Instead of trying to hint computations (buying us %memo, etc), we
simply pass through the nouns (with constant [1 noun] formulas)
to the underlying runtime. This avoids spuriously product-hinting
the +tone results of +mink as the previous version did.
When molds were changed to crash on bad input, mook was not updated.
It relied on the old behavior of bunting on bad input. +moko
(the replacement +mook) simply doesn't include stack items that don't
have the proper type (in constrast to +mook, which currently crashes
and used to leave a "blank"/bunted stack item for improperly typed
values).
+mink, the current virtual nock interpreter, has a couple of problems.
1. it propagates blocks as a list of paths, which is inconsistent with
the way the jet behaves (only a single path is ever blocked on, with
exception semantics).
2. +mush was not updated after the change to molds to crash instead of
bunting. it crashes when not given the right kind of data, which is
inconsistent with the intended semantics of ++mink.
3. it "eats" hints, causing (for example) slogs to disappear when running
without a mink jet.
4. the naming/style was typically cryptic. since +mink will never really
be run, one could argue that its primary purpose is to be read.
+mino (which will be renamed to +mink after some staging) has had its
return type (+tono, to be renamed +tone) modified in the block case so
that it only blocks on one path, has a corrected +mush, carefully
"passes through" all hints to the underlying interpreter, and has more
meaningful names, with the intention of improving readability.
A generator (gen/mino.hoon) is also included in this commit; it contains
tests that were used during the development of +mino. It should be removed
before integration, and is included for posterity. The stack trace semantics
are expected to change in the near future (since they are dependent on jets
faithfully preserving the stack pushes of the pure nock, an onerous burden).
They are, however, tested in gen/mino.hoon, which makes it unsuitable as a
long-term test.
This fixes +put:in so that it works without the correct jet. There's a
mismatch where the hoon code is wrong and the jet is correct, so that
when we try to run this on alternate interpreters which may not have the
+in jets, things won't work.
Immediately useful for implemeting json `@rd` parsing, which is basically
`++royl-rd` minus pfix sig. The increased separation also allows for running
stuff like `(rash '3.22e-47' royl-rn:so)` from the dojo.
This extends `gol` "backward-inference" typechecking to thread through
cores. Recall that `gol` is used exclusively for receiving more
specific error messages; these changes should have no effect on programs
which already compile successfully.
Before, this would type-fail on the second `|%`.
```
!:
^+ ^?
|%
++ foo *@ud
--
|%
++ foo
?: =(1 1)
2
%foo
--
```
With these changes, it gives a mint-nice at `%foo`. It will also give
you explicit errors if you have the wrong number/names of arms,
including which arms it expects.
This is becoming much more important with static gall, since it's the
first time we've used core subtyping so extensively and in userspace.
