* templates: use template interface consistentlyKoni Marti2023-05-1610-73/+147
| | | | | | | | | | | | | | | Use the template interface consistently. Before, we have exported the state.TemplateData struct and used it in most places instead of the models.TemplateData interface. This lead to some inconsistencies, i.e. Role() has been defined on the exported struct but not on the interface. Unexport the state.TemplateData struct, add a DataSetter interface to set the data needed for the template data and call the Data() method which returns a models.TemplateData interface when the template data is needed.

* headers: enable partial header fetchingTim Culverhouse2023-05-1610-5/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable partial header fetching by creating config values for headers to specifically include, or specifically exclude. The References field will always be fetched, regardless of the include list. Envelope data is always fetched, but is not shown with :toggle-headers, since it isn't in the RFC822 struct unless explicitly included in the list. Partial headers can break the cache on changes. Update the cache tag key to include the state of the partially-fetched headers. Partial header fetching can have a significant performance increase for IMAP, and for all backends a resource improvement. Some data to support this is below. Gathered by opening aerc, selecting a mailbox with approximately 800 messages and scrolling to the end.

* imap: handle the NonExistent attributeKoni Marti2023-05-161-1/+4
| | | | | | | | | | | | | | | | | | Treat the "\NonExistent" attribute similar to the "\NoSelect" one. Only list folders without the "\NonExistent" or "\NoSelect" attribute. According to RFC 9501, section 7.3.1, the "\NonExistent" attribute implies "\NoSelect". When using the LIST-STATUS extension, some servers return a "\NonExistent" flag instead of the "\NoSelect" one. We only check for the "\NoSelect" attribute, and hence, a "\NonExistent" folder will appear in the directory list and raise an error when being selected. This occurs, e.g., for gmail accounts with the "[Gmail]" folder. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

* textinput: improve stemmingKoni Marti2023-05-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | Fix cursor index after stemming and reset it to the position where the completion should occur. Only stem to add more information and not remove any user input. Stemming is activated on the textinput line when the user presses the Tab key. The idea of stemming is to adjust the textinput line to the common ground (="the stem") of the completions options. When the stemmed input line is set, however, the cursor will be moved to the end of the line if there is a text part on the right side of the cursor where the completion should occur. Another Tab press will activate the onStem function again, which then removes the right part of the text input leading to the loss of the user input. This can be prevented by moving the cursor to the place of the completion after stemming. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

With this patch, the completion systems supports writing the templates by showing the available template data fields and template functions. Pressing <Tab> after }} will show the evaluated template in the completion menu. Complex template code, such as if-else statements work as well. Examples: :filter -f {{<Tab> will show the possible template data fields and functions :filter -f {{index (.To|email) 0}}<Tab> will show the value of the template expression in the completion list Pressing <Tab> twice after a completed template expression will substitute the expression with its value. :{{if match .Folder "INBOX"}}check-mail{{else}}cf INBOX{{end}} Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>
* commands: add OptionsProvider and OptionCompleterKoni Marti2023-05-168-38/+632
| | | | | | | | | | | | | | | | | | | Improve command completion by supporting option flags and option arguments completion. Option completion is activated when the command implements the OptionsProvider interface. Implementing the OptionCompleter allows the completion of individual option arguments. The completion interfaces harmonizes the completion behavior in aerc, makes the completion code clearer and simplifies the completion functionality. With this patch, the Complete method on commands will only have to deal with the actual completion, i.e. paths, folders, etc and not worry about options. To remove all options and its mandatory arguments from args, use commands.Operands(). Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

* dirtree: modify drawing of the dirtreeTim Culverhouse2023-05-162-19/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the dirtree drawing structure to be a bit more compact. The dirtree is drawn with one column left for a flag, which indicates if a parent is collapsed or expanded. Only draw the "flag" when the parent is collapsed. Change the flag to a '+' character to match common UI patterns of expanding lists having a '+' box. Don't draw the '>' character in the dirtree. This character is nice in the threaded message view, but clutters up the dirtree. I know this is a matter of preference, but this approach is similar to most other UI tree view and gives the dirtree an extra column of space. The original dirtree looks like this: ┌Inbox ├─>Sub └─>Sub And collapsed: -Inbox This patch changes it to: Inbox ├─Sub └─Sub And collapsed: +Inbox Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

* maildir: fix FSWatcher handling of eventsTim Culverhouse2023-05-111-40/+22
| | | | | | | | | | | | | | | | | | | | Commit ef4504e6baf5 ("maildir: fix handling of FSEvents") ambitiously tried to fix handling of file system events by handling different events in "proper" ways. Distributions and OSes report these FSEvents differently which creates a large amount of edge cases on what the right handling of each individual event should be. Revert part of ef4504e6baf5 which attempts to issue different messages based on the event. Add a debounce to file system events and always trigger a Refetch of the message list. This still fixes one of the "fixes" the referenced patch attempted at, where the UI was only told to refetch if the message count increased (but if messages disappeared externally, the maildir never updated).

* msgstore: fix handling of deleted messagesTim Culverhouse2023-05-111-5/+4
| | | | | | | | | | | | | | | | | | The msgstore trims the uid list when a message was deleted. It does so whether the message is in the message store or not. If the message was already deleted and a MessagesDeleted is received, the store will be trimmed regardless. This can cause spurious emails to be removed from the msgstore due to a race condition with the fs watcher / imap update channel. When a message is deleted, the UI will received two MessagesDeleted and in some cases trim the list, removing too many emails. Fix the handling of deleted messages so that the uid list is rebuilt of all messages except the deleted ones specifically.

* filters: fix option parsing on arm cpusRobin Jarry2023-05-113-37/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | When running colorize or wrap on ARM, both programs exit immediately displaying their help message whatever the provided arguments. This is caused by an implicit downcast of the getopt return value. On most architectures, char is signed by default. On ARM, char is unsigned for performance reasons. Since the signed int return value of getopt is forced into a char, the results differ on ARM compared to x86. * Add -Wconversion -Warith-conversion to CFLAGS in CI builds to ensure catching such issues in the future. * Fix all -Wconversion -Warith-conversion reported issues. * Wide char functions need to deal with wint_t and wchar_t and it is guaranteed that a wchar_t can always fit into a wint_t. Add explicit casts to silence the reported warnings.

* maildir: fix handling of FSEventsTim Culverhouse2023-04-282-8/+44
| | | | | | | | | | | | | | | | | | | Maildir uses a filesystem watcher to watch the currently selected directory for changes, updating the UI as necessary. Not all changes get updated based on the current logic. Send a MessageInfo if the event was a Rename. Send a MessagesDeleted if the event was a Remove. Tell the UI to refetch the list if the event was a Create. Note: This leads to some unnecessary fetching in the UI, as renames also come with a Create event in most cases. Koni suggested sending the MessageInfo and having the UI perform a binary search and inserting the message in the proper position. This is optimization is left out of this series, with a TODO left in the code.
