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:

1{
2  "bool": true,
3  "short array": [
4    1,
5    2,
6    3
7  ],
8  "long array": [
9    {
10      "x": 1,
11      "y": 2
12    },
13    {
14      "x": 2,
15      "y": 1
16    },
17    {
18      "x": 1,
19      "y": 1
20    },
21    {
22      "x": 2,
23      "y": 2
24    }
25  ]
26}

into:

1{
2  "bool": true,
3  "short array": [1, 2, 3],
4  "long array": [
5    {"x": 1, "y": 2},
6    {"x": 2, "y": 1},
7    {"x": 1, "y": 1},
8    {"x": 2, "y": 2}
9  ]
10}

Installation

npm install json-spc

Usage

1cat 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:

1(define-format-all-formatter json-spc
2    (:executable "json-spc")
3    (:install "npm i -g json-spc")
4    (:languages "JSON")
5    (:features region)
6    (:format
7     (format-all--buffer-easy
8      executable
9      "--indent=3"
10      "--maxlength=100"
11      (when region
12        (list "--start" (number-to-string (1- (car region)))
13              "--end" (number-to-string (1- (cdr region))))))))
