Emojisum

Build Status

๐Ÿ™ ๐Ÿ“Ž Emoji that checksum! ๐ŸŽ‰ ๐Ÿ’ฉ

A curated list of 256 emojis that are not entirely similar. Using http://www.webpagefx.com/tools/emoji-cheat-sheet/ and http://www.unicode.org/emoji/charts/full-emoji-list.html to compare them. With 256 as that is 8bit/1byte, and the hexadecimal output that is 2 hex characters.

So 2 hex positions are 1 emoji! Would you rather compare 60 hexadecimal characters or only 30 emoji?! ๐Ÿ˜บ

Specification

For information on the draft for broader practice, see the draft. Perma-URL:

Tool

build

go get github.com/emojisum/emojisum

usage

This uses github.com/kyokomi/emoji to print to the console, but also gives the string ouptut for easy pasting to github/markdown.

$> emojisum main.go 
SHA1(main.go)=  14b09535217ca8f5f47f4665e2266e686f0728b4
SHA1(main.go)=  :bird::red_car::on::crystal_ball::calendar::lemon::pray::warning::violin::lollipop::facepunch::hearts::tm::children_crossing::hourglass::heavy_plus_sign::house::ant::clap::rocket:

Like so!

pass in the checksums

Rather than relying on this simple tool to do the checksum itself, you will likely want to rely on OpenSSL or coreutils for checksumming. emojisum can just take those formats on stdin:

$> sha1sum main.go | emojisum -pg

Library

Use the golang library to access the mapped emoji words:

package main

import (
  "fmt"

  "github.com/emojisum/emojisum/emoji"
)

func main() {
  for i := 0; i < 255; i++ {
    fmt.Printf("%d (%2.2x):\n", i, i)
    for _, word := range emoji.Map(byte(i)) {
      fmt.Printf("  - %s\n", emoji.CodepointToUnicode(word))
    }
  }
}
