MPB-WHATREQUIRES(1)

💖 MPB-WHATREQUIRES(1) — the mpb-whatrequires manual, bestie edition 💖

okay so welcome to the mpb-whatrequires manual page, section 1 of the manual, and honestly? she's a baddie. let's get into it 🫶

---

✨ NAME ✨

mpb-whatrequires — bestie, she generates a list of reverse dependencies for the package names you hand her as input. that's the whole job. and she eats. 💅

---

🌸 SYNOPSIS 🌸

mpb-whatrequires [OPTION] package1 package2...

yes, that's it. options first, then a lil stack of package names. iconic behavior tbh.

---

🦋 DESCRIPTION 🦋

so here's the vibe: you give her a list of packages as input, and mpb-whatrequires will give you the latest version of those packages, and she may compute a list of packages that depend on them — either at build time or at runtime. both. she's versatile. ✨

this tool is the command line interface to the functions that are used by mpb(1) in order to compute reverse dependencies. so like, she's the front desk of a whole operation.

internally, she retrieves information using DNF and Koji APIs. no cap. that's where the tea comes from. 🍓

💅 OPTIONS 💅

okay this is the part everyone scrolls to, and for good reason. every single flag, right here, no skips:

• -h, --help — show the help message and exit. she'll tell you how to use her, then she dips. 👋
• --verbose, -V — increase output verbosity. and you can stack this one, multiple times, to modify the amount of information provided (e.g. -VV). the other options are affected by the verbosity level too, and they may provide different information depending on it. so more Vs = more lore. 🔥
• --version, -v — show the program version and exit. quick lil flex, then she's out. 👑
• --output, -o OUTPUT — where to store the list of packages. tell her where to drop the receipts. 📝
• --distrib DISTRIB — the distribution to be considered for the package repository. by default, mpb-whatrequires looks at Fedora Rawhide. that's her home turf fr fr. 🏠
• --releasever, -r RELEASEVER — the release version for the given distribution (e.g 36, rawhide ...). tell her which chapter of the story you're in.
• --arch, -a ARCH — the architecture to filter the packages for. heads up bestie: noarch packages are always included. by default, x86_64 packages are retrieved. no noarch erasure in this house. 🚫
• --depth, -d DEPTH — the dependency depth, i.e. for DEPTH=1, considering the following dependencies: D → C → B → A Then C and B are retrieved, when A is given as input. With DEPTH=2 then D would also be given. she goes as deep as you ask her to. respectfully. 😭
• --repo, r REPO — a custom dnf configuration in a special format, see mpb.config(5) for more details on how to write this configuration file. this may be used in order to provide repositories information on top of the built-in ones, or in order to overwrite them with different values.
  • a use case is for example to fake Rawhide repositories with ELN ones, so that a reduced set of package corresponding to the ones available in ELN is built in a rawhide environment. fake it till you make it energy. 🎀
• --no-deps — retrieve last build info for the given packages, but don't compute the dependency list. sometimes you just want the facts, not the whole family tree. 🙈
• --no-build-order — when computing the dependency list, disable build order calculation. she'll still give you the list, just not the order. lowkey chaotic, highkey valid.
