class ScopeIndentSniff in Coder 8.2

Same name and namespace in other branches
  1. 8.3 coder_sniffer/Drupal/Sniffs/WhiteSpace/ScopeIndentSniff.php \Drupal\Sniffs\WhiteSpace\ScopeIndentSniff
  2. 8.3.x coder_sniffer/Drupal/Sniffs/WhiteSpace/ScopeIndentSniff.php \Drupal\Sniffs\WhiteSpace\ScopeIndentSniff

Largely copied from \PHP_CodeSniffer\Standards\Generic\Sniffs\WhiteSpace\ScopeIndentSniff, modified to make the exact mode working with comments and multi line statements.

Checks that control structures are structured correctly, and their content is indented correctly. This sniff will throw errors if tabs are used for indentation rather than spaces.
