* | Remove the Sigma (monotonous state) API.Gravatar Maxime Dénès2017-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reminder of (some of) the reasons for removal: - Despite the claim in sigma.mli, it does *not* prevent evar leaks, something like: fun env evd -> let (evd',ev) = new_evar env evd in (evd,ev) will typecheck even with Sigma-like type annotations (with a proof of reflexivity) - The API stayed embryonic. Even typing functions were not ported to Sigma. - Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly less unsafe ones (e.g. s_enter), but those ones were not marked unsafe at all (despite still being so). - There was no good story for higher order functions manipulating evar maps. Without higher order, one can most of the time get away with reusing the same name for the updated evar map. - Most of the code doing complex things with evar maps was using unsafe casts to sigma. This code should be fixed, but this is an orthogonal issue. Of course, this was showing a nice and elegant use of GADTs, but the cost/benefit ratio in practice did not seem good.
| * Added support for a side effect on constants in reduction functions.Gravatar Thomas Sibut-Pinote2017-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This exports two functions: - declare_reduction_effect: to declare a hook to be applied when some constant are visited during the execution of some reduction functions (primarily cbv, but also cbn, simpl, hnf, ...). - set_reduction_effect: to declare a constant on which a given effect hook should be called. Developed jointly by Thomas Sibut-Pinote and Hugo Herbelin. Added support for printing effect in functions of tacred.ml.

* [cleanup] Unify all calls to the error function.Gravatar Emilio Jesus Gallego Arias2017-05-27
| | | | | | | | | | | | | This is the continuation of #244, we now deprecate `CErrors.error`, the single entry point in Coq is `user_err`. The rationale is to allow for easier grepping, and to ease a future cleanup of error messages. In particular, we would like to systematically classify all error messages raised by Coq and be sure they are properly documented. We restore the two functions removed in #244 to improve compatibility, but mark them deprecated.
* Using delayed universe instances in EConstr.Gravatar Pierre-Marie Pédrot2017-04-01
| | | | | | The transition has been done a bit brutally. I think we can still save a lot of useless normalizations here and there by providing the right API in EConstr. Nonetheless, this is a first step.
* Namegen primitives now apply on evar constrs.Gravatar Pierre-Marie Pédrot2017-02-14
| | | | | | Incidentally, this fixes a printing bug in output/inference.v where the displayed name of an evar was the wrong one because its type was not evar-expanded enough.
* Definining EConstr-based contexts.Gravatar Pierre-Marie Pédrot2017-02-14
| | | | | | This removes quite a few unsafe casts. Unluckily, I had to reintroduce the old non-module based names for these data structures, because I could not reproduce easily the same hierarchy in EConstr.

If multiple modules define a function with a same name, e.g.: Context.{Rel,Named}.get_type those calls were prefixed with a corresponding prefix to make sure that it is obvious which function is being called.

* Separate flags for fix/cofix/match reduction and clean reduction function names.Gravatar Maxime Dénès2016-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a reimplementation of Hugo's PR#117. We are trying to address the problem that the name of some reduction functions was not saying what they were doing (e.g. whd_betadeltaiota was doing let-in reduction). Like PR#117, we are careful that no function changed semantics without changing the names. Porting existing ML code should be a matter of renamings a few function calls. Also, we introduce more precise reduction flags fMATCH, fFIX, fCOFIX collectively denominated iota. We renamed the following functions: Closure.betadeltaiota -> Closure.all Closure.betadeltaiotanolet -> Closure.allnolet Reductionops.beta -> Closure.beta Reductionops.zeta -> Closure.zeta Reductionops.betaiota -> Closure.betaiota Reductionops.betaiotazeta -> Closure.betaiotazeta Reductionops.delta -> Closure.delta Reductionops.betalet -> Closure.betazeta Reductionops.betadelta -> Closure.betadeltazeta Reductionops.betadeltaiota -> Closure.all Reductionops.betadeltaiotanolet -> Closure.allnolet Closure.no_red -> Closure.nored Reductionops.nored -> Closure.nored Reductionops.nf_betadeltaiota -> Reductionops.nf_all Reductionops.whd_betadelta -> Reductionops.whd_betadeltazeta Reductionops.whd_betadeltaiota -> Reductionops.whd_all Reductionops.whd_betadeltaiota_nolet -> Reductionops.whd_allnolet Reductionops.whd_betadelta_stack -> Reductionops.whd_betadeltazeta_stack Reductionops.whd_betadeltaiota_stack -> Reductionops.whd_all_stack Reductionops.whd_betadeltaiota_nolet_stack -> Reductionops.whd_allnolet_stack Reductionops.whd_betadelta_state -> Reductionops.whd_betadeltazeta_state Reductionops.whd_betadeltaiota_state -> Reductionops.whd_all_state Reductionops.whd_betadeltaiota_nolet_state -> Reductionops.whd_allnolet_state Reductionops.whd_eta -> Reductionops.shrink_eta Tacmach.pf_whd_betadeltaiota -> Tacmach.pf_whd_all Tacmach.New.pf_whd_betadeltaiota -> Tacmach.New.pf_whd_all And removed the following ones: Reductionops.whd_betaetalet Reductionops.whd_betaetalet_stack Reductionops.whd_betaetalet_state Reductionops.whd_betadeltaeta_stack Reductionops.whd_betadeltaeta_state Reductionops.whd_betadeltaeta Reductionops.whd_betadeltaiotaeta_stack Reductionops.whd_betadeltaiotaeta_state Reductionops.whd_betadeltaiotaeta They were unused and having some reduction functions perform eta is confusing as whd_all and nf_all don't do it.

| * CLEANUP: Context.{Rel,Named}.Declaration.tGravatar Matej Kosik2016-02-09

(that is the case of people who just started to read the source code) Merlin would tell you that the type of the value you are destructing by "match" is: 'a * 'b option * Constr.t (* worst-case scenario *) or Named.Name.t * Constr.t option * Constr.t (* best-case scenario (?) *) To me, this is akin to wearing an opaque veil. It is hard to figure out the meaning of the values you are looking at. In particular, it is hard to discover the connection between the value we are destructing above and the datatypes and functions defined in the "kernel/context.ml" file. In this case, the connection is there, but it is not visible (between the function above and the "Context" module). ------------------------------------------------------------------------ Now consider, what happens when the reader see the same function presented in the following form: let test_strict_disjunction n lc = Array.for_all_i (fun i c -> match (prod_assum (snd (decompose_prod_n_assum n c))) with | [LocalAssum (_,c)] -> isRel c && Int.equal (destRel c) (n - i) | _ -> false) 0 lc If the reader haven't seen "LocalAssum" before, (s)he can use Merlin to jump to the corresponding definition and learn more. In this case, the connection is there, and it is directly visible (between the function above and the "Context" module). (2) Also, if we already have the concepts such as: - local declaration - local assumption - local definition and we describe these notions meticulously in the Reference Manual, then it is a real pity not to reinforce the connection of the actual code with the abstract description we published.

* Safer typing primitives.Gravatar Pierre-Marie Pédrot2015-05-13
| | | | | | | | | | | | | | | | Some functions from pretyping/typing.ml and their derivatives were potential source of evarmap leaks, as they dropped their resulting evarmap. This commit clarifies the situation by renaming them according to a unsafe_* scheme. Their sound variant is likewise renamed to their old name. The following renamings were made. - Typing.type_of -> unsafe_type_of - Typing.e_type_of -> type_of - A new e_type_of function that matches the e_ prefix policy - Tacmach.pf_type_of -> pf_unsafe_type_of - A new safe pf_type_of function. All uses of unsafe_* functions should be eventually eliminated.
