* threading: implement on-the-fly message threadingKoni Marti2022-02-2410-4/+440
| | | | | | | | | | | | | | | | | | | | implement message threading on the message store level using the jwz algorithm. Build threads on-the-fly when new message headers arrive. Use the references header to create the threads and the in-reply-to header as a fall-back option in case no references header is present. Does not run when the worker provides its own threading (e.g. imap server threads). Include only those message headers that have been fetched and are stored in the message store.

* commands: add expand-folder and collapse-folderKoni Marti2022-02-233-0/+48

* dirtree: implement foldable tree for directory listKoni Marti2022-02-236-3/+517
| | | | | | | | | | | | | | implement a foldable tree for the directory list. Expand all parent directories when a hidden directory is selected with the change-folder command. folders-sort considers the top-level directories only. The folders and foldersexclude filters work with the full directory path. Enable tree view by adding 'dirlist-tree=true' to the config file.

* filters: port colorize to awkRobin Jarry2022-02-211-168/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python is not available on all systems. Port the colorize filter to awk as it is a more widespread POSIX utility. Users are free to copy the filter into their home dir and tweak the colors to their needs. The highlighted items are: =============== ======= ======= ========= ================= Item Red Green Blue Color =============== ======= ======= ========= ================= quoted text 1 95 175 255 Blue quoted text 2 255 135 0 Orange quoted text 3 175 135 255 Purple quoted text 4 255 95 215 Pink quoted text * 128 128 128 Grey diff meta 255 255 255 White bold diff chunk 205 0 205 Cyan diff added 0 205 0 Red diff removed 205 0 0 Green signature 175 135 255 Purple header 175 135 255 Purple url 255 255 175 Yellow =============== ======= ======= ========= ================= This assumes a terminal emulator with true color support and with a dark/black background.

* config: fix default text/plain filter0.8.0Robin Jarry2022-02-191-1/+1
| | | | | | | | | | | | | | | | | | ; is a special character for the INI format. It starts a comment and apparently cannot be escaped nor quoted. This causes the default text/plain filter to be truncated and causes this obscure error when viewing a message: sh: 1: Syntax error: Unterminated quoted string Debugging shows that the filter command is: sh -c "sed 's/^>\\+.*/\\x1b[2" Remove the explicit dim style. It should be the default anyway. Fixes: 7c3ce816c8a6 ("config: set a default filter for text/plain") Signed-off-by: Robin Jarry <robin@jarry.cc>

* config: do not hardcode sharedirRobin Jarry2022-02-197-51/+102
| | | | | | | | | | | | Instead of using a static SHAREDIR at compile time, use a list of standard paths to use at runtime for templates, config files and stylesets.

* imap: improve reconnect stabilityKoni Marti2022-02-062-8/+22
| | | | | | | | | | | | | | | | improves the robustness of the imap reconnect feature which was introduced in commit beae17a6da37 ("imap: auto-reconnects on connection error"). If a connection error is emitted, the message list is cleared and a corresponding error message is shown in the ui. Status bar is updated as well. Upon reconnect, the directories and the message list will be re-fetched (same behavior as the connect command). Reconnect can be enabled and disabled with the connect and the disconnect commands.

* imap: do not abort on malformed messagesRobin Jarry2022-02-061-1/+7
| | | | | | | | | | | | | | Some messages contain invalid headers, textproto.ReadHeader fails with an error: malformed MIME header key: From nobody Fri Jan 14 19 And all other messages of the selected folder are ignored.

* maildir: defer the count of recent messagesRobin Jarry2022-01-301-25/+32
| | | | | | | | | | | | | | | Since commit 01c96e78dfe8 ("Update DirectoryInfo handling for maildir"), flags are checked for every message of a folder when entering it. Iterating over all messages of a folder takes a long time for large collections of emails. Only count the number of messages and state that the directory info counts are not accurate.

* recover: recover emails from tempdir after a crashKoni Marti2022-01-291-0/+110
| | | | | | | | | | | | | | | | | | | implements a recover command that searches the local temp dir for aerc emails. If a file is found and selected, a new composer tab will open with the file contents as the message body. No header data is stored in the temp file and thus this information cannot be recovered. Recover will not remove the temporary file unless the force flag (-f) is explicitly used. This recovery method only works when the editor buffer is saved to disk and the Close() function of the composer has not been called yet. Sending, postponing or quitting will call the Close() function which removes the temporary file completely. After Close() is called, no recovery is possible anymore.

* aerc: shutdown if socket communication failsAdnan Maolood2022-01-241-10/+13
| | | | | | | | | When provided with a mailto argument, aerc tries to connect to an existing instance via a unix socket. If that fails, it starts up a new instance and tries again. However, if that fails again (e.g. if the unix server could not be started) then the new instance will remain open without any indication that an error occured. Instead, shutdown the new instance so the user can see the error message.

* dirlist: skip unnecessary change-folder actionKoni Marti2022-01-241-39/+55
| | | | | | | | | | when traversing the directory list, aerc will fetch the contents for every directory even though the user might just move on to the next.
