warkanum a32647ee16 fix: writer/reader correctness and determinism issues

- merge: cloneTable keeps relationships; skip-tables applies to new schemas
- diff: detect schema description/owner changes
- prisma: reader no longer turns relation fields into columns, enum
  detection via declared names; writer type mapping is ordered
- typeorm writer: keep explicit SQL types that cannot be inferred
- drizzle: enum columns call the enum constant; reader resolves them
- mysql/mssql/sqlite writers: honour OutputPath, deterministic column
  and constraint order; mssql live execute covers full schema
- template: ToYAML recovers from panics; Merge nil-pointer loop
- regenerate drizzle fixtures

Prisma Reader

Reads Prisma schema files and extracts database schema information.

Overview

The Prisma Reader parses .prisma schema files that define database models using Prisma's schema language and converts them into RelSpec's internal database model representation.

Features

Parses Prisma schema syntax
Extracts models, fields, and relationships
Supports Prisma attributes and directives
Handles enums and composite types

Usage

Basic Example

package main

import (
    "fmt"
    "git.warky.dev/wdevs/relspecgo/pkg/readers"
    "git.warky.dev/wdevs/relspecgo/pkg/readers/prisma"
)

func main() {
    options := &readers.ReaderOptions{
        FilePath: "/path/to/schema.prisma",
    }

    reader := prisma.NewReader(options)
    db, err := reader.ReadDatabase()
    if err != nil {
        panic(err)
    }

    fmt.Printf("Found %d schemas\n", len(db.Schemas))
}

CLI Example

# Read Prisma schema and convert to JSON
relspec --input prisma --in-file schema.prisma --output json --out-file schema.json

# Convert Prisma to GORM models
relspec --input prisma --in-file schema.prisma --output gorm --out-file models.go

Example Prisma Schema

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

model User {
  id        Int      @id @default(autoincrement())
  username  String   @unique @db.VarChar(50)
  email     String   @db.VarChar(100)
  createdAt DateTime @default(now()) @map("created_at")

  posts Post[]

  @@map("users")
}

model Post {
  id      Int    @id @default(autoincrement())
  userId  Int    @map("user_id")
  title   String @db.VarChar(200)
  content String @db.Text

  user User @relation(fields: [userId], references: [id], onDelete: Cascade)

  @@map("posts")
}

Supported Prisma Attributes

@id - Primary key
@unique - Unique constraint
@default - Default value
@map - Column name mapping
@@map - Table name mapping
@relation - Relationship definition
@db.* - Database-specific type annotations

Notes

Extracts datasource provider information
Supports @@map for custom table names
Handles Prisma-specific types and converts them to standard SQL types
