Quick Start Guide

Install BatchSharp

BatchSharp can be installed using the Nuget package manager or the dotnet CLI.
- Package Manager
```
Install-Package BatchSharp
```
- dotnet CLI
```
dotnet add package BatchSharp
```

Create processor class

using BatchSharp.Processor;

 namespace BatchSharp.Example.Processor;

 public class ExampleProcessor : IProcessor<string, int>
 {
     // Convert input data to output data
     // This method is called for each input data
     public int Process(string source)
     {
         return source.Length;
     }
 }

Create the main class

Configure input and output type of batch application. And register processor class that convert input data to output data.

using BatchSharp;
using BatchSharp.Example;
using BatchSharp.Example.Processor;
using BatchSharp.Example.Reader;
using BatchSharp.Example.Writer;
using BatchSharp.Processor;
using BatchSharp.Reader;
using BatchSharp.Writer;

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var builder = Host.CreateDefaultBuilder(args)
    .ConfigureHostConfiguration(builder =>
    {
        // Add BatchSharp configuration
        builder.AddBatchConfiguration();
    })
    .ConfigureServices((_, services) =>
    {
        services.AddHostedService<BatchHostedService>();
        services.AddScoped<IBatchApplication, ExampleBatchApplication>();
        // Register reader setting
        services.AddScoped<IFileReaderSetting, FlatFileReaderSetting>( c => new FlatFileReaderSetting("input.txt"));
        // Register reader class
        services.AddScoped<IReader<string>, FlatFileReader>();
        // Register processor class
        services.AddScoped<IProcessor<string, int>, ExampleProcessor>();
        // Register writer setting
        services.AddScoped<IFileWriterSetting, FileWriterSetting>(c => new FileWriterSetting("output.txt"));
        // Register writer class
        services.AddScoped<IWriter<int>, ExampleWriter>();
        services.AddScoped<IStep, SimpleStep<string, int>>();
        services.AddScoped<IStepState, StepState>();
    });

var app = builder.Build();
await app.RunAsync();

Run batch application
```
dotnet run
```
