New features in the 2.10 series
Since 2.10.3 is strictly a bug-fix release, here’s an overview of the most prominent new features and improvements as introduced in 2.10.0:
-
Value Classes
-
A class may now extend
AnyVal
to make it behave like a struct type (restrictions apply). -
https://docs3.scala-lang.org/overviews/core/value-classes.html
-
-
Implicit Classes
-
The implicit modifier now also applies to class definitions to reduce the boilerplate of implicit wrappers.
-
-
String Interpolation
-
val what = "awesome"; println(s"string interpolation is ${what.toUpperCase}!")
-
https://docs3.scala-lang.org/overviews/core/string-interpolation.html
-
-
Futures and Promises
-
Asynchronously get some JSON:
for (req <- WS.url(restApiUrl).get()) yield (req.json \ "users").as[List[User]]
(uses play!)
-
-
Dynamic and applyDynamic
-
x.foo
becomesx.applyDynamic("foo")
ifx
’s type does not define afoo
, but is a subtype ofDynamic
-
-
Dependent method types:
def identity(x: AnyRef): x.type = x
// the return type says we return exactly what we got
-
New ByteCode emitter based on ASM
-
Can target JDK 1.5, 1.6 and 1.7
-
Emits 1.6 bytecode by default
-
Old 1.5 backend is deprecated
-
-
A new Pattern Matcher
-
rewritten from scratch to generate more robust code (no more exponential blow-up!)
-
code generation and analyses are now independent (the latter can be turned off with
-Xno-patmat-analysis
)
-
-
Scaladoc Improvements
-
Implicits (-implicits flag)
-
Diagrams (-diagrams flag, requires graphviz)
-
Groups (-groups)
-
-
Modularized Language features
-
Get on top of the advanced Scala features used in your codebase by explicitly importing them.
-
https://docs3.scala-lang.org/sips/modularizing-language-features.html
-
-
Parallel Collections are now configurable with custom thread pools
-
Akka Actors now part of the distribution
- scala.actors have been deprecated and the akka implementation is now included in the distribution.
-
Performance Improvements
-
Faster inliner
-
Range#sum
is now O(1) -
Update of ForkJoin library
-
Fixes in immutable
TreeSet
/TreeMap
-
Improvements to PartialFunctions
-
- Addition of
???
andNotImplementedError
- Addition of
IsTraversableOnce
+IsTraversableLike
type classes for extension methods -
Deprecations and cleanup
-
Floating point and octal literal syntax deprecation
-
Removed scala.dbc
-
Experimental features
-
Scala Reflection
-
Macros
The API is subject to (possibly major) changes in the 2.11.x series, but don’t let that stop you from experimenting with them! A lot of developers have already come up with very cool applications for them. Some examples can be seen at hxxp://scalamacros.org/news/2012/11/05/status-update.html.
A big thank you to all the contributors!
