VS Code & NuGet

The IDE is one way to write sketches. The same sketches also run from VS Code with the DanaProcessing extension, and inside any .NET project with the NuGet packages. A sketch file copied out of the IDE runs as it is in both.

The VS Code extension

Install DanaProcessing from the Extensions view (or the .vsix from the releases), plus the .NET 10 SDK and the C# extension. Then, from the Command Palette (Ctrl+Shift+P), type DanaProcessing:

New Sketch creates a project ready to run; Open an Example turns any of the IDE's examples into one, with its NuGet packages.
Run Sketch (▶, Ctrl+Alt+R) opens it in its own window. Live (⚡, Ctrl+Alt+L) keeps it running with dotnet watch and applies your edits when you save. Stop is Ctrl+Alt+S. Errors land in the Problems panel.
Export as an App makes one file per system (Windows, macOS, Linux) that runs without .NET installed, in export/<platform>/, with the data/ folder.
// nuget: NAudio, 2.2.1 lines, as the IDE writes them, become package references when you run. Make This Sketch Runnable creates the project for a .cs saved from the IDE; Open in the DanaProcessing IDE goes the other way.
Open the Reference (Ctrl+Alt+H) shows the page of the name under the cursor, and hovering a DanaProcessing name links to it. Snippets: sketch, setup, draw, mousePressed, keyPressed, grid, push, nuget.

The extension speaks English and Spanish: it follows VS Code's display language.

dotnet new dana-sketch

Without VS Code, the template makes the same project from a terminal:

dotnet new install DanaProcessing.Templates
dotnet new dana-sketch -n MySketch
cd MySketch
dotnet run          # or: dotnet watch run, to live-code

The NuGet packages

Package	What it is
`DanaProcessing`	The core: `Sketch`, 2D and 3D drawing, sound, `PVector`, `PImage`, math. No windows: draw off-screen, in tests or on a server.
`DanaProcessing.AvaloniaHost`	The window: `SketchApp.Run()` and the `AvaloniaSketchCanvas` control. Windows, macOS and Linux.
`DanaProcessing.Templates`	The `dana-sketch` template for `dotnet new`.

Add a sketch to a program you already have:

dotnet add package DanaProcessing.AvaloniaHost

using DanaProcessing.AvaloniaHost;

SketchApp.Run(new Bubbles());

public class Bubbles : Sketch
{
    public override void Setup() => Size(400, 400);
    public override void Draw()
    {
        Background(20);
        Circle(MouseX, MouseY, 40);
    }
}

Projects with ImplicitUsings get using DanaProcessing; for free, like the IDE (turn it off with <DanaProcessingImplicitUsings>false</DanaProcessingImplicitUsings>). To put a sketch inside your own Avalonia window, see AvaloniaSketchCanvas.
