Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Please add module support for bz2.
Currently Not covenient to read data from compressed files.

it looks like it should be possible, but I'm not sure how generally useful 
support
for bz2 would be.. :-) do you have a use case where you really need this..?

Yes, that's why I bring this up. :) There are some data mining/analysis 
programs in 
my tool chain which handle huge data files (GBs) and most of them are 
compressed by 
bz2. 
Please consider it when possible

FYI
bzip lib: http://www.bzip.org/
bz2 module wrapper can be found in python source code

Thanks
Jason

BTW, Is it possible to use modules in Shedskin through PythonVM ? So we don't 
need 
to translate non-performance critical or binary modules into c++. Flexibility 
will 
be greatly improved.
I know the iteroperability between c/c++ and python is good, but no experience 
in 
thare area

Extension Module for details)

hehe, I mean if I used un-supported modules in code, possible to use Python VM 
to 
execute that module while my code are tranlated into c++?
For example: when I use bz2 module in a program, can we let cpython to execute 
bz2, 
and all other pure python code tranlated into c++.

sorry I forgot to answer this. I don't think this will ever be possible, 
because of type inference constraints..

I moved all standard library related issues into issue 106.
