Wechaty is All You Need: Python, Go, and Java Translation Project

[huan]

We already have Wechaty in TypeScript, It will be not too hard to translate the TypeScript(TS) to Python, Go, and Java languages because wechaty has only 3,000 lines of the TS code, they are well designed and de-coupled by the wechaty-puppet abstraction. So after we have translated those 3,000 lines of TypeScript code, we will almost be done.

As we have already an ecosystem of Wechaty in TypeScript, so we will not have to implement everything in other languages, especially, in Feb 2020, we have finished the @chatie/grpc service abstracting module with the wechaty-puppet-hostie implementation.

Architecture

The following diagram shows out that we can reuse almost everything in TypeScript, and what we need to do is only the block located at the top right of the diagram: Wechaty (Python).

Example: How to Translate TypeScript to Python

There's a 100 lines class named Image in charge of downloading the WeChat image to different sizes.

It is a great example for demonstrating how do we translate the TypeScript to Python in Wechaty Way:

Image Class Source Code

• TypeScript: https://github.com/wechaty/wechaty/blob/master/src/user/image.ts
• Python: https://github.com/wechaty/python-wechaty/blob/master/src/wechaty/user/image.py

If you are interested in the translation and want to look at how it works, it will be a good start from reading and comparing those two Image class files in TypeScript and Python at the same time.
