SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you add Prolog-style logic, unification, and backtracking to JavaScript or TypeScript projects when ordinary branching and filtering become hard to maintain.

Core Features & Use Cases

  • Declarative rule solving: Define facts and rules, then query them to find all matching solutions.
  • Pattern matching with extraction: Match nested JavaScript structures while binding out the values you need.
  • Constraint and search workflows: Model planning, authorization, dependency resolution, type inference, and expert-system style reasoning.
  • Multiple execution styles: Choose callback, generator, async callback, or async generator drivers depending on whether your logic is synchronous or awaits external work.

Quick Start

Use the use-yopl skill to add a small rule database, solve a query, and extract the bound results with the appropriate yopl driver.

FAQPage Schema
How do I add Prolog-style logic programming to a JavaScript or TypeScript project?

You can add Prolog-style logic programming to JavaScript using a solver that supports declarative rules, unification, and backtracking search. This allows you to query facts and rules to find all matching solutions within your application.

What is the best way to implement pattern matching and constraint solving in JavaScript?

The best way to implement pattern matching and constraint solving in JavaScript is using a declarative rule engine. It matches nested structures, binds out needed values, and handles planning, dependency resolution, and type inference.

Can I use a logic solver for asynchronous queries in TypeScript?

Yes, you can use a logic solver for asynchronous queries in TypeScript. You can choose between callback, generator, async callback, or async generator drivers depending on whether your logic is synchronous or awaits external work.

How do I query a declarative rule database and extract bound results in JavaScript?

To query a declarative rule database and extract results in JavaScript, define your facts and rules, then execute a query using the appropriate synchronous or asynchronous driver to retrieve all matching bound values.

When should I use backtracking search instead of standard branching in JavaScript?

You should use backtracking search in JavaScript when ordinary branching and filtering become hard to maintain. It is specifically useful for multi-solution reasoning tasks like expert-system style reasoning, policy checks, and authorization.
