Xtext和ANTLR之间有什么关系? [英] What's the relationshiop between Xtext and ANTLR?

问题描述

我听说Xtext最终使用了ANTLR，但是它们的语法规范文件具有一些不同的格式.那么两者之间是什么关系?

I heard that Xtext ultimately uses ANTLR but their grammar specification files have somewhat different formats. So what's the relationship between the two?

推荐答案

Xtext依靠Antlr解析器生成器来解析输入文件.最重要的是，该框架提供了许多附加值，例如强类型的AST，用于链接和静态分析的抽象以及针对Eclipse的IDE集成.

Xtext relies on the Antlr parser generator for the parsing of input files. On top of that the framework provides lot's of added value such as strongly typed ASTs, abstractions for linking and static analysis as well as IDE integration for Eclipse.

为此，Xtext生成两个Antlr语法.一个用于生产实际AST的生产解析，另一个用于消费事件以为Eclipse编辑器计算内容建议的语法.

For that purpose, Xtext generates two Antlr grammars. One for the production parsing where the actual AST is produced, and a second grammar that is used to consume events to compute the content proposals for the Eclipse editor.
