A straightforward, nimble ECS for Python.
snecs
is a pure Python 3.6+, dependency-free
ECS library,
heavily inspired by Rust’s
Legion, and aiming to be as
fast and easy-to-use as possible.

snecs
is an
ECS library,
written from the ground up to be:
The snecs
API is designed to be both easy-to-use, and encourage cleanly
structured code. It follows a simple principle - functions do things,
classes represent things - in an attempt to reduce the incidence of
antipatterns like
ClassesAsNamespaces.
snecs
is written with a benchmark-driven approach. Every statement in
the hot path is benchmarked against alternative ways to express the same
behavior, to let your code run as fast as you need it to.
One of the design goals is outrunning esper, and eventually I’ll have a benchmark suite to post here.
snecs
has no dependencies
whatsoever,
other than Python 3.6 or higher; you won’t need to worry about
deprecation warnings from dependencies, or having to install systemwide
libraries for dependencies to work - because there are none! Installing
snecs is as simple as running:
$ pip install snecs
snecs
is written entirely in Python. It does not use any modules written
in C or any other language, which means that you don’t have to worry
about needing a C compiler if there are no wheels for your platform and
distribution, and that it works perfectly under PyPy, and gets the
full benefit of its JIT compiler and optimizations.
snecs
is checked against a very aggressive mypy
configuration
to catch bugs and let you fully enjoy the library even when writing
type-annotated code. You won’t have to # type: ignore
any use of
snecs.
Over a third of the non-blank lines in the snecs/
directory are
comments. If you ever need to dive into the code to see how snecs
works
under the hood, they will guide you through the source and explain every
workaround, optimization, and obscure trick you might find non-obvious.
