* [api] Misctypes removal: tactic flags.Gravatar Emilio Jesus Gallego Arias2018-06-12
| | | | | We move the "flag types" to its use place, and mark some arguments with named parameters better.
* [api] Rename `global_reference` to `GlobRef.t` to follow kernel style.Gravatar Emilio Jesus Gallego Arias2018-05-04
| | | | | | | | | | | | | In #6092, `global_reference` was moved to `kernel`. It makes sense to go further and use the current kernel style for names. This has a good effect on the dependency graph, as some core modules don't depend on library anymore. A question about providing equality for the GloRef module remains, as there are two different notions of equality for constants. In that sense, `KerPair` seems suspicious and at some point it should be looked at.
* [api] Move bullets and goals selectors to `proofs/`Gravatar Emilio Jesus Gallego Arias2018-05-01
| | | | | | | | | | `Vernacexpr` lives conceptually higher than `proof`, however, datatypes for bullets and goal selectors are in `Vernacexpr`. In particular, we move: - `proof_bullet`: to `Proof_bullet` - `goal_selector`: to a new file `Goal_select`
* Adding tacticals tclBINDFIRST/tclBINDLAST.Gravatar Hugo Herbelin2018-03-27
| | | | | | Design choice: Failing with an anomaly or with a catchable Ltac error "Fail": we fail with a Fail as it was the case with the related constrained version of tclTHENFIRST/tclTHENLAST.

* [engine] Remove ghost parameter from `Proofview.Goal.t`Gravatar Emilio Jesus Gallego Arias2018-02-12
| | | | | | | | | | | | | | In current code, `Proofview.Goal.t` uses a phantom type to indicate whether the goal was properly substituted wrt current `evar_map` or not. After the introduction of `EConstr`, this distinction should have become unnecessary, thus we remove the phantom parameter from `'a Proofview.Goal.t`. This may introduce some minor incompatibilities at the typing level. Code-wise, things should remain the same. We thus deprecate `assume`. In a next commit, we will remove normalization as much as possible from the code.

* 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.

| * Fix the API of the new pf_constr_of_global.Gravatar Pierre-Marie Pédrot2017-04-24
| | | | | | | | | | | | The current implementation was still using continuation passing-style, and furthermore was triggering a focus on the goals. We take advantage of the tactic features instead.
| * Removing the tclWEAK_PROGRESS tactical.Gravatar Pierre-Marie Pédrot2017-04-24
| | | | | | | | | | | | The only remaining use was applied on the unfold tactic, and the behaviours of tclPROGRESS and tclWEAK_PROGRESS coincide whenever only one goal is produced by their argument tactic.

* Using delayed universe instances in EConstr.Gravatar Pierre-Marie Pédrot2017-04-01

* | Removing most nf_enter in tactics.Gravatar Pierre-Marie Pédrot2017-02-14

* | Do not ask for a normalized goal to get hypotheses and conclusions.Gravatar Pierre-Marie Pédrot2017-02-14
| | | | | | | | | | This is now useless as this returns evar-constrs, so that all functions acting on them should be insensitive to evar-normalization.
* | 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.

| | | | | | | | | | | | | | | | | | | | The length of the pattern should now be exactly the number of assumptions and definitions introduced by the destruction or induction, including the induction hypotheses in case of an induction. Like for pattern-matching, the local definitions in the argument of the constructor can be skipped in which case a name is automatically created for these.

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.
* | | Tentative API fix for tactic arguments to be fed to tclWITHHOLES.Gravatar Pierre-Marie Pédrot2015-12-27
|/ / | | | | | | | | | | | | | | | | | | | | The previous implementation was a source of evar leaks if misused, as it created values coming together with their current evar_map. This is dead wrong if the value is not used on the spot. To fix this, we rather return a ['a delayed_open] object. Two argument types were modified: bindings and constr_bindings. The open_constr argument should also be fixed, but it is more entangled and thus I leave it for another commit.
* / Indexing Proofview.goals with a stage.Gravatar Pierre-Marie Pédrot2015-10-20

* Getting rid of Exninfo hacks.Gravatar Pierre-Marie Pédrot2014-12-16
| | | | | | | | | | | | | | | | | | | | Instead of modifying exceptions to wear additional information, we instead use a dedicated type now. All exception-using functions were modified to support this new type, in particular Future's fix_exn-s and the tactic monad. To solve the problem of enriching exceptions at raise time and recover this data in the try-with handler, we use a global datastructure recording the given piece of data imperatively that we retrieve in the try-with handler. We ensure that such instrumented try-with destroy the data so that there may not be confusion with another exception. To further harden the correction of this structure, we also check for pointer equality with the last raised exception. The global data structure is not thread-safe for now, which is incorrect as the STM uses threads and enriched exceptions. Yet, we splitted the patch in two parts, so that we do not introduce dependencies to the Thread library immediatly. This will allow to revert only the second patch if ever we switch to OCaml-coded lightweight threads.
* Add Ltac syntax for the [tclIFCATCH] primitive.Gravatar Arnaud Spiwack2014-12-12
| | | | [tryif t then t2 else t3] behaves like [t;t2] if [t] has at least one success, or [t3] otherwise. It generalises [t||t3] as failures from [t2] will not be caught.
* Constructor tactics backtracking is done using [Tacticals.New] rather than ↵Gravatar Arnaud Spiwack2014-12-08
| | | | | | | | | [Proofview]. The primitives in [Tacticals] respect Ltac's error level, whereas the one in [Proofview] do not necessarily. In that case the error caught was ignored causing arbitrary error level after [constructor] to be canceled. Needed the addition of an [ORD] variant to [OR] in [Tacticals.New] to avoid unnecessary precomputation (the 'D' stands for 'delay'). Fixes #3838.
