- Added 'peak.metamodels.ASDL', a metamodel for the Zephyr Abstract Syntax |
| |
Description Language. ASDL is a convenient way to describe a domain model |
| |
for an abstract syntax tree (AST), and the models generated with the new |
| |
ASDL tool can be combined with concrete syntax to create a complete parsing |
| |
solution for "mini languages", possibly including the Python language |
| |
itself. (Future versions of the Python and Jython compilers are likely to |
| |
use AST models based on ASDL, and in the current Python CVS sandbox there's |
| |
already an ASDL model of Python's AST available.) |

- Enhanced 'fmtparse' and 'peak.model' to allow using types as syntax rules |
