jsontools

Handy command line tools for dealing with json data.

To use it, add jsontools to the plugins array in your zshrc file:

plugins=(... jsontools)

Requirements

The plugin uses one of these tools to process JSON data, in the following order:

• node
• python3
• ruby

Any of these must be in $PATH before the plugin is loaded, otherwise the plugin exits prematurely and the functions will not be available.

Usage

Usage is simple... just take your json data and pipe it into the appropriate jsontool:

• pp_json: pretty prints json.
• is_json: returns true if valid json; false otherwise.
• urlencode_json: returns a url encoded string for the given json.
• urldecode_json: returns decoded json for the given url encoded string.

Supports NDJSON (Newline Delimited JSON)

The plugin also supports NDJSON input, which means all functions have an alternative function that reads and processes the input line by line. These functions have the same name except using ndjson instead of json:

pp_ndjson, is_ndjson, urlencode_ndjson, urldecode_ndjson.

Examples

• pp_json:

# curl json data and pretty print the results
curl https://coderwall.com/bobwilliams.json | pp_json

• is_json:

# validate if file's content conforms to a valid JSON schema
$ is_json < data.json
true
# shows true / false and returns the proper exit code
$ echo $?
0

• urlencode_json:

# json data directly from the command line
$ echo '{"b":2, "a":1}' | urlencode_json
%7B%22b%22:2,%20%22a%22:1%7D

• urldecode_json:

# url encoded string to decode
$ echo '%7B%22b%22:2,%20%22a%22:1%7D' | urldecode_json
{"b":2, "a":1}

• pp_ndjson:

# echo two separate json objects and pretty print both
$ echo '{"a": "b"}\n{"c": [1,2,3]}' | pp_ndjson
{
    "a": "b"
}
{
    "c": [
        1,
        2,
        3
    ]
}
