Implement other Language version of LangChain

[ken20220214]

Issue you'd like to raise.

LangChain framework mostly aims to build applications which interact with LLM. Many online applications themselves are implements by other languages such as Java,C++, but LangChain only supports Python and JS by now. How about implement other language version of LangChain?

I think this is a great suggestion and would be nice to see this feature. I love the idea of adding support for Java and C# too.

Yes, but actually, it's a big project I think. It may take some time.

In Java, you can use LangChain: https://github.com/HamaWhiteGG/langchain-java @ken20220214 @izzymsft @Undertone0809

A great project! But I want to know how many features have been revived? Moreover, I don't seem to have seen the documentation of it.

Yes, we truly need a C++ version for project.

Hi, @ken20220214,

I'm helping the LangChain team manage their backlog and am marking this issue as stale. From what I understand, the issue you raised proposes adding support for languages like Java and C++ to LangChain, which currently only supports Python and JS. There was some interest and discussion around the idea, with existing Java implementations being shared, and concerns raised about the features and documentation of those implementations.

Could you please confirm if this issue is still relevant to the latest version of the LangChain repository? If it is, please let the LangChain team know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you!

So how do I use LangChain from a C++ program?
