Alternative to jq CLI tool using LiveScript

jqlsc.ls

#!/usr/local/bin/lsc -d

# example: echo "[1,2,3,4,5]" | ./jqlsc.ls "sum . map (+ 2)"

{each, obj-to-pairs} = require \prelude-ls
lsc = require \LiveScript

global <<< require \prelude-ls

trim = -> if it[*-1] == \; then it.substr 0, it.length - 1 else it

stdin = process.openStdin!
code = process.argv.2

input = ""
stdin.on \data, (data) -> 
	input += data if data is not null

stdin.on \end, ->
	compiled =  lsc.compile code, bare: true
	compiled = "(#{trim compiled})(#input)"
	process.stdout.write <| eval compiled |> (-> JSON.stringify it, null, 4)  |> (+ \\n)

You could simply import everything from prelude-ls to global scope like this:

global <<< require \prelude-ls

Color output:

| underscore print --color

| pygmentize -l javascript

| pjson
