this form is much easier to maintain (also with minimal diffs), and
allows for more details on each operator.
this change a purely mechanical transformation, without changing any contents.
Adds a new boolean structured attribute
`outputChecks.<output>.unsafeDiscardReferences` which disables scanning
an output for runtime references.
__structuredAttrs = true;
outputChecks.out.unsafeDiscardReferences = true;
This is useful when creating filesystem images containing their own embedded Nix
store: they are self-contained blobs of data with no runtime dependencies.
Setting this attribute requires the experimental feature
`discard-references` to be enabled.
This makes 'nix develop' set the Linux personality in the same way
that the actual build does, allowing a command like 'nix develop
nix#devShells.i686-linux.default' on x86_64-linux to work correctly.
First, logic is consolidated in the shell script instead of being spread
between them and makefiles. That makes understanding what is going on a
little easier.
This would not be super interesting by itself, but it gives us a way to
debug tests more easily. *That* in turn I hope is much more compelling.
See the updated manual for details.

* doc/book.toml: Improve config
- `title` value will be added to the HTML <title> - here</title>
- `git-repository-url` adds a link to the GitHub repo in the top right corner
- `edit-url-template` adds an edit link, inviting contributions

this avoids incorrect rendering on the man pages, since `lowdown`
neither parses the anchor syntax nor HTML.
this should rather be fixed in lowdown, as adding more anchors
would otherwise produce ever more noise and error-prone repetition.
* docs: Use secret-key-files when demonstrating post-build-hooks
The docs used to recommend calling `nix store sign` in a post-build
hook, but on more recent versions of nix, this results in unsigned
store paths being copied into binary caches. See
https://github.com/NixOS/nix/issues/6960 for details.
Instead, use the `secret-key-files` config option, which signs all
locally-built derivations with the private key.

These only functioned if a very narrow combination of conditions held:
- The result path does not yet exist (--check did not result in
repeated builds), AND
- The result path is not available from any configured substituters, AND
- No remote builders that can build the path are available.
If any of these do not hold, a derivation would be built 0 or 1 times
regardless of the repeat option. Thus, remove it to avoid confusion.
this is a quick half-fix for command line examples, as discussed
discussed in [1].

examples which look like this
$ foo bar
baz
are confusing for Unix shell beginners, because it's hard to discern
what is supposed to be entered into the actual command line when the
convention of prefixing `$` is not known, as barely any real-world shell
looks that way any more.
this change prevents selecting the prompt part with the mouse in the
HTML representation of the Nix manual.
it does not prevent selecting the output part of the shell example.
it also does not address that the copy button provided by mdBook takes
the entire sample, including the prompts, into the clipboard.
