Slugify.Core 3.0.0

Slugify Core

This is a fork of the original project here: https://github.com/fcingolani/Slugify. This has been updated for .NET Standard 2.0 support (older versions support .NET Standard down to 1.3).

Simple Slug / Clean URL generator helper for Microsoft .NET framework.

With default settings, you will get an hyphenized, lowercase, alphanumeric version of any string you please, with any diacritics removed and collapsed whitespace, collapsed dashes and trimmed whitespace.

In example, having:

a ambição cerra o coração

You'll get:

a-ambicao-cerra-o-coracao

Installation

You can get the Slugify NuGet package by running the following command in the Package Manager Console:

PM> Install-Package Slugify.Core

Upgrading from 2.x to 3.x

• 3.0 is a significantly faster and less memory intensive version of the Slugifier. Whilst effort has been made to maintain backwards compatability, there may be some breaking changes.
• The SlugHelper.Config nested class has been renamed to just SlugHelperConfiguration.

Basic Usage

It's really simple! Just instantiate SlugHelper and call its GenerateSlug with the string you want to convert; it'll return the URL Safe version:

using Slugify;

public class MyApp
{
   public static void Main()
   {
      SlugHelper helper = new SlugHelper();

      String title = "OLA ke ase!";

      String slug = helper.GenerateSlug(title); // "ola-ke-ase"

      Console.WriteLine(slug);
   }
}

Configuration

You can provide a SlugHelperConfiguration instance to SlugHelper's constructor to customize the helper's behavior:

// Creating a configuration object
var config = new SlugHelperConfiguration();

// Replace spaces with a dash
config.StringReplacements.Add(" ", "-");

// We want a lowercase Slug
config.ForceLowerCase = true;

// Will collapse multiple seqential dashes down to a single one
config.CollapseDashes = true;

// Will trim leading and trailing whitespace
config.TrimWhitespace = true;

// Colapse consecutive whitespace chars into one
config.CollapseWhiteSpace = true;

// Remove everything that's not a letter, number, hyphen, dot, or underscore
config.DeniedCharactersRegex = @"[^a-zA-Z0-9\-\._]";

// Create a helper instance with our new configuration
SlugHelper helper = new SlugHelper(config);

In fact, the above values are so common they're the default ones! So last code could be rewritten as:

var config = new SlugHelperConfiguration();
SlugHelper helper = new SlugHelper(config);

One more thing: SlugHelperConfiguration is used when you call the parameterless SlugHelper constructor. Then ...

SlugHelper helper = new SlugHelper();

... is the same as running the code we had in first place.

Options

CharacterReplacements

Type: Dictionary<String, String>. Default: [" ": "-"].

Will replace the specified keys with their associated value.

By default, will replace spaces with hyphens.

ForceLowerCase

Type: Boolean. Default: true.

Setting it to true will convert output string to be LowerCase. If false, original casing will be preserved.

CollapseWhiteSpace

Type: Boolean. Default: true.

Setting it to true will replace consecutive whitespace characters by just one space (" ").

DeniedCharactersRegex

Type: String. Default: [^a-zA-Z0-9-._].

Any character matching this Regular Expression will be deleted from the resulting string.

CollapseDashes

Type: Boolean. Default: true

This will condense multiple dashes (e.g. foo---bar) down to a single dash (foo-bar). This is useful to avoid scenarios like foo & bar becoming foo--bar.
