Changelog for the threepenny-gui package

0.8.0.0 — Snapshot release

Graphics.UI.Threepenny

  • Fix getElementById to properly return Nothing when no element with the given id attribute is present. #129.
  • Bring back loadFile and loadDirectory. #110
  • Add MonadUI typeclass for easier lifting in custom monad stacks. #173

JavaScript FFI

  • Implement batching / buffering for FFI calls. #131. Several calls to the runFunction function may now buffer the JavaScript code and send it to the browser window in a single message at a later time. This improves performance considerably.
  • Clarify semantics for exceptions. See the file doc/javascript-ffi.md for more.
    • The UI monad now supports exception handling by being an instance of the type classes MonadThrow and MonadCatch.
    • The function callFunction can now throw a JavaScriptException exception to the Haskell side.
    • The function runFunction now terminates the connection to the browser window whenever the JavaScript code within throws an exception.
  • Exceptions in the UI monad that are not handled are now printed properly for better debugging. #145
  • Clarify semantics of the disconnect event. It is now triggered more reliably. #133.
  • Remove unnecessary client response when exporting event handlers. #131.
  • Add option jsWindowReloadOnDisconnect to reload the browser window #130 whenever the WebSocket connection is broken. This is useful for e.g. mobile devices, which tend to disconnect WebSocket connections very often.

Dependencies

  • Add dependency on exceptions

0.7.0.2 — Maintenance release

  • Bump dependencies to allow aeson 1.2
  • Bump dependencies to allow websockets 0.11

0.7.0.1 — Maintenance release

  • Bump dependencies to allow aeson 1.1
  • Bump dependencies to allow vector 0.12
  • Bump dependencies to allow websockets 0.10

0.7.0.0 — Maintenance and snapshot release

  • JavaScript FFI: Reduce communication from browser to server when creating Elements. New function unsafeCreateJSObject to create JavaScript objects without waiting for a client response. #131
  • JavaScript FFI: Implement escape sequence '%%' when calling JavaScript functions. #132.
  • Change type of onEvent function to allow unregistering events.
  • Add function timestamp for simple performance measurements.
  • Update JavaScript dependencies to jQuery 2.2.3
  • Adapt to GHC 8.0.1. #138
  • Bump dependencies to allow aeson 1.0
  • Bump dependencies to allow data-default 0.7
  • Bump dependencies to allow snap-core 1.0 and snap-server 1.0
  • Bump dependencies to allow template-haskell 2.11
  • Bump dependencies to allow websockets-snap 0.10

0.6.0.6 — Maintenance release

  • Bump dependencies to allow base 4.9
  • Bump dependencies to allow aeson 0.11

0.6.0.5 — Maintenance release

  • Bump dependencies to allow async 2.1
  • Bump dependencies to allow transformers 0.5

0.6.0.4 — Maintenance release.

  • Elements that have become unreachable, for instance because they have been removed from the DOM and are no longer reachable in the Haskell code, will be garbage collected again. Fix #109, #113.
  • Adjust dependencies.
  • Add <meta> tag to indicate UTF8 encoding in html file. #116

0.6.0.3 — Maintenance release.

  • Temporary fix for #109, which was causing event handlers to be discarded. Unfortunately, this means that elements are currently not garbage collected after they have been removed from the DOM tree.

0.6.0.2 — Maintenance release.

  • Remove unused direct dependencies, in particular ** attoparsec-enumerator ** utf8-string ** MonadCatchIO-transformers ** time

0.6.0.1 — Maintenance release.

  • The ADDR environment variable is now parsed correctly.
  • Now builds on GHC 7.8 and GHC 7.10
  • The example source code in the samples folder has been reorganized and consolidated.

0.6.0.0 — Snapshot release.

  • The internals of the JavaScript FFI has been reimplemented completely. A new module Foreign.JavaScript exports a bare JavaScript FFI in case you want to write a custom GUI framework. However, the module Graphics.UI.Threepenny is not compatible with it, even though it builds on top of it.
  • The fields of Config type for server configuration are now prefixed with js instead of tp. Example: jsPort, jsStatic.
  • The functions loadFile and loadDirectory have been removed, as I felt that the jsStatic option is sufficient for most use cases.

0.5.0.0 — Snapshot release.

  • Possibility to specify IP address to bind the server to.
  • FFI now supports callbacks into Haskell. Remove callDeferredFunction function.
  • Graphics.UI.Threepenny.Canvas.SVG for creating SVG elements and attributes.
  • 2D graphics API in Graphics.UI.Threepenny.Canvas is beginning to grow.
  • Bool is now correctly marshalled to JavaScript.
  • Text can now be marshalled to JavaScrtip.

0.4.2.0 — Maintenance release.

  • Dependency bytestring >=0.9.2 is now implemented correctly.
  • Allow newer versions of aeson dependency.
  • Allow newer versions of network, transformers and template-haskell dependencies.
  • Helper scripts in the samples directory now assume that you use a cabal sandbox for development.
  • The UI monad is now an instance of the Applicative class.

0.4.1.0 — Maintenance release.

  • Dependency on text package now from version 0.11 to 1.1.*.
  • Dependency on aeson package replaces the former dependency on the json package.
  • Unicode characters are now transmitted correctly to the browser. #75, #62.
  • Change default port number to 8023. #64

0.4.0.2 — Bugfix release.

  • Fix CSS bug for grid function.

0.4.0.1 — Maintenance release.

  • Adjust package dependencies.

0.4.0.0 — Snapshot release.

  • New UI monad for easier JavaScript FFI and recursion in FRP.
  • Garbage collection for DOM elements. (Unfortunately, this doesn't support using custom HTML files anymore, see issue #60.)
  • First stab at widgets.
  • Bump dependencies to allow websockets 0.8

0.3.0.0 — Snapshot release.

  • Browser communication with WebSockets.
  • First stab at FRP integration.

0.2.0.0 — Snapshot release.

  • First stab at easy JavaScript FFI.

0.1.0.0

  • Initial release.
