More mail flags can now be set, unset, and toggled, not just the
read/seen flag.
This functionality is implemented with a new `:flag` and `:unflag`
command, which are extensions to the matching `:read` and `:unread`
commands, adding support for different flags. In fact, the
`read`/`unread` commands are now recognized aliases to `flag`/`unflag`.
The new commands are also well documented in aerc(1).
The change mostly extends the previous read/unread setting functionality
by adding a selection for the flag to change.
This stops the ui being blocked while the resource is opened. The wait
ensures that resources are reclaimed when the process finishes while
aerc is still running.
The data was passed around as a string for some reason, which led to time
precision loss and wrong dates being displayed.
Simply pass the time as is to fix that.
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
Currently at least the notmuch and maildir worker only set messages as read
if a body part is fetched. The gpg abstraction however fetches the full message.
We can simply set the readstate when we create the messageview, avoiding the issue.
Once this is merged, we can cleanup both workers.
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.
Hi. This adds a template function to convert a time to the local time zone. And modifies
the default quoted_reply template to use it and show the time zone when formatting the
timestamp of the quoted message.
Previously, the quoted message timestamp was UTC and it would format it without the time
zone. And I thought it might be a little confusing or weird to some normal people when I
email them and I don't want normal people to be confused or think that I'm weird.
Apparently sending an event for every incoming messageInfo slows down
the application significantly.
Therefore this slows down the emmision rate, on the cost of being out of date
in some cases.
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
Actions such as read / unread or the addition of new messages do change
the read/unread/recent count. Hence we request an update from the workers.
Workers going over the network should probably cache the information and invalidate
it only if necessary
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.
If the message doesn't contain ':', we don't properly discard the
message, so we end up slicing it like msg[:-1].
This can be reproduced if one runs 'aerc foo', as the server receives
'foo' as the message.
'aerc foo' still doesn't do anything very user friendly, but at least it
doesn't panic horribly.
While at it, do the 'got message' log at the very beginning, so that the
user can see what message the server got before reporting the command as
invalid.

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
Before, pressing <Enter> when completions were visible would execute the
selected completion. As soon as completions were provided, the first
item would be selected. This could cause issues e.g. when changing
folders:
:cf <Enter>
Previously, this would have selected the first folder in the list. Now,
since <Tab>, <C-n>, etc have not been pressed to select the first
completion, the command above simply executes `:cf `.
To accomplish this, a "no-op completion" has been added at index -1.
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 popover is a special UI element which can be layered over the rest of
the UI (i.e. it is painted last) and can fall anywhere on the screen,
not just with the bounds of its parent's viewport/context. With these
special abilities comes the restriction that only one popover may be
visible on screen at once.
Popovers are requested from the UI context passed to Draw calls and
specify the anchor point and the desired dimensions. The popover is then
fit to the available space and placed relative to the anchor point.
A panic could happen when multiple delete messages are sent one after
another without waiting until there are no messages left to be deleted:

The make that blows up is:
uids := make([]uint32, len(store.uids)-len(msg.Uids))
This change simply checks whether the make is going to be valid before
starting to work on the actual delete. If there are more messages queued
to be deleted than what's left in the store, then we're obviously in an
inconsistent state, ask for an update and break.
This addresses occasional crashes when a `MessageInfo` event reached the message
store before `DirectoryContents`, particularly on slower (imap) accounts.
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.

Previously removing a tab would always pop from the history of tabs.
This checks to see if the closing tab is the one selected, if it is then
we use the history, otherwise we only need to change the selected tab if
it was after (to the right of) the closing tab, in which case we just
decrement the selected index.
When Reto Brunners patch is applied (which works really well for me), the user gets to see the message
returned by AercServer. Since this is nil if no errors were thrown it
prints "result: <nil>" to the cmd. This patch fixes that by just
returning success instead of the error message when err != nil.
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.
Add an onUpdateDirs handler. This is used to invalidate the dirlist and
redraw with the correct number of recent/unread/total messages is shown.
A config option and formatting options are provided.
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.
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.
Choose the readline defaults for the behavior of these two
functions/keybindings. Depending on the program, either of these can
delete the whole line.
Note that by default in [compose], <C-k> is bound to :prev-field<Enter>.
Leave it up to the user whether or not they want to rebind the key in
[compose].
Add a "new-message-bell" option to the UI section of aerc.conf. A new
hook into the message store allows the msglist widget to detect new
messages being added to the displayed list. When new messages are
delivered, and the new-message-bell option is enabled (as it is by
default), the terminal will beep.
When filter is active we want to use store.results instead of
store.uids, since we are dealing with a subset of the uids. Otherwise
any methods involving len will have undefined behavior.

Tabstrip didn't take into account the width of the context. Now, it just
shows as many tabs as can fit and truncates the last one if necessary.
In future it probably would be best to ensure that the selected tab is
rendered on the screen.
This adds tab completion to textinput components. They can be configured
with a completion function. This function is called when the user
presses <tab>. The first completion is initially shown to the user
inserted into the text. Repeated presses of <tab> or <backtab> cycle
through the completions list. The completions list is invalidated when
any other non-tab-like key is pressed.
Also changed is some logic for current completion generation so that
all available commands are returned when <tab> is pressed with no
current text and similarly for arguments of commands.
Aerc will keep track of the previous 1000 commands, which the user can
cycle through using the arrow keys while in the ex-line. Pressing up
will move backwards in history while pressing down will move forward.
This map represents a mapping from directory names to their associated
messagestores anyway so they should be under dirstore. This simply moves
them there and adds some methods required to interact with them.
This patch sets up the trigger config section of aerc.conf.
Each trigger has its own function which is called from the place where
it is triggered. Currently only the new-email trigger is implemented.
The triggers make use of format strings. For instance, in the new-email
trigger this allows the user to select the trigger command and also the
information extracted from the command and placed into their command.
To actually execute the trigger commands the keypresses are simulated.
Further triggers can be implemented in the future.
Formatting of the command is moved to a new package.
Executing :close on a terminal would panic due to it already having been
removed.
This is also related to the fact that removing a tab doesn't check for
whether it actually found a tab to remove or not.
The grid was not checking there was enough space for the cells so would
just attempt to create subcontexts that don't actually fit.
This attempts to use the remaining space and then if there is no space
then it just skips drawing this cell.
This command allows the user to change tab by giving the tab name. This
can be tab completed too. The previous tab is stored in the tabs module
so that when a new tab is created it is still possible to go to the
previous one.
Normal invocation is :ct folder
Previous tab is :ct -
If the column weights do not collectively divide the extent of the grid
layout then some width was not used and so would not be redrawn,
resulting in previous drawings showing through.
This fixes this by checking if there is any remainingExact width and if
there is it is assigned to the weighted columns by their proportion from
left to right.
This package can be used to provide a source for mapping mock UIDs back
to relevant keys for alternate backends. For example, for the Maildir
backend, we need to map between UID and message file names.
This introduces a new interface `Clickable`. I'd imagine this would be
implemented for most widgets eventually and would allow for programs run
in the terminal to also have their mouse events forwarded to them.
For the tabs it was relatively simple to check that the position of the
click is within the boxes for the tabs. For other components I'd imagine
that some state representing their currently drawn bounding box would be
useful.

Before, we were using several IMAP-specific concepts to represent
information being displayed in the UI. Factor these structures out of
the IMAP package to make it easier for other backends to provide the
required information.
A sequence-set is an IMAP-specific implementation detail. Throughout the
UI, aerc simply operates using lists of opaque identifiers. In order to
loosen the coupling between the UI and IMAP in particular, replace most
usages of imap.SeqSet with []uint32, leaving the translation to a SeqSet
to the IMAP backend as needed.
Before, the information needed to display different parts of the UI was
tightly coupled to the specific messages being sent back and forth to
the backend worker. Separating out a models package allows us to be more
specific about exactly what a backend is able to and required to
provide for the UI.
The current implementation has three classes of flags:
- readFlag
- delFlag
- flaggedFlag
The logic to check for them should be in parallel if branches rather
than in sequential if-else ladder.
Adds an archive command that moves the current message into the folder
specified in the account config entry.
Supports three layouts at this point:
- flat: puts all messages next to each other
- year: creates a folder per year
- month: same as above, plus folders per month
This also adds a "-p" argument to "cp" and "mv" that works like
"--parents" on mkdir(1). We use this to auto-create the directories
for the archive layout.
This makes it so an atomic `invalid` value is used instead of an unbuffered
channel. When many invalidations kick in, a lot of values were sent to the
channel.
(Since OnInvalidate's callback can be run in any goroutine, we need to be
careful about races here.)
This commit introduces a new Aerc.Tick function that should be called to
refresh the internal state. This in turn makes each AccountView process worker
events.
The UI goroutine repeatedly refreshes the internal state before drawing a new
frame. The reason for this is that many worker messages may need to be
processed for a single frame, and drawing the UI is far slower than refreshing
the internal state. This has been confirmed in my testing (calling Aerc.Tick
only once per frame results in a slower display).
Many synchronization code has been removed. We can now write widgets without
having to care so much about races. The remaining sync users are:
- widgets/spinner: the spinner value is updated from inside an internal
goroutine
- lib/ui/invalidatable: Invalidate may be called from any goroutine
- lib/ui/grid: same
- lib/ui/ui: an internal goroutine needs read access to UI.exit
- worker/types/worker: Worker.callbacks is used for both worker and UI
callbacks
The exact goroutine requirements for Drawable have been documented.
This was is more complicated than others. The cells list is accessed by
multiple goroutines:
- Some change the Grid's contents via AddChild/RemoveChild
- Some call Draw
- Some invalidate the grid via Invalidate
Invalidate calls are tricky to handle because they will also invalidate all
child cells. This will inturn trigger the cellInvalidated callback, which needs
to read the list of cells.
For this reason, we use a sync.RWLock which allows multiple concurrent reads.
Below is the race fixed by this commit.

MessageStore has a lot of exported fields that can be read from the outside.
Each read must be protected, because a call from Update could happen at any
time.
Many Drawable implementations have their own Invalidate and OnInvalidate
functions, with an unexported onInvalidate field. However OnInvalidate and
Invalidate are usually not called in the same goroutine. This results in a race
on this field, e.g.:

To fix this, introduce a new type, Invalidatable, which protects the field.
Unfortunately the Drawable must be passed to the callback function in
Invalidate, so we still need to re-implement this in each Invalidatable user.
