Ruff: An extremely fast Python linter and code formatter.

Usage: ruff [OPTIONS] <COMMAND>

Commands:
check    Run Ruff on the given files or directories
rule     Explain a rule (or all rules)
config   List or describe the available configuration options
linter   List all supported upstream linters
clean    Clear any caches in the current directory and any subdirectories
format   Run the Ruff formatter on the given files or directories
server   Run the language server
analyze  Run analysis over Python source code
version  Display Ruff's version
help     Print this message or the help of the given subcommand(s)

Options:
-h, --help     Print help
-V, --version  Print version

Log levels:
-v, --verbose  Enable verbose logging
-q, --quiet    Print diagnostics, but nothing else
-s, --silent   Disable all logging (but still exit with status code "1" upon detecting
               diagnostics)

Global options:
    --config <CONFIG_OPTION>  Either a path to a TOML configuration file (`pyproject.toml` or
                              `ruff.toml`), or a TOML `<KEY> = <VALUE>` pair (such as you might
                              find in a `ruff.toml` configuration file) overriding a specific
                              configuration option. Overrides of individual settings using this
                              option always take precedence over all configuration files,
                              including configuration files that were also specified using
                              `--config`
    --isolated                Ignore all configuration files

For help with a specific command, see: `ruff help <command>`.

# airflow-variable-name-task-id-mismatch (AIR001)

Derived from the **Airflow** linter.

## What it does
Checks that the task variable name matches the `task_id` value for
Airflow Operators.

## Why is this bad?
When initializing an Airflow Operator, for consistency, the variable
name should match the `task_id` value. This makes it easier to
follow the flow of the DAG.

## Example
```python
from airflow.operators import PythonOperator


incorrect_name = PythonOperator(task_id="my_task")

Use instead:

from airflow.operators import PythonOperator


my_task = PythonOperator(task_id="my_task")

airflow-dag-no-schedule-argument (AIR301)

Derived from the Airflow linter.

This rule is in preview and is not stable. The --preview flag is required for use.

What it does

Checks for a DAG() class or @dag() decorator without an explicit
schedule parameter.

Why is this bad?

The default schedule value on Airflow 2 is timedelta(days=1), which is
almost never what a user is looking for. Airflow 3 changes this the default
to None, and would break existing DAGs using the implicit default.

If your DAG does not have an explicit schedule argument, Airflow 2
schedules a run for it every day (at the time determined by start_date).
Such a DAG will no longer be scheduled on Airflow 3 at all, without any
exceptions or other messages visible to the user.

Example

from airflow import DAG


# Using the implicit default schedule.
dag = DAG(dag_id="my_dag")
