Python本身实现了另一种脚本语言？ [英] Another scripting language implemented into Python itself?
问题描述
我有兴趣开发一个应用程序，其中用户有足够的电量来定制应用程序以满足他们的需求，并且
我觉得这最好是如果脚本语言可用，则可以完成。但是，我想用Python编写这个应用程序，而且我还没有听说过在Python中使用另一种脚本语言
的实现。
我的意思是这个（Lua到Ruby的实现
- 我不想使用它）： http://ruby-lua.unolotiene.com/
我知道C / C ++可能更适合这种任务，但是我的应用程序中需要速度的模块中的大多数已经用C ++编码了
。我想用Python作为胶水。对于这个项目;
使用漂亮的GUI编写整个应用程序并不好玩，因为大多数
你可能从以前的经验中知道。
所以，我的问题很简单：Python中是否有另一种
脚本语言的实现？

Python *是一种脚本语言。为什么不让你的用户写一下？b $ b Python模块你通过一些定义的API导入和执行它们？

因为你不能使Python对恶意安全（或者
无知）用户 - 对于用户代码可能损害系统的每种可能方式，能够保护
的灵活性太大。 />
解析你自己的（有限的）脚本语言可以更好地控制用户代码能够做什么，因此允许
（至少对恶意代码的安全措施。
对于OP：是的，人们用Python实现了其他语言。
例如，我相信Danny Yoo用Python写了一个Scheme
口译员（Google告诉我它应该在
http://hkn.eecs.berkeley.edu/~dyoo/python/pyscheme 但我没有得到
来自该主机的响应），但我不知道Scheme
是否算作脚本语言。 ;）
但是，如果您为这些用户使用功能齐全的语言
脚本，您可能会遇到相同的安全问题我提到了
Python。除非你真的需要这种级别的功能，否则你可以更好地设计自己的有限语言。检查文件
for pyparsing for a starter ...

这也是我的想法，注意到您只需要将用户需要的文件记录为
，包括要导入的特定模块（如果有的话）。

I am interested in developing an application where the user has an
ample amount of power to customize the application to their needs, and
I feel this would best be accomplished if a scripting language was
available. However, I want to code this application in Python, and I
have not yet heard of an implementation of another scripting language
into Python.
An example of what I mean is this (an implementation of Lua into Ruby
-- which I''d prefer not to use): http://ruby-lua.unolotiene.com/
I know C/C++ might be better suited for a task of this kind, but most
of the modules in my application which need speed have already been
coded in C++. I want to use Python as the "glue" for this project;
writing an entire application with a pretty GUI is not fun, as most of
you may know from previous experience.
So, my question is simply this: is there an implementation of another
scripting language into Python?

Python *is* a scripting language. Why not just let your users write
Python modules which you them import and execute via some defined API?

Because you cannot make Python secure against a malicious (or
ignorant) user -- there''s too much flexibility to be able to guard
against every possible way in which user-code could harm the system.
Parsing your own (limited) scripting language allows much better
control over what user-code is capable of doing, and therefore allows
(at least some measure of) security against malicious code.
To the O.P.: Yes, people have implemented other languages in Python.
For example, I believe that Danny Yoo has written a Scheme
interpreter in Python (Google tells me it should be at
http://hkn.eecs.berkeley.edu/~dyoo/python/pyscheme but I''m getting no
response from that host right now), but I don''t know whether Scheme
counts as a scripting language. ;)
However, if you''re using a fully-featured language for these user
scripts, you''ll probably have the same security issues I mentioned for
Python. Unless you really need that level of features, you may be
better off designing your own limited language. Check into the docs
for pyparsing for a starter...

That was my thought also, with the note that you only need to document as
much users will need, including specific modules (if any) to import.
