buildDunePackage: add support function and use it in a few packages #49684

I can certainly backtrack of the src refactoring but I would find this pretty sad given that virtually all the dune packages that I refactored took their sources from GitHub. Furthermore, this setup makes it simpler for package maintainers to use the dune-release tarball if it is available (just set |
|
There could be a new fetcher for dune release tarballs. |
|
OK let's postpone this part then. |
|
@Mic92 I still do not know what you meant by "build hook" but the composability aspect might not be so important given how similar all dune packages are (and anyways, the current setup allows to override any given phase). |
|
OMG, this is horrible 😱 Don't count on me to imitate that 😉 |
|
Updated. This makes it a quite smaller refactoring (although I have updated even more packages). |
|
Where are these hooks coming from? Where is this documented? How is it different from |
|
Build phases are described in the stdenv documentation: https://nixos.org/nixpkgs/manual/#sec-stdenv-phases . It is not different from |
|
OK, I knew about this part of the doc but I had missed that this had to be run from the build phases themselves. Will update. |
|
Refactoring complete. Doc remains. |

The PR is ready now, and it includes the doc. It was quite time that OCaml got its section in the nixpkgs manual! |

In future this could be solved with the following trick:
fetchDuneRelease {
url = "https://github.com/flowtype/ocaml-wtf8/releases/download/v${version}/ocaml-wtf8-${version}.tbz";
sha256 = "1msg3vycd3k8qqj61sc23qks541cxpb97vrnrvrhjnqxsqnh6ygq";
};
fetchDuneRelease = { url, ... } @args : fetchurl (args // {
url = "${url}#package.tar.bz2";
})
This would do the trick in the unpack phase.

An alternative would be override the unpack phase of buildDunePackage to also learn this extension.

Agreed but voluntarily left for future work.

CI had passed but an update to odoc meant that I had to rebase the PR and fix the conflicts. Can this PR get merged now? I would like to avoid having to rebase it once more. |

I built all affected packages on Linux. Are there problems on other architectures? |

This might have been not included in the list as ocamlPackages are not recursed. $ nix-shell -p acgtk -p eff -p flow -p fstar -p google-drive-ocamlfuse -p jackline -p libbap -p liquidsoap -p ocaml-top -p ocamlformat -p patdiff -p pyre -p reason -p satysfi -p stog -p trv -p virt-top |

I don't see why this should be harder to fix then before. |

@vbgl Can you explain how this makes it harder to fix? The goal of this PR was to make the life of contributors (I included) easier not harder. |

Motivation for this change
This takes advantage of the uniformization of the OCaml package ecosystem around the dune build system (and often the accompanying dune-release) to simplify the way usual OCaml derivations are prepared in nixpkgs.
