how the different invocations relate to each other seems be
confusing, which is relatable because one has to wire it up in your head
while reading. an explicit reference should make it unambiguous and
easier to notice due to links being highlighted.
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.
Single quotes are a basic feature of shell syntax that people expect to
work. They are also more convenient for writing literal code expressions
with less escaping.
there is a very confusing warning in the Nixpkgs manual that
mischaracterises `nix-env` behavior, and this example shows what's
really happening.
note that it doesn't use `pkgs.runCommand` or other `pkgs.stdenv`
facilities, as deep down those set `meta.outputsToInstall` to very
particular defaults that do not generally apply to Nix.
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.
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.
- Improved API docs from comment
- Exit codes are for `nix-build`, not just `nix-store --release`
- Make note in tests so the magic numbers are not surprising
Picking up where #8387 left off.
Deleting store info corrected (there is a foot-gun in Nix with
`--delete-generations old`!)
Also a few things are cleaned up based on feedback.

Add support to --list-generations
as another way to say
nix-env --profile /nix/var/nix/profiles/per-user/$USER/channels --list-generations
the way we did for nix-channel --rollback [generation id]
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.
This gives some more context and should clarify why it works that way.
Also link it from the section on `NIX_USER_CONF_FILES`.
