a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	10 The tests are all raise SyntaxErrors. They were created by checking
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	11 each C call that raises SyntaxError. There are several modules that
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	12 raise these exceptions-- ast.c, compile.c, future.c, pythonrun.c, and

a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	15 The parser itself outlaws a lot of invalid syntax. None of these
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	16 errors are tested here at the moment. We should add some tests; since
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	17 there are infinitely many programs with invalid syntax, we would need
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	18 to be judicious in selecting some.

a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	20 The compiler generates a synthetic module name for code executed by
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	21 doctest. Since all the code comes from the same module, a suffix like
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	22 [1] is appended to the module name, As a consequence, changing the
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	23 order of tests in this module means renumbering all the errors after
a625e8876407 Improved handling of syntax errors. Jeremy Hylton <jeremy@alum.mit.edu> parents: 35959 diff changeset	24 it. (Maybe we should enable the ellipsis option for these tests.)
