nix3-registry-add(1) General Commands Manual nix3-registry-add(1) Warning This program is experimental <../../development/experimental- features.md#xp-feature-nix-command> and its interface is subject to change. Name nix registry add - add/replace flake in user flake registry Synopsis nix registry add [option...] from-url to-url Examples • Set the nixpkgs flake identifier to a specific branch of Nixpkgs: # nix registry add nixpkgs github:NixOS/nixpkgs/nixos-20.03 • Pin nixpkgs to a specific revision: # nix registry add nixpkgs github:NixOS/nixpkgs/925b70cd964ceaedee26fde9b19cc4c4f081196a • Add an entry that redirects a specific branch of nixpkgs to another fork: # nix registry add nixpkgs/nixos-20.03 ~/Dev/nixpkgs • Add nixpkgs pointing to github:nixos/nixpkgs to your custom flake registry: nix registry add --registry ./custom-flake-registry.json nixpkgs github:nixos/nixpkgs Description This command adds an entry to the user registry that maps flake refer- ence from-url to flake reference to-url. If an entry for from-url al- ready exists, it is overwritten. Entries can be removed using nix registry remove <./nix3-registry-re- move.md>. Options • --registry <#opt-registry> registry The registry to operate on. Common evaluation options • --arg <#opt-arg> name expr Pass the value expr as the argument name to Nix functions. • --arg-from-file <#opt-arg-from-file> name path Pass the contents of file path as the argument name to Nix func- tions. • --arg-from-stdin <#opt-arg-from-stdin> name Pass the contents of stdin as the argument name to Nix functions. • --argstr <#opt-argstr> name string Pass the string string as the argument name to Nix functions. • --eval-store <#opt-eval-store> store-url The URL of the Nix store <../../store/types/index.md#store-url- format> to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them. • --impure <#opt-impure> Allow access to mutable paths and repositories. • --include <#opt-include> / -I path Add path to search path entries used to resolve lookup paths <../../language/constructs/lookup-path.md> This option may be given multiple times. Paths added through -I take precedence over the nix-path configura- tion setting <../../command-ref/conf-file.md#conf-nix-path> and the NIX_PATH environment variable <../../command-ref/env-common.md#env- NIX_PATH>. • --override-flake <#opt-override-flake> original-ref resolved-ref Override the flake registries, redirecting original-ref to resolved- ref. Logging-related options • --debug <#opt-debug> Set the logging verbosity level to `debug'. • --log-format <#opt-log-format> format Set the format of log output; one of raw, internal-json, bar or bar- with-logs. • --print-build-logs <#opt-print-build-logs> / -L Print full build logs on standard error. • --quiet <#opt-quiet> Decrease the logging verbosity level. • --verbose <#opt-verbose> / -v Increase the logging verbosity level. Miscellaneous global options • --help <#opt-help> Show usage information. • --offline <#opt-offline> Disable substituters and consider all previously downloaded files up-to-date. • --option <#opt-option> name value Set the Nix configuration setting name to value (overriding nix.conf). • --refresh <#opt-refresh> Consider all previously downloaded files out-of-date. • --repair <#opt-repair> During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths. • --version <#opt-version> Show version information. Note See man nix.conf <../../command-ref/conf-file.md#command-line-flags> for overriding configuration settings with command line flags. nix3-registry-add(1)
