Every lint-* target depends on install-lint, which bootstraps the toolchain on
a bare interpreter. Reading the pins through utils.cache.yaml pulled PyYAML
into that path, so the whole lint stage died with 'ModuleNotFoundError: No
module named yaml' before a single linter ran.
pinned.py now reads the file through utils.cache.files.read_text and parses
its two-level shape itself; that import chain is stdlib-only. One test blocks
PyYAML via a meta_path finder in a subprocess to reproduce the bootstrap
condition, a second cross-checks the hand parser against PyYAML so the two
readings cannot drift apart.

utils/install
This directory hosts the Python implementation behind make install-lint.
For the general rules that govern READMEs in code directories see documentation.md.
Purpose
The package installs the lint toolchain (actionlint, shfmt, ruff, ansible-lint, mbake, markdownlint-cli2, eslint, shellcheck, ansible-playbook, ansible-galaxy) using the right channel per tool (system package manager, pip, npm, or GitHub release). Modules at this level are channel-agnostic primitives; per-tool policy lives one level down in lint/.
Structure
| File | Role |
|---|---|
primitives.py |
Logging, sudo wrapping, PATH mutation, and stdlib-based URL download. |
pip.py |
Venv-aware pip installer with --break-system-packages and --user fallback. |
npm.py |
Global / local npm install with per-user --prefix fallback. |
github_release.py |
Latest-tag resolver and asset downloader for GitHub releases. |
system_pkg.py |
Per-manager dispatch for pacman / apt-get / dnf / yum / brew. |
lint/ |
One module per tool, each exposing ensure(). See lint README. |
The CLI entry point lives at __main__.py, invoked from lint.sh as python3 -m utils.install.lint.
The matching dispatcher wrapper.sh routes make install-lint host vs container based on INFINITO_LINT_RUNNER.
File Naming
- Module names MUST stay lowercase snake_case.
- Channel-agnostic helpers MUST live directly under
utils/install/. - Per-tool policy (one tool per file) MUST live under
lint/(see lint README). - Test files live in tests/unit/utils/install/ and mirror the module name with a
test_prefix.
Import Rules
primitives.pyMUST NOT import from any other module in this package.pip.py,npm.py,github_release.py, andsystem_pkg.pyMAY import fromprimitives.py.npm.pyMAY import fromsystem_pkg.pyto bootstrap npm itself; no other cross-imports between these four are allowed.- Per-tool modules under
lint/MUST NOT import each other (see lint README).
