Core functionality for polix - a DSL for writing declarative policies.

Polix provides a vector-based DSL for defining policies that evaluate against documents. Policies support document accessors (:doc/key), URI accessors (:uri/resource), function calls, and literals.

Quick Start

Define a policy:

(require '[polix.core :as polix])

(polix/defpolicy AdminOnly
  "Only admins can access"
  [:= :doc/role "admin"])

Evaluate a policy:

(let [document (polix/map-document {:role "admin"})
      result (polix/evaluate (:ast AdminOnly) document)]
  (cats.core/extract result))
  ;=> true

Main Concepts

• Document: Key-value store for policy evaluation data
• Policy: Declarative rule defined via defpolicy
• AST: Abstract syntax tree representation of policies
• Evaluator: Evaluates AST nodes against documents

Namespaces

The implementation is split across multiple namespaces:

• polix.document - Document protocol and implementations
• polix.ast - AST data structures
• polix.parser - Policy DSL parser
• polix.evaluator - Evaluation engine
• polix.policy - Policy definition macros
