[stringtemplate-interest] Automatic generation of "StringTemplate"s from antlr grammar?

[Terence Parr]

Hi Anthony,

Well, yes, you can automatically generate templates but the contents of those templates is an unknown. you would need to tell the tool what you want in there. If it's just a repetition of the input, then use a parse tree (not an AST) or my TokenRewriteStream.

My goal is to start with an antlr grammar specifying a certain language,  and generate a lexer+parser that produces an AST from a concrete programme.  I also want to be able to „unparse“ the AST to obtain the exact (or corresponding) code that (would) produce(d) it (possibly after changing the AST).

Demanding a set of StringTemplates as well seems redundant in this case, as the source and destination languages are exactly the same (this might seem strange but makes sense in our context J )!
