Having the origin at the top left instead of the bottom left is more
conventional and ergonomic. The only thing this complicates is
prompt-specific logic, where we care about the coordinates of the
bottom-most line on the screen.
For that reason, the bulk of the changes here are in vere, where we
treat the bottom-most line specially, drawing the spinner onto it.
Webterm is likewise updated to account for the new coordinate system.
Drum now opts to accept clicks anywhere on the screen, and does its best
to move the cursor as close to the clicked location as possible (within
the confines of the prompt).
%rez has always used "width & height". Certainly, "x & y" is more
standard than "row & column". As such, we settle on making %hop and %hit
respect the more natural ordering. This change is safe because these
interfaces haven't made it to livenet yet.
We update the sole protocol to more cleanly support multiple sessions.
Primarily, the "sole id" is updated to be a [@p @ta] instead of a @ta,
and it is now generated based off the connected dill session, rather
than statically.
This change ripples out to applications that support the sole protocol:
the subscription path becomes /sole/[ship]/[session] (as opposed to
/sole/[per-ship-constant]), and %sole-action pokes include the new id as
well.
For shoe agents, this means (at the very least) updating the function
signatures of the shoe arms.
/lib/sole has been updated to include helper functions for parsing a
sole-id from a subscription path, and turning a sole-id into its
corresponding path. It also has a function to aid in migrating old
sole-ids.
Existing sole agents are made to kick any known open sessions, forcing a
resubscribe by drum, so that they may use exclusively the new format
going forward. Third-party agents are recommended to do the same.
Note that some functionality, such as |link, still operates exclusively
on the default session. Improvements in this area to follow soon.
Resolves a good number of conflicts. Most notably, re-propagates removal
of gall's %onto, confirms new /app/herm behavior, coerces hood/drum
state adapters back into place, and updates webterm to use the latest
api.
No mark files exist for any of the drum marks, so trying to poke remote drums
would fail anyway, but relying on the mark system in that way seems a bit
fragile, so we add an explicit permission check.
Start with |start %desk %app-name
Everywhere in the kernel that we deal with marks, we infer the app it's
connected to and use the marks from that desk.
Also some light renaming in gall, especially path->wire and
current-agent->yoke.
Subsequent tasks:
- Dojo needs a syntax to run generators and threads from other desks
- The home desk should be split into at least a minimal base desk and
big "userspace" desk. Dill's initialization logic should be updated
to handle
- |show-package, |install, and |uninstall should to be written
- Clay should have smarter handling of system versions instead of just
ignoring what's on each desk. It's not clear that this will work
correctly when sys updates right now.
Implements tasks for creating and deleting new sessions, and allows
terminal handler agents to distinguish between sessions.
Includes bits of preparation in drum to more fully support multiple
distinct sessions, but doesn't get it all the way there just yet.
Gall would send %onto gifts to notify about app updates and update
failures. This would end up in dill, which printed some appropriate
text.
Here, we make gall responsible for doing this printing itself (by
having it explicitly ask dill to print some tape/tank), instead of
relying on the receiving end of some bespoke notification protocol.
The previous version allowed for redundant values (both [%bac ~] and
[%key ~ %bac ~] for example), had an odd constraint in @cF, and relied
unnecessarily on $<.
Also rewords some of the belt and blit descriptions.
Previously, we relied on foolish hacks, like [%met %bac], to send
"special" keystrokes with modifiers.
This updates the belt type to have %key, which represents a single
keystroke, with any combination of modifier keys.
Note that this has overlap with %txt to some extent. [%key ~ 'a'] should
be considered equivalent and preferred to [%txt 'a' ~], but updating
existing usage is left to a later commit.
%url blits are meant for "activating" urls. Of course, opening a new
browser tab from within a C program is difficult, so we don't do it.
This is still better than doing the faux activation by just printing
the url. term.c no longer really knows where/how to draw it, and it's
meant as interactive behavior rather than visual output, anyway.
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.
styx and stub are both defined in lull. Having functions for dealing
with them in zuse rather than userspace is fitting.
While not a _common_ format per se, it still seems best at home in
+format, instead of on its own.
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.
Only detects mouse clicks. Though, "9" mode seems broken, or unsupported
or something? Probably need to upgrade to "1000" mode or higher, but
that also reports scrolling events and such, which don't want to steal
from the context we're running in just yet.
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.
