How to write a shell in Python
提问by panzi
I've written a small console application that can perform certain tasks. The user interface is similar to things like version control systems or yum etc. So basically you can think of it as a domain specific language. Now I'd like to write a (bash like) shell that can execute and auto-complete this language and has a command history (so I do not have to load and save the quite large xml files on each command). In a nutshell I want something like ipython but not for executing python code but my own DSL.
我编写了一个可以执行某些任务的小型控制台应用程序。用户界面类似于版本控制系统或 yum 等。所以基本上你可以将其视为特定领域的语言。现在我想编写一个（类似 bash 的）shell，它可以执行和自动完成这种语言并具有命令历史记录（因此我不必在每个命令上加载和保存相当大的 xml 文件）。简而言之，我想要像 ipython 这样的东西，但不是为了执行 python 代码，而是我自己的 DSL。
Are there any libraries that help me doing this? I see that there is a readline and rlcompleter module in python but its documentation seems to indicate that this is only for use with the python shell itself, or did I miss something there?
是否有任何图书馆可以帮助我做到这一点？我看到 python 中有一个 readline 和 rlcompleter 模块，但它的文档似乎表明这仅适用于 python shell 本身，或者我错过了什么？

If you need an administrative shell to be accessed via network Twistedpython framework's manhole is a good solution. Example:
如果您需要通过网络访问管理 shell，Twistedpython 框架的检修孔是一个很好的解决方案。例子：
