graphql-parser

PHP Extension for Parsing GraphQL Query Language and GraphQL Schema Language. Based off Facebooks own C parser implemention.

Requirements

• PHP 7+ (brew install php70 or brew install php71)
• libgraphqlparser (brew install libgraphqlparser)
• PHP-CPP

Installation

# modify INI_DIR in Makefile to be the path to your conf.d can be found using php-config --configure-options
make
make install

Usage

<?php
use AndHeiberg\GraphQL\Parser\Parser;
$parser = new Parser();
try {
    $ast = $parser->parse('query { name }');
} catch (\Exception $e) {
    echo sprintf('Parse error: %s', $e->getMessage());
}

Parser::parse() will be a AndHeiberg\GraphQL\Parser\AST\Document or a AndHeiberg\GraphQL\Parser\AST\SchemaDefinition object. Have a look at the php stub files to get an understanding of the AST structure.

The files can also be dropped into your IDE to allow auto-complete.

TODO:

• Remove modify INI_DIR step from installation
• Use custom exceptions instead of \Exception
• Generate PHP classes in the extension and convert the AST to PHP classes instead of array
• Generate PHP stubs for AST that can be used by IDEs
• Create build script to fetch latest ast.ast from libgraphqlparser
