🚀 Quick Start

Parse a Spectral File

import { Parser } from "@aexol/ouro/spectral";

const source = await Deno.readTextFile("system.spectral");
const ast = new Parser(source).parse();

Validate

import { Validator } from "@aexol/ouro/spectral";

const validator = new Validator(ast);
const result = validator.validate();

if (!result.isValid) {
  console.error("Errors:", result.errors);
}

Generate Code

import { CodeGenerator } from "@aexol/ouro/spectral";

const generator = new CodeGenerator(ast, { language: "typescript" });
const code = generator.generate();
console.log(code);

CLI Usage

# Parse
deno run -A src/commands/spectral.ts parse --input system.spectral

# Validate
deno run -A src/commands/spectral.ts validate --input system.spectral

# Generate TypeScript
deno run -A src/commands/spectral.ts generate \
  --input system.spectral \
  --language typescript \
  --output generated.ts

# Generate documentation
deno run -A src/commands/spectral.ts docs \

📖 Language Example

Input: system.spectral

# Define types
type Document {
    id: string
    title: string
    status: DocumentStatus
}

enum DocumentStatus {
    draft
    review
    published
}

# Define roles
role Editor {
    permission documents {
        create,
        read,
        update,
        delete
    }
}

# Define workflows
workflow Publishing {
    state draft -> review
    state review -> published
    state published -> archived
}

# Define agents
agent ContentProcessor: Editor {
    can fetch document
    can validate content
    can publish document if approved
}

# Define visitor patterns
visitor {
    can manage documents {
        can create document
        can view documents
        can edit document if owner
        can delete document if owner
    }
}

Output: Generated TypeScript

// Auto-generated from Spectral language

export type Document = {
  id: string;
  title: string;
  status: DocumentStatus;
};

export enum DocumentStatus {
  draft = "draft",
  review = "review",
  published = "published",
}

export class EditorRole {
  static readonly permissions = {
    documents: ['create', 'read', 'update', 'delete'],
  };
}

export class ContentProcessorAgent {
  role: string = 'Editor';

  canFetchDocument(): boolean {
    // TODO: Implement fetch document
    return true;
  }

  canValidateContent(): boolean {
    // TODO: Implement validate content
    return true;
  }

  canPublishDocument(): boolean {
    // TODO: Implement publish document
    return true;
  }
}

🏗️ Architecture

Processing Pipeline

Source Code
    ↓
[Lexer] → Tokens (50+ types)
    ↓
[Tokenizer] → Token Stream (with lookahead)
    ↓
[Parser] → AST (14+ node types)
    ↓
[Validator] → Validation Result
    ↓
[CodeGenerator] → Implementation Code
    ↓
[Utilities] → Analysis & Visualization

Design Patterns

• Lexer-Tokenizer-Parser: Standard pipeline
• Recursive Descent: Predictable parsing
• Error Recovery: Continue after errors
• Modular Design: Each phase independent
• Stream-Based: Efficient token access
