Farkle

Farkle is a .NET library for building fast, reliable text parsers in F# and C#. It creates LALR(1) and IELR(1) parsers through an API that resembles parser combinators, letting you define grammars directly in source code without requiring a separate grammar definition language.

Farkle can also generate parsing tables at build time, providing fast startup performance on par with generated parsers, and compile-time grammar validation. Check out the Farkle.Tools.MSBuild package for more information.

Quick Start

C#

using Farkle;
using Farkle.Builder;

var number = Terminals.Int32("Number");
var expression = Nonterminal.Create("Addition",
    number.Extended().Append("+").Extend(number).Finish((left, right) => left + right)
);

var parser = expression.Build();
var result = parser.Parse("1 + 2"); // Whitespace is ignored by default.
Console.WriteLine(result); // 3

F#

open Farkle
open Farkle.Builder

let number = Terminals.Int32("Number")
let expression = "Addition" ||= [
    !@ number .>> "+" .>>. number => (fun left right -> left + right)
]

let parser = GrammarBuilder.build expression
let result = CharParser.parseString parser "1 + 2" // Whitespace is ignored by default.
printfn "%O" result // 3
