用python编写DSL的编译器 [英] Writing a compiler for a DSL in python

问题描述

我正在用python编写游戏，因此决定为地图数据文件创建DSL.我知道我可以用regex编写自己的解析器，但是我想知道是否有现有的python工具可以更轻松地完成此操作，例如PHP引擎中使用的re2c.

I am writing a game in python and have decided to create a DSL for the map data files. I know I could write my own parser with regex, but I am wondering if there are existing python tools which can do this more easily, like re2c which is used in the PHP engine.

一些额外的信息:

• 是的，我需要，但即使我不想要DSL，我仍然想要在项目中构建和使用一个DSL的经验.

• DSL仅包含数据(声明式?)，不会执行".大多数行看起来像:

• Yes, I do need a DSL, and even if I didn't I still want the experience of building and using one in a project.

• The DSL contains only data (declarative?), it doesn't get "executed". Most lines look like:

SOMETHING: !abc @123 #xyz/123

我只需要读取数据树即可.

I just need to read the tree of data.
