0eae4bfad1 reword overview with clear terminology
trying to capture alternative terms in one go here, mirroring everyday
use:

derivation - build plan
realise - execute build

there will be more of that sort.

0737094161 Add draft "Rosetta stone" by @fricklerhandwerk and stub commentary
The idea and most of the execution are @fricklerhandwerk's. I changed a
few things best I could based on @edolstra's corrections, and a Bazel
glossary.

523359d133 WIP: Document the design of Nix
The current docs are all "how to do things" and no "what is Nix" or "why
are things the way they are".

I see lots of misconception on the wider internet, and I also think we
would benefit from a "living document" to answer some questions people
currently turn to the thesis for.

I think a new section of the manual can address all these issues.

499ed26508 manual: remove "Writing Nix Expressions" chapter

- update redirects and internal links
- use "Nix language" consistently

649c9d9b4c doc: acknowledge post-rsync reality
Before #5150 the copy-to-store phase of the install was idempotent,
but the recursive cp isn't. This is probably baiting a few people

- For expressions/advanced-attributes.md

    s~^  - `([^`]+)`~  - [`\1`]{#adv-attr-\1}~g

  and manually adjusted outputHashAlgo & outputHashMode.

- For glossary.md

    s~^  - (`([^`]+)`|(.+)) ?\\~  - [\1]{#gloss-\2\3}\\~g;
    s~(gloss-\w+) ~\1-~g

  and manually adjusted anchors for Nix expression, user environment, NAR, ∅ and ε.

- For command-ref/env-common.md

4de84e095d doc: Introduce pre-processor for adding anchors to text
It is now possible to use the following syntax to insert anchors into the text:

    []{#anchor-name}

The anchor will allow linking to the location it is placed by appending #anchor-name to the URL.

Additionally, it is possible to create a link pointing to its own location by adding text between the square brackets:

    [`--add-root`]{#opt-add-root}

5b8c1deb18 fetchTree: Allow fetching plain files
Add a new `file` fetcher type, which will fetch a plain file over
http(s), or from the local file.

Because plain `http(s)://` or `file://` urls can already correspond to
`tarball` inputs (if the path ends-up with a know archive extension),
the URL parsing logic is a bit convuluted in that:

- {http,https,file}:// urls will be interpreted as either a tarball or a
  file input, depending on the extensions of the path part (so
  `https://foo.com/bar` will be a `file` input and
  `https://foo.com/bar.tar.gz` as a `tarball` input)
- `file+{something}://` urls will be interpreted as `file` urls (with
  the `file+` part removed)
- `tarball+{something}://` urls will be interpreted as `tarball` urls (with
  the `tarball+` part removed)

nix repl: make symlinks with the :bl command
Requested by ppepino on the Matrix:

This adds a new command, :bl, which works like :b but also creates
a GC root symlink to the various derivation outputs.

660c19eb49 manual: Add some anchor targets for the nix.conf options
For each `nix.conf` option, add an empty html node with a unique `id`
that can be used as an anchor target. Also make the name of the option
be a link to that target so that it’s easily discoverable.

We can’t rewrite the whole list as an html definition list like it’s
done for the builtins because these options also appear in a man page,
and the manpage renderer (lowdown) can’t render arbitrary html. But the
hack here allows to keep the manpage and have the links in the html
version.

2799fe4cdb enable LTO in optimized builds
gives 2-5% performance improvement across a board of tests.
LTO is broken when using clang; some libs link fine while others crash
the linker with a segfault in the llvm linker plugin. 🙁

doc: Add detailed uninstall section for macOS
The multi-user installation on macOS, which is now the only option, has
gotten complicated enough that it discourages some users from checking
Nix out for fear of being left with a "dirty" system. Detailed
uninstallation instructions should make this less of an issue.

00c993f48b add zipAttrsWith primop
nixpkgs can save a good bit of eval memory with this primop. zipAttrsWith is
used quite a bit around nixpkgs (eg in the form of recursiveUpdate), but the
most costly application for this primop is in the module system. it improves
the implementation of zipAttrsWith from nixpkgs by not checking an attribute
multiple times if it occurs more than once in the input list, allocates less
values and set elements, and just avoids many a temporary object in general.

nixpkgs has a more generic version of this operation, zipAttrsWithNames, but
this version is only used once so isn't suitable for being the base of a new
primop. if it were to be used more we should add a second primop instead.

31313d1401 Replace the trailing markdown spaces by a backslash
They are equivalent according to
<https://spec.commonmark.org/0.29/#hard-line-breaks>,
and the trailing spaces tend to be a pain (because the make git
complain, editors tend to want to remove them − the `.editorconfig`
actually specifies that − etc..).

Initialize plugins after handling initial command line flags
This is technically a breaking change, since attempting to set plugin
files after the first non-flag argument will now throw an error. This
is acceptable given the relative lack of stability in a plugin
interface and the need to tie the knot somewhere once plugins can
actually define new subcommands.

Adds Nix CLI Guideline to docs
As we are working towards Nix 3.0 we want to make sure that we make a
huge step forward in Nix's user experience. And once 3.0 is out of the
door we need to make sure that all future commands and features keep up
the standard of user experience.

This PR adds a CLI guideline document to the Nix documentation. Consider
this document a good starting point and a checklist when somebody will
be (re)implementing commands.

Clearly this guideline does nothing to improve user experience on its
own and can only be useful as long as it is going to be read and
cared for. But it is a first step into that direction.

Fix macOS sandbox build
Since c4c3c15c19 (#4251) building Nix for
macOS with sandboxing fails:
```
getting status of /nix/var/nix/profiles/per-user/root/channels/nixpkgs: Operation not permitted
```

This happens, because `EvalSettings::getDefaultNixPath` tries to access
paths outside the sandbox. Since the state-dir is not required for
doc generation, it is set to the dummy folder. This needs to be done
for all nix invocations during doc generation, as
`EvalSettings::getDefaultNixPath` is called unconditionally.

nix-prefetch-url: Add --executable flag
pkgs.fetchurl supports an executable argument, which is especially nice
when downloading a large executable. This patch adds the same option to
nix-prefetch-url.

I have tested this to work on the simple case of prefetching a little
executable:

1. nix-prefetch-url --executable https://my/little/script
2. Paste the hash into a pkgs.fetchurl-based package, script-pkg.nix
3. Delete the output from the store to avoid any misidentified artifacts
4. Realise the package script-pkg.nix
5. Run the executable

I repeated the above while using --name, as well.

I suspect --executable would have no meaningful effect if combined with
--unpack, but I have not tried it.

641c950701 Add hashed-mirrors back
Some users have their own hashed-mirrors setup, that is used to mirror
things in addition to what’s available on tarballs.nixos.org. Although
this should be feasable to do with a Binary Cache, it’s not always
easy, since you have to remember what "name" each of the tarballs has.
Continuing to support hashed-mirrors is cheap, so it’s best to leave
support in Nix. Note that NIX_HASHED_MIRRORS is also supported in
Nixpkgs through fetchurl.nix.

Note that this excludes tarballs.nixos.org from the default, as in
\#3689. All of these are available on cache.nixos.org.

libutil/logging: extend internal-json logger to make it more machine-readable
The new error-format is pretty nice from a UX point-of-view, however
it's fairly hard to parse the output e.g. for editor plugins such as
vim-ale[1] that use `nix-instantiate --parse` to determine syntax errors in
Nix expression files.

This patch extends the `internal-json` logger by adding the fields
`line`, `column` and `file` to easily locate an error in a file and the
field `raw_msg` which contains the error-message itself without
code-lines and additional helpers.

An exemplary output may look like this:

```
[nix-shell]$ ./inst/bin/nix-instantiate ~/test.nix --log-format minimal
{"action":"msg","column":1,"file":"/home/ma27/test.nix","level":0,"line":4,"raw_msg":"syntax error, unexpected IF, expecting $end","msg":"<full error-msg with code-lines etc>"}
```

Nix installation now requires following redirects using `curl -L`. This

Using `curl` without the `-L` flag results in an empty body, making

focus on golden-path covering most scenarios
This should handle installation scenarios we can handle with
anything resembling confidence. Goal is approximating the existing
setup--not enforcing a best-practice...

Approaches (+ installer-handled, - manual) and configs each covers:

+ no change needed; /nix OK on boot volume:
  All pre-Catalina (regardless of T2 or FileVault use)

+ create new unencrypted volume:
  Catalina, pre-T2, no FileVault

+ create new encrypted-at-rest volume:
  Catalina, pre-T2, FileVault
  Catalina, T2, no FileVault

- require user to pre-create encrypted volume
  Catalina, T2, FileVault

Remove -j option from simple-build-testing
By default Nix/NixOS already set a reasonable default `max-jobs = auto`
so we don't need to mention it in this tutorial.
The option is still documented in other parts of the documentation
if users ever stumble over this.

Update "Upgrading Nix" documentation
This PR proposes two changes to the "Upgrading Nix" documentation:

* Besides updating `nixpkgs.nix`, we also update `nixpkgs.cacert`, so that the certificates are up-to-date as well.
* Add the instructions for multi-user mode on Linux.

Motivation: maintain project-level configuration files.

Document the whole situation a bit better so that it corresponds to the
implementation, and add NIX_USER_CONF_FILES that allows overriding
which user files Nix will load during startup.

e40e01c1dd doc: Files in the store have modes 444/555, not 644/755
This line has been this way since it was written, in 9e08f5efe
in 2006.

I think it was just a small mistake then; Eelco's thesis earlier
that year says the permission on each file is set to 0444 or 0555
in a derivation's output as part of the build process.  In any
case I'm pretty sure that's the behavior now.

c5a488afc0 Remove the --delete option for --gc
Running `nix-store --gc --delete` will, as of Nix 2.3.3, simply fail
because the --delete option conflicts with the --delete operation.

  $ nix-store --gc --delete
  error: only one operation may be specified
  Try 'nix-store --help' for more information.

Furthermore, it has been broken since at least Nix 0.16 (which was
released sometime in 2010), which means that any scripts which depend
on it should have been broken at least nine years ago. This commit
simply formally removes the option. There should be no actual difference
in behaviour as far as the user is concerned: it errors with the exact
same error message. The manual has been edited to remove any references
to the (now gone) --delete option.

Other information:
* Path for Nix 0.16 used:
  /nix/store/rp3sgmskn0p0pj1ia2qwd5al6f6pinz4-nix-0.16

style.css: Remove
This file is licensed under the GPL. Originally, Nix was also
GPL-licensed so that was fine. However, we later changed the license
to the LGPL but missed the fact that style.css has an incompatible
license.

Since the Nix manual at nixos.org uses its own styling, we can remove
this file.

- At the top of the release notes, we announce sandboxing is now enabled by default,
then at the bottom it says it's now disabled when missing kernel support. These
can be merged into one point for clarity.

- The point about `max-jobs` defaulting to 1 appears unrelated to sandboxing.

Add a post-build-hook
Passing `--post-build-hook /foo/bar` to a nix-* command will cause
`/foo/bar` to be executed after each build with the following
environment variables set:

    DRV_PATH=/nix/store/drv-that-has-been-built.drv
    OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev

This can be useful in particular to upload all the builded artifacts to
the cache (including the ones that don't appear in the runtime closure
of the final derivation or are built because of IFD).

This new feature prints the stderr/stdout output to the `nix-build`
and `nix build` client, and the output is printed in a Nix 2
compatible format:

    [nix]$ ./inst/bin/nix-build ./test.nix
    these derivations will be built:
      /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv
    building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'...

57daa860e8 autoconf: Fix C++17 detection not working on Ubuntu 16.04.
And probably many other distributions.

Until now, ./configure would fail silently printing a warning

    ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found

and then continuing, later failing with a C++ #error saying that some C++11
feature isn't supported (it didn't even get to the C++17 features).

This is because older distributions don't come with the
`AX_CXX_COMPILE_STDCXX_17` m4 macro.

This commit vendors that macro accordingly.

Now ./configure complains correctly:

    configure: error: *** A compiler with support for C++17 language features is required.

On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with
gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
using:

    ./bootstrap.sh
    ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)

1f97b16b1d autoconf: Work around editline not being found on Ubuntu 16.04.
And probably other Linux distributions with long-term support releases.

Also update manual stating what version is needed;
I checked that 1.14 is the oldest version with which current nix compiles,
and added autoconf feature checks for some functions added in that release
that nix uses.

doc: clarify that optional attrs in a function argument will be ignored unless specified
In `args@{ a ? 1 }: /* ... */` the value `a` won't be a part of `args`
unless it's specified when calling the function, the default value will
be ignored in this case.

My personal point of view is that this behavior is a matter of taste, at
least I was pretty sure that unmatched arguments will be a part of
`args@` while debugging some Nix code last week.

I decided to add a warning to the docs which hopefully reduces the
confusion of further Nix developers who thought the same about `args@`.

3f192ac80c Add builtins.hashFile
For text files it is possible to do it like so:
`builtins.hashString "sha256" (builtins.readFile /tmp/a)`
but that doesn't work for binary files.

With builtins.hashFile any kind of file can be conveniently hashed.

288f93cec0 manual: "Nix Package collection" -> "Nixpkgs package collection".
Makes difference between Nix and Nixpkgs clearer to avoid
some common confusion this sentence on IRC.

Also disambiguate an "it" reference.
