# emojisum
:pray: :paperclip: Emoji that checksum! :tada: :poop:
I attempted a curated list of 256 emojis that are not entirely similar. Using http://www.webpagefx.com/tools/emoji-cheat-sheet/ to compare them. I went with 256 as that is 8bit/1byte, and the hexadecimal output that is 2 hex characters.
So 1 emoji is 2 hex positions.
## build
```bash
go get github.com/vbatts/emojisum
```
## usage
This uses [`github.com/kyokomi/emoji`](https://github.com/kyokomi/emoji) to print to the console, but also gives the string ouptut for easy pasting to github/markdown.
```bash
$> 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:
SHA1(main.go)= 🐦 🚗 🔛 🔮 📆 🍋 🙏 ⚠️🎻 🍭 👊 ♥️™️🚸 ⌛️➕ 🏠 🐜 👏 🚀
```
Like so!
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:
### 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:
```bash
$> sha1sum main.go | emojisum -parse-coreutils
7656835947b4c6da272023c56b6f2529511bf88b main.go
:jp::gb::metal::goat::family::rocket::smiley_cat::swimmer::chocolate_bar::cactus::candy::smile::honeybee::house::cherries::cloud::fries::bow::wavy_dash::musical_score: main.go
🇯🇵 🇬🇧 🤘 🐐 👪 🚀 😺 🏊 🍫 🌵 🍬 😄 🐝 🏠 🍒 ☁️🍟 🙇 〰️ 🎼 main.go
```
Like so:
🇯🇵 🇬🇧 🤘 🐐 👪 🚀 😺 🏊 🍫 🌵 🍬 😄 🐝 🏠 🍒 ☁️🍟 🙇 〰️ 🎼 main.go
```bash
$> openssl sha1 main.go |emojisum -parse-openssl
SHA1(main.go)= 7656835947b4c6da272023c56b6f2529511bf88b
SHA1(main.go)= :jp::gb::metal::goat::family::rocket::smiley_cat::swimmer::chocolate_bar::cactus::candy::smile::honeybee::house::cherries::cloud::fries::bow::wavy_dash::musical_score:
SHA1(main.go)= 🇯🇵 🇬🇧 🤘 🐐 👪 🚀 😺 🏊 🍫 🌵 🍬 😄 🐝 🏠 🍒 ☁️🍟 🙇 〰️ 🎼
```
And like so:
