can you explain what is keys() and o. Are they predefined.

$ echo '{"name":{"first":"Jason"},"age":25}' | jawk '{
	keys(o); for (k in o) print k, _[o[k],JSON]
}'
name {"first":"Jason"}
age 25

Where can i find full documentation.

But this is amazing project. looking for something like this

How can i install in archlinux

This is the json file demo-blank-line.json content:

{
    "node_name" : "test_node",

    "log_valid_days" : 7
}

This is the jawk command line:
./jawk '{print _["log_valid_days"]}' demo-blank-line.json
and this is the command output:

demo-blank-line.json: expected <string> but got <EOF> (length 3) at input token 1
<<EOF>>

if I remove the blank line of demo-blank-line.json to make it look like this:

{
    "node_name" : "test_node",
    "log_valid_days" : 7
}

and run the same command line again, then it output:
7
My questions is:

1. Why command failed just because of one blank line difference?
2. Why need patch JSON.awk with patch-json-awk.diff?
3. How can I use jawk with blank line json file?
