大家一起玩 PYPY
2010 年长三角地区 PYTHON 11 月聚会
使用 PYTHON 解析 PYTHON
起先有了 PSYCO
JIT
PYTHON 版本
CPU
更快更智能的 JIT
更快?编译执行!
http://code.google.com/p/shedskin/
于是就有了 RPYTHON
编译期优化
BACKEND
C .NET JAVA
PROLOG SMALLTALK
JAVASCRIPT IO SCHEME GAMEBOY
ctypes lltypesystem
MixedModule
PYPY 1.1
像 C 一样快的动态语言
不需要 MixedModule
重新实现 PYTHON 解释器
使用 RPYTHON 编写
即使你不了解 C 也没关系
RPYTHON CAN BE FAST THAN C
指令越高端,优化空间就越大
解释器
编写越便利, JIT 越强大
无须编译即可调试
支持巨量平台
STACKLESS PYTHON
不只是 PYTHON
UNLADEN SWALLOW
突然出现
LLVM
RPYTHON → LLVM
PYPY 1.2
JIT
PYPY 1.3
CPYEXT
PYPY 1.4 已于 26 号发布
http://pypy.org
http://morepypy.blogspot.com
自编译!
