Composable CLI

[surprisetalk]

It would be cool if we could have a composable CLI that uses STDIN instead of filenames:

scrap eval < a.scrap

cat a.scrap | scrap eval

scrap eval <<< '1 + 2'

scrap eval <(echo "1 + 2")

I think this pattern shines when we include other commands:

cat users.scrap | scrap pipe "list/map (user -> user.name)"

cat a.scrap | scrap format > a.scrap

curl $SERVER/a | scrap flat parse | scrap type

cat a.scrap | scrap eval | scrap yard push
