* bpo-31241: Fix AST node position for list and generator comprehensions. ↵Serhiy Storchaka2018-11-271-11/+40
| | | | | | | | (GH-10633) The lineno and col_offset attributes of AST nodes for list comprehensions, generator expressions and tuples are now point to the opening parenthesis or square brace. For tuples without parenthesis they point to the position of the first item.
* bpo-34876: Change the lineno of the AST for decorated function and class. ↵Serhiy Storchaka2018-10-301-2/+14
| | | | | | | (GH-9731) It was overridden by the lineno of the first decorator. Now it is the lineno of 'def' or 'class'.
* bpo-32892: Support subclasses of base types in isinstance checks for AST ↵Serhiy Storchaka2018-10-281-0/+4
| | | | | | | constants. (GH-9934) Some projects (e.g. Chameleon) create ast.Str containing an instance of the str subclass.
* bpo-32892: Use ast.Constant instead of specific constant AST types. (GH-9445)Serhiy Storchaka2018-09-271-53/+151

* closes bpo-31902: Fix the col_offset attribute for ast.Async* nodes to point ↵guoci2018-09-111-4/+4

* bpo-29622: Make AST constructor to accept less than enough number of ↵INADA Naoki2017-02-231-4/+0
| | | | | | | | | | | positional arguments (GH-249) bpo-29463 added optional "docstring" field to 4 AST types. While it is optional, it breaks backward compatibility because AST constructor requires number of positional argument is same to number of fields. AST types accepts empty arguments, and incomplete keyword arguments. But it's not big problem because field can be filled after creation, and checked when compiling. So stop requiring complete set of fields for positional arguments too.
* bpo-29463: Add docstring field to some AST nodes. (#46)INADA Naoki2017-02-221-73/+87
| | | | | | | | | | | * bpo-29463: Add docstring field to some AST nodes. ClassDef, ModuleDef, FunctionDef, and AsyncFunctionDef has docstring field for now. It was first statement of there body. * fix document. thanks travis! * doc fixes

* compiler: don't emit SyntaxWarning on const stmtVictor Stinner2016-02-081-5/+2
| | | | | Issue #26204: the compiler doesn't emit SyntaxWarning warnings anymore when constant statements are ignored.
* compiler now ignores constant statementsVictor Stinner2016-02-081-17/+16
| | | | | | | | | | | | | | | | | | | The compile ignores constant statements and emit a SyntaxWarning warning. Don't emit the warning for string statement because triple quoted string is a common syntax for multiline comments. Don't emit the warning on ellipis neither: 'def f(): ...' is a legit syntax for abstract functions. Changes: * test_ast: ignore SyntaxWarning when compiling test statements. Modify test_load_const() to use assignment expressions rather than constant expression. * test_code: add more kinds of constant statements, ignore SyntaxWarning when testing that the compiler removes constant statements. * test_grammar: ignore SyntaxWarning on the statement "1"
* Simplify main() of test_astVictor Stinner2016-02-081-2/+3

* Add ast.ConstantVictor Stinner2016-01-251-1/+119
| | | | | | | | | | | | | | | | | | | | | 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
