import: Remove Nix importer.
This importer has suffered from bitrot and no longer works with current Nix and Nixpkgs. See <https://bugs.gnu.org/32339> and <https://bugs.gnu.org/36255>. * guix/import/snix.scm, guix/scripts/import/nix.scm, tests/snix.scm: Remove. * Makefile.am (MODULES, SCM_TESTS): Remove them. * guix/scripts/import.scm (importers): Remove "nix". * build-aux/test-env.in: Remove NIXPKGS variable. * configure.ac: Remove '--with-nixpkgs' option. * doc/guix.texi (Invoking guix import): Remove bit about "guix import nix". * etc/completion/fish/guix.fish: Likewise.

Import metadata from a local copy of the source of the
|
||||
@uref{https://nixos.org/nixpkgs/, Nixpkgs distribution}@footnote{This
|
||||
relies on the @command{nix-instantiate} command of
|
||||
@uref{https://nixos.org/nix/, Nix}.}. Package definitions in Nixpkgs are
|
||||
typically written in a mixture of Nix-language and Bash code. This
|
||||
command only imports the high-level package structure that is written in
|
||||
the Nix language. It normally includes all the basic fields of a
|
||||
package definition.
|
||||
|
||||
When importing a GNU package, the synopsis and descriptions are replaced
|
||||
by their canonical upstream variant.
|
||||
|
||||
Usually, you will first need to do:
|
||||
|
||||
@example
|
||||
export NIX_REMOTE=daemon
|
||||
@end example
|
||||
|
||||
@noindent
|
||||
so that @command{nix-instantiate} does not try to open the Nix database.
|
||||
|
||||
As an example, the command below imports the package definition of
|
||||
LibreOffice (more precisely, it imports the definition of the package
|
||||
bound to the @code{libreoffice} top-level attribute):
|
||||
|

@example
|

guix import nix ~/path/to/nixpkgs libreoffice
