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:

Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.
Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.
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.
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.
There is a window where a new dir entry isn't yet in the dirlist.dir.
dirlist.ensureScroll however expected to always find a valid index.
Add a check so that we don't try to scroll to a -1 index.
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.
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.
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.
Introduce the ability to configure stylesets, allowing customization of

some people send around huge html without any newline in between.
This did overflow the default 64KB buffer of bufio.Scanner.
If something can't fit in a GB there's no hope left
Also, ignoring errors is bad mkey
Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
Added a 'folders-exclude' option that allows removing selected folders
from the directory list sidebar. My motivating example was that removing
a single folder from the list using Golang regexes seemed pretty hard,
so this is a better way to do it. The excluded folders list is included
in the man page.
This changes the scrolling to be done on the draw, when the height is
updated, ensuring that the selected item is kept on screen during
resizing.
Also, this ensures that messages will fill the screen when resizing the
window, for instance, shrinking and then growing drags down more
messages if possible.
This is a transplant of the dirlist scrolling logic.
The grid used static sizes which meant that changing settings didn't
have an effect on elements of the ui, notably the sidebar width. This
patch makes the `Size` parameter of a cell a function which returns the
`int`, allowing for dynamic sizes.
A `Const` function is also included for ease of use for static sizes.
The following functionalities are added to configure aerc ui styles.
- Read stylesets from file with very basic fnmatch wildcard matching
- Add default styleset
- Support different stylesets as part of UiConfig allowing contextual
styles.
- Move widgets/ui elements to use the stylesets.
- Add configuration manual for the styleset
Especially if one tries to interact with all marked messages there could be
the case that not all headers are fetched yet, hence the messageInfo is still nil.
This segfaults a lot of commands which in principle only need the uid to complete.
If we switch to uids, this issue can be alleviated for those commands.

This command uses the Postpone folder from the account config to save
messages to. Messages are saved as though they were sent so have a valid
'to' recipient address and should be able to be read back in for later
editing.
Due to headers being essentially free text, we constantly run into issues
with parts of the body being interpreted as headers.
Remove the ability to overwrite headers to avoid that, while keeping the ability
to specify headers in the template files.
Fixes#383
This adds the commands pin-tab and unpin-tab. Once pinned a tab lives on
the left of the tabstrip and has a configurable marker, defaulting to `
before its name.
This changes the ui to show the spinner while we are sorting. It only
shows one line of the spinner since there are an unknown number of
messages at this time.
Updates to a store can be asynchronous so we shouldn't select it just
because it had an update. Selection of the stores should be driven by
explicit user commands.
This fixes an issue with the updated count logic, where only fetched messages
where counted to the exists string of the rue count.
Note that the count is still broken (we only count read / unread messages we
fetched, but that is the same behaviour as prior to the commit
66b68f35b3)
This reverts commit bd4df53009.
I did not properly untangle the opening / dirlist update of each other.
This interferes with the imap worker, hence the revert
Currently the dirlist ignores the counts provided by the dirInfo.
However some of the workers can actually provide accurate counts much quicker
than if we count the flags.
Eventually we will also want to enable displaying counts for background folders,
where the brute force counting won't work as none of the headers are fetched yet.
This commit models it in an opt-in manner, if the flag isn't set then we still
count the messages manually.
Previously, sending a DirectoryInfo assumed that a directory change
happened. However we don't want that if we only want to update the
unread message count.

So let's do that.
The go compiler can't help much with untyped int constants.
Even though the only valid constants are 0-3 it will happily accept 4 as input.
Let's let the go compiler worry about correctness here. This also allows people
not very familiar with the code to use it properly via auto completion.

Previously the workers returned a mixture of decoded / encoded parts.
This lead to a whole bunch of issues.
This commit changes the msgviewer and the commands to assume parts to already
be decoded
In order to accommodate for that, the headerlayout needed to be rewritten
to pass the filter criteria back to the msgviewer, instead of just using
the normal headers.
Note that, until we get color configuration, this means that the user *must*
have the %Z verb in the index format else it'll be horribly confusing
as no visual indication is provided
Rather than showing completions inline in the text input, show them in a
popover which can be scrolled by repeatedly pressing the tab key. The
selected completion can be executed by pressing enter.
A new config options for accounts.conf (folders-sort) was added to
allow a user to choose which folders should be shown on top.
My use case was to avoid stepping into heavy, but rarely viewed folders
when cycling through other often accessed ones.
To test add this to your account.conf:
folders-sort = INBOX,Sent,Archive
INBOX, Sent and Archive should then show at the top of your dirlist,
and all other folders should come next in alphabetical order.
Very important fix. Remove garbage from reply message headers. Till
now all Original fields were send in reply, which we do not want and could
lead to uncorrect email message.
Hi!
This patch will fix missing filename if it is RFC2231 encoded with charset

Yes, this should be forbidden :-). Anyway, best solotion in such cases

This patch parses the processed template for headers and populates
matching header editors.
Those are then stripped from the template body before prepending the template
and remaining header fields to the composer content.
The main motivation for this is keeping receiver, sender and subject
lines in the template file and generating the message subject from the

Adds a message indicating the user's ability to :save or :pipe a message
with an unsupported mimetype and also adds a selector widget (similar to
the tutorial).
The selector widget was previously defined in the account wizard module,
so this commit breaks it out into its own module to allow for re-use.
Further, modify the BeginExLine() function to take an argument that
pre-populates the command line, allowing functions to initiate an ex
command without executing it.

There is a command and config option. The criteria are a list of the
sort criterion and each can be individually reversed.
This only includes support for sorting in the maildir backend currently.
The other backends are not supported in this patch.
This adds the ability for per-account signatures in the accounts.conf
config file. The signature is added to emails in the editor at the
bottom of the email. This includes when forwarding, replying to, and
composing emails.
There are two config options: signature-file and signature-cmd. The
former allows a signature to be read from a file and the latter allows
an arbitrary command to be executed to return the signature.
The config options have been documented in aerc-config
Add an onUpdateDirs handler. This is used to invalidate the dirlist and

This adds the Mouseable interface. When this is implemented for a
component that item can accept and process mouseevents.
At the top level when a mouse event is received it is passed to the
grid's handler and then it trickles down until it reaches a component
that can actually handle it, such as the tablist, dirlist or msglist.
A mouse event is passed so that components can handle other things such
as scrolling with the mousewheel. The components themselves then perform
the necessary actions.
Clicking emails in the messagelist opens them in a new tab.
Textinputs can be clicked to position the cursor inside them.
Mouseevents are not forwarded to the terminal at the moment.
Elements which do not handle mouse events are not required to implement
the Mouseable interface.
Allows to set `ui.spinner=` to a string which is then split by
`ui.spinner-delimiter=` (Default: comma) instead of having a hard coded
animation.

it trims whitespaces breaking the default animation.

Sometimes I observe out-of-order messages when using a maildir inbox. It
appears that the UIDs for these messages are returned out of order by
the MessageStore. In order for a maildir MessageStore to return messages
in most recently received order, it must have already opened all
messages and parsed the date to use as a sort key. Rather than implement
that, simply sort messages by time as we display. This fix shows my
emails in order.
Usage:
:prompt <prompt> <command...>

appends that input as the last argument to the command and executes it.
The input is passed as one argument to the command, unless it is empty,
in which case no extra argument is added.
