3.1.0 (27 Nov 2020)

flakes lib, cli improvements, bugfixes

Features

• expose the following functions via flakes lib:
  • mkPython / mkPythonShell / mkDockerImage / mkOverlay / mkNixpkgs / mkPythonOverrides
  • buildPythonPackage / buildPythonApplication
  • fetchPypiSdist / fetchPypiWheel
• Properly manage and lock versions of nixpkgs and mach-nix for environments created via mach-nix env command.
• Add example on how to use mach-nix with jupyterWith

Improvements

• Improve portability of mach-nix env generated environments. Replace the platform specific compiled nix expression with a call to mach-nix itself, which is platform agnostic.
• Mach-nix now produces the same result no matter if it is used through flakes or legacy interface. The legacy interface now loads its dependencies via flakes.lock.

Fixes

• mkDockerImage produced corrupt images.
• non-python packages passed via packagesExtra were not available during runtime. Now they are added to the PATH.
• remove <nixpkgs> impurity in the dependency extractor used in buildPythonPackage.
