conda-env does not exist after entering the conda-shell without first calling conda-install, so I think the wiki is missleading here, or the package has a bug. | conda-env does not exist after entering the conda-shell without first calling conda-install, so I think the wiki is missleading here, or the package has a bug. | ||
conda-shell, conda-install have no effect and nothing happens. Bash just says it can't find that command. | |||

== Flake example for use with nix develop == | |||
I was trying to get python with packages as defined by a flake, and found https://dev.to/deciduously/workspace-management-with-nix-flakes-jupyter-notebook-example-2kke a useful discussion. I propose to add an example: | |||
<syntaxHighlight lang="nix"> | |||
{ | |||
description = "Python environment"; | |||
inputs.nixpkgs.url = "nixpkgs/nixos-22.11"; | |||
outputs = {nixpkgs, ...}: let | |||
system = "x86_64-linux"; | |||
pkgs = import nixpkgs {inherit system;}; | |||
in { | |||
devShells.${system}.default = pkgs.mkShell { | |||
buildInputs = [ | |||
(pkgs.python3.withPackages (p: [ | |||
p.requests | |||
])) | |||
]; | |||
shellHook = "python"; | |||
}; | |||
}; | |||
} | |||
</syntaxHighlight> | |||
== Full == | |||
Can we add a section about Full (e.g. python312Full) and non-Full (e.g. python312) versions? Whats the difference and in which situation use on or the other? | |||
== Update the packaging section == | |||
Seems like the format was updated and the wiki is no longer accurate? Specifically the <code>setup.py</code> format | |||
Wiki says that the result of <code>main.py</code> will be in bin/app.py but the resulting filename isn't being renamed, so it should be main.py | |||
Setuptools now aren't included by default and need to be explicitly mentioned, and pyproject variable set to true, so the example nix file would look something like this: | |||
<syntaxhighlight lang="nix"> | |||
{ pkgs ? import <nixpkgs> { } }: | |||
pkgs.python3Packages.buildPythonApplication { | |||
pname = "myFlaskApp"; | |||
version = "0.1.0"; | |||
src = ./src; | |||
build-system = with pkgs.python3Packages; [ | |||
setuptools | |||
]; | |||
propagatedBuildInputs = with pkgs.python3Packages; [ | |||
flask | |||
]; | |||
pyproject = true; | |||
} | |||
