Ohh, huh, interesting. Yeah, it confuses me too. Would be interesting to see how one could find it. Cant find any way to see a list of the devel packages online... 🤔 cc.

I'm still pasting code around like a barbarian, but to do this properly, I'd follow these instructions, then cargo-cult their opam file and maybe understand it:
gitlab.mpi-sws.org/FP/iris-exampl
Coq-iris doesn't seem to depend on autosubst, but that code does, through a separate opam repo.

Ahh yes, seems to be on their repository: gitlab.mpi-sws.org/FP/opam-dev/tr

We were confused is because it requires you to mutate your opam environment:
opam repo add coq-released coq.inria.fr/opam/released
opam repo add iris-dev gitlab.mpi-sws.org/FP/opam-dev.git
find opam abit ick from a 'repoducable environment' perspective, but maybe I just don't understand...

Honestly... I have had some not great experiences with it. I think 2.0 is coming out soon though and that is supposed to resolve some pervasive issues.

Cool, that is good to hear! The CLI is pretty at least, with nice coloured unicode icons and little camels! Even as I recoil in horror as it seems to turn off and on packages globally.

I've had some really bad issues... e.g. the default solver taking 50 GB of RAM and hanging because there were a lot of minor versions published for the iris development package. Also, it can't seem to handle multiple versions of a package on the same machine at the same time...

You too might be interested in opam switch then, it's a bit like virtualenv! That even lets you install multiple coq versions! ssr.msr-inria.inria.fr/~gares/www/des
It's not perfect but after old Cabal I'll conform to anything.

Yeah, I really should use it... I think I mostly haven't because our build scripts don't, and I'm not sure why that is (IIRC it's hard to automate or something? Or was?).
2
To automate this, I fear you'll need a `prepare-profiles.sh` and a build script relying on those envs. Plus pain when prepare-profiles.sh changes, unless you can detect which build profiles exist (which you probably can?)...
I'd prefer this to what you describe but YMMV!

I am now scared and want to run away to Lean again... but yes, I want to run this stuff on CI and this would be neccessary. And I hate dev config being in READMEs 🤦♂️
yikes wait, does ``eval `opam config env` `` mutate your shell state?
1
Probably... not sure why else eval would be used here.
