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.
Closes#16182
This improves the error message
Error: _assignFirst found no valid variant!
which occurred when the set of outputs was not sufficient to set
the various outputDev, outputBin, etc variables. Specifically, this
would mean that "out" is not among the outputs, which is valid for
a derivation.
This changes the message to something like
error: _assignFirst: could not find a non-empty variable to assign to outputDev. The following variables were all unset or empty: dev out.
If you did not define an "out" output, make sure to define all the specific required outputs: define an output for one of the unset variables.
While this isn't a full explanation of what stdenv can and can not do,
I think it's vast improvement over the 0 bits of information that it
used to provide. This at least gives a clue as to what's going on, and
even suggests a fix, although probably multiple such fixes are required
in an instance where someone starts with a no-out derivation from scratch
(and decide to persist).
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.
matching on only `{...}` does not trigger if the role tag is preceded by
something usually considered a semantic separator that isn't a separator
as markdown knows it, e.g. punctuation characters.
The thunderbird derivation is using `buildMozillaMach` these days,
shared with Firefox and Librefox, so it is probably the correct
, although more complicated, successor.
This is preferable because it prevents things like disk corruption (requiring the user to delete the disk image when starting up) that I consistently ran into.
Move the manpage-to-URL mapping to `doc/manpage-urls.json` so that we can
reuse that file elsewhere, and generate the `link-manpages.lua` filter from
that file.
Also modify the Pandoc filter so that it doesn't wrap manpages that are
already inside a link.
Keeping a Lua filter is essential for speed: a Python filter would
increase the runtime `md-to-db.sh` from ~20s to ~30s (but Python is not
to blame; marshalling Pandoc types to and from JSON is a costly operation).
Parsing in Lua seems tedious, so I went with the Nix way.
The new derivation should evaluate only if the old derivation does.
Sadly this means that the old derivation cannot depend on the new one
any more, which was used by xorgserver on Darwin. But this is not a
problem as `overrideAttrs` can (and should) usually be used instead.
This change allowed catching an invalid `meta.platforms` in the linux_rpi
kernels, which use `overrideDerivation`.
The trailing `'` was included by mistake and is not supposed
to be there:
```ShellSession
$ base64 -w0 /etc/ssh/ssh_host_ed25519_key.pub
c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
```
The reason it did not cause issues before is because
Nix ignores everything after the `=`:
3dbf9b5af5/src/libutil/util.cc (L1539-L1540)
… so it's harmless but still worth fixing.
- Extensive documentation in NixOS manual
- Deterministic mode that fixes various identifiers relative to disk
partitions and filesystems in ext4 case
- UEFI variable recording
Building the nixpkgs manual currently triggers a bunch of deprecation
warnings, because every attribute in `lib` is evaluated to see if it's
an attrset to generate locations for.
Instead, share the lib subsets to include in the documentation
between `lib-function-docs` and `lib-function-locations` so they can
coordinate.
Also generate the list of sections instead of duplicating it in
`library.xml`.
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).
If all the docs are auto-generated, it should be easier to convert
them to Commonmark.

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.
Promote the `maintainers = with maintainers; [ ]` syntax as that is most common
in nixpkgs, and remove the `nix-env` example which doesn't work like that anymore.
The `sparseCheckout` argument allows the user to specify directories or
patterns of files, which Git uses to filter files it should check-out.
Git expects a multi-line string on stdin ("newline-delimited list", see
`git-sparse-checkout(1)`), but within nixpkgs it is more consistent to
use a list of strings instead. The list elements are joined to a
multi-line string only before passing it to the builder script.
A deprecation warning is emitted if a (multi-line) string is passed to
`sparseCheckout`, but for the time being it is still accepted.
It gives a warning on the lazy-trees branch of Nix
(NixOS/nix#6530)
one of these was also giving me an error (the one in lib/trivial probably)

A tricky thing about FreeBSD is that there is no stable ABI across
versions. That means that putting in the version as part of the config
string is paramount.
We have a parsed represenation that separates name versus version to
accomplish this. We include FreeBSD versions 12 and 13 to demonstrate
how it works.
https://github.com/NixOS/nixpkgs/pull/89885 ensures that fetches are
done securely (i.e. without `--insecure`) when the `hash` parameter is one of
the four special "fake" hashes. However the manual was not updated in that PR.
This commit updates the manual to account for the already-merged changes from
that PR.

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.
This was removed to simplify configuration. One could create a function that converts the plug format to vim native package format (only plugin system supported for neovim) and upstream it to nixpkgs if that's an issue
it is possible to maintain an out of tree list of neovim plugins with this method

This was a source of massive confusion for me when I first learned my way around nixpkgs' rust machinery. I seek to save others from that confusion.
* `buildRustPackage` should have been named `buildRustPackageUsingCargo`
* `buildRustCrate` should have been named `buildRustPackageUsingNix`
It is, unfortunately, too late to fix this. Let's do the next best thing and make the names `buildRustPackage` and `buildRustCrate` very prominent in the documentation, so readers see immediately that they need to learn the following jargon:
* `buildRustPackage` means "build this Rust crate by calling `cargo` in one (or two) monolithic derivations"
* `buildRustCrate` means "build this Rust crate by calling `rustc` in one derivation for each crate"
Fixes#186752. This adds buildVMMemorySize (defaults to 512 MiB) to
buildImage, which is passed to vm.runInLinuxVM. This is needed for
larger base images, which may otherwise cause container build failures
due to OOM in the VM.
Python package sets can be overridden by overriding an interpreter
and passing in `packageOverrides = self: super: {...};`. This is fine
in case you need a single interpreter, however, it does not help you
when you want to override all sets.
With this change it is possible to override all sets at once by
appending a list of "extensions" to `pythonPackagesExtensions`.
From reading the implementation you might wonder why a list is used, and
not
`lib.composeExtensions`? The reason is the latter requires knowledge of
the library function. This approach should be easier for most users
as it is similar to how we append to lists of e.g. inputs or patches
when overriding a derivation.
This section was broken out into its own file in efb55d2a42 but
apparently never actually got included anywhere.
Since then a more detailed section on using unfree packages has been
introduced.
Copied the introduction and removed the rest of the file.
This change mimics existing strip{All,Debug}List variables to
allow special stripping directories just for Target.
The primary use case in mind is gcc where package has to install
both host and target ELFs. They have to be stripped by their own
strip tools accordingly.

Fixed a few grammatical issues. Was uncertain how to address Treesitter, as the homepage itself is inconsistent, using all combinations of Treesitter, Tree-sitter, treesitter and tree-sitter.
