2016-07-01Add and document match, fix and cofix reduction flags.Maxime Dénès
2016-07-01Separate flags for fix/cofix/match reduction and clean reduction function names.Maxime Dénès
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.
2016-07-01Fixing #4881 (synchronizing "Declare Implicit Tactic" with backtrack).Hugo Herbelin
2016-07-01Fixing #4882 (anomaly with Declare Implicit Tactic on hole of type with evars).Hugo Herbelin
But there are still bugs with Declare Implicit Tactic, which should probably rather be reimplemented with ltac:(tac). Indeed, it does support evars in the type of the term, and solve_by_implicit_tactic should transfer universe constraints to the main goal. E.g., the following still fails, at Qed time. Definition Foo {T}{a : T} : T := a. Declare Implicit Tactic eassumption. Goal forall A (x : A), A. intros. apply Foo. Qed.
2016-06-29A new infrastructure for warnings.Maxime Dénès
On the user side, coqtop and coqc take a list of warning names or categories after -w. No prefix means activate the warning, a "-" prefix means deactivate it, and "+" means turn the warning into an error. Special categories include "all", and "default" which contains the warnings enabled by default. We also provide a vernacular Set Warnings which takes the same flags as argument. Note that coqc now prints warnings. The name and category of a warning are printed with the warning itself. On the developer side, Feedback.msg_warning is still accessible, but the recommended way to print a warning is in two steps: 1) create it by: let warn_my_warning = CWarnings.create ~name:"my-warning" ~category:"my-category" (fun args -> Pp.strbrk ...) 2) print it by: warn_my_warning args

2016-06-12Another fix to #4782 (a typing error not captured when dealing with bindings).Hugo Herbelin
The tentative fix in f9695eb4b (which I was afraid it might be too strong, since it was implying failing more often) indeed broke other things (see #4813).
2016-06-11Fixing #4782 (a typing error not captured when dealing with bindings).Hugo Herbelin
Trying to now catch all unification errors, but without a clear view at whether some errors could be tolerated at the point of checking the type of the binding.

2016-05-31Feedback cleanupEmilio Jesus Gallego Arias
This patch splits pretty printing representation from IO operations. - `Pp` is kept in charge of the abstract pretty printing representation. - The `Feedback` module provides interface for doing printing IO. The patch continues work initiated for 8.5 and has the following effects: - The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`, `pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`, `msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be used instead. - Feedback provides different backends to handle output, currently, `stdout`, `emacs` and CoqIDE backends are provided. - Clients cannot specify flush policy anymore, thus `pp_flush` et al are gone. - `Feedback.feedback` takes an `edit_or_state_id` instead of the old mix. Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.
2016-05-26Pfedit.get_current_context refinement (fix #4523)Matthieu Sozeau
Return the most appropriate evar_map for commands that can run on non-focused proofs (like Check, Show and debug printers) so that universes and existentials are printed correctly (they are global to the proof). The API is backwards compatible.

2016-05-10Proof_global, STM: cleanup + use default_proof_mode instead of "Classic"Enrico Tassi
The "Classic" string is still hard coded here in there in the system, but not in STM. BTW, the use of an hard coded "Classic" value suggests nobody really uses "Set Default Proof Mode" in .v files.

Return an evar_map with the right universes, when there are no focused subgoals or the proof is finished.
2016-03-23Revert "refine: do check all unif problems are solved (Close: #4415, #4532)"Enrico Tassi
This fix is too restrictive. Still, opening a goal for an evar with a pending conv_pb is unsafe since the user may prove (instantiate it) in a way not compatible with the conv_pb. Assigning an evar, in its lowest level API, should enforce that all related conv_pbs are satisfied by the instance. This also poses a UI problem, since there is not way to see these conv_pbs. One could print a goal and say: look, the proof term you give must validate this equation... Given that the good fix is not obvious, we revert! This reverts commit a0e792236c9666df1069753f8f807c12f713dcfb.
2016-03-23refine: do check all unif problems are solved (Close: #4415, #4532)Enrico Tassi
This fixes a class of bugs like refine foo; tactic. where tactic fails (by resuming the remaining, unsolvable, problems) while in 8.4 refine was failing. It is not clear to us (Maxime and myself) if we should call consider_remaining_unif_problems instead of check_problems_are_solved.

2016-02-17CLEANUP: Renaming "Util.compose" function to "%"Matej Kosik
I propose to change the name of the "Util.compose" function to "%". Reasons: 1. If one wants to express function composition, then the new name enables us to achieve this goal easier. 2. In "Batteries Included" they had made the same choice.
