This is the main source code repository for the Jac programming language. It contains the compiler, language server, and documentation.

What and Why Jac?

• Native Superset of Python - Jac is a native superset of python, meaning the entire python ecosystem is directly interoperable with Jac without any trickery (no interop interface needed). Like Typescript is to Javascript, or C++ is to C, Jac is to Python. (every Jac program can be ejected to pure python, and every python program can be transpiled to a Jac program)

• AI as a Programming Language Constructs - Jac includes a novel (neurosymbolic) language construct that allows replacing code with generative AI models themselves. Jac's philosophy abstracts away prompt engineering. (Imagine taking a function body and swapping it out with a model.)

• New Modern Abstractions - Jac introduces a paradigm that reasons about persistence and the notion of users as a language level construct. This enables writing simple programs for which no code changes are needed whether they run in a simple command terminal, or distributed across a large cloud. Jac's philosophy abstracts away dev ops and container/cloud configuration.

• Jac Improves on Python - Jac makes multiple thoughtful quality-of-life improvements/additions to Python. These include new modern operators, new types of comprehensions, new ways of organizing modules (i.e., separating implementations from declarations), etc.

Quick Start

To install Jac, run:

pip install jaclang
