Syntax Transformer

Description

Tool containing a collection of Syntax Transformers capable of rewriting C# code syntax from the AST level. Transformers analyze syntax from the AST and perform updates based on the evaluated nodes / node types. Syntax Transformations are built using Roslyn Analyzers

Use Case

The transformers are intended to allow quickly creating new projects by auto-generating boiler plate code.

Install the Nuget package

After adding the package source the project can be installed similar to any nuget package.

dotnet tool install SyntaxTransformer -v <target_version>

Usage

The tool can then be ran using the dotnet cli such as:

dotnet syntax-transformer <target-directory>

Example Usage

Given an ASP.NET Controller class such as:

public HomeController : ControllerBase
{
    private readonly DataContext _context;
    ...
    public IActionResult GetViewModel() => Ok(_context.ViewModels.FirstOrDefault());
}

Will be transformed to

[Authorize]
[ApiController]
[Route("api/[controller]")]
public HomeController : ControllerBase
{
    private readonly DataContext _context;
    ...
    [HttpGet]
    [ProducesResponseType(typeof(OkObjectResult), 200)]
    public IActionResult GetViewModel() => Ok(_context.ViewModels.FirstOrDefault());
}
