Comment Syntax Changes

This release deprecates the @codingStandards comment syntax used for sending commands to PHP_CodeSniffer. The existing syntax will continue to work in all version 3 releases, but will be removed in version 4

The comment formats have been replaced by a shorter syntax:

• @codingStandardsIgnoreFile becomes phpcs:ignoreFile
• @codingStandardsIgnoreStart becomes phpcs:disable
• @codingStandardsIgnoreEnd becomes phpcs:enable
• @codingStandardsIgnoreLine becomes phpcs:ignore
• @codingStandardsChangeSetting becomes phpcs:set

The new syntax allows for additional developer comments to be added after a -- separator. This is useful for describing why a code block is being ignored, or why a setting is being changed. E.g., // phpcs:disable -- This code block must be left as-is.

Comments using the new syntax are assigned new comment token types to allow them to be detected:

• phpcs:ignoreFile has the token T_PHPCS_IGNORE_FILE
• phpcs:disable has the token T_PHPCS_DISABLE
• phpcs:enable has the token T_PHPCS_ENABLE
• phpcs:ignore has the token T_PHPCS_IGNORE
• phpcs:set has the token T_PHPCS_SET

Other Changes

• The phpcs:disable and phpcs:ignore comments can now selectively ignore specific sniffs (request #604)
  • E.g., // phpcs:disable Generic.Commenting.Todo.Found for a specific message
  • E.g., // phpcs:disable Generic.Commenting.Todo for a whole sniff
  • E.g., // phpcs:disable Generic.Commenting for a whole category of sniffs
  • E.g., // phpcs:disable Generic for a whole standard
  • Multiple sniff codes can be specified by comma separating them
    • E.g., // phpcs:disable Generic.Commenting.Todo,PSR1.Files
• @codingStandardsIgnoreLine comments now only ignore the following line if they are on a line by themselves
  • If they are at the end of an existing line, they will only ignore the line they are on
  • Stops some lines from accidentally being ignored
  • Same rule applies for the new phpcs:ignore comment syntax
• PSR1.Files.SideEffects now respects the new phpcs:disable comment syntax
  • The sniff will no longer check any code that is between phpcs:disable and phpcs:enable comments
  • The sniff does not support phpcs:ignore; you must wrap code structures with disable/enable comments
  • Previously, there was no way to have this sniff ignore parts of a file
• Fixed a problem where PHPCS would sometimes hang waiting for STDIN, or read incomplete versions of large files
  • Thanks to Arne Jørgensen for the patch
• Array properties specified in ruleset files now have their keys and values trimmed
  • This saves having to do this in individual sniffs and stops errors introduced by whitespace in rulesets
  • Thanks to Juliette Reinders Folmer for the patch
• Added phpcs.xsd to allow validation of ruleset XML files
  • Thanks to Renaat De Muynck for the contribution
• File paths specified using --stdin-path can now point to fake file locations (request #1488)
  • Previously, STDIN files using fake file paths were excluded from checking
• Setting an empty basepath (--basepath=) on the CLI will now clear a basepath set directly in a ruleset
  • Thanks to Xaver Loppenstedt for the patch
• Ignore patterns are now checked on symlink target paths instead of symlink source paths
  • Restores previous behaviour of this feature
• Metrics were being double counted when multiple sniffs were recording the same metric
• Added support for bash process substitution
  • Thanks to Scott Dutton for the contribution
• Files included in the cache file code hash are now sorted to aid in cache file reuse across servers
• Windows BAT files can now be used outside a PEAR install
  • You must have the path to PHP set in your PATH environment variable
  • Thanks to Joris Debonnet for the patch
• The JS unsigned right shift assignment operator is now properly classified as an assignment operator
  • Thanks to Juliette Reinders Folmer for the patch
• The AbstractVariableSniff abstract sniff now supports anonymous classes and nested functions
  • Also fixes an issue with Squiz.Scope.MemberVarScope where member vars of anonymous classes were not being checked
• Added AbstractArraySniff to make it easier to create sniffs that check array formatting
  • Allows for checking of single and multi line arrays easily
  • Provides a parsed structure of the array including positions of keys, values, and double arrows
• Added Generic.Arrays.ArrayIndent to enforce a single tab stop indent for array keys in multi-line arrays
  • Also ensures the close brace is on a new line and indented to the same level as the original statement
  • Allows for the indent size to be set using an indent property of the sniff
• Added Generic.PHP.DiscourageGoto to warn about the use of the GOTO language construct
  • Thanks to Juliette Reinders Folmer for the contribution
• Generic.Debug.ClosureLinter was not running the gjslint command
  • Thanks to Michał Bundyra for the patch
• Generic.WhiteSpace.DisallowSpaceIndent now fixes space indents in multi-line block comments
  • Thanks to Juliette Reinders Folmer for the patch
• Generic.WhiteSpace.DisallowSpaceIndent now fixes mixed space/tab indents more accurately
  • Thanks to Juliette Reinders Folmer for the patch
• Generic.WhiteSpace.DisallowTabIndent now fixes tab indents in multi-line block comments
  • Thanks to Juliette Reinders Folmer for the patch
• PEAR.Functions.FunctionDeclaration no longer errors when a function declaration is the first content in a JS file
  • Thanks to Juliette Reinders Folmer for the patch
• PEAR.Functions.FunctionCallSignature now requires the function name to be indented to an exact tab stop
  • If the function name is not the start of the statement, the opening statement must be indented correctly instead
  • Added a new fixable error code PEAR.Functions.FunctionCallSignature.OpeningIndent for this error
• Squiz.Functions.FunctionDeclarationArgumentSpacing is no longer confused about comments in function declarations
  • Thanks to Juliette Reinders Folmer for the patch
• Squiz.PHP.NonExecutableCode error messages now indicate which line the code block ending is on
  • Makes it easier to identify where the code block exited or returned
  • Thanks to Juliette Reinders Folmer for the patch

• Squiz.Commenting.FunctionCommentThrowTag no longer assigns throw tags inside anon classes to the enclosing function
• Squiz.WhiteSpace.SemicolonSpacing now ignores semicolons used for empty statements inside FOR conditions
  • Thanks to Juliette Reinders Folmer for the patch

  • Override the requiredSpacesBeforeColon setting in a ruleset.xml file to change
  • Default remains at 1
  • Thanks to Nikola Kovacs for the patch
• The Squiz standard now ensures array keys are indented 4 spaces from the main statement
  • Previously, this standard aligned keys 1 space from the start of the array keyword
• The Squiz standard now ensures array end braces are aligned with the main statement
  • Previously, this standard aligned the close brace with the start of the array keyword
• The standard for PHP_CodeSniffer itself now enforces short array syntax
• The standard for PHP_CodeSniffer itself now uses the Generic.Arrays/ArrayIndent sniff rules
• Improved fixer conflicts and syntax error handling for a number of sniffs
