💖 nix3-store...-hash-part(1) 💖

okay bestie, grab your matcha because we're diving into the General Commands Manual and this one is a lil cutie. it's nix store path-from-hash-part, and yes the title is giving "why are there dots" but it's iconic, trust. 🎀

⚠️ Warning — this program is experimental and its interface is subject to change. so like, don't build your whole personality on it, okay? 🙈

✨ Name ✨

nix store path-from-hash-part — get a store path from its hash part 🦋

lowkey that's the whole job. she does one thing and she does it well.

🌸 Synopsis 🌸

nix store path-from-hash-part [option…] hash-part

🍓 Examples 🍓

  • Return the full store path with the given hash part:
# nix store path-from-hash-part --store https://cache.nixos.org/ qbhyj3blxpw2i6pb7c6grc9185nbnpvy
/nix/store/qbhyj3blxpw2i6pb7c6grc9185nbnpvy-hello-2.10

not her turning 32 little characters into a whole entire path, main character energy fr fr 👑

💜 Description 💜

so here's the vibe: you hand her the hash part of a store path — that's the 32 characters that come right after /nix/store/ — and she hands you back the full store path. glow-up complete. ✨

where does this actually matter? it's primarily useful in the implementation of binary caches, because when something asks for a .narinfo file, the request only supplies the hash part. like this:

https://cache.nixos.org/qbhyj3blxpw2i6pb7c6grc9185nbnpvy.narinfo

see? just the hash part, no path, no vibe check. that's her moment. 🫶

🎀 Options 🎀

  • --debug — set the logging verbosity level to ‘debug’. she's telling you everything, no secrets, we love an over-sharer. 💅
  • --log-format format — set the format of log output; one of raw, internal-json, bar or bar-with-logs. pick your aesthetic bestie. 🌈
  • --print-build-logs, -L — print full build logs on standard error.
  • --quiet — decrease the logging verbosity level. shhh. 🤫
  • --verbose, -v — increase the logging verbosity level. louder!! 📢

Miscellaneous global options

  • --help — show usage information. when in doubt, ask her directly. 💖
  • --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  • --refresh — consider all previously downloaded files out-of-date.
  • --version — show version information.
📝 Note — see man nix.conf for overriding configuration settings with command line flags. iykyk. 🧚

and that's the whole page bestie, we ate and left absolutely no crumbs. 🍓✨ this came from the General Commands Manual, page nix3-store...-hash-part(1) — no cap, go forth and resolve those hash parts. bye pookie, slay responsibly 💜👑
