* statusline: refactor to make it more customizableKoni Marti2022-04-251-1/+4
| | | | | | | | | | | | | | | | | Refactor statusline by clearly separating the rendering part from the text display. Use printf-like format string for statusline customization. Document printf-like format string to customize the statusline. Allow to completely mute the statusline (except for push notifications) with a format specifier. Provide a display mode with unicode icons for the status elements.

* Initialization fix for dynamic foldersAivars Vaivods2022-04-141-0/+9
| | | | | | | | | | | | | | | | | | | There is an issue with backends, that provide dynamic folders, namely when opening folder, that isn't defined in config file, you get empty folder. To actually get messages listed, you need to open that folder twice. At first attempt only DirectoryInfo is fetched and new MessageStore created. Second attempt populates previously created MessageStore with list of messages. For pre-configured folders, DirectoryInfos are fetched upon connection to backend and, when folder is opened, MessageStore is updated with list of messages.

* sort: keep sort criteria applied to folderKoni Marti2022-03-251-2/+2
| | | | | | | | | | | | | | | Keep the sort criteria applied to the selected folder until the default sort order should be restored. Call the sort command without arguments to restore the default sort order. The current behavior is that the default sort order is restored as soon as the folder reloads. This happens often and then the results of the sort command are lost. This makes the sort command not very user-friendly. Instead, we should keep the sort criteria applied until the user explicitly wants to restore the default sort order again.

* logging: added a log on panicMoritz Poldrack2022-03-236-1/+27
| | | | | | | | | | | | | Since panics still regularly "destroy" the terminal, it is hard to get a stack trace for panics you do not anticipate.

* compose: make headerEditor focusing more reliableTim Culverhouse2022-03-222-21/+9
| | | | | | | | | | | | Focusing header editors was hardcoded as integers which only worked with the default ui. If a user changed the UI to, for example, put CC as a field below "to", FocusSubject would focus the CC field instead of the subject. This commit reuses and modifies the function FocusEditor to generalize the focusing of header editors - which can now be called by name via FocusEditor(name string) Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
* msglist: update message counter upon filter changeKoni Marti2022-03-201-0/+6
| | | | | | | | | | | | | | | | Update message counter in msglist when the filter is changed (either set or cleared in the msgstore). When we apply a filter, we change the number of uids in the message store. This can unintentionally trigger the storeUpdate() function of the msglist which checks the number of uids for new messages and advances the pointer by the difference in the number of messages. This can be avoided when we update the message counter upon changing the filter.

* viewer: add key passthrough modekt programs2022-03-142-1/+19
| | | | | | | | | | | | | | | | When trying to search in less, keys bound to viewer functions can't be used as part of the search query, which makes the search useless. Add a view::passthrough binding mode and a :toggle-key-passthrough command go toggle in and out of that mode. By default, typing '/' in the viewer is bound to enabling key passthrough and automatically inserting '/', to easily enter "less" search mode. When in the passthrough mode, all bindings are ignored by default. The default binds.conf only defines a single keybinding in that mode: <Esc> to get back out. $ex is bound to <C-x> to allow typing colons.

* aerc: always check SelectedAccount return valueRobin Jarry2022-02-253-22/+32
| | | | | | | | | | | | | | | | aerc.SelectedAccount() is used in lots of places. Most of them without checking the return value. In some cases, the currently selected tab is not related to any account (widget.Terminal for example). This can lead to unexpected crashes when accessing account specific configuration. When possible, return an error when no account is currently selected. If no error can be returned, fallback to non-account specific configuration.

* 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.

* dirlist: improve change-folder responsivenessKoni Marti2022-01-241-2/+2
| | | | | | | | | | | improves change-folder responsiveness. When changing folders, the highlighted directory is currently updated in a callback function to the open-directory action. This creates an unpleasent lag in the ui until the entire operation is done.

* terminal: fix nil pointer dereference in pty.GetsizeKoni Marti2022-01-191-1/+4
| | | | | | | | | | | | | pty.Getsize() is used in the Draw function of the terminal widget and wraps the pty.GetsizeFull() function. However, pty.Getsize does not check the returned error from pty.GetsizeFull before dereferencing the winsize struct. In case of an error, this will cause a nil pointer deference and panic. This has been reported in the upstream package, but in the meantime, we can directly use pty.GetsizeFull.

* pgp: PGP/MIME encryption for outgoing emailsKoni Marti2022-01-071-9/+75
| | | | | | | | | | | | | | | | | | | | | implements PGP/MIME encryption with go-pgpmail. The Encrypt() function of go-pgpmail requires a list of public keys which are taken from the keystore. The keystore is searched for the email addresses of all recipients (to, cc, and bcc). If you want to be able to read the encrypted email afterwards, add yourself as a recipient in either to, cc, or bcc as well. Public keys can be exported from gpg into aerc as follows: $ gpg --export >> ~/.local/share/aerc/keyring.asc When composing a message, the encryption is enabled with the ":encrypt" command. This sets a bool flag in the Composer struct. A reapted application of this command will toggle the flag. The encrypted message can also be signed by using the ":sign" command before or after ":encrypt". References: https://todo.sr.ht/~rjarry/aerc/6 Signed-off-by: Koni Marti <koni.marti@gmail.com>

| | | | | | | | | | | | | | | | | implements PGP/MIME signing with go-pgpmail. The Sign() function of go-pgpmail requires a private (signing) key. The signing key which matches the senders email address (from field in email header) is looked up in aerc's copy of the keyring. Private keys can be exported from gpg into aerc as follows: $ gpg --export-secret-keys >> ~/.local/share/aerc/keyring.asc A message is signed with the ":sign" command. The sign command sets a bool flag in the Composer struct. Using the command repeatedly will toggle the flag.

* binds: add account specific bindingsJonathan Bartlett2021-12-111-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using aerc for multiple accounts often bindings might differ slightly between accounts. For example: * Account A archives to one directory (:archive) * Account B archives to monthly directories (:archive month) Add account specific bindings to allow the user to add a "context" to a binding group using a context specifier and a regular expression. Currently the only context specifier is 'account'. The regular expression is validated against the accounts loaded from accounts.conf and the configuration fails to load if there are no matches. Contextual bindings are merged with global bindings, with contextual bindings taking precedence, when that context is active. Bindings are be configured using a generic pattern of 'view:context=regexp'. E.g.: # Globally Applicable Archiving [messages] A = :read<Enter>:archive<Enter> # Monthly Archiving for 'Mailbox' Account [messages:account=Mailbox$] A = :read<Enter>:archive month<Enter> In the above example all accounts matching the regular expression will archive in the monthly format - all others will use the global binding.

* notmuch: allow sort by file orderKalyan Sriram2021-11-131-1/+7
| | | | | | | | | | | | When using the notmuch backend, it often makes more sense to sort folders (actual virtual folders, or queries) by the order specified in the query-map file, rather than alphabetically. This patch introduces a configuration option (disabled by default) that allows this. Additionally, due to the notmuch backend previously using maps (which are order-undefined) to store the list of queries, default query selection on aerc startup fluctuated. This patch fixes that by using slices to store query order.
