"""This module tests SyntaxErrors.

Here's an example of the sort of thing that is tested.

>>> def f(x):
...     global x
Traceback (most recent call last):
SyntaxError: name 'x' is parameter and global

The tests are all raise SyntaxErrors.  They were created by checking
each C call that raises SyntaxError.  There are several modules that
raise these exceptions-- ast.c, compile.c, future.c, pythonrun.c, and
symtable.c.

The parser itself outlaws a lot of invalid syntax.  None of these
errors are tested here at the moment.  We should add some tests; since
there are infinitely many programs with invalid syntax, we would need
to be judicious in selecting some.

The compiler generates a synthetic module name for code executed by
doctest.  Since all the code comes from the same module, a suffix like
[1] is appended to the module name, As a consequence, changing the
order of tests in this module means renumbering all the errors after
it.  (Maybe we should enable the ellipsis option for these tests.)

In ast.c, syntax errors are raised by calling ast_error().

Errors from set_context():

If the left-hand side of an assignment is a list or tuple, an illegal
expression inside that contain should still cause a syntax error.
This test just checks a couple of cases rather than enumerating all of
them.

>>> (a, "b", c) = (1, 2, 3)
Traceback (most recent call last):
SyntaxError: cannot assign to literal

>>> (a, True, c) = (1, 2, 3)
Traceback (most recent call last):
SyntaxError: cannot assign to True

>>> (a, __debug__, c) = (1, 2, 3)
Traceback (most recent call last):
SyntaxError: cannot assign to __debug__

>>> (a, *True, c) = (1, 2, 3)
Traceback (most recent call last):
SyntaxError: cannot assign to True

>>> (a, *__debug__, c) = (1, 2, 3)
Traceback (most recent call last):
SyntaxError: cannot assign to __debug__

>>> [a, b, c + 1] = [1, 2, 3]
Traceback (most recent call last):
SyntaxError: cannot assign to expression

SyntaxError: cannot assign to expression

Traceback (most recent call last):
SyntaxError: cannot assign to expression

>>> a if 1 else b = 1
Traceback (most recent call last):
SyntaxError: cannot assign to conditional expression

>>> a = 42 if True
Traceback (most recent call last):
SyntaxError: expected 'else' after 'if' expression

>>> a = (42 if True)
Traceback (most recent call last):
SyntaxError: expected 'else' after 'if' expression

>>> a = [1, 42 if True, 4]
Traceback (most recent call last):
SyntaxError: expected 'else' after 'if' expression

>>> if True:

>>> True = True = 3
Traceback (most recent call last):
SyntaxError: cannot assign to True

>>> x = y = True = z = 3
Traceback (most recent call last):
SyntaxError: cannot assign to True

Traceback (most recent call last):
SyntaxError: assignment to yield expression not possible

>>> a, b += 1, 2
Traceback (most recent call last):
SyntaxError: 'tuple' is an illegal expression for augmented assignment

>>> (a, b) += 1, 2
Traceback (most recent call last):
SyntaxError: 'tuple' is an illegal expression for augmented assignment

>>> [a, b] += 1, 2
Traceback (most recent call last):

Invalid targets in `for` loops and `with` statements should also
produce a specialized error message

>>> for a() in b: pass
Traceback (most recent call last):
SyntaxError: cannot assign to function call

Traceback (most recent call last):
SyntaxError: cannot assign to function call

Traceback (most recent call last):
SyntaxError: cannot assign to function call

>>> for (*a, b, c+1) in b: pass
Traceback (most recent call last):
SyntaxError: cannot assign to expression

>>> for (x, *(y, z.d())) in b: pass
Traceback (most recent call last):
SyntaxError: cannot assign to function call

>>> for a, b() in c: pass
Traceback (most recent call last):
SyntaxError: cannot assign to function call

>>> for a, b, (c + 1, d()): pass
Traceback (most recent call last):
SyntaxError: cannot assign to expression

Traceback (most recent call last):
SyntaxError: cannot assign to function call

>>> with a as b
Traceback (most recent call last):
SyntaxError: expected ':'

>>> p = p =
Traceback (most recent call last):
SyntaxError: invalid syntax

Comprehensions creating tuples without parentheses
should produce a specialized error message:

>>> [x,y for x,y in range(100)]
Traceback (most recent call last):
SyntaxError: did you forget parentheses around the comprehension target?

>>> {x,y for x,y in range(100)}
Traceback (most recent call last):
SyntaxError: did you forget parentheses around the comprehension target?

# Missing commas in literals collections should not
# produce special error messages regarding missing
# parentheses, but about missing commas instead

>>> [1, 2 3]
Traceback (most recent call last):
SyntaxError: invalid syntax. Perhaps you forgot a comma?

>>> {1, 2 3}
Traceback (most recent call last):
SyntaxError: invalid syntax. Perhaps you forgot a comma?

>>> {1:2, 2:5 3:12}
Traceback (most recent call last):
SyntaxError: invalid syntax. Perhaps you forgot a comma?

>>> (1, 2 3)
Traceback (most recent call last):
SyntaxError: invalid syntax. Perhaps you forgot a comma?

# Make sure soft keywords constructs don't raise specialized
# errors regarding missing commas or other spezialiced errors

    SyntaxError: 'continue' not properly in loop

There is one test for a break that is not in a loop.  The compiler
uses a single data structure to keep track of try-finally and loops,
so we need to be sure that a break is actually inside a loop.  If it
isn't, there should be a syntax error.

>>> try:
   ...     print(1)
   ...     break
   ...     print(2)
   ... finally:

   Traceback (most recent call last):
