:+1: This PR looks great - it's ready to merge! :shipit:

👍 This PR looks great - it's ready to merge!

GEmojiSharp make this possible in C#. The library contains a static array of all valid emoji in GitHub Flavored Markdown. That is the intersection of the emoji.json database and the API with available emojis.

GitHub Emoji for C# and .NET 📦

Static methods:

Emoji.Get(":tada:").Raw; // 🎉
Emoji.Get("🎉").Alias(); // :tada:
Emoji.Raw(":tada:"); // 🎉
Emoji.Alias("🎉"); // :tada:
Emoji.Emojify(":tada: initial commit"); // 🎉 initial commit
Emoji.Demojify("🎉 initial commit"); // :tada: initial commit
Emoji.Find("party popper").First().Raw; // 🎉
Emoji.Get("✌️").RawSkinToneVariants(); // ✌🏻, ✌🏼, ✌🏽, ✌🏾, ✌🏿

Extension methods:

":tada:".GetEmoji().Raw; // 🎉
"🎉".GetEmoji().Alias(); // :tada:
":tada:".RawEmoji(); // 🎉
"🎉".EmojiAlias(); // :tada:
":tada: initial commit".Emojify(); // 🎉 initial commit
"🎉 initial commit".Demojify(); // :tada: initial commit
"party popper".FindEmojis().First().Raw; // 🎉

Regular expression pattern to match all emojis:

var text = "Lorem 😂😂 ipsum";

var matches = Regex.Matches(text, Emoji.RegexPattern);
string.Join(string.Empty, matches.Select(x => x.Value)); // 😂😂

Regex.Replace(text, Emoji.RegexPattern, string.Empty); // Lorem  ipsum

GitHub Emoji for ASP.NET Core 📦

The package includes:

• TagHelpers
• HtmlHelpers

Update the _ViewImports.cshtml file, to enable tag helpers in all Razor views:

@addTagHelper *, GEmojiSharp.AspNetCore

Use the <emoji> tag or emoji attribute to render emojis:

<span emoji=":tada:"></span>
<emoji>:tada: initial commit</emoji>

Standard emoji characters are rendered like this:

<g-emoji class="g-emoji" alias="tada" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f389.png">🎉</g-emoji>

Custom GitHub emojis are rendered as images:

<img class="emoji" title=":octocat:" alt=":octocat:" src="https://github.githubassets.com/images/icons/emoji/octocat.png" height="20" width="20" align="absmiddle">

Use CSS to properly position the custom GitHub emojis images:

.emoji {
    background-color: transparent;
    max-width: none;
    vertical-align: text-top;
}

Use the JavaScript from g-emoji-element to support old browsers.

Backports native emoji characters to browsers that don't support them by replacing the characters with fallback images.

Add a libman.json file:

{
  "version": "1.0",
  "defaultProvider": "cdnjs",
  "libraries": [
    {
      "provider": "unpkg",
      "library": "@github/[email protected]",
      "destination": "wwwroot/lib/g-emoji-element/"
    }
  ]
}

And add the script to the _Layout.cshtml file:

<script src="~/lib/g-emoji-element/dist/index.js"></script>

Do you want to use emoji anywhere, on any tag, in the body? Then you can use the BodyTagHelperComponent.

Use any tag to render emojis:

<h1>Hello, :earth_africa:</h1>

Registration via services container:

using GEmojiSharp.AspNetCore;
using Microsoft.AspNetCore.Razor.TagHelpers;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddRazorPages();
builder.Services.AddTransient<ITagHelperComponent, BodyTagHelperComponent>();

Registration via Razor file:

@page
@model GEmojiSharp.Sample.Web.Pages.ComponentModel
@using Microsoft.AspNetCore.Mvc.Razor.TagHelpers
@using GEmojiSharp.AspNetCore
@inject ITagHelperComponentManager manager;
@{
    ViewData["Title"] = "Component";
    manager.Components.Add(new BodyTagHelperComponent());
}

Registration via Page Model or controller:

using GEmojiSharp.AspNetCore;
using Microsoft.AspNetCore.Mvc.Razor.TagHelpers;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace GEmojiSharp.Sample.Web.Pages
{
    public class ComponentModel : PageModel
    {
        private readonly ITagHelperComponentManager _tagHelperComponentManager;

        public IndexModel(ITagHelperComponentManager tagHelperComponentManager)
        {
            _tagHelperComponentManager = tagHelperComponentManager;
        }

        public void OnGet()
        {
            _tagHelperComponentManager.Components.Add(new BodyTagHelperComponent());
        }
    }
}

Update the _ViewImports.cshtml file, to enable HTML helpers in all Razor views:

@using GEmojiSharp.AspNetCore

Use the Emoji extension methods to render emojis:

@Html.Emoji(":tada: initial commit")
@Html.Emoji(x => x.Text)

GitHub Emoji for Blazor 📦

The package is a Razor class library (RCL) with a Razor component.

Update the _Imports.razor file, to enable the component in all Razor views:

@using GEmojiSharp.Blazor

Set the global render mode in App.razor:

<Routes @rendermode="InteractiveServer" />

or per page/component:

@rendermode InteractiveServer

Use the <Emoji> component to render emojis:

<Emoji>:tada: initial commit</Emoji>

Standard emoji characters are rendered like this:

<g-emoji class="g-emoji" alias="tada" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f389.png">🎉</g-emoji>

Custom GitHub emojis are rendered as images:

<img class="emoji" title=":octocat:" alt=":octocat:" src="https://github.githubassets.com/images/icons/emoji/octocat.png" height="20" width="20" align="absmiddle">
