JSON To Unique

Parses the JSON document into a list of unique elements

Instructions

json2unique --help

usage: json2unique [-h] [-d DEPTH] [infile] [outfile]

JSON parser

positional arguments:
  infile                the path to the JSON file to be parsed
  outfile               the path to the output file

optional arguments:
  -h, --help            show this help message and exit
  -d DEPTH, --depth DEPTH
                        set maximum recursion depth

If the optional infile or outfile arguments are not passed to utility, STDIN and STDOUT will be considered as default values.

For large JSON files with many nested objects, you can manually increase the recursion depth using -d flag. The default value is 10_000.

Usage

Command Line Interface

You can use this package both as a CLI utility and as a library. Here is an example of how to use it in the terminal:

json2unique array.json

[1, 2, 42]

You can use Unix pipes to read STDIN and write to STDOUT streams:

echo '{"a": 1}' | json2unique > result.txt
cat result.txt 

[1, 'a']

Manually type the desired JSON in the terminal (press Ctrl+D when finish typing):

json2unique                    
{"a": [34, "hello", -343.56]}

['a', -343.56, 34, 'hello']

Use standard CLI Unix utilities to process the program's output:

json2unique array.json | grep 42

[1, 2, 42]

If there is a non-valid JSON, json2unique will throw an appropriate exception and terminate with a non-zero code:

echo '{"a": 1""}' | json2unique

Expecting ',' delimiter: line 1 column 8 (char 7)

Last exit code is:

echo $?

1

Python Library

To use this module as a library, enter the following line:

import json2unique

json2unique.parse_json_to_list_of_unique({"a": 1})  # [1, 'a']
