🚀 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 result = new Validator(ast).validate();
console.log("Valid:", result.isValid);

Generate Code

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

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

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

🎓 Language Example

Input: system.spectral

type Task {
    id: string
    title: string
    status: TaskStatus
}

enum TaskStatus {
    todo
    in_progress
    done
}

role TaskManager {
    permission tasks {
        create,
        read,
        update,
        delete
    }
}

workflow TaskFlow {
    state todo -> in_progress
    state in_progress -> done
    state done -> archived
}

agent TaskAgent: TaskManager {
    can create task
    can update task when started
    can complete task if valid
}

visitor {
    can manage tasks {
        can create task
        can view tasks
        can update task
        can delete task
    }
}

Output: Generated TypeScript

// Auto-generated from Spectral language

export type Task = {
  id: string;
  taskStatus: string;
};

export enum TaskStatus {
  todo = "todo",
  in_progress = "in_progress",
  done = "done",
}

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

export class TaskAgentAgent {
  role: string = 'TaskManager';

  canCreateTask(): boolean {
    // TODO: Implement create task
    return true;
  }

  canUpdateTask(): boolean {
    // TODO: Implement update task
    return true;
  }

  canCompleteTask(): boolean {
    // TODO: Implement complete task
    return true;
  }
}

🎯 Usage Patterns

Pattern 1: Full Pipeline

const source = await Deno.readTextFile("spec.spectral");
const ast = new Parser(source).parse();
const valid = new Validator(ast).validate();
if (valid.isValid) {
  const code = new CodeGenerator(ast, { language: "typescript" }).generate();
}

Pattern 2: Quick Parse

const ast = new Parser(source).parse();

Pattern 3: Validation Only

const result = new Validator(new Parser(source).parse()).validate();

Pattern 4: Analysis

const report = analyzeSpectral(source);
console.log(report.summary);

Pattern 5: CLI

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

🔗 Integration Points

The Spectral tools integrate with:

1. Ouro CLI - Direct command support
2. Multi-Agent Systems - Generate agent code
3. Workflow Engines - Parse workflow definitions
4. Type Systems - Generate type definitions
5. Documentation - Auto-generate docs
6. Code Generators - Create implementation code

📝 Next Steps for Users

1. Create a .spectral file with your system definition
2. Parse it using new Parser(source).parse()
3. Validate using new Validator(ast).validate()
4. Generate code using new CodeGenerator(ast).generate()
5. Integrate the generated code into your system
6. Orchestrate multi-agent system based on definitions
