💖 DH_HASKE..._DEPENDS(1) 💖

okay so bestie, welcome to the Haskell devscripts documentation — this is the manual for dh_haskell_extra_depends, and honestly? it's giving quietly essential. 🎀

✨ NAME ✨

dh_haskell_extra_depends — the little guy that generates the extra-depends file in Haskell packages. 💅

🌸 SYNOPSIS 🌸

dh_extra_haskell_depends [debhelper options] [-Xpackage]
[--exclude=package] [file ...]

yes, the synopsis spells it dh_extra_haskell_depends while the NAME says dh_haskell_extra_depends. not me noticing that. it's canon, don't touch it. 🙈

🦋 DESCRIPTION 🦋

dh_haskell_extra_haskell_depends... okay no, it's dh_haskell_extra_depends, and it's a debhelper program that helps with calculating dependencies for building Haskell libraries. ✨

Here's the tea, and it's actually important: Haskell libraries are statically linked. Which means packagers who use Haskell libraries cannot just rely on the fact that dynamical libraries are dependencies of their packages to be sure that possible runtime data packages are installed at execution time. 😭 Like, that whole safety net? not there for you, bestie.

So the extra dependencies mechanism exists, and it lets libraries declare some packages that are to be added to the dependency list of each package that uses them to build. group project, but make it dependency metadata. 🫶

This script scans the Haskell dependencies and harvests extra dependencies information, putting them in the file debian/extra-depends, which is later used by dh_haskell_depends to be included in the substvars file. the pipeline is pipelining. 🔥

💀 BUGS 💀

None, as far as we know. :-)

fr fr, zero bugs, we are thriving, we are unbothered, we are iconic. 👑
