- id - equals.hash.code
- description - Check that if a class implements either equals or hashCode, it should implement the other
- class - org.scalastyle.scalariform.EqualsHashCodeChecker
- default level - WarningLevel
No parameters
TBD
- id - for.brace
- description - Checks that braces are used in for comprehensions
- class - org.scalastyle.scalariform.ForBraceChecker
- default level - WarningLevel
Usage of braces (rather than parentheses) within a for comprehension mean that you don't have to specify a semi-colon at the end of every line:
for { // braces
t <- List(1,2,3)
if (i % 2 == 0)
} yield t
is preferred to
for ( // parentheses
t <- List(1,2,3);
if (i % 2 == 0)
) yield t
To fix it, replace the () with {}. And then remove the ; at the end of the lines.
No parameters
<check enabled="true" class="org.scalastyle.scalariform.ForBraceChecker" level="warning"/>
- id - if.brace
- description - Checks that if statement have braces
- class - org.scalastyle.scalariform.IfBraceChecker

org.scalastyle.scalariform.IllegalImportsChecker - Check that a class does not import certain classes

| Parameter | Description | Type | Default Value |
|---|---|---|---|
| illegalImports | Illegal Imports | string | sun._,java.awt._ |
TBD
org.scalastyle.scalariform.ImportGroupingChecker - Checks that imports are grouped together, not throughout the file
- id - import.grouping
- description - Checks that imports are grouped together, not throughout the file
- class - org.scalastyle.scalariform.ImportGroupingChecker

If imports are spread throughout the file, knowing what is in scope at any one place can be difficult to work out.
No parameters
<check enabled="true" class="org.scalastyle.scalariform.ImportGroupingChecker" level="warning"/>
org.scalastyle.scalariform.LowercasePatternMatchChecker - Checks that a case statement pattern match is not lower case, as this can cause confusion
- id - lowercase.pattern.match
- description - Checks that a case statement pattern match is not lower case, as this can cause confusion
- class - org.scalastyle.scalariform.LowercasePatternMatchChecker
- default level - WarningLevel
A lower case pattern match clause with no other tokens is the same as _; this is not true for patterns which start with an upper case letter. This can cause confusion, and may not be what was intended:
val foo = "foo"
val Bar = "bar"
"bar" match { case Bar => "we got bar" } // result = "we got bar"
"bar" match { case foo => "we got foo" } // result = "we got foo"
"bar" match { case `foo` => "we got foo" } // result = MatchError
This checker raises a warning with the second match. To fix it, use an identifier which starts with an upper case letter (best), use case _ or,
if you wish to refer to the value, add a type : Any
val lc = "lc"
"something" match { case lc: Any => "lc" } // result = "lc"
"something" match { case _ => "lc" } // result = "lc"
No parameters
<check enabled="true" class="org.scalastyle.scalariform.LowercasePatternMatchChecker" level="warning"/>
- id - magic.number
- description - Checks for use of magic numbers
- class - org.scalastyle.scalariform.MagicNumberChecker
- default level - WarningLevel
Replacing a magic number with a named constant can make code easier to read and understand, and can avoid some subtle bugs.
A simple assignment to a val is not considered to be a magic number, for example:
val foo = 4
is not a magic number, but
var foo = 4
is considered to be a magic number.
| Parameter | Description | Type | Default Value |
|---|---|---|---|
| ignore | Ignore | string | -1,0,1,2 |
<check enabled="true" class="org.scalastyle.scalariform.MagicNumberChecker" level="warning"> <parameters> <parameter name="ignore">-1,0,1,2,3</parameter> </parameters> </check>
- id - method.length

Long methods can be hard to read and understand.
| Parameter | Description | Type | Default Value |
|---|---|---|---|

- id - method.name
- description - Check that method names match a regular expression
- class - org.scalastyle.scalariform.MethodNamesChecker

| Parameter | Description | Type | Default Value |
|---|---|---|---|
| regex | Regular expression | string | ^[a-z][A-Za-z0-9]*(_=)?$ |
| ignoreRegex | Regular expression to ignore | string | ^$ |

<check enabled="true" class="org.scalastyle.scalariform.MethodNamesChecker" level="warning"> <parameters> <parameter name="regex">^[A-Za-z]*$</parameter> <parameter name="ignoreRegex">^.*$</parameter> <parameter name="ignoreOverride">false</parameter> </parameters> </check>
org.scalastyle.scalariform.MultipleStringLiteralsChecker - Checks that a string literal does not appear multiple times
- id - multiple.string.literals
- description - Checks that a string literal does not appear multiple times
- class - org.scalastyle.scalariform.MultipleStringLiteralsChecker
- default level - WarningLevel
Code duplication makes maintenance more difficult, so it can be better to replace the multiple occurrences with a constant.
| Parameter | Description | Type | Default Value |
|---|---|---|---|
| allowed | Maximum occurences allowed | integer | 1 |
| ignoreRegex | Ignore regular expression | string | ^""$ |
<check enabled="true" class="org.scalastyle.scalariform.MultipleStringLiteralsChecker" level="warning"> <parameters> <parameter name="allowed">1</parameter> <parameter name="ignoreRegex">^\"\"$</parameter> </parameters> </check>

TBD
- id - procedure.declaration
- description - Use a : Unit = for procedure declarations
- class - org.scalastyle.scalariform.ProcedureDeclarationChecker
- default level - WarningLevel
A procedure style declaration can cause confusion - the developer may have simply forgotten to add a '=', and now their method returns Unit rather than the inferred type:
def foo() { println("hello"); 5 }
def foo() = { println("hello"); 5 }
This checker raises a warning with the first line. To fix it, use an explicit return type, or add a '=' before the body.
No parameters
<check enabled="true" class="org.scalastyle.scalariform.ProcedureDeclarationChecker" level="warning"/>
org.scalastyle.scalariform.PublicMethodsHaveTypeChecker - Check that a method has an explicit return type, it is not inferred

- description - Check that a method has an explicit return type, it is not inferred
- class - org.scalastyle.scalariform.PublicMethodsHaveTypeChecker

A public method declared on a type is effectively an API declaration. Explicitly declaring a return type means that other code which depends on that type won't break unexpectedly.
| Parameter | Description | Type | Default Value |
|---|---|---|---|
| ignoreOverride | Ignore overridden methods | boolean | false |
<check enabled="true" class="org.scalastyle.scalariform.PublicMethodsHaveTypeChecker" level="warning"> <parameters> <parameter name="ignoreOverride">false</parameter> </parameters> </check>
