json-spc

A CLI wrapper around the json-stringify-pretty-compact library.

Thanks and acknowledgements to Simon Lydell for creating this wonderful library.

Turns ugly JSON like:

{
  "bool": true,
  "short array": [
    1,
    2,
    3
  ],
  "long array": [
    {
      "x": 1,
      "y": 2
    },
    {
      "x": 2,
      "y": 1
    },
    {
      "x": 1,
      "y": 1
    },
    {
      "x": 2,
      "y": 2
    }
  ]
}

into:

{
  "bool": true,
  "short array": [1, 2, 3],
  "long array": [
    {"x": 1, "y": 2},
    {"x": 2, "y": 1},
    {"x": 1, "y": 1},
    {"x": 2, "y": 2}
  ]
}

Installation

npm install json-spc

Usage

cat file.json | json-spc [--indent=<spaces>] [--max-length=<characters>] [--start=<int> --end=<int>]

Options

• indent: Defaults to 2. Works exactly like the third parameter of JSON.stringify.
• maxlength: Defaults to 120. Lines will be tried to be kept at maximum this many characters long.
• start: format portion of stdin starting at position, if start and end provided
• end: format portion of stdin ending at position, if start and end provided

Usage with format-all-buffer.el

format-all Emacs package allows providing custom formatters. This fork of json-stringify-pretty-compact-cli exists to support format-all, namely M-x format-all-buffer and M-x format-all-region commands.

This is how to configure json-spc formatter:

(define-format-all-formatter json-spc
    (:executable "json-spc")
    (:install "npm i -g json-spc")
    (:languages "JSON")
    (:features region)
    (:format
     (format-all--buffer-easy
      executable
      "--indent=3"
      "--maxlength=100"
      (when region
        (list "--start" (number-to-string (1- (car region)))
              "--end" (number-to-string (1- (cdr region))))))))
