nixpkgs-pytools 1.1.2

Tools for removing the tedious nature of creating nixpkgs derivations

python nixpkgs tools

These are scripts written to remove the tedious nature of creating nix package derivations for nixpkgs. The goal of these scripts is not to create a perfect package derivation but complete as much as possible and guide the user on necessary changes.

python-package-init

usage: python-package-init [-h] [--version VERSION] [--filename FILENAME] [--stdout] [--nixpkgs-root NIXPKGS_ROOT] [-f] package

positional arguments:
  package               pypi package name

optional arguments:
  -h, --help            show this help message and exit
  --version VERSION     pypi package version (stable if not specified)
  --filename FILENAME   filename for nix derivation
  --stdout              Print the nix derivation to stdout
  --nixpkgs-root NIXPKGS_ROOT
                        Root directory of nixpkgs
  -f, --force           Force creation of file, overwriting when it already exists

python-package-init now has the ability to create a <package-name> = callPackages ../...<package-name> { }; in pkgs/top-level/python-modules.nix and write the default.nix to pkgs/development/python-modules/<package-name>/default.nix with a nearly complete derivation.

Example lets add nixpkgs-pytools to nixpkgs. It is already in nixpkgs so you would need to provide the -f (force) option to force it to be written to nixpkgs.

nix-shell -p nixpkgs-pytools
python-package-init nixpkgs-pytools --nixpkgs-root=<path to nixpkgs>

Creates a default.nix derivation to go into nixpkgs/pkgs/development/python-modules/<pypi-name>/default.nix. This script is overly verbose so that you don't have to remember the name of attributes. Delete the ones that you don't need.

Hacking on these tools

nix-shell will load the correct environment for your usage:
