Consume an iterable in chunks, skipping what's not needed. Similar to the "grouper" recipe in https://docs.python.org/2/library/itertools.html#recipes

	from itertools import islice

	test = []
	for batch in list(igrouper(range(24), 5)):
	test.append(list(batch))

kouk / How to add a submodule with shallow checkout and shallow clone

Last active April 17, 2024 20:16

.How to add a submodule with shallow checkout and shallow clone

	If you have a huge repository (in size and in history) and want to add a subfolder
	to your project as a submodule you can follow this example to save time and space
	using git's shallow clone and shallow checkout feature. It is a bit more complicated
	in this example because I assume that you want your submodule to track a non-default
	branch, called `mybranch`, instead of the `master` branch. Things could probably get
	a lot simpler when using the default branch. After following the commands in these
	examples you can use `git submodule update` and `git submodule update --remote` as normal.
