A tiny commandline tool for parsing JSON from any source.

jp

Simply parse JSON from any input source.

Inspired by jq; not a replacement. Supports Lodash .get() path syntax and JSONPath syntax. Also supports stdin streaming (see last example), i.e. line-by-line.

yarn global add jp-cli || npm install -g jp-cli

Usage

Pipe jp onto a JSON source from the commandline to parse the output:
  cat data.json | jp [options] query

Options:
  -p, --path      Use JSON Path notation (https://github.com/dchester/jsonpath)
  -k, --keys      Print object keys only                               [boolean]
  -f, --file      Read input from file                                  [string]
  -i, --indent    Number of spaces for indentation (ignored by --human)
                                                           [number] [default: 2]
  -h, --human     Print human-readable (non-JSON) format               [boolean]
  -b, --break     Set break length of object/array for human format     [number]
  -c, --no-color  Disable color for human format                       [boolean]
  -d, --depth     Depth for human format                                [number]
  -L, --line-by-line  Parse each line as a separate input              [boolean]
  --help          Show help                                            [boolean]

Queries use the Lodash get method by default.

Examples

$ cat user-response.json | jp data.user

{
  "name": "Gazorpazorpfield",
  "color": "orange"
}

$ cat user-response.json | jp data.user | jp --keys

[
  "name",
  "color"
]

$ cat user-response.json | jp data.user.name

"Gazorpazorpfield"

jp can also parse JSON line-by-line from a stdin stream.

$ ipfs log tail | jp -L event | jq -r

Syntax error

@therealklanni
Hi, thanks for this package.

I tried to run version v2.0.1 and v2.0.0 and get the following error:

/usr/bin/jp: line 1: syntax error near unexpected token `('
/usr/bin/jp: line 1: `const _ = require(`lodash`)'

I think the problem is that

#!/usr/bin/env node

is missing at the beginning of the index.js file. Would have submitted a PR but I don' know how you would like to proceed beause I saw that in older versions you kept different files for the commandline file and the index.js file.

My node version is 6.10.3.
My npm version is 3.10.10.
