Indeed, that error is a bit confusing and a help switch would be most
helpful (no pun intended). However, tinypy doesn't support any command
line options at this time. A few switches that would be nice come to
mind, like an option to input code inline/from stdin, or one for
compiling directly to bytecode (running ./build/tinypy

ok - thanks the paranthesis solved the problem when running the
script. I have output now.
But what's with the error when running the just the interepreter

Is this an error or standard behavior?
If yes - wouldn't it be nice to have the same behavior as with a

Hello Ben,
tinypy behaves like Python 3.0 in this regard and treats print as a
function. If you add parenthesis around the string, it should work.

hi
When I call the tinypy interpreter I get the following error:
$ ./build/tinypy
Exception:
tp_get: KeyError: 0
I've build tinypy on my ubuntu box and I think the compilation went fine:
$ python setup.py linux
# 83998 66995 1459
cd /usr/local/src/tinypy-1.1/tiny py

I've fixed the above mentioned issues so I think it's safe to close this

Also, I've changed the memory limit to use an unsigned long value, but the

Can someone take a look at, and commit any of Rene's patches that fix bugs in tinypy?

Also, let's see some of those issues get closed out in the issues list at google code. All the medium level issues should be closed, or at least pretty much resolved so we can release :)

Thanks!

New issue report by renesd:
hi,
vsprintf doesn't check the length of the string, whereas vsnprintf does.
So it's better to use vsnprintf instead, to avoid buffer overruns.

hi there,

here's some notes about the chrome OS level sandboxing that it uses on
windows.

Probably a useful place to research OS level sandboxing for tinypy on
windows.

hi,

as part of doing cpython.tinypy tests, I have made the
cpython_tests.py load the tinypy tests and run them. This way we can
see if they all run correctly in the cpython environment.

However, to make them more useful it would be good if the tests were
separated into 'units'. This could be done with comment markers, they
