Swap printing generalized objects using arc's infrastructure to be the
$-prefixed debug helper, while the erstwhile $print-key-to-host becomes
the primitive print-character to host.
|
|
|
|
|
| |
Also clean up various prints from last few commits.
As a convention, for debugging we always print directly to host.

This will let me swap in a fake in tests.
Still hacky, though. I'm sure I'm not managing the parameter right in
the chessboard app.
And then there's the question of whether it should also appear as an
output operand.
But it's a start. And using nil to mean 'real' is a reasonable
convention.
If I ever need to handle multiple screens perhaps we'll have to switch
to 1:literal/terminal and 2:literal/terminal, etc. But those are equally
easy to guard on.

'default-scope' is now 'default-space'
'closure-generator' is now 'next-space-generator'
The connection to high-level syntax for closures is now tenuous, so
we'll call the 'outer scope' the 'next space'.
So, let's try to create a few sentences with all these related ideas:
Names map to addresses offset from a default-space when it's provided.
Spaces can be strung together. The zeroth variable points to the next
space, the one that is accessed when a variable has /space:1.
To map a name to an address in the next space, you need to know what
function generated that space. A corollary is that the space passed in
to a function should always be generated by a single function.
Spaces can be used to construct lexical scopes and objects.

We expect users to come across mu from arbitrary bits of code, so try to
make each line as self-contained as possible.

This pollutes our traces with all 'system software'. Too much trouble to
keep it out; just lump it for now. Who knows, might even be useful. Most
of the time convert* labels are easy to grep out when debugging.

Will the 'lightweight tools' really be all that useable if we encourage
people to layer them one atop another and track precisely what inputs
each can accept? Something to keep an eye on.
In the meanwhile, we have a new (but very unrealistic) example
demonstrating the tangling directives.
There's still a big constraint on ordering: before/after clauses have to
come before functions that need them.
