Overt.Build

Overt mascot

Overt.Build is the MSBuild integration for the Overt language: a task + targets package that compiles .ov files alongside .cs files during dotnet build. Add the package to any SDK-style .csproj, drop .ov files into the project, and the generated C# is fed to Csc the same way any other Compile item is. Diagnostics surface in the IDE's error list as normal Csc errors.

Overt is an agent-first programming language: every effect, error, dispatch, mutation, and piece of state is overt, visible at the call or declaration site, never concealed. Transpiles to readable host-language source (C# today, Go planned).

Install

<ItemGroup>
  <PackageReference Include="Overt.Build" Version="0.2.0-dev.*" />
</ItemGroup>

Pre-release versions require a floating version range or an explicit version pin while Overt is in the 0.x.y dev channel.

Usage

Given a project MyApp.csproj with Overt.Build referenced, create Greeter.ov:

module greeter

fn greet(name: String) -> String {
    "hello, ${name}"
}

And call it from Program.cs:

using Overt.Generated.Greeter;

Console.WriteLine(Module.greet("world"));

dotnet build transpiles Greeter.ov, compiles the generated C# alongside your own, and links the final assembly. No manual steps, no codegen scripts.
