// Package relspecgo provides bidirectional conversion between database schema formats.
//
// RelSpec is a comprehensive database schema tool that reads, writes, and transforms
// database schemas across multiple formats including live databases, ORM models,
// schema definition languages, and data interchange formats.
//
// # Features
//
//   - Read from 15+ formats: PostgreSQL, SQLite, DBML, GORM, Prisma, Drizzle, and more
//   - Write to 15+ formats: SQL, ORM models, schema definitions, JSON/YAML
//   - Interactive TUI editor for visual schema management
//   - Schema diff and merge capabilities
//   - Format-agnostic intermediate representation
//
// # Architecture
//
// RelSpec uses a hub-and-spoke architecture with models.Database as the central type:
//
//	Input Format → Reader → models.Database → Writer → Output Format
//
// This allows any supported input format to be converted to any supported output format
// without requiring N² conversion implementations.
//
// # Key Packages
//
//   - pkg/models: Core data structures (Database, Schema, Table, Column, etc.)
//   - pkg/readers: Input format readers (dbml, pgsql, gorm, etc.)
//   - pkg/writers: Output format writers (dbml, pgsql, gorm, etc.)
//   - pkg/ui: Interactive terminal UI for schema editing
//   - pkg/diff: Schema comparison and difference detection
//   - pkg/merge: Schema merging utilities
//   - pkg/transform: Validation and normalization
//
// # Installation
//
//	go install git.warky.dev/wdevs/relspecgo/cmd/relspec@latest
//
// # Usage
//
// Command-line conversion:
//
//	relspec convert --from dbml --from-path schema.dbml \
//	                --to gorm --to-path ./models
//
// Interactive editor:
//
//	relspec edit --from pgsql --from-conn "postgres://..." \
//	             --to dbml --to-path schema.dbml
//
// Schema comparison:
//
//	relspec diff --source-type pgsql --source-conn "postgres://..." \
//	             --target-type dbml --target-path schema.dbml
//
// Merge schemas:
//
//	relspec merge --target schema1.dbml --sources schema2.dbml,schema3.dbml
//
// # Supported Formats
//
// Input/Output Formats:
//   - dbml: Database Markup Language
//   - dctx: DCTX schema files
//   - drawdb: DrawDB JSON format
//   - graphql: GraphQL schema definition
//   - json: JSON schema representation
//   - yaml: YAML schema representation
//   - gorm: Go GORM models
//   - bun: Go Bun models
//   - drizzle: TypeScript Drizzle ORM
//   - prisma: Prisma schema language
//   - typeorm: TypeScript TypeORM entities
//   - pgsql: PostgreSQL (live DB or SQL)
//   - sqlite: SQLite (database file or SQL)
//
// # Library Usage
//
// RelSpec can be used as a Go library:
//
//	import (
//	    "git.warky.dev/wdevs/relspecgo/pkg/models"
//	    "git.warky.dev/wdevs/relspecgo/pkg/readers/dbml"
//	    "git.warky.dev/wdevs/relspecgo/pkg/writers/gorm"
//	)
//
//	// Read DBML
//	reader := dbml.NewReader(&readers.ReaderOptions{
//	    FilePath: "schema.dbml",
//	})
//	db, err := reader.ReadDatabase()
//
//	// Write GORM models
//	writer := gorm.NewWriter(&writers.WriterOptions{
//	    OutputPath:  "./models",
//	    PackageName: "models",
//	})
//	err = writer.WriteDatabase(db)
