2019-05-19lib/ui/ui: use atomic instead of channelSimon Ser
This makes it so an atomic `invalid` value is used instead of an unbuffered channel. When many invalidations kick in, a lot of values were sent to the channel. (Since OnInvalidate's callback can be run in any goroutine, we need to be careful about races here.)
2019-05-19Update internal state and draw from the same goroutineSimon Ser
This commit introduces a new Aerc.Tick function that should be called to refresh the internal state. This in turn makes each AccountView process worker events. The UI goroutine repeatedly refreshes the internal state before drawing a new frame. The reason for this is that many worker messages may need to be processed for a single frame, and drawing the UI is far slower than refreshing the internal state. This has been confirmed in my testing (calling Aerc.Tick only once per frame results in a slower display). Many synchronization code has been removed. We can now write widgets without having to care so much about races. The remaining sync users are: - widgets/spinner: the spinner value is updated from inside an internal goroutine - lib/ui/invalidatable: Invalidate may be called from any goroutine - lib/ui/grid: same - lib/ui/ui: an internal goroutine needs read access to UI.exit - worker/types/worker: Worker.callbacks is used for both worker and UI callbacks The exact goroutine requirements for Drawable have been documented.

2019-05-05lib/ui: fix UI.Exit race conditionSimon Ser
UI.Exit can be accessed from goroutines drawing, goroutines executing commands and goroutines waiting for events.

2018-06-01switch to tcell from termboxMarkus Ongyerth
This is a simple mostly straight forward switch to tcell in favor of termbox. It uses the tcell native api (not the compat layer) but does not make use of most features. Further changes should include moving to tcell's views.TextArea and the general built in widget behaviour instead of the current ad hoc implementation. Regression: Cursor isn't shown in ex-line
