Hiya. I am working hard on the code generator infrastructure for v4. I'm
extremely pleased with how the internals look and how easy it is to build the
templates for source code generation. Also, I'm very happy with how the lexer
bytecode interpreter has worked out. Here is the simple parser and lexer I ran
through the system:
parser grammar T;
options { tokenVocab = L; }
a : ID '=' expr ;
expr : INT ;
lexer grammar L;
ID : 'a'..'z'+ ;
INT : '0'..'9'+ ;
EQ : '=' ;
Just popping my head up as v4 hits milestones...
v4 runtime is almost exactly the same as v3 runtime. so far, the v4 grammar
syntax is identical as well (hurray!)
I still have a long way to go because ANTLR has so many little features and
lots of implementation details to worry about. I also need to work on an
academic paper this summer, which will delay me for a few months.
