IronPython compile()不接受AST对象 [英] IronPython compile() does not accept AST object

问题描述

在说明文件中，源"可以是str或AST对象

In the documentation it says, 'source' can be either str or AST object

当尝试编译我的ast根时:

When trying to compile my ast root:

dl = compile(newRoot, '<string>', 'eval')

我收到此异常:

expected str, got Module

我正在使用IronPython的最新版本.

I am using the last version of IronPython.

有没有一个想法为什么不起作用?我发现的所有示例似乎都是以这种方式完成的.

Is there an idea why this does not work? all the examples I found seem to do it this way with no issues.

是否有解决方法来编译AST对象?

Is there a workaround to compile an AST object?

谢谢!!!!

推荐答案

首先，IronPython不支持此功能.

First off, IronPython does not support this.

实际上很难在IronPython中支持(直到今天我才知道它需要得到支持). IronPython的_ast模块是其自身AST的包装，并且当前仅实现从IronPython AST => CPython AST的转换，但不是反向转换.这是一件相当(诚实，非常乏味)的工作，所以我不确定什么时候可以解决.

It's actually quite hard to support in IronPython (and I didn't know it needed to be supported until today). IronPython's _ast module is a wrapper around its own AST, and currently only implements conversion from IronPython AST => CPython AST, but not the reverse. It's a fair bit of (honestly, quite tedious) work, so I'm not sure when it will get fixed.

如果有一个流行的程序或库因此而被破坏，从而将其移到优先级列表中，那么总是欢迎使用补丁程序.

If there's a popular program or library that's broken because of this that moves it up the priority list, and patches are always welcome.
