Nix now provides better integration with zsh's run-help feature. It is now included in the Nix installation in the form of an autoloadable shell function, run-help-nix. It picks up Nix subcommands from the currently typed in command and directs the user to the associated man pages.
nix replhas a new build-'n-link (
:bl) command that builds a derivation while creating GC root symlinks.
The path produced by
builtins.toFileis now allowed to be imported or read even with restricted evaluation. Note that this will not work with a read-only store.
nix buildhas a new
--print-out-pathsflag to print the resulting output paths. This matches the default behaviour of
You can now specify which outputs of a derivation
nixshould operate on using the syntax
nixpkgs#glibc^*. By default,
nixwill use the outputs specified by the derivation's
meta.outputsToInstallattribute if it exists, or all outputs otherwise.
Selecting derivation outputs using the attribute selection syntax (e.g.
nixpkgs#glibc.dev) no longer works.
