collective.recipe.nix 0.17.0

Recipe options

eggs

list of packages to generate expressions for

name

string to define the used based filename in generated outputs (defaults to part name)

version

version string write into mkDerivation based expression (defaults to 1.0.0)

prefix

string to set prefix (or path) for generated outputs (defaults to working directory)

parts

list of existing buildout sections to install in mkDerivation based expression (defaults to all but the current section)

outputs

list of full generated expression filenames to filter outputs to be generated (defaults to nothing to generate all)

allow-from-cache

boolean (true) to allow generated expression to use package from buildout download cache (defaults to false)

build-inputs

list of additional build-inputs from nixpkgs for generated expressions (to be available in nix-shell environment) or list of package=nixpkgsPackage mappings to inject build-inputs for each package’s buildPythonPackage-expression

propagated-build-inputs

list of package=other.package mappings to inject additional requirements for packages (usually to enable some additional features)

nixpkgs

list of package=pythonPackages.package mappings to use existing packages from nixpkgs instead of generating custom buildPythonPackage (useful with package like Pillow, which need additional care to get built properly)

urls

list of package=url#md5=hash mappings to explicitly define package download URL and MD5 checksum for cases where the recipe fails to resolve it automatically

See the project repository for configuration examples.

Example of generic use

At first, define ./default.nix with buildout:

with import <nixpkgs> {}; {
  myEnv = stdenv.mkDerivation {
    name = "myEnv";
    buildInputs = [
      libxml2
      libxslt
      pythonPackages.ldap
      pythonPackages.pillow
      pythonPackages.readline
      pythonPackages.zc_buildout_nix
    ];
    shellHook = ''
      export SSL_CERT_FILE=~/.nix-profile/etc/ca-bundle.crt
    '';
  };
}

And example ./buildout.cfg:

[buildout]
parts = releaser

[releaser]
recipe = collective.recipe.nix
eggs = zest.releaser[recommended]

Run the buildout:

$ nix-shell --run buildout-nix

Now you should be able to run zest.releaser with recommended plugins with:

$ nix-shell releaser.nix --run fullrelease

Or install zest.releaser into your current Nix profile with:

$ nix-env -i -f releaser-zest_releaser.nix

See the project repository for more configuration examples.

Example of building Plone

Together with nixpkgs optimized buildout version (available in nixpkgs), this recipe can be used to build a Nix derivation using buildout install as in Nix derivation builder (see the generated mkDerivation based expression for current example implementation):

[buildout]
extends = https://dist.plone.org/release/4-latest/versions.cfg
parts = plone
versions = versions

[instance]
recipe = plone.recipe.zope2instance
eggs =
    Plone
    plone.app.ldap
user = admin:admin
var = /tmp

[plone]
recipe = collective.recipe.nix
parts = instance
eggs = ${instance:eggs}
outputs = plone.nix

[versions]
Pillow =
setuptools =
zc.buildout =
zc.recipe.egg =

$ nix-shell --run buildout-nix
$ nix-build plone.nix -o plone
$ plone/bin/instance fg
