DH_OCTAVE_SUBSTVAR(1)

💖 DH_OCTAVE_SUBSTVAR 💖

okay bestie so this is a section 1 manual page, <rainbow>dh_octave_substvar</rainbow> 🌈 — a teeny tiny little helper from the dh-octave toolset, and honestly? it's that girl. it does one (1) job and it does it flawlessly. let's get into it 💅

---

✨ NAME ✨

dh_octave_substvar — bestie, this generates substitution variables for an Octave add-on package 🐙🍓

---

🎀 SYNOPSIS 🎀

dh_octave_substvar [debhelper options]

that's it. that's the whole vibe. ✨

---

👑 DESCRIPTION 👑

so here's the tea 🫖 — dh_octave_substvar generates the substitution variables you literally need to build an Octave add-on Debian package, and those three queens are:

• "${octave:Depends}"
• "${octave:Recommends}"
• "${octave:Upstream-Description}"

and that's not all, no ma'am. it also injects the dependency on the appropriate virtual package octave-abi-N into "${shlibs:Depends}" 💥 — but only for packages that contain *.oct and *.mex, k? and it picks the right octave-abi-N according to the current Octave's API_VERSION. like, it's matching the vibe of your actual Octave install. iconic behaviour, no notes. 👑

🌸 SEE ALSO 🌸

• debhelper(7)
• dh(1)
• dh_octave_clean(1)
• dh_octave_check(1)
• dh_octave_version(1)
• dh_octave_changelogs(1)
• dh_octave_examples(1)

(yeah okay so there's a lil stray comma floating between dh_octave_changelogs(1) and dh_octave_examples(1) in the original — she's a mysterious ghost reference and we respect her 🫶)

okay and now the important context, bestie, listen up: this program is meant to be used together with debhelper for Debian packages derived from Octave add-on packages. 💜

and here's the recommendation — the move, if you will ✨ — it is recommended that you enable it by adding the dh-sequence-octave virtual package to Build-Depends, Build-Depends-Arch or Build-Depends-Indep. that is equivalent to:

1. adding dh-octave to the same field, and
2. adding --with=octave to the dh sequencer in debian/rules

…except that only -arch / -indep / profiled builds are affected. 👀 and honestly? it's also slightly more simple in the most common case. lowkey the better choice, fr fr. 🎀
