mokuton

Generates abstract syntax trees from function source code and then inserts it and the input types and output types back into MongoDB.

Dependencies: javalang, pymongo

Refer to https://docs.mongodb.com/getting-started/python/client/ for more info on pymongo

Note:

• All strings are returned as unicode
• javalang parser expects a syntactically correct class, so need a class template to place functions into.

Example:

Given 'public class HelloWorld{public static int findFirst(int value, int idx) { value &= ~((1 << idx) - 1); int result = Integer.numberOfTrailingZeros(value);        return (result == 32) ? -1 : result;}}'

Expanded (manually):
public class HelloWorld
{
	public static int findFirst(int value, int idx) 
	{
		value &= ~((1 << idx) - 1);
		int result = Integer.numberOfTrailingZeros(value);
		return (result == 32) ? -1 : result;
	}
}
