[antlr-interest] new user adapting java.g from antlr 2.7 for antlr 3.0.1

[Jim Idle]

It means that somewhere you are trying to use both rewrite rules '->' and auto tree building directives such as ! or ^ in a rule. Looks like this is in your atom: rule somewhere. This is an error that will be cleaned up in a future release.

 

However, you should download the 3.0/3.1 examples grammars and use the Java grammar there as this has been recently updated to be 1.5 compatible. 

 

Your other errors may be getting in the way too, regarding the m and t elements. Perhaps you still have m:rule instead of m=rule somewhere?

 

As I said though, abandoning what you have and using the 'official' java grammar for 3.1 (visit the downloads page and download the examples zip/tar)  would seem to be a better bet. You might also find the book a reasonable investment for your company: http://www.pragprog.com/titles/tpantlr

Subject: [antlr-interest] new user adapting java.g from antlr 2.7 for antlr 3.0.1

 

Our company's application development tool uses a scripting language which is very similar to Java (and ultimately generates Java).

I am writing a new editor for it - and the editor depends on a parser.

I am trying to use Antlr 3.0.1 to build a new parser for our language.

I was told to start with a Java 1.1 grammar - or perhaps 1.2, which I finally found in an old downloaded version of Antlr 2.7.

I manually performed the v2->v3 conversions necessary to get most of the grammar upgraded to v3.

Then I added a few of our language constructs. 

Anyhow, I am getting the following errors, and I'm not sure how to resolve them.

Could someone please help me resolve the errors?

 

Thanks,

Chuck
