EduLint for VS Code

Integrates EduLint into VS Code.

This is a modified fork of matousekm/edulint-vscode. See License and attribution and CHANGELOG.md.

Usage

Whenever you open, save, or switch to a Python file, EduLint problems appear as squiggles and in the Problems panel. Each problem carries edulint's explanation (why it matters, plus examples) as related information, and an EduLint: explain <code> quick fix opens it in full.

You can also lint the current file explicitly:

EduLint: Run Linting from the Command Palette
Cmd+Alt+L / Ctrl+Alt+L
the editor title button

Requirements

Microsoft Python Extension
Python 3.10 or newer (see the note below)
EduLint v4.x installed as a Python package

Python version: edulint 4.3.1 declares Requires-Python: >=3.8, but on Python 3.9 it fails internally (isinstance with a typing.Union) and exits successfully with no findings at all. Use Python 3.10+.

Install edulint into the interpreter you use:

python3 -m pip install "edulint~=4.0"

If your project interpreter should not carry the linter, install edulint into a dedicated environment and point the extension at it:

python3.12 -m venv ~/.venvs/edulint
~/.venvs/edulint/bin/python -m pip install "edulint~=4.0"

then set edulint.pythonPath to ~/.venvs/edulint/bin/python.

Settings

Setting	Default	Description
`edulint.enable`	`true`	Run EduLint analysis on Python files.
`edulint.pythonPath`	`""`	Interpreter used to run edulint. Empty means the interpreter selected by the Python extension.
`edulint.lintOn`	`"all"`	`save`, `openAndSave`, or `all` (open, save, and active editor change).
`edulint.extraArgs`	`[]`	Extra arguments appended to `edulint check`.
`edulint.disableVersionCheck`	`true`	Pass `--disable-version-check` so edulint does not query PyPI while linting.
`edulint.showExplanations`	`true`	Attach edulint's explanation to each problem.

Commands

EduLint: Run Linting — analyse the current file and open the Problems view
EduLint: Check for Updates — compare the installed edulint with PyPI
EduLint: Install edulint Package — install edulint into the selected interpreter
EduLint: Show Explanation — shown as a quick fix on an EduLint problem, not in the palette
