Repost — VS Code extension

Language support for the Repost webhook schema language (.repost) — a Prisma-derived DSL for declaring webhook event catalogs, payload models and the Standard Webhooks envelope. If you know Prisma schema, you already know this.

generator sdk {
  provider = "typescript"
  output   = "../generated/webhooks"
}

type Book {
  /// A book was created
  created // -> "book.created"
}

model Book {
  title    String
  authors  Author[]
  price    Float
  currency Currency
}

event BookCreated {
  type      @type(Book.created)
  data      Book
  timestamp DateTime
}

Features

• Syntax highlighting — keywords (generator/model/enum/type/event), field types and arities, attributes (@type/@map/@default/@deprecated), strings, and // / /// doc comments.
• Diagnostics — schema validation as you type (missing/duplicate @type, unknown types, envelope violations, unbound catalog members, and more).
• Completion — catalog members inside @type(Catalog.…), attribute names after @ (context-aware: @type only inside event blocks), block keywords, and field types. Trigger characters: @, ", ..
• Formatting — canonical, column-aligned reformatting (Shift+Alt+F).

All analysis runs locally through a WebAssembly build of the repost-schema engine bundled inside the extension; nothing is sent anywhere and no external CLI is required.

Requirements

VS Code 1.85 or newer. No other tooling is needed — the language server and its WebAssembly engine ship inside the extension.

Marketplace identifiers

Note: the publisher (repost), extension ID (repost.repost) and display name (Repost) are fixed for Marketplace publishing. The language ID repost and TextMate scope source.repost are fixed as well. Publishing itself is handled by the repository release workflow.
