How to convert ActionSequence/AST to CODE?

[LiuZeJie97]

First, I would like to thank you for the publication of the source code.

In order to calculate the BLEU score, I need to convert ActionSequence/AST to plain text, however, I didn't find any related functions/code snippet in the code you provided.

在计算BLEU时，我需要将模型输出的动作序列/抽象语法树转化为代码，但是我在您提供的代码中没有找到实现该功能的函数/代码片段，非常感谢！
