Mure: MUlti-valued Regular Expressions

Overview

Mure is a text stream matching engine with support for a subset of regular expressions, able to bind several patterns to a corresponding value and return the one value associated to matched pattern. This allows forward-only text parsing while mapping each matched sequence to corresponding value, which is a efficient solution for tokenization tasks e.g. when writing lexers.

Usage

There is no user documentation available yet, sorry!

Here is a simple code sample:

var matcher = Compiler
    .CreateFromRegex<LexemType>()
    .AddPattern("[0-9]+", LexemType.Number)
    .AddPattern("\\+", LexemType.Plus)
    .AddPattern("-", LexemType.Minus)
    .Compile();

using (var reader = new StringReader("27+32-4"))
{
    var iterator = matcher.Open(reader);

    while (iterator.TryMatchNext(out var match))
        Console.WriteLine($"Matched {match.Value}: {match.Capture}");
}

Running this code will print to standard output:

Matched Number: 27
Matched Plus: +
Matched Number: 32
Matched Minus: -
Matched Number: 4
