# jsontools

Handy command line tools for dealing with json data.

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

```zsh
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](https://github.com/ndjson/ndjson-spec) 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**:

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

- **is_json**:

```console
# 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**:

```console
# 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**:

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

- **pp_ndjson**:

```console
# 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
    ]
}
```
