Shed Skin 0.1 (Default branch)

Shed Skin is an experimental (restricted-)Python-to-C++ compiler. It accepts pure but implicitly statically typed Python programs and generates optimized C++ code. The result can be further compiled to stand-alone programs or extension modules. For a set of 16 non-trivial test programs, measurements show a typical speedup of 2-40 over Psyco, about 10 on average, and 2-220 over CPython, about 35 on average. Not all Python features are supported, and only a subset of about 17 library modules, such as re and random. License: GNU General Public License v3 Changes:
Improved support for 'os' (UNIX). The addition of a JPEG decoder (1200 lines) and some other programs to the set of example programs. Extension module fixes. Improved compiler flags under OS X. An important type inference fix. Improved variable overloading. Casting improvements. Fixes for setslice and delslice corner cases. xrange returns an xrange object, not iterator. There are several minor bugfixes.

Cant set default skin

Neo, I have tried numerous times to set my skin to the Matrix clone but it never sticks... I tried various other ones but it keeps going back to that classic baby blue...with the UNIX in the middle of a cloud. Tell me what is going on. I know Im not going crazy... b/c I already am. :p :D

Skin for PDA

Let me know if you find a skin or template for vB 2.x that can be used for mobile users (PDAs, etc.). I think we need a small mobile device skin for the forums What do you think?

Can anyone shed some light on this HACMP failover?

Hello All, Here is a snipet from our cluster.log, I was wondering if anyone could shed some light on what may have caused the failover. The first two lines indicate a possible memory issue which I am currently looking into. Thanks.

NAME

       Shedskin - An experimental (restricted) Python-to-C++ Compiler

SYNOPSIS

       shedskin [OPTION]... FILE

DESCRIPTION

       Shed  Skin  is  an experimental compiler, that can translate pure, but implicitly statically typed Python (2.4-2.6) programs into optimized
       C++. It can generate stand-alone programs or extension modules that can be imported and used in larger Python programs.

       Besides the typing restriction, programs cannot freely use the Python standard library (although about 25 common modules,  such	as  random
       and re, are currently supported). Also, not all Python features, such as nested functions and variable numbers of arguments, are supported.

OPTIONS

	  -a --ann		 Output annotated source code (.ss.py)

	  -b --nobounds 	 Disable bounds checking

	  -e --extmod		 Generate extension module

	  -f --flags		 Provide alternate Makefile flags

	  -l --long		 Use long long integers

	  -m --makefile 	 Specify alternate Makefile name

	  -n --silent		 Silent mode, only show warnings

	  -o --noassert 	 Disable assert statements

	  -r --random		 Use fast random number generator (rand())

	  -s --strhash		 Use fast string hashing algorithm (murmur)

	  -w --nowrap		 Disable wrap-around checking

	  -x --traceback	 Print traceback for uncaught exceptions

	  -L --lib		 Add a library directory
