kambo-1st / langchain-php Goto Github PK

What happened?

Hellow @kambo-1st, I wanted to inquire on the possibility of contributing some new functionalities to the package.

Recently, I've released a PHP package that integrates ChromaDB within PHP applications. I'm keen on extending this support to the package and additionally adding compatibility for other vector stores like Pinecone, Milvus, among others, to broaden the options available for users.

Before diving into the implementation, I wanted to inquire about the current activity and maintenance status of repo. Are new contributions welcomed? Is any active development still going on?

What happened?

When trying to use this port of Langchain for PHP I find that the main file Langchain.php is not located in the root of the namespace /src.

Only one version is present in /src/Exceptions, which causes errors when trying to load the class.

Please consider moving the file to the expected location in /src/Langchain.php so that the library can be used properly.

Also validate that the version in Exceptions is complete and correct for general use.

Thank you for your work on this unofficial port. It would be very useful to have a stable and well-implemented version of Langchain for PHP.

Best regards

I want to discuss creating a vectorstore with this -> https://github.com/pgvector/pgvector-php.
It's a postgresql extension which allows you to query vectors which makes it a pretty good candidate for many php users.

Final classes make it harder for developers to extend package functionality in their own projects. What's the benefit that you see?
