* Add modify-labels commandReto Brunner2019-09-121-3/+3
| | | | | This adds the event type as well as the command implementation, but no backend supports it yet.
* Allow custom spinner via config filePaul Spooren2019-08-301-19/+10
| | | | | | | | | | | Allows to set `ui.spinner=` to a string which is then split by `ui.spinner-delimiter=` (Default: comma) instead of having a hard coded animation. This implementation doesn't use INIs capabilities to split strings as it trims whitespaces breaking the default animation. Signed-off-by: Paul Spooren <mail@aparcar.org>

* lib/ui: introduce InvalidatableSimon Ser2019-04-271-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many Drawable implementations have their own Invalidate and OnInvalidate functions, with an unexported onInvalidate field. However OnInvalidate and Invalidate are usually not called in the same goroutine. This results in a race on this field, e.g.: Read at 0x00c000094748 by goroutine 7: git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList.func1() /home/simon/src/aerc2/widgets/dirlist.go:85 +0x56 git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start.func1() /home/simon/src/aerc2/widgets/spinner.go:93 +0x1bb Previous write at 0x00c000094748 by main goroutine: [failed to restore the stack] Goroutine 7 (running) created at: git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start() /home/simon/src/aerc2/widgets/spinner.go:46 +0x8f git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList() /home/simon/src/aerc2/widgets/dirlist.go:37 +0x286 git.sr.ht/~sircmpwn/aerc2/widgets.NewAccountView() /home/simon/src/aerc2/widgets/account.go:50 +0x5ca git.sr.ht/~sircmpwn/aerc2/widgets.NewAerc() /home/simon/src/aerc2/widgets/aerc.go:60 +0x800 main.main() /home/simon/src/aerc2/aerc.go:65 +0x33e To fix this, introduce a new type, Invalidatable, which protects the field. Unfortunately the Drawable must be passed to the callback function in Invalidate, so we still need to re-implement this in each Invalidatable user.
* widgets/spinner: fix Spinner.frame raceSimon Ser2019-04-271-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | It's accessed by the goroutine which increments it and the goroutine that draws the widget at the same time. Use atomic instead.
