These are some suggested changes to the new documentation of Haskell in
the Nixpkgs manual. They cover sections until, but excluding, the
section "Available package versions". I am not an English native
speaker, so please correct me and savage these changes!
Also, please let me know if the suggestions are welcome, then I will
continue with the next chapter.
This restarts a Haskell section in the nixpkgs manual. The content
presented here has been written from scratch, although some parts of it
take inspiration from the existing haskell4nix documentation.
It is by no means complete, the idea is mostly to get the ball rolling
in some way. Upcoming tasks are hinted at in the comments in the
documentation file.
Presenting an example with a patch (without even providing that patch!) is not ideal. Since `npm pack` now obeys `--ignore-scripts`, we can use that instead.
Avoids confusion: `vim-full`'s build-time features are configurable, but both
`vim` and `vim-full` are *customizable* (in the sense of user configuration).
The nixpkgs manual contains references to both sri hash and explicit
sha256 attributes. This is at best confusing to new users. Since the
final destination is exclusive use of sri hashes, see nixos/rfcs#131,
might as well push new users in that direction gently.
Notable exceptions to sri hash support are builtins.fetchTarball,
cataclysm-dda, coq, dockerTools.pullimage, elixir.override, and
fetchCrate. None, other than builtins.fetchTarball, are fundamentally
incompatible, but all currently accept explicit sha256 attributes as
input. Because adding backwards compatibility is out of scope for this
change, they have been left intact, but migration to sri format has been
made for any using old hash formats.
All hashes have been manually tested to be accurate, and updates were
only made for missing upstream artefacts or bugs.
Previously we had an assert that would complain when nugetDeps wasnt set,
which also didnt allow any passthru attributes (like fetch-deps) to be
build. That causes a cycle where you need nugetDeps to fetch the nuget
deps, but arent able to build the script to do so.
