Welcome to Mojee 🤪

What is Mojee?

Mojee is a lightning ⚡ fast Emoji library for .NET.

Mojee's big party trick is the ultra-high-performance parse and replacement of emoji :short-codes: within a block of text. Pass a string of text to Mojee, and Mojee will convert valid emoji :short-codes: into emoji characters. Here's a basic Mojee Replace sample:

// Replace all shortcodes with an emoji
var result = Mojee.Replace("Hello, world :smile:");

Console.WriteLine(result);

The console output from the above sample would be:

Hello, world 😄

Mojee is also amazing at Emoji search. Search for any term and Mojee will hand back a collection of emoji results. The following sample demonstrates a basic emoji search.

// Search for emojis
Mojee.Search("smile").ToList()
     .ForEach(emoji => Console.Write(emoji));

The console output from the above sample would be:

😄 😸 😃 😺 😅

Getting Started

Within seconds, Mojee can be added to any .NET Core project using the NuGet package, or search for Mojee from within the NuGet Package Manager in Visual Studio.

+++ dotnet CLI

dotnet add package Mojee

+++ NuGet CLI

Install-Package Mojee

+++

The following sequence of commands could be used to create a new .NET Console project using the dotnet CLI, add Mojee to the project, and finally open the new project in Visual Studio Code.

mkdir MojeeDemo          # Make a new folder
cd MojeeDemo             # Move into the new folder
dotnet new console       # Create a new .NET Console app
dotnet add package Mojee # Add Mojee to your new project
code .                   # Open in Visual Studio Code

The MojeeIO API is now available within your app. The following sample demonstrates a basic Console app scenario with Mojee.

using System;
using MojeeIO;

namespace MojeeDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            // Replace all shortcodes with an emoji
            var result = Mojee.Replace("Hello, world :+1:");

            Console.WriteLine(result);
            Console.ReadKey();
        }
    }
}

API Docs

Mojee Class

Replace static method

The static method Mojee.Replace will replace all emoji shortcodes in a string with Unicode emoji characters.

string Mojee.Replace(string text)

Argument	Type	Description
text	string	The input text to perform the replacement on.

Returns a new string with all matched :short-codes: replaced.

Example

var result = Mojee.Replace("Hello, world :smile:");

Console.WriteLine(result);

The Replace method also has a handy overload where an EmojiMatch evaluator can be passed. Each matched :short-code: found by Mojee is passed to the evaluator for custom processing.

string Mojee.Replace(string text, Func<EmojiMatch, string> evaluator)

Argument	Type	Description
text	string	The input text to perform the replacement on.
evaluator	Func<EmojiMatch, string>	The function evaluating a replacement string based on the matched Emoji. Returning null keeps the original capture as is.

Returns a new string with all matched :short-codes: replaced with the result from the evaluator.

A basic use-case for the evaluator would be logging each emoji match. In the following sample, we keep a simple count of the emoji shortcode matches that occur within a string.

Example

static void Main(string[] args)
{
    var count = 0;

    var result = Mojee.Replace(":+1: Hello, world :smile:", match =>
    {
        count++;

        // Any custom processing of the
        // emoji match can happen here.

        // Return the Emoji character
        return match.Emoji.Character;
    });

    Console.WriteLine($"Count: {count}");
    Console.WriteLine(result);

    Console.ReadKey();
}

The console output from the above sample would be:

Count: 2
👍 Hello, world 😄

Search static method

Search for emojis.

Search by any Shortcode substring ("cat"), or by an exact Emoji Shortcode (":smile:"), or if a Shortcode startsWith (":smi").

IEnumerable<Emoji> Mojee.Search(string query)

Argument	Type	Description
query	string	Any substring, exact Emoji Shortcode, or a Shortcode starting with.

Returns the matched Emoji instances as an IEnumerable<Emoji>.

Example

var result = Mojee.Search("smile");

result.ToList().ForEach(emoji =>
{
    Console.WriteLine($"{emoji}: {emoji.Shortcode}");
});

The console output from the above sample would be:

😄: :smile:
😃: :smiley:
😅: :sweat_smile:
😋: :yum:
😁: :grin:
😊: :blush:
😆: :laughing:
😍: :heart_eyes:
😈: :smiling_imp:

Console.Write($"{emoji.Shortcode}: {emoji}");
// smile: 😄

GetAll static method

Gets the list of all supported Emojis.

IReadOnlyList<Emoji> Emoji.GetAll()

Example

// Get the first 5 emojis
var emojis = Emoji.GetAll()
    .Take(5)
    .ToList();
