ScriptSourceGenerator 1.0.5

ScriptSourceGenerator

This geneator can compile and run csx files and generate files from csx scripts using Roslyn scripting.

Usage

• Add nuget package into your project
• Add a .csx script file into project:

var httpClient = new HttpClient();
var result = await client.GetStringAsync("http://www.github.com");

• Change .csx file Build Action property to C# analyzer additional file or modify csproj like this:

<ItemGroup>
	<None Remove="MyScript.csx" />
	<AdditionalFiles Include="MyScript.csx" />
</ItemGroup>

• If you want to create files as an output, you can use global Output indexer property which is a StringBuilder:

Output["Github.html"].Append(result);

• Even you can create .cs files to generate compile time source codes:

Output["MyModel.cs"].AppendLine("""
public class MyModel
{
""");
for(var i=0; i < 5; i++)
{
    Output["MyModel.cs"].AppendLine($$"""
        public string Prop{{i}} { get; set; } 
    """);
}

Output["MyModel.cs"].AppendLine("}");

and it will be generate this file:

public class MyModel
{
    public string Prop0 { get; set; }
    public string Prop1 { get; set; }
    public string Prop2 { get; set; }
    public string Prop3 { get; set; }
    public string Prop4 { get; set; }
}

• To add assembly references and nuget references use #r directives:

#r "nuget:Microsoft.OpenApi.Readers/1.4.5"
#r "System.Net.Http"
using System;
using System.Net.Http;
using Microsoft.OpenApi;
using Microsoft.OpenApi.Extensions;
using Microsoft.OpenApi.Readers;

var httpClient = new HttpClient
{
    BaseAddress = new Uri("https://raw.githubusercontent.com/OAI/OpenAPI-Specification/")
};

var stream = await httpClient.GetStreamAsync("master/examples/v3.0/petstore.yaml");

// Read V3 as YAML
var openApiDocument = new OpenApiStreamReader().Read(stream, out var diagnostic);

// Write V2 as JSON
var outputString = openApiDocument.Serialize(OpenApiSpecVersion.OpenApi2_0, OpenApiFormat.Json);
Output["GeneratedModels.cs"].Append(outputString);

• External csx files can be imported with #load directive

#load "AnotherFile.csx"
using AnotherNamespace.In.AnotherFile;
