## Examples

```shell
atmos validate editorconfig
atmos validate editorconfig --logs-level Trace
atmos validate editorconfig --no-color
atmos validate editorconfig --dry-run
atmos validate editorconfig --format sarif > editorconfig.sarif

# Source excerpts for local or CI logs
atmos validate editorconfig --format rich
atmos validate editorconfig --ci
atmos validate editorconfig --affected --base origin/main
```

`--affected` checks only files changed since the Git merge-base. Changing an
EditorConfig rule file validates the complete project because the rule can apply
to every file. GitHub Actions automatically uses the pull request base SHA;
use `--base` locally to choose a comparison point.

## Flags

- **`--config` (optional)** — Path to the configuration file (e.g., `.editorconfig`, `.editorconfig-checker.json`, `.ecrc`).
- **`--disable-end-of-line` (optional)** — Disable end-of-line check (default `false`).
- **`--disable-indent-size` (optional)** — Disable indent size check (default `false`).
- **`--disable-indentation` (optional)** — Disable indentation check (default `false`).
- **`--disable-insert-final-newline` (optional)** — Disable final newline check (default `false`).
- **`--disable-max-line-length` (optional)** — Disable max line length check (default `false`).
- **`--disable-trim-trailing-whitespace` (optional)** — Disable trailing whitespace check (default `false`).
- **`--dry-run` (optional)** — Show which files would be checked (default `false`).
- **`--exclude` (optional)** — Regex to exclude files from checking.
- **`--format` (optional)** — Specify the output format: `default`, `gcc`, `codeclimate`, `github-actions`, `sarif`, or `rich` (default `default`). `sarif` and `rich` are rendered by Atmos; the other formats are provided by EditorConfig Checker. The flag overrides `ATMOS_VALIDATE_FORMAT`, which overrides `validate.editorconfig.format`, then `validate.format`, in `atmos.yaml`.
- **`--ci` (optional)** — Enable CI annotations. SARIF is uploaded only when `ci.enabled` and `ci.results.enabled` are enabled in `atmos.yaml`.
- **`--help` (optional)** — help for editorconfig.
- **`--ignore-defaults` (optional)** — Ignore default excludes (default `false`).
- **`--init` (optional)** — Create an initial configuration (default `false`).
- **`--no-color` (optional)** — Don't print colors (default `false`).
- **`--version` (optional)** — Print the version number (default `false`).
