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
• find all emojis in string
• get all emojis
• remove all emojis from string
• get emoji description

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)
}

Result:

[]gomoji.Emoji{
    {
        Slug:        "person-in-steamy-room",
        Character:   "🧖",
        UnicodeName: "E5.0 person in steamy room",
        CodePoint:   "1F9D6",
        Group:       "People & Body",
        SubGroup:    "person-activity",
    },
    {
        Slug:        "butterfly",
        Character:   "🦋",
        UnicodeName: "E3.0 butterfly",
        CodePoint:   "1F98B",
        Group:       "Animals & Nature",
        SubGroup:    "animal-bug",
    },
}

Get all

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

package main

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

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

Remove all emojis

The function removes all emojis from given string:

res := gomoji.RemoveEmojis("🧖 hello 🦋world")
println(res) // "hello world"

Get emoji info

The function returns info about provided emoji:

info, err := gomoji.GetInfo("1") // error: the string is not emoji
info, err := gomoji.GetInfo("1️⃣")
println(info)

Result:

gomoji.Entity{
    Slug:        "keycap-1",
    Character:   "1️⃣",
    UnicodeName: "E0.6 keycap: 1",
    CodePoint:   "0031 FE0F 20E3",
    Group:       "Symbols",
    SubGroup:    "keycap",
}

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"`
}

Example:

[]gomoji.Emoji{
    {
        Slug:        "butterfly",
        Character:   "🦋",
        UnicodeName: "E3.0 butterfly",
        CodePoint:   "1F98B",
        Group:       "Animals & Nature",
        SubGroup:    "animal-bug",
    },
    {
        Slug:        "roll-of-paper",
        Character:   "🧻",
        UnicodeName: "E11.0 roll of paper",
        CodePoint:   "1F9FB",
        Group:       "Objects",
        SubGroup:    "household",
    },
}
