Undo 3272. The trouble with creating a new section for constants is that
there's no good place to order it since constants can be initialized
using globals as well as vice versa. And I don't want to add constraints
disallowing either side.
Instead, a new plan: always declare constants in the Globals section
using 'extern const' rather than just 'const', since otherwise constants
implicitly have internal linkage (http://stackoverflow.com/questions/14894698/why-does-extern-const-int-n-not-work-as-expected)

The mu commandline now has four parts: options, commands (of which we
only have one so far: 'test'), files/directories and ingredients to pass
to 'main'. That cleans up the hacky ordering constraint we had earlier.
I've also cleaned up the usage message.

Fix a bug with --test-only-app: the "App tests" header was only printing
after some app tests had run.

Toss out Scenario_names. It's only checking if we load duplicate
scenarios, and we have independent checks for *running* duplicate
scenarios.
This has the salubrious effect of also allowing lessons to contain
regular text scenarios interspersed with their recipes.

Complicated logic to not run core tests. I only want to disable core
tests if:
a) I'm changing CFLAGS on the commandline (usually to disable
optimizations, causing tests to run slower in a debug cycle)
b) I'm not printing a help message (either with just 'mu' or
'mu --help')
c) I'm loading other files besides just the core.
Under these circumstances I only want to run tests in the files
explicitly loaded at the commandline.
This is all pretty hairy, in spite of my attempts to document it in
four different places. I might end up taking it all out the first time I
need to run core tests under all these conditions.

Always show instruction before any transforms in error messages.
This is likely going to make some errors unclear because they *need* to
show the original instruction. But if we don't have tests for those
situations did they ever really work?

Failures in scenarios should consistently trigger the summary message
showing number of failed tests.

I'd been toying with this idea for some time now given how large the
repo had been growing. The final straw was noticing that people cloning
the repo were having to wait *5 minutes*! That's not good, particularly
for a project with 'tiny' in its description. After purging .traces/
clone time drops to 7 seconds in my tests.
Major issue: some commits refer to .traces/ but don't really change
anything there. That could get confusing :/
Minor issues:
a) I've linked inside commits on GitHub like a half-dozen times online
or over email. Those links are now liable to eventually break. (I seem
to recall GitHub keeps them around as long as they get used at least
once every 60 days, or something like that.)
b) Numbering of commits is messed up because some commits only had
changes to the .traces/ sub-directory.

Standardize quotes around reagents in error messages.
I'm still sure there's issues. For example, the messages when
type-checking 'copy'. I'm not putting quotes around them because in
layer 60 I end up creating dilated reagents, and then it's a bit much to
have quotes and (two kinds of) brackets. But I'm sure I'm doing that
somewhere..
|

Long-overdue reorganization to support general 'dilated' reagents up
front. This also allows me to move tests that are really about unrelated
layers out of layers dealing with parsing.

This is hopefully quite thorough. I handle nested containers, as well as
exclusive containers that might contain addresses only when the tag has
a specific value.
|
| | |
|
| |
|
|
|
|
|
| |
Now that we no longer have non-shared addresses, we can just always
track refcounts for all addresses.
Phew!

Turns out one of my chessboard tests has been silently deadlocking and
therefore not actually checking its results since at least commit 1620
last June.

Show more thorough information about instructions in the trace, but keep
the original form in error messages.
|

This should eradicate the issue of 2771.

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.

Only Hide_errors when strictly necessary. In other places let test
failures directly show the unexpected error.

All my attempts at staging this change failed with this humongous commit
that took all day and involved debugging three monstrous bugs. Two of
the bugs had to do with forgetting to check the type name in the
implementation of shape-shifting recipes. Bug #2 in particular would
cause core tests in layer 59 to fail -- only when I loaded up edit/! It
got me to just hack directly on mu.cc until I figured out the cause
(snapshot saved in mu.cc.modified). The problem turned out to be that I
accidentally saved a type ingredient in the Type table during
specialization. Now I know that that can be very bad.
I've checked the traces for any stray type numbers (rather than names).
I also found what might be a bug from last November (labeled TODO), but
we'll verify after this commit.

Stack of plans for cleaning up replace_type_ingredients() and a couple
of other things, from main problem to subproblems:
include type names in the type_tree rather than in the separate properties vector
make type_tree and string_tree real cons cells, with separate leaf nodes
redo the vocabulary for dumping various objects:
do we really need to_string and debug_string?
can we have a version with *all* information?
can we have to_string not call debug_string?
This commit nibbles at the edges of the final task, switching from
member method syntax to global function like almost everything else. I'm
mostly using methods just for STL in this project.

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.

Reorganize layers in preparation for a better, more type-safe
implementation of first-class and higher-order recipes.

The idea is that to-text-line should truncate blindly past some
threshold, even if to-text isn't smart enough to avoid infinite loops.
Maybe I should define a 'truncating buffer' which stops once it fills
up. That would be an easy way to eliminate all infinite loops in
to-text-line.
|
| |
|
|
|
| |
'append' also implicitly calls 'to-text' unless there's a better
variant.

This is happening because of our recent generic changes, which trigger
some post-processing transforms on all recipes even if we processed them
before. We could clear 'interactive' inside 'reload' to avoid this, but
random 'run' blocks in scenarios can still pick up errors from sandboxes
earlier in a scenario. The right place to clear the 'interactive' recipe
is right after we use it, in run_code_end().
