Veggerby.Units.CodeFixes

Code fix providers for the Veggerby.Units.Analyzers diagnostics.

This package supplies IDE (Roslyn) code actions that complement the analyzer warnings/errors:

Diagnostic	Code Fix Action	Effect
VUNITS001	"Convert right operand to left unit"	Inserts .ConvertTo(left.Unit) on the right-hand side of a + / - operation between differing unit measurements.
VUNITS002	"Specify UnitFormat.Qualified"	Adds UnitFormat.Qualified argument to measurement formatting calls lacking explicit format.

When to Install

Install this package if you want automated fixes in Visual Studio / Rider / VS Code C# extension. The analyzers package (Veggerby.Units.Analyzers) is still required to produce diagnostics; this package only contributes fixes.

In most solutions reference both:

<ItemGroup>
  <PackageReference Include="Veggerby.Units" Version="$(VeggerbyUnitsVersion)" />
  <PackageReference Include="Veggerby.Units.Analyzers" Version="$(VeggerbyUnitsAnalyzersVersion)" PrivateAssets="all" />
  <PackageReference Include="Veggerby.Units.CodeFixes" Version="$(VeggerbyUnitsCodeFixesVersion)" PrivateAssets="all" />
</ItemGroup>

PrivateAssets="all" prevents re‑distribution of analyzer/code fix assets to downstream consumers unless explicitly desired.

Usage Examples

VUNITS001

Before:

var len = new DoubleMeasurement(5, Unit.SI.m);
var time = new DoubleMeasurement(3, Unit.SI.s);
var bad = len + time; // diagnostic VUNITS001

Fix applies:

var fixedValue = len + time.ConvertTo(len.Unit);

VUNITS002

Before:

var energy = new DoubleMeasurement(1, Unit.SI.kg * Unit.SI.m * Unit.SI.m / (Unit.SI.s ^ 2));
var s = energy.ToString(); // diagnostic VUNITS002

Fix applies:

var s2 = energy.Format(UnitFormat.Qualified);

Relationship to Analyzer Package

The analyzers assembly is intentionally kept free of Microsoft.CodeAnalysis.Workspaces to satisfy RS1038 guidance. Code fixes depend on Workspaces APIs and therefore live in this separate package. Both share internal diagnostic descriptors via InternalsVisibleTo.
