[Codenarc-user] [ANN] CodeNarc 0.10 and Updated Grails CodeNarc Plugin

[Chris M. <chr...@ea...>]

CodeNarc <http://codenarc.sourceforge.net/>  is a static analysis tool for
Groovy source code. 

 

Version 0.10 includes:

 

Bug Fixes

*	Fix Bug #3071531: "Unused rules don't recognized method closures"
(e.g. return this.&bar;). https://sourceforge.net/tracker/?func=detail
<https://sourceforge.net/tracker/?func=detail&atid=1126573&aid=3071531&group
_id=250145> &atid=1126573&aid=3071531&group_id=250145. 

*	Fix: UnusedPrivateField: Don't produce violation if field is a
Closure field and is invoked. 

*	Fix: ImportFromSamePackage: Causes violations for alias imports
within same package. 

New Rules

*	New UnnecessaryIfStatementRule (basic):  Checks for if statements
where the if and else blocks are only returning true and false constants.
if(x) { return true } else { return false }. 

*	New UnnecessaryBooleanExpressionRule (basic): Check for unnecessary
boolean expressions, including ANDing (&&) or ORing (||) with true, false,
null, or Map/List/String/Number literal. Also checks for negation of true,
false, null, or Map/List/String/Number literal. 

*	New BigDecimalInstantiationRule (basic): Avoid creating BigDecimal
with a decimal (float/double) literal; use a String literal instead. 

*	New UnusedObjectRule (unused): Checks for object allocations that
are not assigned or used. 

*	New UnusedArrayRule (unused): Checks for array allocations that are
not assigned or used. 

*	New ImplementationAsTypeRule (design): Checks that particular
classes are never used as types in variable declarations, return values or
parameters, such as ArrayList, HashSet, Hashtable, PriorityQueue, etc.
(design) 

*	New JUnitUnnecessaryTearDownRule (junit). Checks for tearDown()
methods that only call super.tearDown(). 

*	New JUnitUnnecessarySetUpRule (junit). Checks for setUp() methods
that only call super.setUp().

New Features and Infrastructure

	
*	CodeNarc now requires Groovy 1.6 or later to run. Keep in mind that
it can still run against (analyze) older Groovy code. 

*	New InlineXmlReportWriter (from Robin Bramley) for improved
integration with the Hudson Violations plugin. See
http://wiki.hudson-ci.org/display/HUDSON/Violations. 

*	Upgrade to GMetrics 0.3 for AbcComplexityRule and
CyclomaticComplexityRule. Violations now include line number and source
line. 

*	All JUnit rules (JUnit*Rule): Also apply to classes with names
ending in *TestCase. 

*	Add codenarc create-rule script to create a new rule and associated
classes/tests (from Hamlet D'Arcy). 

*	ConstantTernaryExpressionRule and ConstantIfExpressionRule: Also
flag constant Map and List expressions. 

*	GrailsPublicControllerMethod: add ignoreMethodNames property.

Grails CodeNarc Plugin Updated 

*	The Grails CodeNarc Plugin (  <http://grails.org/plugin/codenarc>
http://grails.org/plugin/codenarc ) has also been updated to version 0. 7,
to upgrade to CodeNarc 0. 10.  Plugin changes include: 


*	
Add support in "Config.groovy" for using a custom "codenarc.properties". Set
an optional property: e.g. codenarc.propertiesFile =
"file:grails-app/conf/codenarc.properties".
