* Arith: full integration of the "Numbers" modular frameworkGravatar Pierre Letouzey2014-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The earlier proof-of-concept file NPeano (which instantiates the "Numbers" framework for nat) becomes now the entry point in the Arith lib, and gets renamed PeanoNat. It still provides an inner module "Nat" which sums up everything about type nat (functions, predicates and properties of them). This inner module Nat is usable as soon as you Require Import Arith, or just Arith_base, or simply PeanoNat. - Definitions of operations over type nat are now grouped in a new file Init/Nat.v. This file is meant to be used without "Import", hence providing for instance Nat.add or Nat.sqrt as soon as coqtop starts (but no proofs about them). - The definitions that used to be in Init/Peano.v (pred, plus, minus, mult) are now compatibility notations (for Nat.pred, Nat.add, Nat.sub, Nat.mul where here Nat is Init/Nat.v). - This Coq.Init.Nat module (with only pure definitions) is Include'd in the aforementioned Coq.Arith.PeanoNat.Nat. You might see Init.Nat sometimes instead of just Nat (for instance when doing "Print plus"). Normally it should be ok to just ignore these "Init" since Init.Nat is included in the full PeanoNat.Nat. I'm investigating if it's possible to get rid of these "Init" prefixes. - Concerning predicates, orders le and lt are still defined in Init/Peano.v, with their notations "<=" and "<". Properties in PeanoNat.Nat directly refer to these predicates in Peano. For instantation reasons, PeanoNat.Nat also contains a Nat.le and Nat.lt (defined via "Definition le := Peano.le", we cannot yet include an Inductive to implement a Parameter), but these aliased predicates won't probably be very convenient to use. - Technical remark: I've split the previous property functor NProp in two parts (NBasicProp and NExtraProp), it helps a lot for building PeanoNat.Nat incrementally. Roughly speaking, we have the following schema: Module Nat. Include Coq.Init.Nat. (* definition of operations : add ... sqrt ... *) ... (** proofs of specifications for basic ops such as + * - *) Include NBasicProp. (** generic properties of these basic ops *) ... (** proofs of specifications for advanced ops (pow sqrt log2...) that may rely on proofs for + * - *) Include NExtraProp. (** all remaining properties *) End Nat. - All other files in directory Arith are now taking advantage of PeanoNat : they are now filled with compatibility notations (when earlier lemmas have exact counterpart in the Nat module) or lemmas with one-line proofs based on the Nat module. All hints for database "arith" remain declared in these old-style file (such as Plus.v, Lt.v, etc). All the old-style files are still Require'd (or not) by Arith.v, just as before. - Compatibility should be almost complete. For instance in the stdlib, the only adaptations were due to .ml code referring to some Coq constant name such as Coq.Init.Peano.pred, which doesn't live well with the new compatibility notations.

* ZArith + other : favor the use of modern names instead of compat notationsGravatar letouzey2012-07-05
| | | | | | | | | | | | | | | | | | - For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 85f007b7-540e-0410-9357-904b9bb8a0f7
* Cleanup of files related with power over Z.Gravatar letouzey2011-07-01
| | | | | | | | | | | | | | - Zpow_def, Zpower, Zpow_facts shortened thanks to stuff in BinInt.Z - The alternative Zpower_alt is now in a separate file Zpow_alt.v, not loaded by default. - Some more injection lemmas in Znat (pow, div, mod, quot, rem) - Btw, added a "square" function in Z, N, Pos, ... (instead of Zpow_facts.Zsquare). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14253 85f007b7-540e-0410-9357-904b9bb8a0f7
* A fine-grain control of inlining at functor application via priority levelsGravatar letouzey2011-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As said in CHANGES: << The inlining done during application of functors can now be controlled more precisely. In addition to the "!F G" syntax preventing any inlining, we can now use a priority level to select parameters to inline : "<30>F G" means "only inline in F the parameters whose levels are <= 30". The level of a parameter can be fixed by "Parameter Inline(30) foo". When levels aren't given, the default value is 100. One can also use the flag "Set Inline Level ..." to set a level. >> Nota : the syntax "Parameter Inline(30) foo" is equivalent to "Set Inline Level 30. Parameter Inline foo.", and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G." For instance, in ZBinary, eq is @Logic.eq and should rather be inlined, while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined. We could achieve this behavior by setting a level such as 30 to the parameter eq, and then tweaking the current level when applying functors. This idea of levels might be too restrictive, we'll see, but at least the implementation of this change was quite simple. There might be situation where parameters cannot be linearly ordered according to their "inlinablility". For these cases, we would need to mention names to inline or not at a functor application, and this is a bit more tricky (and might be a pain to use if there are many names). No documentation for the moment, since this feature is experimental and might still evolve. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13807 85f007b7-540e-0410-9357-904b9bb8a0f7
* Numbers : also axiomatize constants 1 and 2.Gravatar letouzey2010-10-14
| | | | | | | | | | | | | | | | | Initially, I was using notation 1 := (S 0) and so on. But then, when implementing by NArith or ZArith, some lemmas statements were filled with Nsucc's and Zsucc's instead of 1 and 2's. Concerning BigN, things are rather complicated: zero, one, two aren't inlined during the functor application creating BigN. This is deliberate, at least for the other operations like BigN.add. And anyway, since zero, one, two are defined too early in NMake, we don't have 0%bigN in the body of BigN.zero but something complex that reduce to 0%bigN, same for one and two. Fortunately, apply or rewrite of generic lemmas seem to work, even if there's BigZ.zero on one side and 0 on the other... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13555 85f007b7-540e-0410-9357-904b9bb8a0f7

* Diamond-shape instead of linear hiearchy in Numbers/NatIntGravatar letouzey2009-11-18
| | | | | | | | | | | | | | | | | | NZBase -- NZAdd -- NZMul | | NZOrder ---------- NZAddOrder -- NZMulOrder -- NZProperties This is done by transforming NZBase into a functorial module type, and making NZAdd NZMul NZOrder accept an instance of NZBase as parameter. This is possible thanks to a combination of various new features of modules: - interactive proofs in module type (ie functors can be turned into type functors) - Include Type in Module (ie type functors can be turned into functors) - Include Self, <+ , etc, etc... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12534 85f007b7-540e-0410-9357-904b9bb8a0f7
* New syntax <+ for chains of Include (or Include Type) (or Include Self (Type))Gravatar letouzey2009-11-16
| | | | | | | | | | | | | | | | | | | | "Module M (...) := M1 <+ M2 <+ M3 <+ ..." is now a shortcut for "Module M (...). Include M1. Include M2. Include M3... End M." Moreover M2,M3,etc can be functors as long as they find what they need in what comes before them (see new command "Include Self"). The only real constraint is that M1,M2,M3,... should not have common elements (for the moment (?)). Same behavior for signature : Module Type M := M1 <+ M2 <+ M3. Note that this <+ is _not_ a primitive construct of the module language, for instance it cannot be used in signature (Module M <: M1 <+ M2 is illegal for the moment).

* Simplification of Numbers, mainly thanks to IncludeGravatar letouzey2009-11-10
| | | | | | | | | | | | | | | | | - No more nesting of Module and Module Type, we rather use Include. - Instead of in-name-qualification like NZeq, we use uniform short names + modular qualification like N.eq when necessary. - Many simplification of proofs, by some autorewrite for instance - In NZOrder, we instantiate an "order" tactic. - Some requirements in NZAxioms were superfluous: compatibility of le, min and max could be derived from the rest. - NMul removed, since it was containing only an ad-hoc result for ZNatPairs, that we've inlined in the proof of mul_wd there. - Zdomain removed (was already not compiled), idea of a module with eq and eqb reused in DecidableType.BooleanEqualityType. - ZBinDefs don't contain any definition now, migrate it to ZBinary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12489 85f007b7-540e-0410-9357-904b9bb8a0f7
