NexaCore
NexaCore is a new compiled programming language for backend systems, APIs, databases, and long-running services.
This repository contains:
- the language design foundation
- the compiler workspace
- the runtime and standard library layout
- starter examples for backend-oriented development
The first MVP compiler path compiles NexaCore source into a typed intermediate representation and then emits C as the initial backend target. That keeps the compiler realistic to build now while preserving a clean path toward a later native backend.
See docs/nexacore-foundation.md for the architectural design and MVP roadmap.
