* bpo-36917: Add default implementation of ast.NodeVisitor.visit_Constant(). ↵Serhiy Storchaka2019-08-261-0/+31
| | | | | | | (GH-15490) It emits a deprecation warning and calls corresponding method visit_Num(), visit_Str(), etc.
* bpo-35766: compile(): rename feature_version parameter (GH-13994)Victor Stinner2019-06-121-1/+1
| | | | | | Rename compile() feature_version parameter to _feature_version and convert it to a keyword-only parameter. Update also test_type_comments to pass feature_version as a tuple.
* bpo-35766: Change format for feature_version to (major, minor) (GH-13992)Guido van Rossum2019-06-111-1/+8
| | | | | | | (A single int is still allowed, but undocumented.) https://bugs.python.org/issue35766
* bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)Guido van Rossum2019-03-071-2/+4
| | | | | | | This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.) https://bugs.python.org/issue35975

* bpo-33416: Add end positions to Python AST (GH-11605)Ivan Levkivskyi2019-01-221-8/+92
| | | | | | | | | | | | | | | | | | The majority of this PR is tediously passing `end_lineno` and `end_col_offset` everywhere. Here are non-trivial points: * It is not possible to reconstruct end positions in AST "on the fly", some information is lost after an AST node is constructed, so we need two more attributes for every AST node `end_lineno` and `end_col_offset`. * I add end position information to both CST and AST. Although it may be technically possible to avoid adding end positions to CST, the code becomes more cumbersome and less efficient. * Since the end position is not known for non-leaf CST nodes while the next token is added, this requires a bit of extra care (see `_PyNode_FinalizeEndPos`). Unless I made some mistake, the algorithm should be linear. * For statements, I "trim" the end position of suites to not include the terminal newlines and dedent (this seems to be what people would expect), for example in ```python class C: pass pass ``` the end line and end column for the class definition is (2, 8). * For `end_col_offset` I use the common Python convention for indexing, for example for `pass` the `end_col_offset` is 4 (not 3), so that `[0:4]` gives one the source code that corresponds to the node. * I added a helper function `ast.get_source_segment()`, to get source text segment corresponding to a given AST node. It is also useful for testing. An (inevitable) downside of this PR is that AST now takes almost 25% more memory. I think however it is probably justified by the benefits.
