node -pthat accepts stdin and can format and highlight output
jstdin works really well in conjunction with lbl (a line-by-line stdin parser, sort of like AWK, but 100% JS)
$ npm install jstdin --global$ 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'
