Add ast.Constant

2016-01-25T23:40:57+00:00

Issue #26146: Add a new kind of AST node: ast.Constant. It can be used by
external AST optimizers, but the compiler does not emit directly such node.

An optimizer can replace the following AST nodes with ast.Constant:

* ast.NameConstant: None, False, True
* ast.Num: int, float, complex
* ast.Str: str
* ast.Bytes: bytes
* ast.Tuple if items are constants too: tuple
* frozenset

Update code to accept ast.Constant instead of ast.Num and/or ast.Str:

* compiler
* docstrings
* ast.literal_eval()
* Tools/parser/unparse.py

Issue #22823: Use set literals instead of creating a set from a list

Fix bootstrapping asdl -- it didn't work with Python 2.7.

Issue #19655: Replace the ASDL parser carried with CPython

2014-05-10T00:58:22+00:00

The new parser does not rely on Spark (which is now removed from our repo),
uses modern 3.x idioms and is significantly smaller and simpler.

It generates exactly the same AST files (.h and .c), so in practice no builds
should be affected.

Move open outside try/finally

Don't use fancy new Python features like 'with' - some bots don't have them

and can't bootstrap the parser.

Normalize whitespace

Small fixes in Parser/asdl.py - no change in functionality.

2013-09-26T13:31:32+00:00

1. Make it work when invoked directly from the command-line. It was failing
   due to a couple of stale function/class usages in the __main__ section.
2. Close the parsed file in the parse() function after opening it.

unify some ast.argument's attrs; change Attribute column offset (closes #16795)
