All notable changes to this project will be documented in this file.

This projects adheres to Keep a CHANGELOG and uses Semantic Versioning.

1.0.1 - 2023-01-05

Changed

Other

• Composer: The version requirements for the Composer PHPCS plugin have been widened to allow for version 1.0.0. #428 Please ensure you run composer update phpcsstandards/phpcsutils --with-dependencies to benefit from this.
• Removed the references to pre-1.0.0 QA releases from the docs. #425
• Various small housekeeping and maintainance updates. Thanks @szepeviktor for contributing.

1.0.0 - 2023-01-04

For the full list of features, please see the changelogs of the alpha/rc releases:

• 1.0.0-rc1
• 1.0.0-alpha4
• 1.0.0-alpha3
• 1.0.0-alpha2
• 1.0.0-alpha1

Changed

Other

• Minor documentation improvements.
• Maintainability improvements.

1.0.0-rc1 - 2022-12-27

Added

Tokens

• New Collections::constantModifierKeywords() method. #400
• New Collections::listOpenTokensBC() method. #405

Changed

Utils

• ObjectDeclarations::getClassProperties(): the array return value will now include 'abstract_token', 'final_token', and 'readonly_token' indexes identifying the stack pointers to these keyword, where applicable. If the keyword is not used, the value will be set to false. #401

Other

• Various housekeeping and CI maintainance.

Removed

Everything which was previously deprecated in the 1.0.0-alpha4 release, has now been removed. #410

This includes:

• The PHPCS23Utils standard.
• Collections class: direct access to the properties in the class.
• Collections class: the Collections::arrowFunctionTokensBC(), Collections::functionDeclarationTokensBC(), Collections::parameterTypeTokensBC(), Collections::propertyTypeTokensBC() and Collections::returnTypeTokensBC() methods.
• The ControlStructures::getDeclareScopeOpenClose() method.
• The FunctionDeclarations::getArrowFunctionOpenClose() method.
• The FunctionDeclarations::isArrowFunction() method.

See the changelog for the 1.0.0-alpha4 release for details about replacements for the removed functionality.

Fixed

Utils

• Arrays::getOpenClose(): small efficiency fix. #406
• ControlStructures::hasBody(): correctly identify that a control structure does not have a body - 'has_body' = false -, when the control structure is ended by a PHP close tag. #403
• Lists::getOpenClose(): small efficiency fix. #407

1.0.0-alpha4 - 2022-10-25

Notes:

• While still in alpha, some BC-breaks may be introduced. These are clearly indicated in the changelog with the symbol.
• Until PHPCS 4.x has been released, PHPCSUtils does not formally support it, though an effort is made to keep up with the changes and anticipate potential compatibility issues. For testing purposes only, the composer configuration allows for PHPCSUtils to be installed with PHPCS 4.x.

Breaking Changes

Support for PHP_CodeSniffer < 3.7.1 has been dropped after consultation with the principle external standards which depend on PHPCSUtils. #347

This was unfortunately necessary as the incessant additions of new syntaxes since PHP 7.4 made it impossible to continue to support PHPCS < 3.7.1, while still providing reliable results for modern PHP code.

Added

Now support for PHPCS < 3.7.1 has been dropped, this edition adds support to all functionality in PHPCSUtils for new syntaxes and features from PHP 8.0 and 8.1 and preliminary support for PHP 8.2.

This means that support for the following syntaxes/features has been added (or existing support verified/improved):

• PHP 7.4
  • Array unpacking in array expressions.
• PHP 8.0
  • The mixed type. #163
  • Union types, including supporting the false and null types. #168, #225
  • Constructor property promotion. #169, #226
  • Nullsafe object operators. #176, #183
  • Namespaced names as single token (cross-version PHPCS 3.x vs 4.x). #205, #206, #207, #208, #209, #210, #211, #212, #213, #217, #241
  • Dereferencing of interpolated text strings.
  • Named arguments in function calls. #235, #243, #383
  • Match expressions. #247, #335, #356
  • Trailing commas in parameter lists and closure use lists.
  • Attributes. #357
• PHP 8.1
  • Enumerations. #285, #358
  • Explicit octal notation. #293
  • Array unpacking with string keys.
  • never type.
  • Named parameters after argument unpacking. #383
  • First class callables. #362
  • Readonly properties. #363
  • new in initializers.
  • Intersection types. #365
• PHP 8.2
  • Constants in traits. #366
  • Readonly classes. #367
  • true type. #368
  • null and false as stand-alone types.

Please report any bugs/oversights you encounter!

PHPCS Backcompat

• BCTokens::magicConstants() as introduced in PHPCS 3.5.6. #172 The same token array previously already existed in PHPCSUtils as Collections::$magicConstants (which has now been deprecated).

TestUtils

• New UtilityMethodTestCase::usesPhp8NameTokens() method as a helper for tests using token position calculations when testing against both PHPCS 3.x as well as 4.x. #200, #217, #241

Tokens

• New PHPCSUtils\Tokens\TokenHelper class: Utility functions for working with tokens and token collections. #304 This class initially contains a tokenExists() method to work around potential interference from PHP-Parser also backfilling tokens. External standards using a function call to defined() to determine whether a token is available should replace those with a function call to the TokenHelper::tokenExists() method.
• New Collections::arrayOpenTokensBC() method. #233, #311
• New Collections::functionCallTokens() method to retrieve the tokens which can represent function calls and function-call-like language constructs, like class instantiations. #233
• New Collections::nameTokens() method to retrieve the tokens which can be used for “names”, be it namespace, OO, function or constant names. #204, #217
• New Collections::namespacedNameTokens() method to retrieve the tokens which can be encountered in a fully, partially or unqualified name and in namespace relative names. #202, #217
• New Collections::parameterPassingTokens() method to retrieve the tokens which can be passed to the methods in the PassedParameters class. #233
• New Collections::phpOpenTags() method. #254
• New Collections::shortArrayListOpenTokensBC() method. #381

Utils

• New PHPCSUtils\Utils\Context class: Utility functions to determine the context in which an arbitrary token is used. #219. #390 Initial set of available methods: inEmpty(), inIsset(), inUnset(), inAttribute, inForeachCondition() and inForCondition().
• New PHPCSUtils\Utils\MessageHelper class: Utility functions for creating error/warning messages. #249, #391 Initial set of available methods: addMessage(), addFixableMessage(), stringToErrorcode() and showEscapeChars().
• New PHPCSUtils\Utils\PassedParameters::getParameterFromStack() efficiency method to retrieve a potentially named function call parameter from a parameter information stack as previously retrieved via PassedParameters::getParameters(). #235, #237, #383
• New PHPCSUtils\Utils\TextStrings::getEndOfCompleteTextString() method. #320 This method allows to retrieve the stack pointer to the last token within a - potentially multi-line - text string. This method compliments the TextStrings::getCompleteTextString() method which will retrieve the contents of the complete text string.
• New PHPCSUtils\Utils\TextStrings::getEmbeds() method to retrieve an array with all variables/expressions as embedded in a text string. #321
• New PHPCSUtils\Utils\TextStrings::stripEmbeds() method to strip all embedded variables/expressions from a text string. #321
• New PHPCSUtils\Utils\TextStrings::getStripEmbeds() method. #321 This method is public for those rare cases where both the embeds, as well as the text stripped off embeds, is needed.
• New PHPCSUtils\Utils\UseStatements::mergeImportUseStatements() method. #196

Other

• PHPCSUtils will now cache the results of (potentially) token walking intensive or processing intensive function calls during a run. #332, #377 This should significantly improve performance when multiple sniffs call these functions for the same token during a PHPCS run. The results of the following functions will now be cached:
  • Arrays::getDoubleArrowPtr()
  • Arrays::isShortArray()
  • FunctionDeclarations::getParameters()
  • Lists::getAssignments()
  • Lists::isShortList()
  • Namespaces::findNamespacePtr()
  • PassedParameters::getParameters()
  • TextStrings::getEndOfCompleteTextString()
  • TextStrings::getStripEmbeds()
  • UseStatements::splitImportUseStatement()

Changed

PHPCS Backcompat

• All token array methods in the BCTokens class are fully up-to-date with the upstream PHP_CodeSniffer\Util\Tokens properties as per PHPCS master at the time of this release. #327, #347, #360
• All methods in the BCFile class are fully up-to-date with the upstream PHP_CodeSniffer\Files\File methods as per PHPCS master at the time of this release. #347
• BCFile::getMethodParameters(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251
• If a non-existent token array is requested from the BCTokens class, a PHPCSUtils\Exceptions\InvalidTokenArray exception will be thrown. #344 The PHPCSUtils\Exceptions\InvalidTokenArray exception extends the PHPCS native PHP_CodeSniffer\Exceptions\RuntimeException. Previously, an empty array would be returned.

TestUtils

• UtilityMethodTestCase: all properties contained in the test case class will now always be reset after the tests have run. #325
• UtilityMethodTestCase::getTargetToken(): when the target token cannot be found, the method will now throw a (catchable) PHPCSUtils\Exceptions\TestTargetNotFound exception instead of failing the test. #248, #371 If uncaught, this means that the test will be marked as errored instead of failed.
• UtilityMethodTestCase::getTargetToken(): this method is now static, which allows for it to be used in “set up before class” fixtures. #382. #385

Tokens

• Collections::functionCallTokens() and Collections::parameterPassingTokens(): now include the T_PARENT token. #328 This accounts for a change in PHPCS 3.7.0 for how parent in new parent is tokenized.
• If a non-existent token array is requested from the Collections class, a PHPCSUtils\Exceptions\InvalidTokenArray exception will be thrown. #349 The PHPCSUtils\Exceptions\InvalidTokenArray exception extends the PHPCS native PHP_CodeSniffer\Exceptions\RuntimeException.

Utils

• Arrays::isShortArray()/Lists::isShortList(): the underlying logic has been completely refactored for improved accuracy and improved performance. #392
• FunctionDeclarations::getParameters(): the return array of the method may contain two new keys - property_visibility and visibility_token. #169 These keys will only be included if constructor property promotion is detected.
• FunctionDeclarations::getParameters(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251
• GetTokensAsString: previously the tabReplaced() method was an alias for the normal() method. This has now been reversed. #297
• Operators::isReference(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #195
• Parentheses: all methods will now recognize isset(), unset(), empty(), exit(), die() and eval() as parentheses owners. #215 Note: PHPCS natively does not recognize these constructs as parentheses owners, though this may change in the future. See: PHPCS#3118
• PassedParameters: all methods will now recognize anonymous class instantiations as constructs which can pass parameters. #234
• PassedParameters::getParameters(): when a named parameter is encountered in a function call, the returned parameter information array for that parameter will now contain the following additional keys: 'name', 'name_token' and the top-level index for the parameter will be set to the parameter 'name' instead of its position. #235, #243, #383 The existing 'start', 'end', 'raw' and 'clean' keys will contain the same content as before: the information about the parameter value (excluding the name part).
• PassedParameters::getParameters(): new, optional parameter $limit to allow for limiting the number of parameters/array items to be parsed. #261 This allows for higher efficiency when retrieving the parameters/array entries, especially for large arrays if only the first few entries need to be examined. Use with care on function calls, as this can break support for named parameters!
• PassedParameters::getParameters(): new, optional parameter $isShortArray to allow for skipping the “is short array” check for predetermined short arrays. #269, #270 Use judiciously and with extreme care!
• PassedParameters::getParameter(): new semi-optional $paramNames parameter to allow for retrieving a parameter from a function call using named parameters. #235 This parameter is required when examining a function call and an exception will be thrown if it was not passed. This new $paramNames parameter allows for passing either the parameter name as a string or as an array of strings. While a parameter can only have one name, a lot of packages have been, and may still be, reviewing and renaming parameters to more descriptive names to support named parameters in PHP 8.0, so, to allow for supporting multiple versions of packages, different names can be used for the same parameter in a PHP 8.0+ function call and by allowing multiple names to be passed, the method supports this.
• PassedParameters::getParameter(): efficiency improvement applicable to function calls not using named parameters and arrays. #261, #262
• PassedParameters::hasParameters(): now allows for the T_PARENT token for new parent() class instantiations. #328 This accounts for a change in PHPCS 3.7.0 regarding how parent in new parent is tokenized.
• PassedParameters::hasParameters(): new, optional parameter $isShortArray to allow for skipping the “is short array” check for predetermined short arrays. #269, #270 Use judiciously and with extreme care!
• UseStatements::getType(): forward compatibility with PHPCS 4.x in which closure use will be a parenthesis owner. #251

Other

• The master branch has been renamed to stable. #397
• All non-abstract classes in this package are now final. #376
• The parameter names in various function declarations have been changed to not intersect with reserved keywords. #256 In the unlikely event an external standard using PHPCSUtils would be using function calls with named parameters, the parameter names will need to be updated to match.
• Composer: The package will now identify itself as a static analysis tool. Thanks @GaryJones! #341
• Readme/website homepage: the installation instructions have been updated to include information on installing this library and the included Composer PHPCS plugin in combination with Composer >= 2.2. #291, #292
• Various documentation improvements. #216, #309, #394, #395, #396, #398
• Various housekeeping and CI maintainance. Amongst other things, CI is now run via GitHub Actions (#239), the PHPCSUtils native tests now use the PHPUnit Polyfills package (#277) and the tests are now run against PHP 5.4 - 8.2.

Deprecated

Everything which has currently been deprecated, will be removed before the final 1.0.0 version of PHPCSUtils is tagged.

Utils

• ControlStructures::getDeclareScopeOpenClose(): this method is no longer needed, check the scope_opener/scope_closer on the T_DECLARE token instead. #347
• FunctionDeclarations::getArrowFunctionOpenClose(): this method is no longer needed, check the scope_opener/scope_closer etc on the T_FN token instead. #347
• FunctionDeclarations::isArrowFunction(): this method is no longer needed, use the T_FN token instead. #347

Other

• The PHPCS23Utils standard, which is no longer needed now support for PHPCS < 3.7.1 has been dropped. #347

Removed

• Support for PHPCS < 3.7.1. #347

  • PHPCSUtils\Utils\Numbers::REGEX_NUMLIT_STRING
  • PHPCSUtils\Utils\Numbers::REGEX_HEX_NUMLIT_STRING
  • PHPCSUtils\Utils\Numbers::UNSUPPORTED_PHPCS_VERSION

Fixed

Abstract Sniffs

• AbstractArrayDeclarationSniff::getActualArrayKey(): will now handle escaped vars in heredoc array keys better. #379

Fixers

• SpacesFixer: in a specific new line vs trailing comment situation, the fixer would incorrectly add a stray new line. #229

TestUtils

• UtilityMethodTestCase::getTargetToken(): will now throw a PHPCSUtils\Exceptions\TestMarkerNotFound exception if the provided test marker comment is not found. #273, #372 This prevents the method potentially misidentifying the target token.

Tokens

• Collections::parameterTypeTokens(), Collections::propertyTypeTokens() and Collections::returnTypeTokens(): include the namespace keyword for namespace relative identifier names. #180

Utils

• Various housekeeping.

Fixed

Abstract Sniffs

• AbstractArrayDeclarationSniff: improved parse error handling. #99

PHPCS BackCompat

• BCFile::findEndOfStatement(): now supports arrow functions when used as a function argument, in line with the same change made in PHPCS 3.5.5. #143
• BcFile::isReference(): bug fix, the reference operator was not recognized as such for closures declared to return by reference. #160, PHPCS#2977

Changed

PHPCS BackCompat

• BCFile::getCondition(): sync with PHPCS 3.5.4 - added support for new $first parameter. #73

Tokens

• The Collections::$returnTypeTokens property now includes T_ARRAY to allow for supporting arrow functions in PHPCS < 3.5.3. #77

Utils

• Conditions::getCondition(): sync with PHPCS 3.5.4 - renamed the existing $reverse parameter to $first and reversing the meaning of the boolean values, to stay in line with PHPCS itself. #73
• Numbers: the $unsupportedPHPCSVersions property has been replaced with an UNSUPPORTED_PHPCS_VERSION constant. #88

Other

• Various housekeeping.

1.0.0-alpha1 - 2020-01-23

Initial alpha release containing:

• A PHPCS23Utils standard which can be used to allow an external PHPCS standard to be compatible with both PHPCS 2.x as well as 3.x.
• A PHPCSUtils standard which contains generic utilities which can be used when writing sniffs. This standard does not contain any sniffs! To use these utilities in PHPCS 3.x, all that is needed is for this package to be installed and registered with PHPCS using installed_paths. If the package is requested via Composer, this will automatically be handled by the Composer PHPCS plugin. To use these utilities in PHPCS 2.x, make sure the external standard includes the PHPCS23Utils standard in the ruleset.xml file like so: <rule ref="PHPCS23Utils"/>.

All utilities offered are compatible with PHP_CodeSniffer 2.6.0 up to the latest stable release.

This initial alpha release contains the following utility classes:

Abstract Sniffs

• AbstractArrayDeclarationSniff: to examine array declarations.

BackCompat

• BCFile: Backport of the latest versions of PHPCS native utility functions from the PHP_CodeSniffer\Files\File class to make them available in older PHPCS versions without the bugs and other quirks that the older versions of the native functions had.
• BCTokens: Backport of the latest versions of PHPCS native token arrays from the PHP_CodeSniffer\Util\Tokens class to make them available in older PHPCS versions.
• Helper: Utility methods to retrieve (configuration) information from PHP_CodeSniffer 2.x as well as 3.x.

Fixers

• SpacesFixer: Utility to check and, if necessary, fix the whitespace between two tokens.

TestUtils

• UtilityMethodTestCase: Base class for use when testing utility methods for PHP_CodeSniffer. Compatible with both PHPCS 2.x as well as 3.x. Supports PHPUnit 4.x up to 8.x. See the usage instructions in the class docblock.

Tokens

• Collections: Collections of related tokens as often used and needed for sniffs. These are additional “token groups” to compliment the ones available through the PHPCS native PHP_CodeSniffer\Util\Tokens class.
