Antlr4 grammar missing

[stevej2608]

Hi,

The Antlr 4 grammar file is missing from the source tree. The derived A4 lexer & parser are in cymbol.jar but I cannot find the associated grammar.

Can you upload the grammar so the project can be built using the latest version of Antlr 4.

Thanks, Steve

Hi Steve,

The grammar file is located here:

https://github.com/ttiimm/cymbol/blob/master/src/cymbol/compiler/Cymbol.g

Let me know if there is anything else I could help with.

Hi Tim,

Thanks for getting back. The Cymbol.g grammar is Antlr 3 not Antlr 4. The Antlr parser contained in cymbol.jar is an A4 parser so I figured it must have been generated from an A4 grammar (Cymbol.g4?).

I now know it's easy enough to convert the A3 grammar to A4 which is what I've done. As Terence Parr says "basically you just delete anything the A4 generator complains about". I was just worried that you might have enhanced/improved the grammar. If so I would not be able to pick up these changes.

Cheers, Steve

Ah OK. I wrote the grammar while Antlr was in a beta version. I don't recall which version though. But it was in Spring 2012 semester. I haven't had time to update with the latest release.
