2017-02-17Ltac as a plugin.Pierre-Marie Pédrot
This commit is essentially moving files around. In particular, the corresponding plugin still relies on a mllib file rather than a mlpack one. Otherwise, this causes link-time issues for third-party plugins depending on modules defined in the Ltac plugin.

2016-11-03Lets Hints/Instances take an optional patternMatthieu Sozeau
In addition to a priority, cleanup the interfaces for passing this information as well. The pattern, if given, takes priority over the inferred one. We only allow Existing Instances gr ... gr | pri. for now, without pattern, as before. Make the API compatible to 8.5 as well.

2016-09-22Revert "Merge remote-tracking branch 'github/pr/283' into trunk"Maxime Dénès
I hadn't realized that this PR uses OCaml's 4.03 inlined records feature. I will advocate again for a switch to the latest OCaml stable version, but meanwhile, let's revert. Sorry for the noise. This reverts commit 3c47248abc27aa9c64120db30dcb0d7bf945bc70, reversing changes made to ceb68d1d643ac65f500e0201f61e73cf22e6e2fb.
2016-09-20Stylistic improvements in intf/decl_kinds.mli.Maxime Dénès
We get rid of tuples containing booleans (typically for universe polymorphism) by replacing them with records. The previously common idom: if pi2 kind (* polymorphic *) then ... else ... becomes: if kind.polymorphic then ... else ... To make the construction and destruction of these records lightweight, the labels of boolean arguments for universe polymorphism are now usually also called "polymorphic".

2016-09-09Fix bug #3920 for good after 44ada64.Pierre-Marie Pédrot
The previous commit did not apply the beta reduction for compatibility on the correct goal. We rather apply it on the first generated subgoal. This fixes the ergo contrib.

2016-08-30Fix bug #3920: eapply masks an hypothesis name.Pierre-Marie Pédrot
The problem came from the fact that the legacy beta-reduction occurring after a rewrite was wrongly applied to the side-conditions of the rewriting step. We restrict it to the correct goal in this patch.
2016-08-30CLEANUP: switching from "right-to-left" to "left-to-right" function ↵Matej Kosik
composition operator. Short story: This pull-request: (1) removes the definition of the "right-to-left" function composition operator (2) adds the definition of the "left-to-right" function composition operator (3) rewrites the code relying on "right-to-left" function composition to rely on "left-to-right" function composition operator instead. Long story: In mathematics, function composition is traditionally denoted with ∘ operator. Ocaml standard library does not provide analogous operator under any name. Batteries Included provides provides two alternatives: _ % _ and _ %> _ The first operator one corresponds to the classical ∘ operator routinely used in mathematics. I.e.: (f4 % f3 % f2 % f1) x ≜ (f4 ∘ f3 ∘ f2 ∘ f1) x We can call it "right-to-left" composition because: - the function we write as first (f4) will be called as last - and the function write as last (f1) will be called as first. The meaning of the second operator is this: (f1 %> f2 %> f3 %> f4) x ≜ (f4 ∘ f3 ∘ f2 ∘ f1) x We can call it "left-to-right" composition because: - the function we write as first (f1) will be called first - and the function we write as last (f4) will be called last That is, the functions are written in the same order in which we write and read them. I think that it makes sense to prefer the "left-to-right" variant because it enables us to write functions in the same order in which they will be actually called and it thus better fits our culture (we read/write from left to right).
2016-08-24CLEANUP: minor readability improvementsMatej Kosik
mainly concerning referring to "Context.{Rel,Named}.get_{id,value,type}" functions. 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.

2016-08-19Remove errorlabstrm in favor of user_errEmilio Jesus Gallego Arias
As noted by @ppedrot, the first is redundant. The patch is basically a renaming. We didn't make the component optional yet, but this could happen in a future patch.

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.
