Equis

A programming language that understands REA accounting

What it does

Equis is a compiled systems language that embeds REA (Resource-Event-Agent) accounting semantics directly into its compiler. Declare agents, resources, and events as language primitives. The compiler verifies balanced transactions, role-based access, and contract fulfillment before your code can run. Self-hosted compiler, LLVM backend, cross-platform (Linux/macOS/Windows), with a standard library that includes fixed-point math, JSON, PostgreSQL bindings, and cooperative concurrency.

    Numscript is a simple, declarative language that helps you model financial transactions. You can do quite a few things with it, such as modeling: * Payments involving vouchers and a user's prepaid balance * Complex funds destination scenario where the customer gets cash back * Configurable user credit balance spending transactions The main idea is to take the pain out of describing of a system dealing with money movements should behave in traditional languages such as JS/TS/Go/Ruby etc, landing an expressive way to model these movements of value.
