* Cleanup API for registering universe binders.Gravatar Matthieu Sozeau2017-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Regularly declared for for polymorphic constants - Declared globally for monomorphic constants. E.g mono@{i} := Type@{i} is printed as mono@{mono.i} := Type@{mono.i}. There can be a name clash if there's a module and a constant of the same name. It is detected and is an error if the constant is first but is not detected and the name for the constant not registered (??) if the constant comes second. Accept VarRef when registering universe binders Fix two problems found by Gaëtan where binders were not registered properly Simplify API substantially by not passing around a substructure of an already carrier-around structure in interpretation/declaration code of constants and proofs Fix an issue of the stronger restrict universe context + no evd leak This is uncovered by not having an evd leak in interp_definition, and the stronger restrict_universe_context. This patch could be backported to 8.7, it could also be triggered by the previous restrict_context I think.

| * Use Entries.constant_universes_entry more.Gravatar Gaëtan Gilbert2017-11-24
| | | | | | | | | | | | This reduces conversions between ContextSet/UContext and encodes whether we are polymorphic by which constructor we use rather than using some boolean.
| * When declaring constants/inductives use ContextSet if monomorphic.Gravatar Gaëtan Gilbert2017-11-24
| | | | | | | | | | | | | | | | Also use constant_universes_entry instead of a bool flag to indicate polymorphism in ParameterEntry. There are a few places where we convert back to ContextSet because check_univ_decl returns a UContext, this could be improved.
| * Stop exposing UState.universe_context and its Evd wrapper.Gravatar Gaëtan Gilbert2017-11-24
| | | | | | | | | | | | 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).

* [api] Deprecate Term destructors, move to ConstrGravatar Emilio Jesus Gallego Arias2017-11-22

* [proof] Attempt to deprecate some V82 parts of the proof API.Gravatar Emilio Jesus Gallego Arias2017-11-19
| | | | | | | | | | | | I followed what seems to be the intention of the code, with the original intention of remove the global imperative proof state. However, I fully fail to see why the new API is better than the old one. In fact the opposite seems the contrary. Still big parts of the "new proof engine" seem unfinished, and I'm afraid I am not the right person to know what direction things should take.

* [stm] Remove state-handling from Futures.Gravatar Emilio Jesus Gallego Arias2017-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We make Vernacentries.interp functional wrt state, and thus remove state-handling from `Future`. Now, a future needs a closure if it wants to preserve state. Consequently, `Vernacentries.interp` takes a state, and returns the new one. We don't explicitly thread the state in the STM yet, instead, we recover the state that was used before and pass it explicitly to `interp`. I have tested the commit with the files in interactive, but we aware that some new bugs may appear or old ones be made more apparent. However, I am confident that this step will improve our understanding of bugs. In some cases, we perform a bit more summary wrapping/unwrapping. This will go away in future commits; informal timings for a full make: - master: real 2m11,027s user 8m30,904s sys 1m0,000s - no_futures: real 2m8,474s user 8m34,380s sys 0m59,156s
* [vernac] Remove "Proof using" hacks from parser.Gravatar Emilio Jesus Gallego Arias2017-10-10
| | | | | | | | | We place `Proof_using` in the proper place [`vernac`] and we remove gross parsing hacks. The new placement should allow to use the printers and more convenient structure, and reduce strange coupling between parsing and internal representation.
* Take Suggest Proof Using outside the kernel.Gravatar Gaëtan Gilbert2017-10-10
| | | | | | | | | | | | | | | | | | | Also add an output test for Suggest Proof Using. This changes the .aux output: instead of getting a key >context_used "$hyps;$suggest" where $hyps is a list of the used hypotheses and $suggest is the ;-separated suggestions (or the empty string if Suggest Proof Using is unset), there is a key >context_used "$hyps" and if Suggest Proof Using is set also a key >suggest_proof_using "$suggest" For instance instead of 112 116 context_used "B A;A B;All" we get 112 116 context_used "B A" 112 116 suggest_proof_using "A B;All"

* Allow declaring universe constraints at definition level.Gravatar Matthieu Sozeau2017-09-19
| | | | | | | | | | | | | | 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.
* Fix a refine anomaly "Evar defined twice".Gravatar Pierre-Marie Pédrot2017-09-06

* | [api] Put modules in order in API.{mli,ml}Gravatar Emilio Jesus Gallego Arias2017-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We sort the dependency graph of API by following a logical declaration order in `API.{ml,mli}` related to the actual dependency order of Coq modules. Things are a bit tricky here as Coq itself relies on the fact that OCaml treats module interface and implementation separately dependency-wise; however, when resorting module alias the design seems to become more coupled. Currently, API exposes both "namespaces", asserting a large number of type equality between them, however the `API` namespace is not self-contained. In particular, this is a first step to solve problems such as `Summary.frozen` being used in `API.mli` but not declared by the `API.Summary` module, etc... In general we follow the invariant that a type used in `API` must have been declared before. Keep in mind that OCaml upstream has warned that it maybe tricky to alias objects in this way. In particular, after API the old `mli` only files have become full compilation units so we may want to be more careful here. The more "correct" declaration order allows us to remove the `API.Prelude` module, as well as some other declarations that I consider as spurious. We still maintain the large number of type aliases which will be removed in a future patch. We follow linking order except for files in `intf`, which are conceptually wrongly placed in the linking hierarchy but this doesn't matter as the files don't contain any implementation. We also move a couple of `.mli` only files to `.ml` so we are consistent, and correct their linking order in `mllib`, even if that doesn't matter as such `.ml`-only files contain no implementations.

In some cases this could be refined but we don't do anything fancy, we just reflect the status quo.
