Per review feedback on #1745: rather than adding one boolean option per
HOMEBREW_NO_* env var, expose a generic onActivation.extraEnv attrset that
is prepended to brewBundleCmd alongside HOMEBREW_NO_AUTO_UPDATE=1. This
covers the same use case and the long tail of other HOMEBREW_NO_* vars
without tying the module to Homebrew's naming choices.
The global-scope booleans are dropped with no replacement — users who want
these variables set globally can write them directly into
environment.variables, so a global.extraEnv would be pure sugar.
Add options to control Homebrew environment variable hints, analytics
notices, and new formulae/casks reports during system activation and
manual brew commands.
These follow the existing autoUpdate pattern: boolean options that
default to true (preserving current behavior) and set the corresponding
HOMEBREW_NO_* environment variable when disabled.
onActivation options affect brew bundle during darwin-rebuild switch.
global options affect interactive brew commands via environment.variables.
Also make sure it merges correctly and verify with a test.
This was added in nixpkgs some time ago and is quite a nice addition as
it merges additively (in contrast to allowUnfreePredicate) thus allowing
to localize allowUnfreePackage specifications to all the locations in
your local config where unfree packages are added.
Closes#1032
Add `"check"` to the `onActivation.cleanup` enum. When set, nix-darwin runs
`brew bundle cleanup` during system checks to detect Homebrew packages that
are installed but not present in the generated Brewfile. If extra packages
are found, activation fails with a list of them and remediation steps.
Unlike `"uninstall"` and `"zap"`, the `"check"` mode never removes packages
-- it only reports. This runs during both `darwin-rebuild check` and
`darwin-rebuild switch`, matching the behavior of all other system checks.
Add `enableBashIntegration`, `enableFishIntegration`, and
`enableZshIntegration` options that evaluate `brew shellenv` to set up
Homebrew's environment and shell completions. This automates the
boilerplate that every nix-darwin Homebrew user currently writes manually.
All three shells use `interactiveShellInit`, consistent with direnv and
home-manager conventions. Fish additionally sets up completions paths in
the same hook.
