Hallo, Morten. This sounds like a perfect job for a TokenRewriteStream. You should add actions to your grammar that retrieve the start-end token pairs of the portions you need to rewrite and use those in conjunction with TokenRewriteStream's insert/replace/delete methods to perform your modifications, possibly by means of small StringTemplate templates.
See: http://www.antlr.org/api/Java/classorg_1_1antlr_1_1runtime_1_1_token_rewrite_stream.html Cheers, Nicola Musatti Morten Olav Hansen wrote: > Hi > > I'm currently trying to rewrite some java source code, and was looking > for some pointers for doing this.
