Languages and frameworks
The standard build environment makes it easy to build typical Autotools-based packages with very little code. Any other kind of package can be accommodated by overriding the appropriate phases of stdenv
. However, there are specialised functions in Nixpkgs to easily build packages for other programming languages, such as Perl or Haskell. These are described in this chapter.
Each supported language or software ecosystem has its own package set named <language or ecosystem>Packages
, which can be explored in various ways:
-
Search on search.nixos.org
For example, search for
haskellPackages
orrubyPackages
. -
Navigate attribute sets with
nix repl
.This technique is generally useful to inspect Nix language data structures.
:::{.example #example-navigte-nix-repl}
Navigate Java compiler variants in
javaPackages
withnix repl
$ nix repl '<nixpkgs>' -I nixpkgs=channel:nixpkgs-unstable nix-repl> javaPackages.<tab> javaPackages.compiler javaPackages.openjfx15 javaPackages.openjfx21 javaPackages.recurseForDerivations javaPackages.jogl_2_4_0 javaPackages.openjfx17 javaPackages.openjfx22 javaPackages.mavenfod javaPackages.openjfx19 javaPackages.override javaPackages.openjfx11 javaPackages.openjfx20 javaPackages.overrideDerivation
:::
-
List all derivations on the command line with
nix-env --query
.nix-env
is the only convenient way to do that, as it will skip attributes that fail assertions, such as when a package is marked as broken, rather than failing the entire evaluation.:::{.example #example-list-haskellPackages}
List all Python packages in Nixpkgs
The following command lists all derivations names with their attribute path from the latest Nixpkgs rolling release (
nixpkgs-unstable
).$ nix-env -qaP -f '<nixpkgs>' -A pythonPackages -I nixpkgs=channel:nixpkgs-unstable
pythonPackages.avahi avahi-0.8 pythonPackages.boost boost-1.81.0 pythonPackages.caffe caffe-1.0 pythonPackages.caffeWithCuda caffe-1.0 pythonPackages.cbeams cbeams-1.0.3 …
