How to add more to Git Bash on Windows

Git for Windows comes bundled with the "Git Bash" terminal which is incredibly handy for unix-like commands on a windows machine. It is missing a few standard linux utilities, but it is easy to add ones that have a windows binary available.

The basic idea is that C:\Program Files\Git\mingw64\ is your / directory according to Git Bash (note: depending on how you installed it, the directory might be different. from the start menu, right click on the Git Bash icon and open file location. It might be something like C:\Users\name\AppData\Local\Programs\Git, the mingw64 in this directory is your root. Find it by using pwd -W). If you go to that directory, you will find the typical linux root folder structure (bin, etc, lib and so on).

If you are missing a utility, such as wget, track down a binary for windows and copy the files to the corresponding directories. Sometimes the windows binary have funny prefixes, so

	#!/usr/bin/env python3
	# -- coding: utf-8 --

	# Recursively generate pretty print of arbitrary objects
	def generate_pprint(obj, level_indent=" ", max_depth=None, verbose_output=True,
	justify_output=True, prevent_loops=True, prevent_revisit=False,
	explore_objects=True, excluded_ids=[], visited_ids=[],
	path_ids=[], current_depth=0):
	"""Recursively generates pretty print of arbitrary objects.

	# Based on the solution here: https://stackoverflow.com/questions/44580644/subtract-mean-from-pyspark-dataframe

	# Function to normalise (standardise) PySpark dataframes
	def standardize_train_test_data(train_df, test_df, columns):
	'''
	Add normalised columns to the input dataframe.
	formula = [(X - mean) / std_dev]
	Inputs : training dataframe, list of column name strings to be normalised
	Returns : dataframe with new normalised columns, averages and std deviation dataframes

	Can load easier and more indepth with https://github.com/Hydroque/DDSLoader

	Because a lot of crappy, weird DDS file loader files were found online. The resources are actually VERY VERY limited.

	Written in C, can very easily port to C++ through casting mallocs (ensure your imports are correct), goto can be replaced.
