undone 0.2.4

A library for undo and redo.

Undone Changes

0.2.4

• Updated to SDK 0.5.13_r23552.
• Switched states stream to use the new StreamController.broadcast that was re-introduced in this SDK version. With this change the Schedule is no longer responsible for checking the paused state (a broadcast stream controller is never considered paused) before adding events to the stream; each subscription will buffer events itself when paused.
• Added Future<String> wait(String state) method to Schedule and updated the tests to use this instead of their former utility function equivalent; the motivation for this is that I have other use cases for this function now outside of testing.

0.2.3

• Updated to SDK 0.5.11_r23200.
• Added mirrors.dart library with a SetField action; this is a separate library so that users conciously import it and its dependency on dart:mirrors.

0.2.2

• Updated to SDK 0.5.7_r22611.
• Handle the change to Completer behavior; they are now completed asynchronously by default. A schedule will now flush pending actions at the end of the series of asynchronous events trigerred by its completers, making it more bulletproof.

0.2.1

• Updated to SDK 0.5.3_r22223.
• Avoid streaming states events unless there is a listener and the stream is not paused. This avoids potential memory leaks that might arise with buffered events.

0.2.0

• Updated to SDK 0.5.0_r21823.

0.1.8

• Updated to SDK 0.4.7_r21548.

0.1.7

• Updated to SDK 0.4.4_r20810.
• Switched to using assert for dead code removal of logging code instead of a const bool; the old mechanism required users to modify the library code to enable logging, which was not ideal. Now, logging will be enabled in 'checked' mode and it will be stripped in 'production' mode.

0.1.6

• Changed the type of Schedule.states to Stream<String> and states are now enumerated as static const String.

0.1.5

• Added logging code to the library; default disabled for dead code elimination.
• Fixed a number of bugs.
• Removed the Timer-based wait utility function from the tests.

0.1.4

• Added timeoutMs to wait test utility function; drone.io was hanging since the new SDK (0.4.3_r20444) so this was added to try and catch the error but now the error is not reproducing. This should catch future test hangs.

0.1.3

• Updated to SDK 0.4.3_r20444.

0.1.2

• Added a link to an article in the README.

0.1.1

• Added documentation link to pubspec.

0.1.0

• README and dartdoc improvements.

0.0.4

• README improvements.

0.0.3

• Updated to SDK 0.4.2_r20259.
• Moved unittest to dev_dependencies.
• Bug fix: continuations on undo(), redo(), to() are now called before we flush pending actions; this ensures continuations see things as a result of the operation they are chained to.

0.0.2

• Added homepage to pubspec.

0.0.1

• Initial release.
