New and noteworthy

Enhanced Matlab support

Thanks to the contributions from Maikel Steneker CPD for Matlab can now parse Matlab programs which use the question mark operator to specify access to class members:

classdef Class1
properties (SetAccess = ?Class2)

CPD also understands now double quoted strings, which are supported since version R2017a of Matlab:

str = "This is a string"

Enhanced C++ support

CPD now supports digit separators in C++ (language module “cpp”). This is a C++14 feature.

Example: auto integer_literal = 1'000'000;

The single quotes can be used to add some structure to large numbers.

CPD also parses raw string literals now correctly (see #1784).

New Rules

  • The new Apex rule FieldNamingConventions (apex-codestyle) checks the naming conventions for field declarations. By default this rule uses the standard Apex naming convention (Camel case), but it can be configured through properties.

  • The new Apex rule FormalParameterNamingConventions (apex-codestyle) checks the naming conventions for formal parameters of methods. By default this rule uses the standard Apex naming convention (Camel case), but it can be configured through properties.

  • The new Apex rule LocalVariableNamingConventions (apex-codestyle) checks the naming conventions for local variable declarations. By default this rule uses the standard Apex naming convention (Camel case), but it can be configured through properties.

  • The new Apex rule PropertyNamingConventions (apex-codestyle) checks the naming conventions for property declarations. By default this rule uses the standard Apex naming convention (Camel case), but it can be configured through properties.

  • The new Java rule UseShortArrayInitializer (java-codestyle) searches for array initialization expressions, which can be written shorter.

Modified Rules

  • The Apex rule ClassNamingConventions (apex-codestyle) can now be configured using various properties for the specific kind of type declarations (e.g. class, interface, enum). As before, this rule uses by default the standard Apex naming convention (Pascal case).

  • The Apex rule MethodNamingConventions (apex-codestyle) can now be configured using various properties to differenciate e.g. static methods and test methods. As before, this rule uses by default the standard Apex naming convention (Camel case).

  • The Java rule FieldNamingConventions (java-codestyle) now by default ignores the field serialPersistentFields. Since this is a field which needs to have this special name, no field naming conventions can be applied here. It is excluded the same way like serialVersionUID via the property exclusions.

  • The Java rule CommentRequired (java-documentation) has a new property serialPersistentFieldsCommentRequired with the default value “Ignored”. This means that from now on comments for the field serialPersistentFields are not required anymore. You can change the property to restore the old behavior.

  • The Java rule ProperLogger (java-errorprone) has two new properties to configure the logger class (e.g. “org.slf4j.Logger”) and the logger name of the special case, when the logger is not static. The name of the static logger variable was already configurable. The new property “loggerClass” allows to use this rule for different logging frameworks. This rule covers all the cases of the now deprecated rule LoggerIsNotStaticFinal.

  • The Java rule CommentDefaultAccessModifier (java-codestyle) now reports also missing comments for top-level classes and annotations, that are package-private.
