this aspect of golang modules is a mess. You can not have a top-level
`package main` that has its own go.mod, and then also export a
sub-directory that has its own go.mod for cleaner dependency imports by
outside importers.
So by removing this, you're subject to the top-level go.mod of the
project. Otherwise the top-level main.go needs to be moved to a nested
./cmd/emojisum/ directory, which is a break for any packagers. 😵

Emojisum
🙏 📎 Emoji that checksum! 🎉 💩
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?! 😺
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

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
7656835947b4c6da272023c56b6f2529511bf88b main.go

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))
}
}
}
