-*- mode: org -*- [[https://www.gnu.org/software/guix/][GNU Guix]] (IPA: /ɡiːks/) is a purely functional package manager, and associated free software distribution, for the [[https://www.gnu.org/gnu/gnu.html][GNU system]]. In addition to standard package management features, Guix supports transactional upgrades and roll-backs, unprivileged package management, per-user profiles, and garbage collection. It provides [[https://www.gnu.org/software/guile/][Guile]] Scheme APIs, including a high-level embedded domain-specific languages (EDSLs) to describe how packages are to be built and composed. GNU Guix can be used on top of an already-installed GNU/Linux distribution, or it can be used standalone (we call that “Guix System”). Guix is based on the [[https://nixos.org/nix/][Nix]] package manager. * Requirements If you are building Guix from source, please see the manual for build instructions and requirements, either by running: info -f doc/guix.info "Requirements" or by checking the [[https://guix.gnu.org/manual/en/html_node/Requirements.html][web copy of the manual]]. * Installation See the manual for the installation instructions, either by running info -f doc/guix.info "Installation" or by checking the [[https://guix.gnu.org/manual/en/html_node/Installation.html][web copy of the manual]]. * Building from Git For information on building Guix from a Git checkout, please see the relevant section in the manual, either by running info -f doc/guix.info "Building from Git" or by checking the [[https://guix.gnu.org/manual/en/html_node/Building-from-Git.html][web_copy of the manual]]. * How It Works Guix does the high-level preparation of a /derivation/. A derivation is the promise of a build; it is stored as a text file under =/gnu/store/xxx.drv=. The (guix derivations) module provides the `derivation' primitive, as well as higher-level wrappers such as `build-expression->derivation'. Guix does remote procedure calls (RPCs) to the build daemon (the =guix-daemon= command), which in turn performs builds and accesses to the store on its behalf. The RPCs are implemented in the (guix store) module. * Contact GNU Guix is hosted at https://savannah.gnu.org/projects/guix/.

Join #guix on irc.libera.chat. * Guix & Nix GNU Guix is based on [[https://nixos.org/nix/][the Nix package manager]]. It implements the same package deployment paradigm, and in fact it reuses some of its code. Yet, different engineering decisions were made for Guix, as described below. Nix is really two things: a package build tool, implemented by a library and daemon, and a special-purpose programming language. GNU Guix relies on the former, but uses Scheme as a replacement for the latter. Using Scheme instead of a specific language allows us to get all the features and tooling that come with Guile (compiler, debugger, REPL, Unicode, libraries, etc.) And it means that we have a general-purpose language, on top of which we can have embedded domain-specific languages (EDSLs), such as the one used to define packages. This broadens what can be done in package recipes themselves, and what can be done around them. Technically, Guix makes remote procedure calls to the ‘nix-worker’ daemon to perform operations on the store. At the lowest level, Nix “derivations” represent promises of a build, stored in ‘.drv’ files in the store. Guix produces such derivations, which are then interpreted by the daemon to perform the build. Thus, Guix derivations can use derivations produced by Nix (and vice versa). With Nix and the [[https://nixos.org/nixpkgs][Nixpkgs]] distribution, package composition happens at the Nix language level, but builders are usually written in Bash. Conversely, Guix encourages the use of Scheme for both package composition and builders. Likewise, the core functionality of Nix is written in C++ and Perl; Guix relies on some of the original C++ code, but exposes all the API as Scheme. * Related software - [[https://nixos.org][Nix, Nixpkgs, and NixOS]], functional package manager and associated software distribution, are the inspiration of Guix - [[https://www.gnu.org/software/stow/][GNU Stow]] builds around the idea of one directory per prefix, and a symlink tree to create user environments - [[https://www.pvv.ntnu.no/~arnej/store/storedoc_6.html][STORE]] shares the same idea - [[https://live.gnome.org/OSTree/][GNOME's OSTree]] allows bootable system images to be built from a specified set of packages - The [[https://www.gnu.org/s/gsrc/][GNU Source Release Collection]] (GSRC) is a user-land software distribution; unlike Guix, it relies on core tools available on the host system aints will be reviewed and investigated promptly and fairly. All community leaders are obligated to respect the privacy and security of the reporter of any incident. Enforcement Guidelines Community leaders will follow these Community Impact Guidelines in determining the consequences for any action they deem in violation of this Code of Conduct: 1. Correction Community Impact: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community. Consequence: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested. 2. Warning Community Impact: A violation through a single incident or series of actions. Consequence: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban. 3. Temporary Ban Community Impact: A serious violation of community standards, including sustained inappropriate behavior. Consequence: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban. 4. Permanent Ban Community Impact: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. Consequence: A permanent ban from any sort of public interaction within the community.
