eldritch horrors 14088e1ec5 docs: remove many link-to-self
for some reason these three were anchors, not links, but had they been
links they wouldn't've worked because they're not defined anywhere but
here. in the print version of the manual they're duplicated many times
over (creating id collisions), so we should better remove them anyway.

Qyriad 9166babbaf Revert "meson: move nix3 manpage generation into command-ref/"
This reverts commit 70954233743a233744787103d3211237a28ddbca.

This seems to have broken running ninja on warm build directories, which
is not what we want. Reverted until we figure out something better

Qyriad c96c5db030 meson: move nix3 manpage generation into command-ref/
This puts the generated files where they are for the make system.
This is in preparation for further meson-mdbook stuff.

Rebecca Turner 2a98ba8b97 Add pre-commit checks
The big ones here are `trim-trailing-whitespace` and `end-of-file-fixer`
(which makes sure that every file ends with exactly one newline
character).

eldritch horrors 512c1f05c3 Unify and refactor value printing
Previously, there were two mostly-identical value printers -- one in
`libexpr/eval.cc` (which didn't force values) and one in
`libcmd/repl.cc` (which did force values and also printed ANSI color
codes).

This PR unifies both of these printers into `print.cc` and provides a
`PrintOptions` struct for controlling the output, which allows for
toggling whether values are forced, whether repeated values are tracked,
and whether ANSI color codes are displayed.

Additionally, `PrintOptions` allows tuning the maximum number of
attributes, list items, and bytes in a string that will be displayed;
this makes it ideal for contexts where printing too much output (e.g.
all of Nixpkgs) is distracting. (As requested by @roberth in
https://github.com/NixOS/nix/pull/9554#issuecomment-1845095735)

Please read the tests for example output.

Future work:
- It would be nice to provide this function as a builtin, perhaps
  `builtins.toStringDebug` -- a printing function that never fails would
  be useful when debugging Nix code.
- It would be nice to support customizing `PrintOptions` members on the
  command line, e.g. `--option to-string-max-attrs 1000`.

Restore ambiguous value printer for `nix-instantiate`

The Nix team has requested that this output format remain unchanged.
I've added a warning to the man page explaining that `nix-instantiate
--eval` output will not parse correctly in many situations.

Valentin Gagarin 02c2679f0e dedent common options listing; one sentence per line
this is a pure reformatting, contents were not changed

one sentence per line makes reviewing diffs and making suggestions much
more convenient. the indentation was an artifat of the DocBook
migration.

Valentin Gagarin ee72ede389 remove the Channels section
this is a how-to guide which should not be in the reference manual.
it also refers to `nix-env`, which should not be the first thing readers
of the reference manual encounter, as it behaves very differently in
spirit from the rest of Nix.

slightly reword the documentation to be more concise and informative.

John Ericson 97df060588 Better document build failure exit codes

- Exit codes are for `nix-build`, not just `nix-store --release`

- Make note in tests so the magic numbers are not surprising

Alexander Schmolck 8d4b6766e2 Convert short nix options to long ones
e.g. nix-env -e subversion => nix-env --uninstall subversion

The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.

The change was made with the following script:

<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>

and sanity checked visually.

Valentin Gagarin f8620758aa display documentation on manifest files separately
it's probably better not to show the manifest file documentation in the
command-specific pages, because these are implementation details that are not really practically useful.

this means no additional hassle for building the manual, but clutters
the table of contents a bit.
