Accessing a hash within a hash is very cumbersome as it requires many safeguards to be placed to avoid jku from crashing if an object doesn't exist. See this example

(_.connections && _.connections.length && _.connections.reduce(function(m, c){ return (c.scope == "burt.beacon" && (c.name == "customer_id_type_1" || c.name == "customer_id_type_2")) ? "logged-in" : m }, "") || "not-logged-in")

it would be nice if this could be written something like:

_.connections[?(@.scope=="burt.beacon" && @.name==/(customer_id_type_1|customer_id_type_2)/)] ? "logged-in" : "not-logged-in"

given that the program "decorate" exists, accepting 2 args - type of data to decorate and key, example being decorate day_of_week 1399248007040, it would ROCK if I could write the following:

jku -t '[_.timestamp, decorate(day_of_week, _.timestamp)]'

and get the output:

1399248007040\tMonday

if the shell command returns non-zero exit code, jku should abort

Hello mr. Bjorn.

It's not in my nature to ask other people for favors (unless sexual), but I'm too lazy in this case.

I would like an option that works similar to transformers. The option takes one or more arguments and will for each JSON line, only include attributes that are specified as arguments to the option. For example:

{"one": "lorem", "two": "ipsum",     "three": "dolor"}
{"one": "amet",  "two": "consequat", "three": "tortor"}
{"one": "quis",  "two": "fermentum", "three": "magna"}

Running this:

$ cat ABOVE-FILE | jku --some-option one three

Would produce this:

{"one": "lorem", "three": "dolor"}
{"one": "amet",  "three": "tortor"}
{"one": "quis",  "three": "magna"}

Could you please implement this for me sugar?
