💖 nix3-realisation-info(1) — NAME 💖

okay so, welcome to nix3-realisation-info(1), bestie — this page is straight from the General Commands Manual, and it's all about nix realisation info. 💅

⚠️ Warning: This program is experimental and its interface is subject to change. 💀

nix realisation info — query information about one or several realisations. That's the name section, periodt. ✨

🦋 SYNOPSIS 🦋

nix realisation info [option…] installables…

🌈 DESCRIPTION 🌈

Display some information about the given realisation. Short, sweet, iconic. 🍓

🎀 EXAMPLES 🎀

Show some information about the realisation of the hello package:

$ nix realisation info nixpkgs#hello --json
[{"id":"sha256:3d382378a00588e064ee30be96dd0fa7e7df7cf3fbcace85a0e7b7dada1eef25!out","outPath":"fd3m7xawvrqcg98kgz5hc2vk3x9q0lh7-hello"}]

✨ OPTIONS ✨

  • --json — Produce output in JSON format, suitable for consumption by another program. 🔥
  • --no-pretty — Print compact JSON output on a single line, even when the output is a terminal. Some commands may print multiple JSON objects on separate lines.

See --pretty. 👀

  • --pretty — Print multi-line, indented JSON output for readability.

Default: indent if output is to a terminal.

This option is only effective when --json is also specified. 🫶

  • --stdin — Read installables from the standard input. No default installable applied. 💌

🧪 Common evaluation options 🧪

  • --arg name expr — Pass the value expr as the argument name to Nix functions.
  • --arg-from-file name path — Pass the contents of file path as the argument name to Nix functions.
  • --arg-from-stdin name — Pass the contents of stdin as the argument name to Nix functions.
  • --argstr name string — Pass the string string as the argument name to Nix functions.
  • --debugger — Start an interactive environment if evaluation fails. 🛠️
  • --eval-store store-url — The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
  • --impure — Allow access to mutable paths and repositories.
  • --include / -I path — Add path to search path entries used to resolve lookup paths.

This option may be given multiple times.

Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable. 🌟

  • --override-flake original-ref resolved-ref — Override the flake registries, redirecting original-ref to resolved-ref.
  • --commit-lock-file — Commit changes to the flake’s lock file.
  • --inputs-from flake-url — Use the inputs of the specified flake as registry entries.
  • --no-registries — Don’t allow lookups in the flake registries.
DEPRECATED: Use --no-use-registries instead. 💀
  • --no-update-lock-file — Do not allow any updates to the flake’s lock file.
  • --no-write-lock-file — Do not write the flake’s newly generated lock file.
  • --output-lock-file flake-lock-path — Write the given lock file instead of flake.lock within the top-level flake.
  • --override-input input-path flake-url — Override a specific flake input (e.g. dwarffs/nixpkgs). The input path must not be empty. This implies --no-write-lock-file.
  • --recreate-lock-file — Recreate the flake’s lock file from scratch.
DEPRECATED: Use nix flake update instead. 💀
  • --reference-lock-file flake-lock-path — Read the given lock file instead of flake.lock within the top-level flake.
  • --update-input input-path — Update a specific flake input (ignoring its previous entry in the lock file).
DEPRECATED: Use nix flake update instead. 💀
  • --debug — Set the logging verbosity level to ‘debug’.
  • --log-format format — Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
  • --print-build-logs / -L — Print full build logs on standard error.
  • --quiet — Decrease the logging verbosity level. 🤫
  • --verbose / -v — Increase the logging verbosity level. 🗣️

🌸 Miscellaneous global options 🌸

  • --help — Show usage information.
  • --offline — Disable substituters and consider all previously downloaded files up-to-date.
  • --option name value — Set the Nix configuration setting name to value (overriding nix.conf).
  • --refresh — Consider all previously downloaded files out-of-date.
  • --repair — During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
  • --version — Show version information. 👑

🦋 Options that change the interpretation of installables 🦋

  • --all — Apply the operation to every store path.
  • --derivation — Operate on the store derivation rather than its outputs.
  • --expr expr — Interpret installables as attribute paths relative to the Nix expression expr.
  • --file / -f file — Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression is read from standard input. Implies --impure.
  • --recursive / -r — Apply operation to closure of the specified paths.
📝 Note: See man nix.conf for overriding configuration settings with command line flags.

That’s the whole page, bestie! The footer just says nix3-realisation-info(1) — no extra version/date line on this one, so that’s the vibe. 🫶✨
