• ✅ System Variables Support: Built-in variables ({{$guid}}, {{$randomInt}}, {{$timestamp}}, {{$datetime}})
• ✅ Enhanced Expectation Comments: Parse # @expect-* comments for automated testing
• ✅ Request Parsing: Robust HTTP request parsing with headers, body, and metadata
• ✅ Name-Based API: Complete request lookup and validation API
• ✅ Comprehensive Error Handling: Detailed validation with clear error messages
• 🚧 ASP.NET Core Integration: Testing framework for integration tests (in progress)

📦 Packages

• RESTClient.NET.Core - Core parsing library (✅ Production Ready)
• RESTClient.NET.Testing - ASP.NET Core testing framework (🚧 In Progress)
• RESTClient.NET.Extensions - Additional utilities and extensions (📋 Planned)

🛠️ Installation

# Core library
dotnet add package RESTClient.NET.Core

# Testing framework (coming soon)
dotnet add package RESTClient.NET.Testing

📖 Quick Start

Basic Parsing

using RESTClient.NET.Core;

var parser = new HttpFileParser();
var httpFile = await parser.ParseAsync("requests.http");

// Get request by name
var loginRequest = httpFile.GetRequestByName("login");
Console.WriteLine($"Method: {loginRequest.Method}");
Console.WriteLine($"URL: {loginRequest.Url}");

// Access expectations
foreach (var expectation in loginRequest.Metadata.Expectations)
{
    Console.WriteLine($"Expectation: {expectation.Type} = {expectation.Value}");
}

HTTP File Format

@baseUrl = https://api.example.com
@apiVersion = v1

# @name login
# @expect status 200
# @expect header Content-Type application/json
# @expect body-contains "token"
POST {{baseUrl}}/{{apiVersion}}/auth/login HTTP/1.1
Content-Type: application/json
X-Request-ID: {{$guid}}
X-Timestamp: {{$timestamp}}

{
    "username": "user@example.com",
    "password": "secure_password",
    "sessionId": "{{$randomInt 1000 9999}}"
}

# @name get-user-profile
# @expect status 200
# @expect body-path $.id
GET {{baseUrl}}/{{apiVersion}}/users/me HTTP/1.1
Authorization: Bearer {{login.response.body.$.token}}
Accept: application/json
X-Client-Time: {{$datetime iso8601}}
