From d4b00046d3b7797824950a48d953b1f0c854bea0 Mon Sep 17 00:00:00 2001 From: Kevin Veen-Birkenbach Date: Wed, 10 Dec 2025 16:26:23 +0100 Subject: [PATCH] Refine installer layering and Python/Nix integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Introduce explicit CLI layer model (os-packages, nix, python, makefile) and central InstallationPipeline to orchestrate installers. - Move installer orchestration out of install_repos() into pkgmgr.actions.repository.install.pipeline, using layer precedence and capability tracking. - Add pkgmgr.actions.repository.install.layers to classify commands into layers and compare priorities. - Rework PythonInstaller to always use isolated environments: PKGMGR_PIP override → active venv → per-repo venv under ~/.venvs/, avoiding system Python and PEP 668 conflicts. - Adjust NixFlakeInstaller to install flake outputs based on repository identity: pkgmgr/package-manager → pkgmgr (mandatory) + default (optional), all other repos → default (mandatory). - Tighten MakefileInstaller behaviour, add global PKGMGR_DISABLE_MAKEFILE_INSTALLER switch, and simplify install target detection. - Rewrite resolve_command_for_repo() with explicit Repository typing, better Python package detection, Nix/PATH resolution, and a library-only fallback instead of raising on missing CLI. - Update flake.nix devShell to provide python3 with pip and add pip as a propagated build input. - Remove deprecated/wip repository entries from config defaults and drop the unused config/wip.yml. https://chatgpt.com/share/69399157-86d8-800f-9935-1a820893e908 --- config/defaults.yaml | 22 -- config/wip.yml | 7 - flake.nix | 10 +- pkgmgr/actions/repository/install/__init__.py | 206 +++++--------- .../repository/install/installers/makefile.py | 72 ++--- .../install/installers/nix_flake.py | 109 ++++---- .../repository/install/installers/python.py | 160 ++++++----- pkgmgr/actions/repository/install/layers.py | 91 +++++++ pkgmgr/actions/repository/install/pipeline.py | 257 ++++++++++++++++++ pkgmgr/core/command/resolve.py | 253 +++++++++++------ .../installers/test_makefile_installer.py | 8 +- .../unit/pkgmgr/core/command/test_resolve.py | 93 ------- 12 files changed, 772 insertions(+), 516 deletions(-) delete mode 100644 config/wip.yml create mode 100644 pkgmgr/actions/repository/install/layers.py create mode 100644 pkgmgr/actions/repository/install/pipeline.py delete mode 100644 tests/unit/pkgmgr/core/command/test_resolve.py diff --git a/config/defaults.yaml b/config/defaults.yaml index bfb15a7..901dc69 100644 --- a/config/defaults.yaml +++ b/config/defaults.yaml @@ -380,17 +380,6 @@ repositories: - 44D8F11FD62F878E - B5690EEEBB952194 -- account: kevinveenbirkenbach - alias: infinito-presentation - description: This repository contains a Infinito.Nexus presentation designed for customers, end-users, investors, developers, and administrators, offering tailored content and insights for each group. - homepage: https://github.com/kevinveenbirkenbach/infinito-presentation - provider: github.com - repository: infinito-presentation - verified: - gpg_keys: - - 44D8F11FD62F878E - - B5690EEEBB952194 - - account: kevinveenbirkenbach description: A lightweight Python utility to generate dynamic color schemes from a single base color.
