Previously, it was not possible to inject PATH entries between profiles
and the “default system” PATH entries. This confounds adding, e.g.
Homebrew on aarch64’s non-standard prefix as higher priority than the
builtin system paths, but lower than Nix profiles.
This is a backwards-incompatible change for some users, but should only
be so in the case a user used `mkOrder` with a value between 1000 (the
default priority) and 1200. Value of 1200 chosen as the same delta from
the default as just below in `environment.profiles` (which uses 800),
and mkAfter is 1500 so will still go after this.
This process was automated by [my fork of `nix-doc-munge`]; thanks
to @pennae for writing this tool! It automatically checks that the
resulting documentation doesn't change, although my fork loosens
this a little to ignore some irrelevant whitespace and typographical
differences.
As of this commit there is no DocBook remaining in the options
documentation.
You can play along at home if you want to reproduce this commit:
$ NIX_PATH=nixpkgs=flake:nixpkgs/c1bca7fe84c646cfd4ebf3482c0e6317a0b13f22 \
nix shell nixpkgs#coreutils \
-c find . -name '*.nix' \
-exec nix run github:emilazy/nix-doc-munge/0a7190f600027bf7baf6cb7139e4d69ac2f51062 \

This should enable `nix run` to work under shells like fish and zsh,
as well as making child shells not needlessly reset any environment
that should be inherited.
Implementation adapted from NixOS.
This simplifies using a non default configuration.nix without requiring
a symlink or redefining NIX_PATH.
The nix.nixPath option only defines a default which means defining a value
will drop all of the defaults. This is because correct merge behaviour
isn't very clear for named entries.
Don't extend initial PATH adding extra entries should be done through
appending environment.systemPath or manually extending it with
environment.extraInit or similar options.
Your user-specific profile should take precedence
over the system one. If I've gone out of my way
to install something into my personal profile, my
version should be used instead of the system's.
