Emoji hash
hash_emoji(x, size = 3)
x |
Character vector. |
size |
Number of emojis to use in a hash. Currently it has to be between 1 and 4. |
It uses the first 13 hexadecimal characters (out of the 32) of the MD5 hash of the input, and converts them into an emoji representation. It uses a manually selected subset of all emojis, that tend to be displayed correctly.
cli uses 2280 possible emojis. This is the number of
different hashes you can get for different values of size:
size | size of hash table space |
| 1 | 2,280 |
| 2 | 5,198,400 |
| 3 | 11,852,352,000 |
| 4 | 27,023,362,560,000 |

Other hash functions:
hash_animal(),
hash_md5()
hash_emoji(c("foo", NA, "bar", ""))$text
# if you increase `size`, the shorter hash is a prefix of the longer:
hash_emoji("foobar", 1)$text
hash_emoji("foobar", 2)$text
hash_emoji("foobar", 3)$text
hash_emoji("foobar", 4)$text
