JSON Linter

Ruby is a beautiful programming language that was designed for programmer productivity. It comes feature-packed with numerous inbuilt classes and methods to make programming enjoyable for developers.

According to Wikipedia, JSON(JavaScript Object Notation) is an open standard file format and data interchange format. It uses human-readable text to store and transmit data objects. JSON files consist of attribute-value pairs and arrays (or other serializable values).

In today's development world, JSON is one of the popular data formats. Although it was derived from JavaScript, it a language-independent format. Many languages come with an inbuilt JSON parser. It is also a light-weight format and, it is human-readable.

This project aims to use some of Ruby's inbuilt methods to build a JSON linter. The project will continue to evolve and be updated. I hope you find it helpful.

Linter Description📄

This JSON linter checks for the following errors/warnings:

1. Check empty line error
2. Check for missing/unexpected tags i.e. '( )', '[ ]', and '{ }'
3. Check for the wrong indentation
4. Check for the malformed fractions
5. Check for the leading zeros
6. Check new line at end of JSON

Below you can see good, bad and empty JSON files and their test results on the console

Well formed JSON passes the test successfully!

# Well Formed JSON
{
  "firstName": "John",
  "lastName": "Snow",
  "age": 25,
  "children": [],
  "spouse": null,
  "address": {
    "street": "7504 Taylor Drive",
    "city": "New York City",
  },
  "phoneNumbers": [
    {
      "type": "mobile",
      "number": "212 555-3346"
    }
  ]
}

Console output

Badly formed JSON fails the test

# Badly formed JSON
{
  "openObject": {
  "improperIndent": "string 0"
    "leadingZero": {"example": 01},

    "unterminatedFraction": {"example": .1},
    "openObject": {
      "street": "7504 Taylor Drive",
      "city": "New York City",
      "state": "New York",
      "postalCode": "11238"
  ]

Console output

Empty JSON file shows a warning to the user!
