* 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.

* imap: auto-reconnects on connection errorKoni Marti2022-01-191-1/+2
| | | | | | | | | if the worker emits a connection error, the ui will automatically send back a reconnect command. The worker then establishes a new connection. Auto-reconnect is disabled when the user sends the disconnect command. Fixes: https://todo.sr.ht/~rjarry/aerc/1 Signed-off-by: Koni Marti <koni.marti@gmail.com>
* imap: emits connection error on logoutKoni Marti2022-01-191-0/+3
| | | | | | | | implements a new connection error message. This allows the worker to emit a connection-related error message to the ui when the imap client closes the loggedOut channel. Signed-off-by: Koni Marti <koni.marti@gmail.com>
* fix segfault when copy-pasting into compose editorKoni Marti2022-01-141-0/+3
| | | | | | | | | fixes the segmentation fault when copy-pasting a large text into the composer editor. The problem is a concurrent read of the vterm field in the Terminal widget in its flushTerminal() method which can be avoided with a mutex.

| | | | | | | as per the discussion https://lists.sr.ht/~sircmpwn/aerc/patches/15367 this handles completions in `completer/completer.go` by enabling the completer to return a `prefix` that will be prepended to the selected completion candidate.
* 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>
* pgp: PGP/MIME signing for outgoing emailsKoni Marti2022-01-071-17/+96
| | | | | | | | | | | | | | | | | 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.

* style: customize vertical and horizontal border charactersDian M Fay2021-11-302-3/+5
| | | | | | | | | New border-char-horizontal and border-char-vertical config settings in aerc.conf allow users to modify border appearance from the default 1-wide/tall blank space. In stylesets, border.fg now affects the foreground color when custom characters are defined. Signed-off-by: Robin Jarry <robin@jarry.cc>
* 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.
* messages: allow displaying email threadsy0ast2021-11-132-81/+182
| | | | | | | | | | | | | Display threads in the message list. For now, only supported by the notmuch backend and on IMAP when the server supports the THREAD extension.

| | | | | | | | | | When composing a message, there is an empty fill line between the headers and the text editor.

* widgets/terminal: Only call vterm.ScreenCell.Attrs once in styleFromCellClayton Craft2021-04-131-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a substantial performance issue when scrolling emails with long/complicated contents, where scrolling down a single line can take something like hundreds of ms before the screen is updated to reflect the scroll. It's really bad if the email has lots of columns, e.g. like if it's an html email that was passed through a filter (w3m, etc) to render it. Using pprof, I found that the multiple calls to vterm.ScreenCell.Attrs() in styleFromCell were really really expensive. This patch replaces them with a single call. Here's a before and after with a simple, but very manual test of opening a large email with contents that went through a w3m filter and continuously scrolling up and down over and over for ~30 seconds: *** Before: ----------------------------------------------------------+------------- flat flat% sum% cum cum% calls calls% + context ----------------------------------------------------------+------------- 28.25s 100% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.PartSwitcher.Draw 0 0% 99.94% 28.25s 82.31% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.PartViewer.Draw 28.25s 100% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.Terminal.Draw ----------------------------------------------------------+------------- 28.25s 100% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.PartViewer.Draw 0 0% 99.94% 28.25s 82.31% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.Terminal.Draw 19.23s 68.07% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.Terminal.styleFromCell 6.04s 21.38% | github.x2ecom..z2fddevault..z2fgo..z2dlibvterm.Screen.GetCellAt 1.38s 4.88% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2flib..z2fui.Context.Printf 0.62s 2.19% | runtime.mapassign 0.43s 1.52% | runtime.mapaccess2 0.20s 0.71% | runtime.newobject 0.19s 0.67% | runtime.callers (inline) 0.07s 0.25% | runtime.makeslice 0.07s 0.25% | runtime.mallocgc ----------------------------------------------------------+------------- 19.23s 100% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.Terminal.Draw 0 0% 99.94% 19.23s 56.03% | git.x2esr.x2eht..z2f..z7esircmpwn..z2faerc..z2fwidgets.Terminal.styleFromCell 19.21s 99.90% | github.x2ecom..z2fddevault..z2fgo..z2dlibvterm.ScreenCell.Attrs *** After: ----------------------------------------------------------+------------- flat flat% sum% cum cum% calls calls% + context ----------------------------------------------------------+------------- 0.31s 100% | git.x2esr.x2eht/~sircmpwn/aerc/widgets.Terminal.Draw 0 0% 99.87% 0.31s 1.33% | github.x2ecom/ddevault/go-libvterm.NewPos 0.25s 80.65% | runtime.callers (inline) 0.04s 12.90% | runtime.gomcache (inline) ----------------------------------------------------------+------------- 8.40s 100% | github.x2ecom/ddevault/go-libvterm.Screen.GetCellAt 0 0% 99.87% 8.40s 36.11% | github.x2ecom/ddevault/go-libvterm.Screen.GetCell 7.14s 85.00% | github.x2ecom/ddevault/go-libvterm._cgoCheckPointer 0.54s 6.43% | runtime.callers (inline) 0.35s 4.17% | runtime.exitsyscall 0.11s 1.31% | runtime.deferprocStack 0.07s 0.83% | doentersyscall 0.07s 0.83% | runtime.getg 0.05s 0.6% | runtime.casgstatus 0.03s 0.36% | _init 0.03s 0.36% | runtime.gomcache (inline) ----------------------------------------------------------+------------- 8.46s 100% | git.x2esr.x2eht/~sircmpwn/aerc/widgets.Terminal.Draw 0 0% 99.87% 8.46s 36.37% | github.x2ecom/ddevault/go-libvterm.Screen.GetCellAt 8.40s 99.29% | github.x2ecom/ddevault/go-libvterm.Screen.GetCell 0.06s 0.71% | runtime.callers (inline) ----------------------------------------------------------+------------- 0.31s 100% | git.x2esr.x2eht/~sircmpwn/aerc/widgets.Terminal.styleFromCell 0 0% 99.87% 0.31s 1.33% | github.x2ecom/ddevault/go-libvterm.ScreenCell.Attrs )

* compose: use a proper header instead of a string mapReto Brunner2020-11-142-135/+189
| | | | | | | | | | | | | Prior to this commit, the composer was based on a map[string]string. While this approach was very versatile, it lead to a constant encoding / decoding of addresses and other headers. This commit switches to a different model, where the composer is based on a header. Commands which want to interact with it can simply set some defaults they would like to have. Users can overwrite them however they like. In order to get access to the functions generating / getting the msgid go-message was upgraded.

* Apply relevant msglist styles in orderChris Vittal2020-11-011-13/+14
| | | | | | | | | | | | | | | | | | Allow styles to be layered over a base style. The list of styles to apply is layered over the base style in order, such that if the layer does not differ from the base it is not used. The order that these styles are applied in is, from first to last: msglist_default msglist_unread msglist_read (exclusive with unread, so technically the same level) msglist_flagged msglist_deleted msglist_marked So, msglist_marked style dominates. This fixes an issue where the msglist_deleted style was not being applied.

* base models.Address on the mail.Address typeReto Brunner2020-08-201-7/+8
| | | | | | | | | | | | This allows us to hook into the std libs implementation of parsing related stuff. For this, we need to get rid of the distinction between a mailbox and a host to just a single "address" field. However this is already the common case. All but one users immediately concatenated the mbox/domain to a single address. So this in effects makes it simpler for most cases and we simply do the transformation in the special case.
* Add support for :rmdirARaspiK2020-08-191-0/+2
| | | | | | | | | | | | | | | | | | | | | The `:rmdir` command removes the current directory (`-f` is required if the directory is not empty). This is not supported on the notmuch backend. An issue with the maildir backend is that some sync programs (e.g. offlineimap) may recover the directory after it is deleted. They need to specifically be configured to accept deletions, or special commands need to be executed (e.g. `offlineimap --delete-folder`) to properly delete folders. A danger of using this on the IMAP backend is that it is possible for a new message to be added to the directory and for aerc to not show it immediately (due to a slow connection) - using `:rmdir` at this moment (with `-f` if the directory already contains messages) would delete the directory and the new message that just arrived (and all other contents). This is documented in aerc(1) so that users are aware of possible risks.
* show error if account view creation failsReto Brunner2020-08-103-8/+39
| | | | | | | | This can happen for example if aerc is compiled without notmuch support but the notmuch worker is requested. Pushing a status message isn't good enough, as this gets overridden pretty quickly if one has multiple accounts configured. So we show a fullscreen error instead.
