Main module for the Pattern library.

This module provides convenient access to all Pattern library functionality by re-exporting public APIs from core modules. Import this module to access all Pattern types, functions, and typeclass instances without needing to import individual modules.

Library Organization

The Pattern library is organized into several modules:

• Pattern.Core - Core Pattern data type, construction functions, query functions, predicate functions, the unified scope abstractions (ScopeQuery, TrivialScope, ScopeDict), and typeclass instances (Functor, Applicative, Comonad, etc.)
• Pattern.Graph - Low-level graph structural operations (GraphLens, fromGraphLens, nodes, relationships, incidentRels, etc.) and GraphView constructor toGraphView.
• Pattern.Graph.GraphQuery - Portable graph query interface (GraphQuery, TraversalWeight, combinators)
• Pattern.Graph.Types - GraphView and Substitution types (re-exported via Pattern.Graph)
• Pattern.Graph.Algorithms - Graph algorithms operating on GraphQuery (bfs, dfs, shortestPath, connectedComponents, etc.)
• Pattern.Graph.Transform - Bulk graph transformations: unfoldGraph, mapGraph, mapAllGraph, filterGraph, foldGraph, mapWithContext, the graph-scope reifier scopeDictFromGraphView, paraGraph, and paraGraphFixed
• Pattern.PatternGraph - Typed graph container with O(log n) lookups; fromPatternGraph, materialize, toGraphView
• Pattern.Reconcile - Pattern reconciliation for normalizing duplicate identities

Usage

Import the main Pattern module to access all functionality:

>>> import Pattern
>>> let p = point "test"
>>> value p
"test"

For graph transformation pipelines:

import Pattern
import Pattern.Graph.Transform (mapAllGraph, filterGraph, mapWithContext)
import Pattern.PatternGraph (toGraphView, materialize)

For graph algorithms, import the algorithm modules directly:

import Pattern.Graph.GraphQuery (directed)
import qualified Pattern.Graph.Algorithms as Alg

All public functions, types, and typeclass instances from Pattern.Core are available through this module. See individual module documentation for detailed information about specific functionality.

Re-export Structure

This module re-exports:

• All public exports from Pattern.Core (Pattern type, construction functions, query functions, predicate functions, helper functions, and all typeclass instances)
• All public exports from Pattern.Graph (graph operations, GraphView, Substitution)
• All public exports from Pattern.Graph.GraphQuery (portable graph query interface)
• All public exports from Pattern.Graph.Transform (bulk transformations and iterative algorithms)
• Selected exports from Pattern.PatternGraph (PatternGraph, mergeWithPolicy, fromPatterns, fromPatternsWithPolicy, empty, fromPatternGraph, materialize). For a GraphView from a PatternGraph use Pattern.PatternGraph.toGraphView; toGraphView for GraphLens is re-exported from Pattern.Graph.
• All public exports from Pattern.Reconcile (reconciliation operations)

Internal implementation details and helper functions are not exported through this module, ensuring a clean public API.
