Choose an item from a file or input stream using drand
npm install -g dchoose
Select some random entries from a file:
cat /some/path/to/file | dchoose --count 2
Or alternatively:
dchoose --count 2 --file /some/path/to/file
Flip a coin:
echo -e "heads\ntails" | dchoose
-c, --count
The number of items to select from the input. Default is 1.
-u, --drand-url
The drand URL to use. The default is quicknet (i.e. https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971)
-f, --file
The file to select items from. Each line is considered an entry. Alternatively, you can pass a file via stdin by using e.g. cat
-r, --randomness
Custom randomness with which to draw from instead of using the next drand round. Must be in hex format. This can be useful for verifying past draws or repeatability.
-v, --verbose
A verbose output format for when you want to know a little more about the draw, or want to repeat it.
The output format (prettified) looks something like:
{
"time": 1699439820012,
"round": 123456,
"randomness": "f73220684f2a171ffb00ec3b21983e01738bc863e26f374b0a76081416eebda8",
"totalCount": 2,
"winners": ["heads"]
