The first release candidate for the Expert language server project is now available!

Welcome to the 18th International Symposium on Functional and Logic

A first-principles guide to process-based concurrency — what makes BEAM different, how OTP encodes resilience into architecture, and why everyone keeps reinventing it.

Easy to use bindings to the Gemini API. These functions and structs follow the API very closely, making it very easy to follow their usage from the API docs.

The docs can be found at https://hexdocs.pm/geminix.
