NAC3 is a major, backward-incompatible rewrite of the compiler for the ARTIQ physics experiment control and data acquisition system. It features greatly improved compilation speeds, a much better type system, and more predictable and transparent operation.
NAC3 has a modular design and its applicability reaches beyond ARTIQ. The nac3core
module does not contain anything specific to ARTIQ, and can be used in any project that requires compiling Python to machine code.
WARNING: NAC3 is currently experimental software and several important features are not implemented yet.
NAC3 is packaged using the Nix Flakes system. Install Nix 2.4+ and enable flakes by adding experimental-features = nix-command flakes
to nix.conf
(e.g. ~/.config/nix/nix.conf
).
After setting up Nix as above, use nix shell git+https://github.com/m-labs/artiq.git?ref=nac3
to get a shell with the NAC3 version of ARTIQ. See the examples
directory in ARTIQ (nac3
Git branch) for some samples of NAC3 kernel code.
Install MSYS2, and open "MSYS2 MinGW x64". Edit /etc/pacman.conf
to add:
[artiq]
SigLevel = Optional TrustAll
Server = https://lab.m-labs.hk/msys2
Then run the following commands:
pacman -Syu
pacman -S mingw-w64-x86_64-artiq
Install lld-msys2
manually:
wget https://nixbld.m-labs.hk/build/115527/download/1/ld.lld.exe
mv ld.lld.exe C:/msys64/mingw64/bin
Note: This build of NAC3 cannot be used with Anaconda Python nor the python.org binaries for Windows. Those Python versions are compiled with Visual Studio (MSVC) and their ABI is incompatible with the GNU ABI used in this build. We have no plans to support Visual Studio nor the MSVC ABI. If you need a MSVC build, please install the requisite bloated spyware from Microsoft and compile NAC3 yourself.

: Python abstract syntax tree definition (based on RustPython).nac3parser
: Python parser (based on RustPython).nac3core
: Core compiler library, containing type-checking and code generation.nac3standalone
: Standalone compiler tool (core language only).nac3artiq
: Integration with ARTIQ and implementation of ARTIQ-specific extensions to the core language.runkernel
: Simple program that runs compiled ARTIQ kernels on the host and displays RTIO operations. Useful for testing without hardware.
Use nix develop
in this repository to enter a development shell.
If you are using a different shell than bash you can use e.g. nix develop --command fish
.
Build NAC3 with cargo build --release
. See the demonstrations in nac3artiq
and nac3standalone
