DDK — Data Definition Kit

Language support for SUQABASE DDK schema files (.ddk).

Features

• Syntax highlighting — models, enums, fields, types, attributes (@id, @unique, @default, etc.)
• Code completion — keywords, types, attributes, decorators (@@index, @@map, etc.)
• Real-time diagnostics — parse errors, semantic errors, validation warnings
• Hover info — type and attribute information on hover
• Document symbols — structured outline of models, enums, and fields

Requirements

The LSP server (ddk-lsp) must be built from the Rust workspace:

cargo build -p ddk-lsp

The extension automatically finds the binary in target/release/ or target/debug/ of the workspace root.

Usage

1. Open any .ddk file
2. Syntax highlighting activates immediately
3. LSP features (completions, diagnostics, hover) start automatically when the ddk-lsp binary is found

Commands

• DDK: Open LSP Output — opens the LSP output channel for debugging

Settings

Examples

/// User model
model User {
  id        Int      @id @default(autoincrement())
  email     String   @unique @format(email)
  name      String   @min(2) @max(100)
  role      Role     @default(USER)
  createdAt DateTime @default(now())
  updatedAt DateTime @default(now())

  @@index([email, role])
  @@map("users")
}

enum Role {
  USER
  ADMIN
}

model Post {
  id        Int      @id @default(autoincrement())
  title     String   @max(200)
  content   Text?
  published Boolean  @default(false)
  authorId  Int
  author    User     @relation(authorId)
