CodeParser

Parse code using antlr.

• The lexer and parser classes in CodeParser are generated by Antlr grammar file.
• The CodeParser.Test demonstrates how to parse source code file to extract class and interface with their properties and methods. By now, the Java, C#, Python, PHP, JavaScript, C++, C language and MySql have been included.
• The CodeParser.Viewer is a visual tool to analyse the parser rules.

Example

1. Python

• source code

#!/usr/bin/python3
 
class HelloWorld():   
    owner = ""
    target = ""
    def sayHello(self, word):
        print(word)

x = HelloWorld() 

x.sayHello("Hello")

• parser test output

Class:HelloWorld
{
Field:owner
Field:target
Method:sayHello
}

2. PHP

• source code

<?
namespace demo;
use ArrayObject;

$count = 0;

class HelloWorld {
    public string $owner;
    public string $target;

	function sayHello(?string $word)
	{
	    echo $word;
	}
}

function test()
{
   $helloWorld = new HelloWorld();
   $helloWorld->sayHello();
}

?>

• parser test output

Namespace:demo
Use:ArrayObject
Field:$count
Class:HelloWorld
{
Field:$owner
Field:$target
Method:sayHello
}
Function:test
