Sprog

Nuget

Sprog (Danish for 'Language') cross-platform string parsing library written for C# 7+ and .NET Core.

Usage

Parsing a simple identifier

Parser TakeIdentifier(string input, out string _id) =>
    new Parser(input)
        .Skip(IsWhiteSpace)
        .Take(IsLetter, out char first)
        .Take(IsLetterOrDigit, out string rest)
        .Skip(IsWhiteSpace)
        .Let(_id = Concat(first, rest));

TakeIdentifier(" abc123  ", out var id);
Assert.AreEqual("abc123", id);

Sprog Naive XML parser

Performance

Preliminary results are promising, with performance nearly 30x faster than Sprache in a naive XML parsing benchmark, using far less memory and GC usage thanks to Sprogs reliance on the stack rather than heap allocation.
