# Validation Settings

The `validate` section of the `atmos.yaml` configures EditorConfig validation settings. EditorConfig helps maintain consistent coding styles across different editors and IDEs.

## Configuration

**File:** `atmos.yaml`

```yaml
validate:
  editorconfig:
    # Skip default EditorConfig rules
    ignore_defaults: false

    # Preview mode - show what would be checked without failing
    dry_run: false

    # Output format for validation results
    format: default

    # Custom EditorConfig file paths to use
    config_file_paths: []

    # Patterns to exclude from validation
    exclude:
      - "vendor/**"
      - "node_modules/**"

    # Initialize EditorConfig in the project
    init: false

    # Disable specific checks
    disable_end_of_line: false
    disable_insert_final_newline: false
    disable_indentation: false
    disable_indent_size: false
    disable_max_line_length: false
