Soenneker.Enumerables.CommaSeparated

Enumerates simple comma-delimited text as trimmed ReadOnlySpan<char> tokens without allocating a string or array for each value.

Install

dotnet add package Soenneker.Enumerables.CommaSeparated

Enumerate values

using Soenneker.Enumerables.CommaSeparated;

ReadOnlySpan<char> input = "alpha, beta, ,gamma";

foreach (ReadOnlySpan<char> token in new CommaSeparatedEnumerable(input))
{
    // token is "alpha", then "beta", then "gamma"
    Process(token);
}

Leading and trailing whitespace is trimmed from each token. Empty entries—including whitespace-only entries—are skipped. A null string constructor argument behaves like an empty input.

Parse without intermediate strings

Many framework parsing APIs accept spans directly:

var values = new CommaSeparatedEnumerable("10, 20, 30");
var total = 0;

foreach (ReadOnlySpan<char> value in values)
    total += int.Parse(value);

int count = values.Count(); // 3

Count() scans the input independently; it does not cache tokens. Calling it and then enumerating performs two passes.

Boundaries

This is not a CSV parser. Commas always delimit values, and quoting, escaped commas, embedded records, and alternate separators are not supported. Use a CSV library when inputs can contain those features.

Both the enumerable and enumerator are ref struct types. They cannot be boxed, stored on the heap, used across await or yield, or exposed as IEnumerable<T>. Each Current span points into the original input; call ToString() if a token must outlive that input or the current synchronous scope.
