TypeRegex

Typified help in building regular expressions pattern.

Typified C# Regular Expressions Pattern.

TypeRegex is a CSharp library that helps to construct regular expressions patterns reducing typos and other common mistakes.

Installation

Use the package manager NuGet to install TypeRegex.

Install-Package TypeRegex

Usage

using TypeRegex;

public class Program
{
  public static void Main()
  {
    var pattern = new Pattern()
                    .AtStartOfStringOnly()
                    .Any()
                    .NewLine(true)
                    .AtEndOfStringOnly();
    
    Console.Write(pattern);

    // The example displays the following output:
    //    "\A[\u0000-\uFFFF]\u000D?\u000A\z"
  }
};
