and do not run template_candidate in the upper layers when the
template attribute is given.
This means we can use an over-approximation in the upper layer
implementation of template_candidate (returning false even in cases
which the kernel may accept) if we ever want to.

Using the parameter universes in the constructor causes implicit
equality constraints, so those universes may not be template
polymorphic.
A couple types in the stdlib were erroneously marked template, which
is now detected. Removing the marking doesn't actually change
behaviour though.
Also fixes #10504.

Reduction.whd_all does not commute with to_constr.

The code is self-contained and only used by commands; this also
highlights the several `Libobject.obj` registered for each
declaration.

This could be Prop (for compat with usual Coq), Set (for HoTT),
or actually an arbitrary "i".
Take lower bound of universes into account in pretyping/engine
Reinstate proper elaboration of SProp <= l constraints:
replacing is_small with equality with lbound is _not_ semantics preserving!
lbound = Set
Elaborate template polymorphic inductives with lower bound Prop
This will make more constraints explicit
Check univ constraints with Prop as lower bound for template inductives
Restrict template polymorphic universes to those not bounded from below
Fixes #9294
fix suggested by Matthieu
Try second fix suggested by Matthieu
Take care of modifying elaboration for record declarations as well.
Rebase and export functions for debug
Remove exported functions used while debugging
Add a new typing flag "check_template" and option "-no-template-checl"
This parameterizes the new criterion on template polymorphic inductives
to allow bypassing it (necessary for backward compatibility).
Update checker to the new typing flags structure
Switch on the new template_check flag to allow old unsafe behavior in
indTyping.
This is the only change of code really impacting the kernel, together
with the commit implementing unbounded from below and parameterization
by the lower bound on universes.
Add deprecated option `Unset Template Check` allowing to make proof
scripts work with both 8.9 and 8.10 for a while
Fix `Template Check` option name and test it
Add `Unset Template Check` to Coq89.v
Cooking of inductives and template-check tests
Cleanup test-suite file for template check / universes(template) flags
cookind tests
Move test of `Unset Template Check` to the failure/ dir, but comment it
for now
Template test-suite test explanation
Overlays for PR 9918
Overlay for paramcoq
Add overlay for fiat_parsers (-no-template-check)
Add overlay for fiat_crypto_legacy
Update fiat-crypto legacy overlay
Now it points at the version that I plan on merging; I am hoping that doing this will guard against mistakes by adding an extra check that the target tested by Coq's CI on this branch works with the change I made.
Remove overlay that should no longer be necessary
The setting in the compat file should handle it
Remove now-merged fiat-crypto-legacy overlay
Update `Print Assumptions` to reflect the typing flag for template checking
Fix About and Print Assumptions for template poly, giving info on which
variables are actually polymorphic
Fix pretty printing to print global universe levels properly
Fix printing of template polymorphic universes
Fix pretty printing for template polymorphism on no universe
Fix interaction of template check and universes(template) flag
Fix indTyping to really check if there is any point in polymorphism: the
conclusion sort should be parameterized over at least one local universe
Indtyping fixes for template polymorphic Props
Allow explicit template polymorphism again
Adapt to new indTyping interface
Handle the case of template-polymorphic on no universes
correctly (morally Type0m univ represented as Prop).
Fix check of meaningfullness of template polymorphism in the kernel.
It is now done w.r.t the min_univ, the minimal universe inferred for the
inductive/record type, independently of the user-written annotation
which must only be larger than min_univ. This preserves compatibility
with UniMath and template-polymorphism as it has been implemented up-to
now.
Comment on identity non-template-polymorphism
Remove incorrect universes(template) attributes from ssr
simpl_fun can be meaningfully template-poly, as well as
pred_key (although the use is debatable: it could just
as well be in Prop).
Move `fun_of_simpl` coercion declaration out of section to respect
uniform inheritance
Remove incorrect uses of #[universes(template)] from the stdlib
Extraction of micromega changes due to moving an ind decl out of a section
Remove incorrect uses of #[universes(template)] from plugins

Remove overlays as they have been merged upstream.

This lets us remove the passing around of "status" in comassumption
and generally makes highlighting axiom adding lines in coqide more
reliable as there's no need for per-command code.
If a command adds multiple axioms it will emit AddedAxiom multiple
times, this doesn't seem to be a problem though.
We may wonder if "Fail Fail Axiom" should be highlighted as
"Axiom" (both before and after this commit it is).

The internal interpretation functions have been not used by funind
since some time.

Not pretty, but it had to be done some day, as `Globnames` seems to be
on the way out.
I have taken the opportunity to reduce the number of `open` in the
codebase.
The qualified style would indeed allow us to use a bit nicer names
`GlobRef.Inductive` instead of `IndRef`, etc... once we have the
tooling to do large-scale refactoring that could be tried.
|

We remove two flags that were seldom used in favor of named parameters.
|
|
|
|
This is more in-line with attributes and the rest of the API, and
makes some code significantly clearer (as in `foo true false false`,
etc...)

Conversely, Type existential variables now (explicitly) cover the Set
case.
Similarly for Prop and SProp.

We consistently use:
- UUnknown: to mean a rigid anonymous universe
(written Type in instances and Type as a sort)
[was formerly encoded as [] in Type's argument]
- UAnonymous: to mean a flexible anonymous universe
(written _ in instances and Type@{_} as a sort)
[was formerly encoded as [None] in Type's argument]
- UNamed: to mean a named universe or universe expression
(written id or qualid in instances and Type@{id} or Type@{qualid} or more
generally Type@{id+n}, Type@{qualid+n}, Type@{max(...)} as a sort)
There is a little change of syntax: "_" in a "max" list of universes
(e.g. "Type@{max(_,id+1)}" is not anymore allowed. But it was
trivially satisfiable by unifying the flexible universe with a
neighbor of the list and the syntax is anyway not documented.
There is a little change of semantics: if I do id@{Type} for an
abbreviation "id := Type", it will consider a rigid variable rather
than a flexible variable as before.

For nonsquashed:
Either
- 0 constructors
- primitive record
|
|
Kernel should be mostly correct, higher levels do random stuff at
times.
|

|

|

I think the usage looks cleaner this way.
|
|
We remove all calls to `Flags.is_program_mode` except one (to compute
the default value of the attribute). Everything else is passed
explicitely, and we remove the special logic in the interpretation loop
to set/unset the flag.
This is especially important since the value of the flag has an impact on
proof modes, so on the separation of parsing and execution phases.
|
|
This makes it print the warning before the definition message, so if
we run with +non-primitive-record we don't see
"""
defined foo
error could not define foo
"""
|

|
The situation is too unclear to make it of general use, plus it has
some issues (#9296)
I'm not deleting the warning as it can still be useful to find which
types are template for those who want to experiment.
|
|
The warning can be avoided with the attributes, (or just disable the
warning itself I guess).

This is a pre-requisite to use automated formatting tools such as
`ocamlformat`, also, there were quite a few places where the comments
had basically no effect, thus it was confusing for the developer.
p.s: Reading some comments was a lot of fun :)

In general, `Nametab` is not a module you want to open globally as it
exposes very generic identifiers such as `push` or `global`.
Thus, we remove all global opens and qualify `Nametab` access. The
patch is small and confirms the hypothesis that `Nametab` access
happens in few places thus it doesn't need a global open.
It is also very convenient to be able to use `grep` to see accesses to
the namespace table.

This doesn't change behaviour currently as the kernel also makes this
decision, but in the future it won't.

Closes #7967.

Don't allow notations attached to uniform inductives

reference was defined as Ident or Qualid, but the qualid type already
permits empty paths. So we had effectively two representations for
unqualified names, that were not seen as equal by eq_reference.
We remove the reference type and replace its uses by qualid.
