* Fix crash on mouse scrolling before messages loadWiktor Kwapisiewicz2020-02-221-2/+6
| | | | | Using mouse scroll before messages load will trigger a panic as `ml.store` has not been assigned yet and is `nil`.
* config: Strongly type context typeReto Brunner2020-01-241-1/+1
| | | | | | | | The go compiler can't help much with untyped int constants. Even though the only valid constants are 0-3 it will happily accept 4 as input. Let's let the go compiler worry about correctness here. This also allows people not very familiar with the code to use it properly via auto completion.
* Contextual UI ConfigurationSrivathsan Murali2020-01-241-3/+9
| | | | | | | | | + Adds parsing of contextual ui sections to aerc config. + Add GetUiConfig method for AercConfig that is used to get the specialized UI config. + Add UiConfig method to AccountView to get specialized UI Config. + Modifies Aerc codebase to use specialized UIConfig instead. + Adds documentation for Contextual UI Configuration
* msglist: highlight marked messagesReto Brunner2019-12-211-1/+1
| | | | | | Note that, until we get color configuration, this means that the user *must* have the %Z verb in the index format else it'll be horribly confusing as no visual indication is provided
* Complete the F rune.Srivathsan Murali2019-11-171-0/+1
| | | | | %F now shows the auth name or recepient name/address if the message is from you.
* Revert "Show spinner when fetching contents"Drew DeVault2019-10-091-3/+0
| | | | This reverts commit 1339faf7881f33762c6e0a4915404e362fc51de1.
* Show spinner when fetching contentsJeffas2019-10-091-0/+3
| | | | | The spinner should be shown when fetching the contents as we don't know at that point whether there are some messages or not.
* Revert "Fix out-of-order messages by sorting as we display"Drew DeVault2019-09-181-31/+0
| | | | This reverts commit ac99d9ed62644cf0259bdd79481b28c3fbcef650.
* Add MouseableJeffas2019-09-111-1/+44
| | | | | | | | | | | | | | | | | | | | | | This adds the Mouseable interface. When this is implemented for a component that item can accept and process mouseevents. At the top level when a mouse event is received it is passed to the grid's handler and then it trickles down until it reaches a component that can actually handle it, such as the tablist, dirlist or msglist. A mouse event is passed so that components can handle other things such as scrolling with the mousewheel. The components themselves then perform the necessary actions. Clicking emails in the messagelist opens them in a new tab. Textinputs can be clicked to position the cursor inside them. Mouseevents are not forwarded to the terminal at the moment. Elements which do not handle mouse events are not required to implement the Mouseable interface.

* Use sort.Stable for sorting displayed messagesa3v2019-09-021-1/+1
| | | | | With sort.Sort, sometimes two messages with the same timestamp will switch places every time the message list is redrawn
* Allow custom spinner via config filePaul Spooren2019-08-301-1/+1
| | | | | | | | | | | 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>
* Fix out-of-order messages by sorting as we displayStephen Brennan2019-08-291-0/+31
| | | | | | | | | | Sometimes I observe out-of-order messages when using a maildir inbox. It appears that the UIDs for these messages are returned out of order by the MessageStore. In order for a maildir MessageStore to return messages in most recently received order, it must have already opened all messages and parsed the date to use as a sort key. Rather than implement that, simply sort messages by time as we display. This fix shows my emails in order.
* msglist: add initialization stateReto Brunner2019-08-021-15/+31
| | | | | | | | | Make the msglist aware of whether we are still initializing or not. We never stopped spinning the msglist if we didn't get any Directories back from types.ListDirectories. With this change, we can set the init state from the account and display the spinner only if we don't know whether we have directories or not and else the "no messages" string from the config.
* Add new-email triggerJeffas2019-07-261-1/+4
| | | | | | | | | | | | | | | | | This patch sets up the trigger config section of aerc.conf. Each trigger has its own function which is called from the place where it is triggered. Currently only the new-email trigger is implemented. The triggers make use of format strings. For instance, in the new-email trigger this allows the user to select the trigger command and also the information extracted from the command and placed into their command. To actually execute the trigger commands the keypresses are simulated. Further triggers can be implemented in the future. Formatting of the command is moved to a new package.

* Factor IMAP-specific structs out of UI modelsBen Burwell2019-07-081-2/+1
| | | | | | | Before, we were using several IMAP-specific concepts to represent information being displayed in the UI. Factor these structures out of the IMAP package to make it easier for other backends to provide the required information.
* Factor UI models out of the worker message packageBen Burwell2019-07-081-2/+2
| | | | | | | | Before, the information needed to display different parts of the UI was tightly coupled to the specific messages being sent back and forth to the backend worker. Separating out a models package allows us to be more specific about exactly what a backend is able to and required to provide for the UI.

* Update internal state and draw from the same goroutineSimon Ser2019-05-191-21/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lib/msgstore: protect with a mutexSimon Ser2019-04-291-0/+18
| | | | | | MessageStore has a lot of exported fields that can be read from the outside. Each read must be protected, because a call from Update could happen at any time.
* widgets/msglist: fix MessageList.store raceSimon Ser2019-04-291-23/+32
| | | | | This field could be written to in the middle of a Draw call, which reads it multiple times. Use an atomic variable instead.
* lib/ui: introduce InvalidatableSimon Ser2019-04-271-15/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | When changing to an empty directory, ml.selected is 0, and the length of ml.store.Uids is 0. The loop condition is always true so we have an infinite loop causing 100% CPU usage and prevents us to change to other directories. Signed-off-by: Tom Lebreux <tomlebreux@cock.li>
