When the list of completions from the external command doesn't have
associated contact names, the email address we attempt to parse was
being terminated with a newline. Now, we strip the trailing newline if
present.
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.
When addresses contain special characters, net/mail MIME-encodes them
to a valid RFC 5322 address for use in headers. However, these are not
pleasant for human consumption, so we decode them for use in the
completion list. Aerc properly encodes addresses when the message is
sent.
This patch also removes surrounding white space from contact names, if
present.
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 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.
This fixes an upstream issue where improperly named maildir files could
cause a panic. Now, we simply show an error and don't display the
message if the backing file is not named according to the maildir spec.
