anyloop

Simple, extensible, plugin-based feedback loop software, with a primary focus on supporting adaptive optics applications.

For now, anyloop aims to support:

• Linux (though it may be compatible with other POSIX systems)
• x86-64 and AArch64
• GCC and Clang

Anyloop is subject to the terms of the Mozilla Public License, version 2.0. If a copy of the MPL was not distributed with this repository, you can obtain one at http://mozilla.org/MPL/2.0/.

Installing

You will need the following packages to compile and run anyloop from source:

• meson
• pkgconf
• json-c
• gsl

For example:

# archlinux (TODO: AUR package)
sudo pacman -S --asdeps meson pkgconf json-c gsl
# alpine
doas pkg add meson pkgconf json-c json-c-dev gsl gsl-dev
# raspbian
sudo apt install meson pkgconf libjson-c5 libjson-c-devel libgsl25 libgsl-devel

Once you have satisfied dependencies, build anyloop with meson:

meson setup build
meson compile -C build
sudo meson install -C build

Uninstalling

Soon, anyloop will at least be an AUR package so those using Archlinux can simply uninstall via pacman. If you installed with meson, manually wipe the /opt/anyloop directory and the binary at the path returned by which anyloop.

How it works

Inspired by multimedia frameworks like PipeWire and GStreamer, anyloop implements a pipeline. Unlike those more complex frameworks, anyloop is much simpler and more generic. Devices (elements of the pipeline) are arranged and processed linearly, each of them reading and writing to the data currently in the pipeline state.

See conf.md for documentation on how to configure anyloop's pipeline, and devices.md for information on how devices work.
