Installation

With Composer, to include this library into your dependencies, you need to require hoa/json:

$ composer require hoa/json '~2.0'

For more installation procedures, please read the Source page.

Testing

Before running the json suites, the development dependencies must be installed:

$ composer install

Then, to run all the test suites:

$ vendor/bin/hoa test:run

For more information, please read the contributor guide.

Quick usage

As a quick overview, we will see how to use the grammar to parse JSON strings.

Parse JSON strings

All we have to do is to use the Hoa\Compiler library. For instance, in CLI:

$ echo '{"foo": 42, "bar": [1, [2, [3, 5], 8], 13]}' | hoa compiler:pp hoa://Library/Json/Grammar.pp 0 -v dump
>  #object
>  >  #pair
>  >  >  token(string:string, foo)
>  >  >  token(number, 42)
>  >  #pair
>  >  >  token(string:string, bar)
>  >  >  #array
>  >  >  >  token(number, 1)
>  >  >  >  #array
>  >  >  >  >  token(number, 2)
>  >  >  >  >  #array
>  >  >  >  >  >  token(number, 3)
>  >  >  >  >  >  token(number, 5)
>  >  >  >  >  token(number, 8)
>  >  >  >  token(number, 13)
