The cause seems to be that when a file URL doesn't exist,
urllib.urlopen() raises OSError instead of IOError. Simply add this
to the except clause. Not elegant, but effective. :-)
(With slight cosmetic improvements to shorten lines and a grammar fix
to a docstring.)
This addes -X and -E options to freeze. From the docstring:
-X module Like -x, except the module can never be imported by
the frozen binary.
-E: Freeze will fail if any modules can't be found (that
were not excluded using -x or -X).
The strerror attribute contained only partial information about the
exception and produced some very confusing error messages. By passing
err (the exception object itself) and letting it convert itself to a
string, the error messages are better.
compile() becomes replacement for builtin compile()
compileFile() generates a .pyc from a .py
both are exported in __init__
compiler.parse() gets optional second argument to specify compilation
mode, e.g. single, eval, exec
Add AbstractCompileMode as parent class and Module, Expression, and
Interactive as concrete subclasses. Each corresponds to a compilation
mode.
THe AbstractCompileMode instances in turn delegate to CodeGeneration
subclasses specialized for their particular functions --
ModuleCodeGenerator, ExpressionCodeGeneration,
InteractiveCodeGenerator.
The argument properties are ordered from easiest to hardest. The
harder the arg, the more complicated that code that must be generated
to return it from getChildren() and/or getChildNodes(). The old
calculation routine was bogus, because it always set hardest_arg to
the hardness of the last argument. Now use max() to always set it to
the hardness of the hardest argument.
Remove the only test in the syntax module. It ends up that the
transformer must handle this error case.
In the transformer, check for a list compression in com_assign_list()
by looking for a list_for node where a comma is expected.
In pycodegen.compile() re-raise the SyntaxError rather than catching
it and exiting
Invoke compiler.syntax.check() after building AST. If a SyntaxError
occurs, print the error and exit without generating a .pyc file.
Refactor code to use compiler.misc.set_filename() rather than passing
filename argument around to each CodeGenerator instance.
introspection incompatibility, but in fact it's just that calltips
always gave up on a docstring that started with a newline (but
didn't realize they were giving up <wink>).
Remove the option to have nested scopes or old LGB scopes. This has a
large impact on the code base, by removing the need for two variants
of each CodeGenerator.
Add a get_module() method to CodeGenerator objects, used to get the
future features for the current module.
Set CO_GENERATOR, CO_GENERATOR_ALLOWED, and CO_FUTURE_DIVISION flags
as appropriate.
Attempt to fix the value of nlocals in newCodeObject(), assuming that
nlocals is 0 if CO_NEWLOCALS is not defined.
