SwiftSoup A/B Benchmark

Repro script for comparing two commits with a heavier synthetic workload.

Usage:

bash swiftsoup-ab-bench.sh

Defaults (override with env vars):

This is straightforward, copy-pasted code from an app I'm building, where I needed to wrap NSCollectionView for SwiftUI.

It's really bad code, but it works at least.

SwiftNSCollectionView(items: ["a", "b", "a", "b", "a", "b", "a", "b", "a", "b", "a", "b", "a", "c"], itemSize: nil) { item in
     Text(item)
}

	private static let wordLikeRegex = /([A-Z]+[^A-Z\s_]+)\|(?:[\s_]\|^)+([^A-Z\s_]+)/

	/// Creates a copy of the current string by turning into snake case
	///
	/// ## Example
	/// ```swift
	/// // Outputs: my_spaced_name24_long_string
	/// "My SpacedName24_Long_____String".snakeCased()
	/// ```

	float2 distort(float2 uv, float strength) {
	float2 dist = 0.5 - uv;
	uv.x = (uv.x - dist.y * dist.y * dist.x * strength);
	uv.y = (uv.y - dist.x * dist.x * dist.y * strength);
	return uv;
	}
