Finally terminate the experiment of keeping debug prints around. I'm
also going to give up on maintaining counts.
What we really need is two kinds of tracing:
a) For tests, just the domain-specific facts, organized by labels.
b) For debugging, just transient dumps to stdout.
b) only works if stdout is clean by default.
Hmm, I think this means 'stash' should be the transient kind of trace.

Right after I lectured Caleb about not just adding random deltas to make
a program correct, too.

Extend deadline for run-interactive.

This time I'm getting rid of all the intricate SCREEN hacking. Now
run-interactive is idiomatic: it creates a recipe on the fly, runs it,
and returns various results and stats about it.
One big consequence of the recipe now running interactively inside a
local-scope: you can't just use numeric addresses anymore -- not without
using /raw. Fixed one of the tests to reflect this.
I realize now that I don't really want my students to be using raw
addresses in their sandboxes, even if that was my idiom for lower-level
scenarios.
Hopefully running sandboxes in separate (synchronous) routines will be
easy now.

Still trying to minimize the work around run-interactive so I can build
it with a sandboxed routine rather than a call in editor space.

Thanks Caleb Couch.

More friendly way to 'stash' stuff in the trace so that you can toggle
lines of code to see their stashed traces.

Still iterating on the right way to handle incorrect number of
ingredients. My first idea of creating null results doesn't really work
once they're used in later instructions. Just add a warning at one place
in the run loop, but otherwise only add products when there's something
to save in them.
Undoes some work around commit 1886.

Region to click on to edit is now reduced to just the menu bar for the
sandbox (excluding the 'x' for deleting the sandbox). The symmetry there
might be useful, but we'll see if the relative click area is
in line with how commonly the actions are performed.

Generalize a little layer as a first step to providing traces for other
layers.
|

For example:
x:number <- index y:address:array:number, 3
(forgetting to do a lookup)
Thanks Caleb Couch.

Should be a little bit more mnemonic.

First step to reducing typing burden. Next step: inferring types.
|

|

Also standardized warnings.

Eventually we might be able to get rid of die entirely.
This is just a preliminary stab at a random error. In the process I ran
into two issues that have impeded debugging before:
a) Naming conflicts within scenarios are a real no-no. I need to warn on
them, but the rules are getting complicated:
Always print warnings on redefine
But not in interactive mode
Or in scenarios checking warning behavior
Unless the scenario recipe itself is overridden
b) Now that we've added collect_layers and a long time can go between
traces, debugging is a minefield because trace lines don't print to
screen immediately after they're created. Need to do something about
that. Maybe explicitly trigger collection by tracing '\n' or something.
These are the next two items on my todo list.

Things I figured out:
- 'row' in render-screen doesn't perfectly track cursor-row in screen
- proximal cause was forgetting to add left:number to stop-printing
- trying to print to screen outside bounds was silently succeeding and
corrupting simulated memory
- if we silently ignore prints outside bounds things are fine
But why are prints outside screen bounds working? We should be accessing
screen data using 'index', and that's checking its bounds.
|
| |
|
|
|
| |
Debugging simulated-screen support is taking too long, and I suddenly
have a few higher priorities.
|
| |
|
|
| |
I'm writing to location 'screen' somehow that's not the raw location.

Speeds up edit.mu tests by 10x, and shrinks memory usage by 100x.
We need a more efficient implementation of traces, but we can keep going
for now.
We didn't really need to reclaim memory just yet, after all. Mu is
pretty memory-efficient.
|
| |

Finally, albeit too late for my demo.

All tests passing, but early layers are broken.
|

This is starting to look good! I need to add some tests for
render-string, but we'll see.

Some reorg before we start plumbing 'reply' from 'run-interactive' to
return a string containing the results.

Also added another failing test showing what behavior we want in the
programming environment. But there's no way to make use of querying
locations, since we're not planning any interaction with individual
sandboxes at the moment.
Instead of interacting with one sandbox at a time, which is the current
approach, we want to create dashboards out of multiple sandboxes at
once. Start with them non-interactive, that'll demonstrate 80% of the
new benefits. We'll add interactivity down the road.

We will need many other forms of isolation for these. For starters we're
going to have to replace most asserts with warnings that can be traced
so that the environment doesn't crash because of illegal code typed into
it.
New test is still failing. Just getting it to fail right was hard
enough.
