Reorder products of some functions in the edit/ and sandbox/ apps. My
recent realization: always return 'real' products before ones that just
indicate an ingredient is mutable.

Update sandbox/ with recent changes to edit/ (commit 3695 onwards).
[Incidentally, this is the first commit to be made while running on
OpenBSD. Simulated and host systems are going to blur together from now
on.]

Cleaning up the console interfaces before we start changing the socket
interfaces to look like them. Reading from sockets need to be
non-blocking just like reading from the console.

Stop requiring jump instructions to explicitly provide a ':label' type
for jump targets.
This has been a source of repeated confusion for my students:
a) They'd add the ':label' to the label definition rather than the
jump target (label use)
b) They'd spend time thinking about whether the initial '+' prefix was
part of the label name.
In the process I cleaned up a couple of things:
- the space of names is more cleanly partitioned into labels and
non-labels (clarifying that '_' and '-' are non-label prefixes)
- you can't use label names as regular variables anymore
- you can infer the type of a label just from its name

Revert commit 3457, where I switched the unicode characters used in the
edit/ app to something that doesn't render double-wide in html. It turns
out that the new unicode characters made iTerm2 sluggish in alt-tabbing
between windows. (Commit 3488 only fixed the screen-clearing issue.)
I haven't reverted the html files. I'm going to redo commit 3457 next so
the html files continue to render like they do now.

Switch around some unicode characters in the edit/ app so that it
renders more cleanly in html (with monospace fonts).

Ugly that we didn't need 'screen' to provide a type in scenarios
(because assume-screen expands to a definition of 'screen') but we did
need a type for 'console'. Just never require types for special names in
scenarios.

A long-standing problem has been that I couldn't spread code across
'run' blocks because they were separate scopes, so I've ended up making
them effectively comments. Running code inside a 'run' block is
identical in every way to simply running the code directly. The 'run'
block is merely a visual aid to separate setup from the component under
test.
In the process I've also standardized all Mu scenarios to always run in
a local scope, and only use (raw) numeric addresses for values they want
to check later.

Well, almost. I can't use them in some places in C++ where I'm just
creating a temporary reagent without passing it through transforms. Like
in some unit tests. I can't use them in memory-should-contain.
And there's one remaining bug: I can't use abbreviations in a couple of
places in 075channel.mu.

Process type abbreviations in function headers.
Still a couple of places where doing this causes strange errors. We'll
track those down next.
|
| |
|
|
|
| |
In the process I've uncover a couple of situations we don't support type
abbreviations yet. They're next.

In some rare situations the editor would join a line with the next when
it should simply wrap to the next screen row. Thanks Caleb and Ella
Couch for finally running into a situation that was easy to reproduce.
The scenario diffs are misleading on this commit. I had to:
a) delete the obsolete 'editor-wraps-cursor-after-inserting-characters'
because it was written back when a line just large enough to fit in a
single line would not wrap:
| | <-- screen boundary
abcde
These days it will wrap after making room for the wrap indicator:
| | <-- screen boundary
abcd↩
e
b) rename editor-wraps-cursor-after-inserting-characters-2 to
editor-wraps-cursor-after-inserting-characters-in-middle-of-line
c) create a new scenario demonstrating the bug:
editor-wraps-cursor-after-inserting-characters-at-end-of-line

Clean up this helper before we start redoing sandbox menubars.
|
| |
|
|
|
|

In the process I've also simplified the sandbox/ app. Since it's
impossible for sandbox editors to span multiple pages, we can drop all
scroll support altogether.

Now that we no longer have non-shared addresses, we can just always
track refcounts for all addresses.
Phew!

I'm dropping all mention of 'recipe' terminology from the Readme. That
way I hope to avoid further bike-shedding discussions while I very
slowly decide on the right terminology with my students.
I could be smarter in my error messages and use 'recipe' when code uses
it and 'function' otherwise. But what about other words like ingredient?
It would all add complexity that I'm not yet sure is worthwhile. But I
do want separate experiences for veteran programmers reading about Mu on
github and for people learning programming using Mu.

This is the one major refinement on the C programming model I'm planning
to introduce in mu. Instead of Rust's menagerie of pointer types and
static checking, I want to introduce just one new type, and use it to
perform ref-counting at runtime.
So far all we're doing is updating new's interface. The actual
ref-counting implementation is next.
One implication: I might sometimes need duplicate implementations for a
recipe with allocated vs vanilla addresses of the same type. So far it
seems I can get away with just always passing in allocated addresses;
the situations when you want to pass an unallocated address to a recipe
should be few and far between.

Thanks Jack and Caleb Couch for the idea.
