02:55 <abrown> quick question: I am trying to read an OS environment variable in RPython and `if 'DEBUG' in os.environ` is not allowed

02:56 <abrown> neither is `os.environ.get('DEBUG', False)`

02:56 <abrown> and I am trying to avoid a try-catch around it: does anyone know the RPython way to do this?

02:58 <simpson> Kind of surprised that the `in` version isn't allowed. The .get() wouldn't work because `False` isn't a string.

02:58 <simpson> `os.environ.items()` works, at least: https://github.com/monte-language/typhon/blob/master/typhon/objects/processes.py#L33

02:58 <simpson> There's a bunch of dict-like operations that should work.

02:58 <abrown> so you think os.environ.get('DEBUG', '0') would work? I can try that...

03:00 <abrown> nope

03:06 <abrown> thanks anyway

21:02 <catern> hey #pypy, question about cffi, I am extracting the libexecdir from a C library at "setup.py build" time and I want to store it somewhere so I can use it at run time, I was thinking of embedding the string into the cffi extension module as a const char *, how would I best format a Python string into my call to ffibuilder.set_source?
