nix-template's Introduction

Nix-template

NOTE: This is still WIP, but should be useful in most situations

Make creating nix expressions easy. Provide a nice way to create largely boilerplate nix-expressions.

Roadmap

Current Usage (--from-url, github and pypi only)

$ nix-template rust -n --from-url github.com/jonringer/nix-template

Current Usage (Generically)

# only need to config once per user

# add a package
$ nix-template python --nixpkgs --pname requests -f pypi -l asl20

Installation

from nixpkgs (unstable, not available in 20.03):

$ nixenv -iA nix-template

with nix-cli (from this repository):

$ nix-env -f default.nix -iA ""

with cargo

$ cargo install --path .

Development

Installing depedencies on nixpkgs:

nix-shell
# or
nix develop

Other platforms, you'll need the following dependencies:

cargo
rustc
rust-clippy

End Goal (Only better nixpkgs support missing)

# only need to config once per user
$ nix-template config name jonringer
$ nix-template config nixpkgs-root /home/jon/projects/nixpkgs

# add a package
$ nix-template python --nixpkgs -u https://pypi.org/project/requests/
Determining latest release for requests

Generating python expression at /home/jon/projects/nixpkgs/pkgs/development/python-modules/requests/default.nix
For an addition to nixpkgs as a python package, please add the following to pkgs/top-level/python-packages.nix:

  requests = callPackage ../development/python-modules/requests { };

For an addition to nixpkgs as a python application, please add the following to pkgs/top-level/all-packages.nix:

  requests = with python3Packages; toPythonApplication requests { };

{ lib
, buildPythonPackage
, fetchPypi
}:

buildPythonPackage rec {
  pname = "requests";
  version = "2.26.0";

  src = fetchPypi {
    inherit pname version;
