* bpo-44180: Fix edge cases in invalid assigment rules in the parser (GH-26283)Pablo Galindo2021-05-21
| | | | | | | | | | | | | | | The invalid assignment rules are very delicate since the parser can easily raise an invalid assignment when a keyword argument is provided. As they are very deep into the grammar tree, is very difficult to specify in which contexts these rules can be used and in which don't. For that, we need to use a different version of the rule that doesn't do error checking in those situations where we don't want the rule to raise (keyword arguments and generator expressions). We also need to check if we are in left-recursive rule, as those can try to eagerly advance the parser even if the parse will fail at the end of the expression. Failing to do this allows the parser to start parsing a call as a tuple and incorrectly identify a keyword argument as an invalid assignment, before it realizes that it was not a tuple after all.

* bpo-43914: Highlight invalid ranges in SyntaxErrors (#25525)Pablo Galindo2021-04-23
| | | | | | | | | | | | | | | | | To improve the user experience understanding what part of the error messages associated with SyntaxErrors is wrong, we can highlight the whole error range and not only place the caret at the first character. In this way: >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^ SyntaxError: Generator expression must be parenthesized becomes >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^^^^^^^^^^^^^^^^^^^^ SyntaxError: Generator expression must be parenthesized
