nickelpro / Python Enum
Created November 13, 2012 19:18
Do-It-Yourself Enumeration in Python
class enum(object):
def __init__(self, *names):
for number, name in enumerate(names):
setattr(self, name, number)
Example:
Month = enum(
"January",
"Febuary",

nickelpro / to_hex.cpp
Last active December 15, 2015 01:29
Creates a std::string of hex from data, data being basically any primitive data type. I have no idea under what conditions this will explode, probably many
#include <iomanip>
#include <sstream>
std::string to_hex(const void *data, const unsigned int size) {
std::stringstream stream;
stream << std::uppercase << std::hex;
const unsigned char *bytes = static_cast<const unsigned char *>(data);
for (unsigned int i = 0; i<size; ++i) {
stream << std::setfill('0') << std::setw(2) << static_cast<const int>(bytes[i]) << " ";
}

nickelpro / randpng.py
Created April 23, 2013 07:24
Generates a reasonably random PNG image, relies on pypng
import png
import random
random.seed()
pixels = [[random.randint(0, 255) for i in xrange(0, 3*64)] for i in xrange(0, 32)]
png.from_array(pixels, 'RGB').save('foo.png')

nickelpro / yggdrasil.py
Created October 16, 2013 21:51
Yggdrasil Authentication implementation for Minecraft, implements all known Yggdrasil methods and is a lot simpler than some of the other implementations floating around
import urllib.request as request
from urllib.error import HTTPError
import json
class YggAuth:
def __init__(self,
client_token=None,
access_token=None,
username=None,
password=None

nickelpro / mcvarint.py
Created November 5, 2013 02:20
Two python functions that implement the new Minecraft varint type (32-bit signed integers packed into Google protobuf varints). Packs varints into a byte string, unpacks varints from a buffer that has a read(bytes) method. Supports negative numbers even though they aren't used in the current protocol.
import struct
def pack_varint(val):
total = b''
if val < 0:
val = (1<<32)+val
while val>=0x80:
bits = val&0x7F
val >>= 7
total += struct.pack('B', (0x80|bits))
