jstdin
a better
node -p
that accepts stdin and can format and highlight output
FYI
jstdin
works really well in conjunction with lbl
(a line-by-line stdin parser, sort of like AWK, but 100% JS)
Installation
$ npm install jstdin --global
Usage
$ jstdin --help Usage: $ jstdin [code] [options] Description: executes javascript on the command line like `node -p` but also accepts data via stdin so long as [code] is wrapped with an anonymous function; it also formats output. Options: -r, --raw prevent formatting output -h, --help show this usage information Examples: # eval and print js (like node -p) $ jstdin '2*2' 4 # use stdin, process and pretty print $ echo '[1,2,3]' | jstdin 'x => x.map(x => x*2)' [ 2, 4, 6 ] # use stdin, process and do not pretty print $ echo '[1,2,3]' | jstdin 'x => x.map(x => x*2)' --raw [2,4,6] # use stdin and just pretty print $ echo '[{"n":1,"a":{"b":"c"}},{"n":2,"a":{"d":{"e":"f"}}}]' | jstdin' [ { "n": 1, "a": { "b": "c" } }, { "n": 2, "a": { "d": "e" } } ]
