Instead of setup() and teardown() we'll just use a reset() function from
now on, which will bring the machine back to a good state before each
test or run, and also before exit (to avoid memory leaks).
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)
Move global constants into their own section since we seem to be having
trouble linking in 'extern const' variables when manually cleaving mu.cc
into separate compilation units.
Clean up the Globals section so that we can generate extern declarations
for all globals out using this command after we carve it out into
globals.cc:
grep ';' globals.cc |perl -pwe 's/[=(].*/;/' |perl -pwe 's/^[^\/# ]/extern $&/' > globals.h
The first perl command strips out initializers. The second prepends
'extern'. This simplistic approach requires each global definition to
lie all on one line.
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.
Snapshot in switching editor-data.cursor to editor-data.before-cursor.
But I have trouble coercing events to touch events, even though using
the integer tag 2 for the conversion works.
I added one test to check that divide can return a float, then hacked at
the rippling failures across the entire entire codebase until all tests
pass. Now I need to look at the changes I made and see if there's a
system to them, identify other places that I missed, and figure out the
best way to cover all cases. I also need to show real rather than
encoded values in the traces, but I can't use value() inside reagent
methods because of the name clash with the member variable. So let's
take a snapshot before we attempt any refactoring. This was non-trivial
to get right.
Even if I convince myself that I've gotten it right, I might back this
all out if I can't easily *persuade others* that I've gotten it right.
