## Features

__noqaexplain__ is a linter which enforces justifying every ignored linting rule
supporting __multiple formats/linters__:

- __Python__ -[`ruff`](https://github.com/astral-sh/ruff) and
    [`flake8`](https://github.com/PyCQA/flake8) `# noqa`,
    [`coveragepy`](https://github.com/nedbat/coveragepy) `# pragma: no cover`
- __JavaScript/TypeScript__ - [`eslint`](https://github.com/eslint/eslint)
- __Rust__ - [`clippy`](https://github.com/rust-lang/rust-clippy)
- __Dockerfiles__ - [`hadolint`](https://github.com/hadolint/hadolint)
- __YAML__ - [`yamllint`](https://github.com/adrienverge/yamllint)
- __Shell__ - [`shellcheck`](https://www.shellcheck.net/)

> [!IMPORTANT]
> You can expand this list with __any__ language and linter by using
> `extend_suffix_mapping` and/or `extend_name_mapping`!
> __Feel free to open a request to add support for more linters.__

## Quick start

### Installation

> [!TIP]
> You can use your favorite package manager like
> [`uv`](https://github.com/astral-sh/uv),
> [`hatch`](https://github.com/pypa/hatch)
> or [`pdm`](https://github.com/pdm-project/pdm)
> instead of `pip`.

```sh
> pip install noqaexplain
```

### Usage

To check against all files (the ones with defined mappings
from file extension to error disable comment format), run:

```sh
> noqaxplain check
```

You can pass additional arguments to `noqaexplain check`, like files
to check:

```sh
> noqaexplain check path/to/file.py maybe.rs other.yml formats.js
```

If a certain file has a line with disabled check without an explanation,
the tool will report it:

```plaintext
path/to/file.py:10:5: ENQ0 Missing explanation (enoqa) for disabled linting rule
```

to fix it, just add an explanation after the disable comment prefixed by `enq:`,
e.g.:

```python
import some_library
# enq: Disabled private access check as there is no other workaround currently.
# noqa: SLF001
some_library._private_function()
```

## Advanced

### Configuration

You can configure pynudger in `pyproject.toml` (or `.noqaexplain.toml`
in the root of your project, just remove the `[tool.noqaexplain]` section),
for example:

```toml
[tool.noqexplain]
# include rules by their code
include_codes = [0] # default: all rules included
# exclude rules by their code (takes precedence over include)
exclude_codes = [1] # default: no rules excluded
# whether to exit after first error or all errors
end_mode = "first" # default: "all"

# Extends Python noqas mappings
# Now every # my_noqa_header: will be treated as a noqa comment
# and checked for explanations.
extend_suffix_mapping = {".py" = ["# my_noqa_header:"]}
# Target any MySuperFile.md file(s) and look for explanations
extend_name_mapping = {"MySuperFile.md" = ["# my_noqa_header:"]}
```

> [!TIP]
> Rule-specific configuration can be found in the section below.

### Run as a pre-commit hook

`noqaexplain` can be used as a pre-commit hook, to add as a plugin:

```yaml
repos:
-   repo: "https://github.com/open-nudge/noqaexplain"
    rev: ...  # select the tag or revision you want, or run `pre-commit autoupdate`
    hooks:
    -   id: "noqaexplain"
```

### Rules

> [!TIP]
> Run `noqaexplain rules` to see the list of available rules.

`noqaexplain` provides the following rules:

<!-- pyml disable-num-lines 25 line-length-->

| Name   | Description                                                                                         |
| ------ | --------------------------------------------------------------------------------------------------- |
| `NQE0` | Ensures that all disabled linting rules have an associated explanation one line above them          |
| `NQE1` | Ensures that all disabled linting rules have an associated explanation of at least <minimal length> |

and the following configurable options (in `pyproject.toml`
or `.noqaexplain.toml`):

<!-- pyml disable-num-lines 10 line-length-->

| Option                  | Description                                                                            | Affected rules | Default  |
| ----------------------- | -------------------------------------------------------------------------------------- | -------------- | -------- |
| `extend_suffix_mapping` | Additional file suffix to noqa comment(s) format mappings (dict of lists)              | __All__        | `{}`     |
| `extend_name_mapping`   | Additional file name to noqas comment(s) format mappings (dict of lists)               | __All__        | `{}`     |
| `suffix_mapping`        | File suffix to noqa comment format(s) mappings (dict of lists, __overrides default!__) | __All__        | `{}`     |
| `name_mapping`          | File name to noqa comment format(s) mappings (dict of lists, __overrides default!__)   | __All__        | `{}`     |
| `min_explain_length`    | Minimum length of explanation for disabled linting rules                               | NQE1           | 10       |
| `explain_noqa_pattern`  | String identifying explanation for disabled linting rule                               | NQE0           | `"enq:"` |
