Qx devtools: ruff/mypy/pre-commit presets, code quality helpers

qx-devtools

Shared code-quality configuration presets for Qx services — ruff, mypy, pre-commit, and editorconfig in one place.

What lives here

• qx.devtools.RUFF_CONFIG — string constant with the standard ruff configuration (line length 100, full lint rule set, per-file ignores for tests and Alembic).
• qx.devtools.MYPY_CONFIG — string constant with strict mypy configuration (strict = True, pydantic plugin, test/alembic exclusions).
• qx.devtools.PRE_COMMIT_CONFIG — string constant with a pre-commit config that runs ruff, ruff-format, mypy, and standard file-hygiene hooks.
• qx.devtools.EDITORCONFIG — string constant with the standard .editorconfig (UTF-8, LF, 4-space indent).
• qx.devtools.write_configs — writes any combination of the above files into a target directory. Skips existing files unless overwrite=True.

Usage

Write the standard config files into a new service's root directory:

from pathlib import Path
from qx.devtools import write_configs

written = write_configs(Path("my-service/"), ruff=True, mypy=True, pre_commit=True)
print(f"Written: {[str(p) for p in written]}")

Or call it from the CLI during service scaffolding:

uv run python -c "from qx.devtools import write_configs; from pathlib import Path; write_configs(Path('.'))"

Design rules

• The config strings are plain text constants so services can read, extend, or compose from them without parsing TOML/YAML.
• write_configs is intentionally conservative: it never overwrites by default. Run with overwrite=True only when you want to pull in updated framework defaults.
• Services that want to diverge from a specific rule should do so in their own config file rather than forking the preset — extend, don't override wholesale.
