关于在 Flash Builder 4.5.1 中使用 ANTLR v3 生成的文件的提示 [英] Hints regarding the use of ANTLR v3 generated files in Flash Builder 4.5.1

问题描述

根据这些说明，我正在尝试使用 ANTLR 生成的 *.as 文件在当前 Flash Builder 4.5.1 项目中.

According to these instructions, I'm trying to use ANTLR generated *.as files in a current Flash Builder 4.5.1 project.

因此，我将这个 ANTLR 的 Actionscript 运行时添加到我的项目中 - 没有问题.

Therefore, I added this ANTLR's Actionscript runtime to my project - without problems.

我使用 ANTLRWorks 编译词法分析器/解析器规范也没有问题.

I compiled lexer/parser specs using ANTLRWorks without problems too.

我在源 *.g 文件中添加了语言选项，以使 ANTLR 生成 Actionscript 源:

I added the language option to the source *.g file to make ANTLR generate Actionscript sources:

options {
    backtrack = true; 
    memoize = true;
    k=2;
    output = AST;
    language=ActionScript;        // Added this
    ASTLabelType = CommonTree;
}

不幸的是，ANTLR/ANTLRworks 生成的 Actionscript 代码有问题:

Unfortunately, the ANTLR/ANTLRworks generated Actionscript code is buggy:

Catch 语句读起来像这样 catch (RecognitionException re)，但应该读成这样:catch (re:RecognitionException).

Catch statements read like this catch (RecognitionException re), but should read like this: catch ( re:RecognitionException ).

此外，Flash Builder 在这里抱怨使用 Array:

Furthermore, Flash Builder complains about the use of Array here:

public override function get tokenNames():Array { return PhpParser.tokenNames; }

有人可以确认这些问题并可能提供解决方法的提示吗?

Could anybody confirm these problems and probably provide hints how to solve them?

UPDATE-1

快速浏览一下 ANTLR v3.3 的源代码就会发现这个模板代码 [line 142 @ ActionScript.stg]:

A quick look at the sources of ANTLR v3.3 revealed this template code [line 142 @ ActionScript.stg]:

catch ( re:RecognitionException )

因此，当前的 3.3 分支似乎知道正确的语法.

Thus, the current 3.3 branch seems to know the correct syntax.

不幸的是，当前的 ANTLRworks 1.4.2(包括 3.3 分支)失败了.

Unfortunately, the current ANTLRworks 1.4.2 - which includes the 3.3 branch - fails.

推荐答案

Terence Parr，ANTLR 的项目负责人刚刚确认，ANTLRworks 需要一个新的编译.感谢大力支持！

Terence Parr, the project lead of ANTLR just confirmed, that ANTLRworks needs a new compile. Thanks for great support!
