This simplifies the behavior of individual blits, making their
implementation simpler and giving arvo more control.
This lets us write on top of existing content, instead of completely
replacing the affected row. Additionally, lets us draw starting at the
cursor position, instead of the leftmost column.
To retain the previous behavior, preface with [%hop 0] to move the
cursor to the start of the line, [%wyp ~] to clear the existing content,
and finally your %lin to render it.
Some of the remainder are still _presently_ unused, but point at
functionality we want to support again in the near future. The ones
removed here are either redundant or have no clear purpose.
As per the note a couple lines up, +fore depends on drum semantics being
active. We can only guarantee those being present for the default
session, not for any others. So, we print a warning when appropriate.
Before recent dill changes, this wouldn't always be visible, since it
would get drawn in place of (and subsequently get overwritten by) the
prompt. Now that it displays consistently again, it should look a bit
better than just a noun dump.
This is somewhat redundant with gall's own "reloading agent" printfs,
but you know what they say: printfs don't real!
This prepares us for actually making use of multiple session in a sane
way.
Notable implicit change is that we no longer crash on an "unrecognized
duct", instead always handling it as destined for the default session.
As follow-up to 3fdef1468, we now no longer store the prompt or cursor
in state. These were still used for view initialization, but it's more
appropriate to %hey the underlying console application in those cases.
The scry endpoints we remove, expecting clients that depended on them
to send a %hail instead.
No longer inserts newlines or redraws the prompt post-print, pushing
this responsibility down to drum where it belongs.
Additionally, separates the flow for dill's own output, from that of the
console application. This lets us keep the desired behavior for now, and
will ease reworking in the future.
Last-printed-line and cursor position are still kept around in dill
state, in order to respond to the relevant scry endpoints. These should
either be refactored to scry into the underlying console app, or be
removed entirely in favor of %hey.
Instead of confining you to just the bottom row. 0,0 is bottom left.
Doesn't behave exactly as expected for non-zero column coordinates yet,
but all in due time.
Likewise for belt. This necessitates renaming the %mor blit for newlines
to %nel, making this require a new runtime version. That's fine, more
breaking changes are to follow.
We can't molt until clay has gotten its pork or else we'll build the old
app against the new kernel. This ignores vegas, since we should get a
notification from clay on /sys/lyv.
When we changed wires from /a/foo to /ames/foo, our sorting function
started sorting by last character instead of first character, so breach
notifications were given to gall before ames. This made gall try to
resubscribe before ames cleared its state, so the message would be lost.
Fixes#4177
This had regressed during some breach-related merge. Multiple commits/branches
had touched this codepath recently, eating the code step change introduced in
#3217.
Fixes#4126.
* jb/motion:
pill: solid
zuse: remove %crud from vane-task
arvo: full vane names in $sign
aqua: build again (still broken)
arvo: reform of the scry reform
When you first boot, if you try talk to someone before your azimuth is
up-to-date (for example by import), then if they've ever breached
(twice) then you'll get breach notification, cancelling your message.
This changes is it so that if we haven't heard anything about this ship,
we don't signal a breach.
The implementation complexity is primarily because we need
eth-watcher/azimuth-tracker to produce an update of a list instead of a
list of updates. This way, Jael can keep a "state as of the beginning
of this move" variable to check when deciding whether to signal a
breach.
