lift-ng 0.5.1


#scala @liftweb @angularjs

  • Corrected a bug exposed by 2-way binding that our early-arrival mechanism to not work if angular.js files are specified at the end of the HTML.
  • Made it possible to add binding actors in the HTML templates without introducing an extra element. Thanks to Antonio for the suggestion!

lift-ng 0.5.0


#scala @liftweb @angularjs

  • Implemented 2-way client/server model binding.
  • Added support for Scala 2.11 against Lift editions 2.6 and 3.0.

What Is Client-Server Binding?

Just as Angular provides declarative 2-way binding between the model and view with automatic synchronization, lift-ng features (a rather experimental) 2-way binding of a model between the client and server. Any changes made on the server are reflected in the client, and vice versa. See the README for more details.


The reduce the network overhead, changes to a bound model on the server will be communicated to the client by sending only a diff. Since watching scope variables on the client can produce a flood of changes (e.g. each character entered in a text box will generate a change event), changes are queued up and sent after no more changes are detected for 1000 millis. The fourth argument to the SimpleBindingActor constructor or an override of clientSendDelay in BindingActor allows you to tweak this delay to your liking.


Note that this feature will utilize more memory than others, paricularly on the server. We maintain the last known state of your model. This allows us to compare to any model changes provided and transmit only the diff from the server.

Currently the client sends the entire model back to the server on change. Soon we hope to support sending only the diff just like we do when sending from the server.

Arrays are not correctly supported yet. A client-side change to an array will append to the array on the server rather than replacing the respective values based on the index.

Removing stuff from a model on the server does not transmit to the client yet. Only changes or additions to the model will be synced up to the client.

Only 2-way binding is currently supported.

Only session-scoped binding is currently supported. That is, a model bound will be reflected on every page load for a given session.

kiama 1.7.0

The Kiama team is pleased to bring you the next release of the library. This release has significant enhancements in the pretty-printing library, but is otherwise a minor release. The release is cross-published for both Scala 2.10 and 2.11.


  • Output

    • The pretty-printing library now has combinators for side-by-side pretty-printing based on similar features of Haskell libraries. Specifically, column and nesting allow pretty-printing documents to depend on the current printing column and nesting level, respectively. Built on these basic combinators are: align which sets the indentation for a nested document to the current column, hang and indent which allow fine-tuning of indentation, width which allows the pretty-printing of a document to depend on the width of another document, and padto/padtobreak which can be used to pad a document to a specific width. <%> and <%%> allow alignment to be used as an operator.
  • Rewriting

    • The dup operation that is used to duplicate nodes during rewriting is more helpful when it fails by mentioning the common problem that rewritten classes cannot be nested inside another class.


  • Utilities

    • ParserUtilities: the regexnows method has been removed to avoid duplication of code from the parser combinators library. We are exploring ways to better support whitespace processing in that library instead.


  • Utilities

    • ParenPrettyPrinter: fixed doc of noparens method
    • REPL: fixed bug where an empty line of input caused REPL to exit
    • Kiama-specific command-line options are now all under --K so that user programs can use other letters for their purposes. E.g., the option to specify that console input should come from a string is --KConsole instead of -c and --console. Run a Kiama main program with --help to see the options.
  • Examples

    • Minor fixes and documentation improvements in Lambda2, MiniJava, Obr and Prolog examples


  • Move to sbt 0.13.5, Scala 2.10.4/2.11.2, Scala parser combinators 1.0.2, ScalaTest 2.2.0, JLine 2.12

Kiama is a Scala library for language processing including attribute grammars, term rewriting, abstract state machines and pretty printing.

unfiltered 0.8.1

This release includes a refactoring of Jetty and Netty server builders (pull request #242). The new builders use immutable configuration objects and are more extensible. The old builders have been deprecated.

Migration in many cases is simply changing to the new Server constructors. Most of the old builder methods exist on the new builders, although notably filter and handler are deprecated in favor of plan.

Some examples:

// listen to http on port 8080, all network interfaces

// listen to http on port 8080, local network interfaces

// listen to http on some available port, local interfaces

// listen to http on 80, https on 443, all interfaces
  keyStorePath=myKeyStorePath, keyStorePassword=myKeyStorePassword

// run a *netty* http server on 80, all interfaces


Other improvements include:

  • Get rid of the multiple close problem and remove some overhead #195
  • Avoid reflective calls (and scalac’s warnings about them) #216
  • Send a LastHttpContent marker after a ChunkedStream #219
  • compare last modified times using 1 second resolution #220
  • Resource leak and keep alive fixes for netty #222
  • Flush out HTTP headers for 304 responses #228
  • Support X-Forwarded-Proto and X-Forwarded-Port #235
  • Cycle and async plans should push websocket frames through the pipeline #237
  • Add an andThen alias for the ~> method of ResponseFunction #241
  • Scalatest 2.2.0 + updated module #243

Unfiltered is a toolkit for servicing HTTP requests in Scala.
