import PackageDescription

// Standalone engine for the Fabric Math Expression node: the MathExpressionEngine
// target has no package dependencies and no Fabric / Metal / Satin, so a host that
// evaluates expressions links nothing else, and the correctness suite runs with no
// GPU or app. Transforms/quaternions use Apple `simd` at the port boundary, so it
// targets Apple platforms.
//
// MathExpressionEditorSupport is a second product, for a host that edits expressions
// rather than only evaluating them. It is what pulls in CodeEditorView: a host that
// does not link it does not build it, though running this package's own tests does.
// The platform floor below is CodeEditorView's, and SwiftPM declares platforms per
// package rather than per target, so the engine target carries it too.
