We need to a partial restore. I think that we could design a better
API, but further work on the toplevel state should improve it
progressively.
|
|
|
|
There don't really bring anything, we also correct some minor nits
with the printing function.
|
|
|
|
This reduces conversions between ContextSet/UContext and encodes
whether we are polymorphic by which constructor we use rather than
using some boolean.
|
|
We can enforce properties through check_univ_decl, or get an arbitrary
ordered context with UState.context / Evd.to_universe_context (the
later being a new wrapper of the former).
|
|
|
|
Before sometimes there were lists and strings.
|
|
|
|
Note the problem with `create_evar_defs`.
|
|
|
|
We do up to `Term` which is the main bulk of the changes.
|
|
This will allow to merge back `Names` with `API.Names`

In particular, this fixes #5757 which used restrict_evar to refine the
information on the source of an evar, and which should have set the
"cleared" flag.
Also renaming flag "restricted" since it is not only about "clear".
I guess this is what we want in general, but I did not survey all uses
of restrict_evar so, maybe, this should be refined further.

We dont care about the order of the binder map ([map] in the code) so
no need to do tricky things with it.

evd: Move constrain_variables to an operation on UState
Necessary to check universe declarations correctly for deferred proofs
in particular.
|
|
Introduce a "+" modifier for universe and constraint declarations to
indicate that these can be extended in the final definition/proof. By
default [Definition f] is equivalent to [Definition f@{+|+}], i.e
universes can be introduced and constraints as well. For [f@{}] or
[f@{i j}], the constraints can be extended, no universe introduced, to
maintain compatibility with existing developments. Use [f@{i j | }] to
indicate that no constraint (nor universe) can be introduced. These
kind of definitions could benefit from asynchronous processing.
Declarations of universe binders and constraints also works for
monomorphic definitions.

|
Use an explicit label ~algebraic for make_flexible_variable as well.
|
|
|
|
This allows a better control on the name to give to an evar and, in
particular, to address the issue about naming produced by "epose
proof" in one of the comment of Zimmi48 at PR #248 (see file names.v).
Incidentally updating output of Show output test (evar numbers shifted).
|
|
Now it is a private field, locations are optional.
|
|
|
|
All functions where actually called with the second argument of the pending
problem being the current evar map. We simply remove this useless and
error-prone second component.

Universes are kept in normal form w.r.t. equality but not the <=
relation, so the previous check worked almost always but was actually
too strict! In cases like (max(Set,u) = u) when u is declared >= Set it
was failing to find an equality. Applying the KISS principle:
u = v <-> u <= v /\ v <= u.
Fix invariant breakage that triggered the discovery of the check_eq bug as well. No algebraic universes should appear in a term position (on the left of
a colon in a typing judgment), this was not the case when an algebraic
universe instantiated an evar that appeared in the term. We force their
universe variable status to change in refresh_universes to avoid this.
Fix ind sort inference: Use syntactic universe equality for inductive
sort inference instead of check_leq (which now correctly takes
constraints into account) and simplify code

For better error messages. The API change is
backwards compatible, using a new optional argument.

The structure of the Context module was refined in such a way that:
- Types and functions related to rel-context declarations were put into the Context.Rel.Declaration module.
- Types and functions related to rel-context were put into the Context.Rel module.
- Types and functions related to named-context declarations were put into the Context.Named.Declaration module.
- Types and functions related to named-context were put into the Context.Named module.
- Types and functions related to named-list-context declarations were put into Context.NamedList.Declaration module.
- Types and functions related to named-list-context were put into Context.NamedList module.
Some missing comments were added to the *.mli file.
The output of ocamldoc was checked whether it looks in a reasonable way.
"TODO: cleanup" was removed
The order in which are exported functions listed in the *.mli file was changed.
(as in a mature modules, this order usually is not random)
The order of exported functions in Context.{Rel,Named} modules is now consistent.
(as there is no special reason why that order should be different)
The order in which are functions defined in the *.ml file is the same as the order in which they are listed in the *.mli file.
(as there is no special reason to define them in a different order)
The name of the original fold_{rel,named}_context{,_reverse} functions was changed to better indicate what those functions do.
(Now they are called Context.{Rel,Named}.fold_{inside,outside})
The original comments originally attached to the fold_{rel,named}_context{,_reverse} did not full make sense so they were updated.
Thrown exceptions are now documented.
Naming of formal parameters was made more consistent across different functions.
Comments of similar functions in different modules are now consistent.
Comments from *.mli files were copied to *.ml file.
(We need that information in *.mli files because that is were ocamldoc needs it.
It is nice to have it also in *.ml files because when we are using Merlin and jump to the definion of the function,
we can see the comments also there and do not need to open a different file if we want to see it.)
When we invoke ocamldoc, we instruct it to generate UTF-8 HTML instead of (default) ISO-8859-1.
(UTF-8 characters are used in our ocamldoc markup)
"open Context" was removed from all *.mli and *.ml files.
(Originally, it was OK to do that. Now it is not.)
An entry to dev/doc/changes.txt file was added that describes how the names of types and functions have changed.
