work with emoji in the most convenient way

GoMoji is a Go package that provides a fast and simple way to work with emojis in strings. It has features such as:

• check whether string contains emoji,

• get all emojis,

Getting Started

Installing

To start using GoMoji, install Go and run go get:

$ go get -u github.com/forPelevin/gomoji

This will retrieve the package.

Check string contains emoji

package main

import (
    "github.com/forPelevin/gomoji"
)

func main() {
    res := gomoji.ContainsEmoji("hello world")
    println(res) // false
    
    res = gomoji.ContainsEmoji("hello world 🤗")
    println(res) // true
}

Find all

The function searches for all emoji occurrences in a string. It returns a nil slice if there are no emojis.

package main

import (
    "github.com/forPelevin/gomoji"
)

func main() {
    res := gomoji.FindAll("🧖 hello 🦋 world")
    println(res)
}

Get all

The function returns all existed emojis. You can do whatever you need with the list.

package main

import (
    "github.com/forPelevin/gomoji"
)

func main() {
    emojis := gomoji.AllEmojis()
    println(emojis)
}

Emoji entity

All searching methods return the Emoji entity which contains comprehensive info about emoji.

type Emoji struct {
    Slug        string `json:"slug"`
    Character   string `json:"character"`
    UnicodeName string `json:"unicode_name"`
    CodePoint   string `json:"code_point"`
    Group       string `json:"group"`
    SubGroup    string `json:"sub_group"`

[]gomoji.Emoji{
    {
