* split: close split on update of split viewTim Culverhouse2022-12-271-0/+3
| | | | | | | | | | | Commit 6b8e0b19d35a ("split: refactor to prevent stuck splits") introduced a regression where a split message viewer is not closed when a new message is selected, leading to every split view staying open in the background.

* split: refactor to prevent stuck splitsTim Culverhouse2022-12-252-93/+45
| | | | | | | | | | Refactor split logic (again...) to prevent stuck splits. Use callback from msgstore.Select to tell the split which message to display. This keeps the account from having to track displayed messages, which prevents race conditions in certain situations.

* style: make marked more important than searchBence Ferdinandy2022-12-141-5/+4
| | | | | | | | | | Currently it's not possible to define combinations of marked and searched.

* split: refactor split update logicTim Culverhouse2022-12-142-29/+41
| | | | | | | | | | | | | | | | | | | | | | Refactor split update logic to more simply update the split. Through the evolution of the split logic, additional variables were stored within the account which allows for cleaner updating of the split. Compare selected UID instead of pointer to message when deciding not to update split. Allow splits to be created and closed when no message is selected. The split will be filled with a ui.Fill (blank). The user will only see a border at the split location when no message is selected. Rename clearSplit to closeSplit, as it is only used in the case when the user doesn't want a split anymore. Ensure that the selected UID is reset to the magic UID when there are no messages left in the message store.

* config: make various sections accessible via global varsRobin Jarry2022-12-1410-198/+168
| | | | | | | | | | | | | | | | | | | | There is only one instance of AercConfig which is associated to the Aerc widget. Everywhere we need to access configuration options, we need somehow to get a reference either to the Aerc widget or to a pointer to the AercConfig instance. This makes the code cluttered. Remove the AercConfig structure and every place where it is referenced. Instead, declare global variables for every configuration section and access them directly from the `config` module. Since bindings and ui sections can be "contextual" (i.e. per account, per folder or per subject), leave most local references intact. Replacing them with config.{Ui,Binds}.For{Account,Folder,Subject} would make this patch even more unreadable. This is something that may be addressed in the future.

* config: rework contextual sections implementationRobin Jarry2022-12-146-49/+18
| | | | | | | | | | | | | The current contextual binds and ui config API is awkward and cumbersome to use. Rework it to make it more elegant. Store the contextual sections as private fields of the UIConfig and KeyBindings structures. Add cache to avoid recomputation of the composed UIConfig and KeyBindings objects every time a contextual item is requested. Replace the cache from DirectoryList with that.

* compose: allow writing multipart/alternative messagesRobin Jarry2022-12-071-1/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new :multipart command that can be executed on the composer review screen. This command takes a MIME type as argument which needs to match a setting in the new [multipart-converters] section of aerc.conf. A part can be removed by using the -d flag. The [multipart-converters] section has MIME types associated with commands. These commands are executed with sh -c every time the main email body is updated to generate each part content. The commands are expected to output valid UTF-8 text. If a command fails, an explicit error will be printed next to the part MIME type to allow users to debug their issue but the email may still be sent anyway with an empty alternative part. This is mostly intended for people who *really* need to send html messages for their boss or for corporate reasons. For now, it is a manual and explicit action to convert a message in such a way. Here is an example configuration: [multipart-converters] text/html = pandoc -f markdown -t html And the associated binding to append an HTML alternative to a message: [compose::review] H = :multipart text/html<enter> hh = :multipart -d text/html<enter> Link: https://lists.sr.ht/~rjarry/aerc-discuss/%3CCO5KH4W57XNB.2PZLR1CNFK22H%40mashenka%3E Co-authored-by: Eric McConville <emcconville@emcconville.com> Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Bence Ferdinandy <bence@ferdinandy.com> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

MessageViews were previously prevented from opening if the error field was not nil, however the addition of message view splits have allowed these messages to have split views created. A panic can occur if a split is open and one of these messages is scrolled over. Prevent access to MessageInfo methods if the Error field is set. Display the error to the user in the split view. The partSwitcher will be nil if an error is set: check for this condition before calling it's methods.
