JavaCup to Antlr grammar translator?

[rla...@basis.com]

Hi,

I'm a newbie to language definitions, parsing, etc., but like antlr, intuitively, and bought the Antlr 4 Reference book to get my feet wet.

The company I work for has a domain specific language defined a long time ago in JavaCup format that I would like to convert to antlr, so I can look at it using antlrworks, for example. It is rather large and appears to me to be pretty complex. So that I don't have to learn the cup format, does anyone know of a grammar translator that could help me convert at least a bulk of it to antlr?

Thank you.

I suggest that you don't start with something as large as this - pick out a few easy to parse languages and write grammars from scratch.

I don't think that there are any converters, but if you first produce a few simple grammars from scratch, I think that you would find it easier to write a CUP input file grammar, then from that create your own converter - this would teach you a lot more than trying to slog through a manual conversion and you would have a more accurate translation in the end.

Have you managed to find or write a toold to convert a JavaCUP file to an ANTLR file? right now I'm desperate to get one.

thankyou

Unfortunately, no and my priorities (not my interest!) have taken me away from pursuing this further at this time.
