Changelog for the threepenny-gui package

0.9.2.0 – Maintenance and snapshot release

• Add support for SSL.

  To start the server as an HTTPS server, use the jsUseSSL field with appropriate parameters. For security reasons, no information is read from the environment in this case.

• Bump dependencies for compatibility with GHC-9.4.

• Bump dependencies for compatibility with GHC-9.2.

0.9.1.0 – Maintenance and snapshot release

• Add support for websockets over SSL.
• Bump dependencies for compatibility with GHC-9.0.

0.9.0.0 – Maintenance and snapshot release

• The events contextmenu, mousedown, mousemove and mouseup now return Double coordinates instead of Ints. This change reflects updates to the underlying browser APIs and the jQuery library. #238

  Users who prefer to keep working with Int coordinates may use the added roundCoordinates compatibility function.

• Bump dependencies to allow aeson 1.5.

0.8.3.2 – Maintenance release

• Bump dependencies for compatibility with GHC-8.10.

0.8.3.1 – Maintenance release

• Bump dependencies for compatibility with GHC-8.8.
• Bump dependencies to allow hashable 1.3.0.0.
• Remove support for GHC 7.6 and 7.8.

0.8.3.0 – Maintenance and snapshot release

• Export keypress event.
• Fix the spelling of the refX and refY SVG attributes. refX and refY are added to Graphics.UI.Threepenny.SVG.Attributes, the old lowercase versions are deprecated.
• Invoke compatibility mode of IE11 for jQuery v3.2.1.
• Compatibility with GHC-8.6.1

0.8.2.4 – Maintenance release

• Remove redundant dependencies on network-uri and network
• Bump dependencies to allow aeson 1.4.0.0
• Exclude websockets 0.12.5.0 from dependencies.

• Compatibility with GHC-8.4.1
• Bump dependencies to allow aeson 1.3.0.0
• Bump dependencies to allow exceptions 0.10.0
• Bump dependencies to allow snap-server 1.1.0.0

0.8.2.2 – Maintenance release

0.8.2.1 — Maintenance release

• Bump dependencies to allow async 2.2
• Fix a compatibility issue with Cabal-2.0

0.8.2.0 — Snapshot release

• Add getCookies function that retrieves the cookies sent with the HTTP request when the browser window connects (to the websocket). #137

• Allow Electron process to be accessed from JavaScript FFI. #200 This means that Threepenny is now more useful when used with the Electron framework, see doc/electron.md for more information on that.

• Bump dependencies to allow file-embed 0.0.10.1

0.8.1.0 — Snapshot release

• Improve documentation and handling of call buffering (CallBufferMode). The default call buffer mode was documented incorrectly, it was BufferRun and is now FlushOften. #163, #191, #192

• Add new default CallBufferMode: FlushOften. This mode is like BufferRun, but will flush the buffer at every onEvent as well, leading to less confusion when using the library in most circumstances. #191

• Add new CallBufferMode: FlushPeriodically. This mode is like BufferRun, but will flush the call buffer every 300ms if nonempty. #192

• Add support for custom DOM events (CustomEvent). #196

• Expose JavaScript FFI functions toJSObject and liftJSWindow in Graphics.UI.Threepenny. This is useful for linking the lifetime of JavaScript objects to the lifetime of Element. #181

• Use jsLog parameter to log exceptions. #185

• Update bundled jQuery to version 3.2.1. #186

0.8.0.1 — Maintenance release

• Bump dependencies for compatibility with GHC-8.2.1
• Bump dependencies to allow websockets 0.12

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 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.

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

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.
