ANN compiler2：从Python 2.5抽象语法树生成字节码 [英] ANN compiler2 : Produce bytecode from Python 2.5 Abstract Syntax Trees

问题描述

宣布：编译器2

---------------------


对于所有字节码爱好者：''compiler2''是标准

库''编译''包的替代品，具有几个优点。


改进的纯python编译器


- 为所有/ Lib

和Lib / test模块的内置编译函数生成相同的字节码* ，包括''窥视孔''优化

- 使用2.5'''工厂安装''ASTs，而不是2.4'''''售后''

版本

- 明显更快


*除了讨厌的堆栈深度计算


可能应用程序


- 理解/记录/验证编译过程

- 实现实验编译功能（编译时常量，

函数插入任何人？）

- 无论旧的编译器pac kage用于;-)

入门

---------------

指向你的svn客户：
http://svn.brownspencer.com /pycompil...nches/new_ast/

查看PYTHONPATH上的compiler2目录

使用python test / test_compiler.py进行测试

干杯

Announcing: compiler2
---------------------

For all you bytecode enthusiasts: ''compiler2'' is an alternative to the standard
library ''compiler'' package, with several advantages.

Improved pure-python compiler

- Produces identical bytecode* to the built-in compile function for all /Lib
and Lib/test modules, including ''peephole'' optimizations
- Works with 2.5''s ''factory-installed'' ASTs, rather than 2.4''s ''after-market''
version
- Is significantly faster

* Except for the pesky stack-depth calculation

Possible applications

- Understanding/documenting/verifying the compilation process
- Implementing experimental compilation features (compile-time constants,
function in-lining anyone?)
- Whatever the old compiler package is used for ;-)
Getting started
---------------
Point your svn client to:
http://svn.brownspencer.com/pycompil...nches/new_ast/

Check out to a compiler2 directory on PYTHONPATH
Test with python test/test_compiler.py
Cheers
Michael

这是从头开始重写还是改进的stdlib编译器包？


在后一种情况下，也许你可以为核心贡献一些补丁。


Georg

Is this a rewrite from scratch, or an improved stdlib compiler package?

In the latter case, maybe you can contribute some patches to the core.

It开始作为后者（即stdlib编译器包改进）和

通过增量更改进行，其目标是生成正确的
目标代码并创建一个干净的编译器体系结构（后者有点

主观当然）。原则上我会很高兴为这项工作做出贡献，但是这些变化的总和相当于一次重大的重写，所以我不认为它是好的。
可以作为补丁有意义地提交。

It started as the latter (i.e., the stdlib compiler package improved) and
proceeded via incremental change with the twin goals of generating correct
object code and creating a clean compiler architecture (the latter somewhat
subjective of course). I''d be happy in principle to contribute the work, but
the sum of the changes amounts to a substantial re-write, so I don''t think it
can be meaningfully submitted as a patch.

也许你可以就python-dev讨论你的改进

以及如何将它们集成到标准库中。 。


Georg

Perhaps you can bring up a discussion on python-dev about your improvements
and how they could be integrated into the standard library...
