVERITY，0）; 
 marker.setAttribute（IMarker.CHAR_START，startOfSyntaxError）; 
 marker.setAttribute（IMarker.CHAR_END，endOfSyntaxError）; 
 marker.setAttribute（IMarker.LOCATION，Snake file）; 
 marker.setAttribute（IMarker.MESSAGE，Syntax error）; 
  

How can I indicate syntax errors (e.g. an illegal sequence of tokens) in an eclipse editor plugin just like in the eclipse Java editor, i.e. by red wriggly underlines, a red marker on the scrollbar that you can jump to, and an explanatory message when you hover over either one?

I'm writing an eclipse editor plugin for a custom file format (specifically, the "snake file format" of the Shark3D game engine). I have implemented a scanner to get syntax highlighting, and an outline.

• For the underlines, do I simply have the scanner return an IToken with a "wriggly underline" TextAttribute instead of the normal one, or is there a specific mechanism for marking syntax errors?
• How do I implement the scrollbar markers? Is IAnnotationModel the relevant interface here? If so, where do I register the implementation so that the markers appear?
• I've only found SourceViewerConfiguration.getAnnotationHover(), which would allow me to implement the hover behaviour, but only for the "annotation", which I suppose means the scrollbar markers - how do I implement the hover behaviour for the text itself?

I'd be happy specific advice as well as an URL of a tutorial that covers this - the eclipse help documents and examples don't seem to.

Edit: Markers are the best solutions to this. A working example of how to use them can be found in the plugin example code in org.eclipse.ui.examples.readmetool.AddReadmeMarkerAction

解决方案

You should be using Markers.

An example derived from "The Java Developer's Guide to Eclipse" follows:

<extension point="org.eclipse.core.resources.markers"  
            id="snakesyntax"  
            name="Snake syntax error">  
    <super type="org.eclipse.core.resources.problemmarker" />  
    <super type="org.eclipse.core.resources.textmarker" />  
    <persistent value="true" />
<extension>

IMarker marker = res.createMarker("com.ibm.tool.resources.snakesyntax");

marker.setAttribute(IMarker.SEVERITY, 0);
marker.setAttribute(IMarker.CHAR_START, startOfSyntaxError);
marker.setAttribute(IMarker.CHAR_END, endOfSyntaxError);
marker.setAttribute(IMarker.LOCATION, "Snake file");
marker.setAttribute(IMarker.MESSAGE, "Syntax error");
