(This command must + be manually interrupted once the build finishes all the way though. + Note also that this method is not fail-proof; you may have to adjust + some scopes if you were relying on string notations not being + available even when `string_scope` was open.) + +- Numeral syntax for `nat` is no longer available without loading the + entire prelude (`Require Import Coq.Init.Prelude`). This only + impacts users running Coq without the init library (`-nois` or + `-noinit`) and also issuing `Require Import Coq.Init.Datatypes`. + +Tools + +- Coq_makefile lets one override or extend the following variables from + the command line: `COQFLAGS`, `COQCHKFLAGS`, `COQDOCFLAGS`. + `COQFLAGS` is now entirely separate from `COQLIBS`, so in custom Makefiles + `$(COQFLAGS)` should be replaced by `$(COQFLAGS) $(COQLIBS)`. + +- Removed the `gallina` utility (extracts specification from Coq vernacular files). + If you would like to maintain this tool externally, please contact us. + +- Removed the Emacs modes distributed with Coq.

If you want the previous behavior, use `Global Set SsrHave + NoTCResolution`. +- Multiple sections with the same name are allowed. + +Coq binaries and process model + +- Before 8.9, Coq distributed a single `coqtop` binary and a set of + dynamically loadable plugins that used to take over the main loop + for tasks such as IDE language server or parallel proof checking. + + These plugins have been turned into full-fledged binaries so each + different process has associated a particular binary now, in + particular `coqidetop` is the CoqIDE language server, and + `coq{proof,tactic,query}worker` are in charge of task-specific and + parallel proof checking. + +SSReflect + +- The implementation of delayed clear switches in intro patterns + is now simpler to explain: + 1. The immediate effect of a clear switch like `{x}` is to rename the + variable `x` to `_x_` (i.e. a reserved identifier that cannot be mentioned + explicitly) + 2. The delayed effect of `{x}` is that `_x_` is cleared at the end of the intro + pattern + 3. A clear switch immediately before a view application like `{x}/v` is + translated to `/v{x}`. + + In particular, the third rule lets one write `{x}/v` even if `v` uses the variable `x`: + indeed the view is executed before the renaming. + +- An empty clear switch is now accepted in intro patterns before a + view application whenever the view is a variable. + One can now write `{}/v` to mean `{v}/v`. Remark that `{}/x` is very similar + to the idiom `{}e` for the rewrite tactic (the equation `e` is used for + rewriting and then discarded). + +Standard Library + +- There are now conversions between `string` and `positive`, `Z`, + `nat`, and `N` in binary, octal, and hex. + +Display diffs between proof steps + +- `coqtop` and `coqide` can now highlight the differences between proof steps + in color.

This is done via -the V8only option as follows: - -Infix 3 "@" app V8only "@@" (at level 40, left associativity). - -or, alternatively by - -Notation "x @ y" := (app x y) (at level 3, left associativity) - V8only "x @@ y" (at level 40, left associativity). - -b3) My notation is already defined at another level (or with another -associativity) - -In V8, the level and associativity of a given notation can no longer -be changed. Then, either you adopt the standard reserved levels and -associativity for this notation (as given on the list above) or you -change your notation. - -- To change the notation, follow the directions in section b2. - -- To adopt the standard level, just use V8only without any argument. - -Example. - -Infix 6 "*" my_mult. - -is not accepted as such in V8. Write - -Infix 6 "*" my_mult V8only. - -to tell the translator to use "*" at the reserved level (i.e. 40 with -left associativity). Even better, use interpretation scopes (look at -the Reference Manual). - -c) How to use V8only with Distfix ? - -You can't, use Notation instead of Distfix. - -d) Can I overload a notation in V8, e.g. use "*" and "+" for my own -algebraic operations ? - -Yes, using interpretation scopes (see the corresponding chapter in the -Reference Manual). - -3) Using the translator to have simplest notations - -Thanks to the new syntax, * has now the expected left associativity, -and the symbols <, >, <= and >= are now available. - -Thanks to the interpretation scopes, you can overload the -interpretation of these operators with the default interpretation -provided in Coq. - -This may be a motivation to use the translator to automatically change -the notations while switching to the new syntax. - -See sections b) and d) above for examples. - -4) Setting the translator to automatically use new notations that -wasn't used in old syntax - -Thanks to the "Notation" mechanism, defining symbolic notations is -simpler than in the previous versions of Coq. - -Thanks to the new syntax and interpretation scopes, new symbols and -overloading is available. - -This may be a motivation for using the translator to automatically change -the notations while switching to the new syntax. - -Use for that the commands V8Notation and V8Infix. - -Examples: - -V8Infix "==>" my_relation (at level 65, right associativity). - -tells the translator to write an infix "==>" instead of my_relation in -the translated files. - -V8Infix ">=" my_ge. - -tells the translator to write an infix ">=" instead of my_ge in the -translated files and that the level and associativity are the standard -one (as defined in the chart above). - -V8Infix ">=" my_ge : my_scope. - -tells the translator to write an infix ">=" instead of my_ge in the -translated files, that the level and associativity are the standard -one (as defined in the chart above), but only if scope my_scope is -open or if a delimiting key is available for "my_scope" (see the -Reference Manual). - -5) Defining a construction and its notation simultaneously - -This is permitted by the new syntax. Look at the Reference Manual for -explanation. The translator is not fully able to take this in charge... - -III) Various pitfalls - ---------------- - -1) New keywords - - The following identifiers are new keywords - - "forall"; "fun"; "match"; "fix"; "cofix"; "for"; "if"; "then"; - "else"; "return"; "mod"; "at"; "let"; "_"; ".(" - - The translator automatically add a "_" to names clashing with a -keyword, except for files. Hence users may need to rename the files -whose name clashes with a keyword. - - Remark: "in"; "with"; "end"; "as"; "Prop"; "Set"; "Type" - were already keywords - -2) Old "Case" and "Match" - - "Case" and "Match" are normally automatically translated into - "match" or "match" and "fix", but sometimes it fails to do so. It - typically fails when the Case or Match is argument of a tactic whose - typing context is unknown because of a preceding Intro/Intros, as e.g. in - - Intros; Exists [m:nat](<quasiterm>Case m of t [p:nat](f m) end) - - The solution is then to replace the invocation of the sequence of - tactics into several invocation of the elementary tactics as follows - - Intros. Exists [m:nat](<quasiterm>Case m of t [p:nat](f m) end) - ^^^ - -3) Change of definition or theorem names - - Type "entier" from fast_integer.v is renamed into "N" by the -translator. As a consequence, user-defined objects of same name "N" -are systematically qualified even tough it may not be necessary. The -same apply for names "GREATER", "EQUAL", "LESS", etc... [COMPLETE LIST -TO GIVE]. - -4) Change of tactics names - - Since tactics names are now lowercase, this can clash with -user-defined tactic definitions. To pally this, clashing names are -renamed by adding an extra "_" to their name. - -====================================================================== -Main examples for new syntax ----------------------------- - -1) Constructions - - Applicative terms don't any longer require to be surrounded by parentheses as -e.g in - - "x = f y -> S x = S (f y)" - - - Product is written - - "forall x y : T, U" - "forall x y, U" - "forall (x y : T) z (v w : V), U" - etc. - - Abstraction is written - - "fun x y : T, U" - "fun x y, U" - "fun (x y : T) z (v w : V), U" - etc. - - Pattern-matching is written - - "match x with c1 x1 x2 => t | c2 y as z => u end" - "match v1, v2 with c1 x1 x2, _ => t | c2 y, d z => u end" - "match v1 as y in le _ n, v2 as z in I p q return P n y p q z with - c1 x1 x2, _ => t | c2 y, d z => u end" - - The last example is the new form of what was written - - "<[n;y:(le ? n);p;q;z:(I p q)](P n y p q z)>Cases v1 v2 of - (c1 x1 x2) _ => t | (c2 y) (d z) => u end" - - Pattern-matching of type with one constructors and no dependencies -of the arguments in the resulting type can be written - - "let (x,y,z) as u return P u := t in v" - - Local fixpoints are written - - "fix f (n m:nat) z (x : X) {struct m} : nat := ... - with ..." - - and "struct" tells which argument is structurally decreasing. - - Explicitation of implicit arguments is written - - "f @1:=u v @3:=w t" - "@f u v w t" - -2) Tactics - - The main change is that tactics names are now lowercase. Besides -this, the following renaming are applied: - - "NewDestruct" -> "destruct" - "NewInduction" -> "induction" - "Induction" -> "simple induction" - "Destruct" -> "simple destruct" - - For tactics with occurrences, the occurrences now comes after and - repeated use is separated by comma as in - - "Pattern 1 3 c d 4 e" -> "pattern c at 3 1, d, e at 4" - "Unfold 1 3 f 4 g" -> "unfold f at 1 3, g at 4" - "Simpl 1 3 e" -> "simpl e at 1 3" - -3) Tactic language - - Definitions are now introduced with keyword "Ltac" (instead of -"Tactic"/"Meta" "Definition") and are implicitly recursive -("Recursive" is no longer used). - - The new rule for distinguishing terms from ltac expressions is: - - Write "ltac:" in front of any tactic in argument position and - "constr:" in front of any construction in head position - -4) Vernacular language - -a) Assumptions - - The syntax for commands is mainly unchanged. Declaration of -assumptions is now done as follows - - Variable m : t. - Variables m n p : t. - Variables (m n : t) (u v : s) (w : r). - -b) Definitions - - Definitions are done as follows - - Definition f m n : t := ... . - Definition f m n := ... . - Definition f m n := ... : t. - Definition f (m n : u) : t := ... . - Definition f (m n : u) := ... : t. - Definition f (m n : u) := ... . - Definition f a b (p q : v) r s (m n : t) : t := ... . - Definition f a b (p q : v) r s (m n : t) := ... . - Definition f a b (p q : v) r s (m n : t) := ... : t. - -c) Fixpoints - - Fixpoints are done this way - - Fixpoint f x (y : t) z a (b c : u) {struct z} : v := ... with ... . - Fixpoint f x : v := ... . - Fixpoint f (x : t) : v := ... . - - It is possible to give a concrete notation to a fixpoint as follows - - Fixpoint plus (n m:nat) {struct n} : nat as "n + m" := - match n with - | O => m - | S p => S (p + m) - end. - -d) Inductive types - - The syntax for inductive types is as follows - - Inductive t (a b : u) (d : e) : v := - c1 : w1 | c2 : w2 | ... . - - Inductive t (a b : u) (d : e) : v := - c1 : w1 | c2 : w2 | ... . - - Inductive t (a b : u) (d : e) : v := - c1 (x y : t) : w1 | c2 (z : r) : w2 | ... . - - As seen in the last example, arguments of the constructors can be -given before the colon.

As + with altP, my_formula must be an application. + \unless C, P <-> we can assume property P when a something that + holds under condition C (such as C itself). + := forall G : Prop, (C -> G) -> (P -> G) -> G. + This is just C \/ P or rather its impredicative + encoding, whose usage better fits the above + description: given a lemma UCP whose conclusion + is \unless C, P we can assume P by writing: + wlog hP: / P by apply/UCP; (prove C -> goal). + or even apply: UCP id _ => hP if the goal is C. + classically P <-> we can assume P when proving is_true b. + := forall b : bool, (P -> b) -> b. + This is equivalent to ~ (~ P) when P : Prop. + implies P Q == wrapper variant type that coerces to P -> Q and + can be used as a P -> Q view unambigously. + Useful to avoid spurious insertion of <-> views + when Q is a conjunction of foralls, as in Lemma + all_and2 below; conversely, avoids confusion in + apply views for impredicative properties, such + as \unless C, P. Also supports contrapositives. + a && b == the boolean conjunction of a and b. + a || b == the boolean disjunction of a and b. + a ==> b == the boolean implication of b by a. + ~~ a == the boolean negation of a. + a (+) b == the boolean exclusive or (or sum) of a and b. + #[# /\ P1 , P2 & P3 #]# == multiway logical conjunction, up to 5 terms. + #[# \/ P1 , P2 | P3 #]# == multiway logical disjunction, up to 4 terms. + #[#&& a, b, c & d#]# == iterated, right associative boolean conjunction + with arbitrary arity. + #[#|| a, b, c | d#]# == iterated, right associative boolean disjunction + with arbitrary arity. + #[#==> a, b, c => d#]# == iterated, right associative boolean implication + with arbitrary arity. + and3P, ... == specific reflection lemmas for iterated + connectives. + andTb, orbAC, ... == systematic names for boolean connective + properties (see suffix conventions below). + prop_congr == a tactic to move a boolean equality from + its coerced form in Prop to the equality + in bool. + bool_congr == resolution tactic for blindly weeding out + like terms from boolean equalities (can fail). + This file provides a theory of boolean predicates and relations: + pred T == the type of bool predicates (:= T -> bool). + simpl_pred T == the type of simplifying bool predicates, using + the simpl_fun from ssrfun.v. + rel T == the type of bool relations. + := T -> pred T or T -> T -> bool. + simpl_rel T == type of simplifying relations. + predType == the generic predicate interface, supported for + for lists and sets. + pred_class == a coercion class for the predType projection to + pred; declaring a coercion to pred_class is an + alternative way of equipping a type with a + predType structure, which interoperates better + with coercion subtyping. This is used, e.g., + for finite sets, so that finite groups inherit + the membership operation by coercing to sets. + If P is a predicate the proposition "x satisfies P" can be written + applicatively as (P x), or using an explicit connective as (x \in P); in + the latter case we say that P is a "collective" predicate. We use A, B + rather than P, Q for collective predicates: + x \in A == x satisfies the (collective) predicate A. + x \notin A == x doesn't satisfy the (collective) predicate A. + The pred T type can be used as a generic predicate type for either kind, + but the two kinds of predicates should not be confused. When a "generic" + pred T value of one type needs to be passed as the other the following + conversions should be used explicitly: + SimplPred P == a (simplifying) applicative equivalent of P. + mem A == an applicative equivalent of A: + mem A x simplifies to x \in A. + Alternatively one can use the syntax for explicit simplifying predicates + and relations (in the following x is bound in E): + #[#pred x | E#]# == simplifying (see ssrfun) predicate x => E. + #[#pred x : T | E#]# == predicate x => E, with a cast on the argument. + #[#pred : T | P#]# == constant predicate P on type T. + #[#pred x | E1 & E2#]# == #[#pred x | E1 && E2#]#; an x : T cast is allowed. + #[#pred x in A#]# == #[#pred x | x in A#]#. + #[#pred x in A | E#]# == #[#pred x | x in A & E#]#. + #[#pred x in A | E1 & E2#]# == #[#pred x in A | E1 && E2#]#. + #[#predU A & B#]# == union of two collective predicates A and B. + #[#predI A & B#]# == intersection of collective predicates A and B. + #[#predD A & B#]# == difference of collective predicates A and B. + #[#predC A#]# == complement of the collective predicate A. + #[#preim f of A#]# == preimage under f of the collective predicate A. + predU P Q, ... == union, etc of applicative predicates. + pred0 == the empty predicate. + predT == the total (always true) predicate. + if T : predArgType, then T coerces to predT. + {: T} == T cast to predArgType (e.g., {: bool * nat}) + In the following, x and y are bound in E: + #[#rel x y | E#]# == simplifying relation x, y => E. + #[#rel x y : T | E#]# == simplifying relation with arguments cast. + #[#rel x y in A & B | E#]# == #[#rel x y | #[#&& x \in A, y \in B & E#]# #]#. + #[#rel x y in A & B#]# == #[#rel x y | (x \in A) && (y \in B) #]#. + #[#rel x y in A | E#]# == #[#rel x y in A & A | E#]#. + #[#rel x y in A#]# == #[#rel x y in A & A#]#. + relU R S == union of relations R and S. + Explicit values of type pred T (i.e., lamdba terms) should always be used + applicatively, while values of collection types implementing the predType + interface, such as sequences or sets should always be used as collective + predicates. Defined constants and functions of type pred T or simpl_pred T + as well as the explicit simpl_pred T values described below, can generally + be used either way. Note however that x \in A will not auto-simplify when + A is an explicit simpl_pred T value; the generic simplification rule inE + must be used (when A : pred T, the unfold_in rule can be used). Constants + of type pred T with an explicit simpl_pred value do not auto-simplify when + used applicatively, but can still be expanded with inE. This behavior can + be controlled as follows: + Let A : collective_pred T := #[#pred x | ... #]#. + The collective_pred T type is just an alias for pred T, but this cast + stops rewrite inE from expanding the definition of A, thus treating A + into an abstract collection (unfold_in or in_collective can be used to + expand manually). + Let A : applicative_pred T := #[#pred x | ... #]#. + This cast causes inE to turn x \in A into the applicative A x form; + A will then have to unfolded explicitly with the /A rule. This will + also apply to any definition that reduces to A (e.g., Let B := A). + Canonical A_app_pred := ApplicativePred A. + This declaration, given after definition of A, similarly causes inE to + turn x \in A into A x, but in addition allows the app_predE rule to + turn A x back into x \in A; it can be used for any definition of type + pred T, which makes it especially useful for ambivalent predicates + as the relational transitive closure connect, that are used in both + applicative and collective styles. + Purely for aesthetics, we provide a subtype of collective predicates: + qualifier q T == a pred T pretty-printing wrapper. An A : qualifier q T + coerces to pred_class and thus behaves as a collective + predicate, but x \in A and x \notin A are displayed as: + x \is A and x \isn't A when q = 0, + x \is a A and x \isn't a A when q = 1, + x \is an A and x \isn't an A when q = 2, respectively. + #[#qualify x | P#]# := Qualifier 0 (fun x => P), constructor for the above. + #[#qualify x : T | P#]#, #[#qualify a x | P#]#, #[#qualify an X | P#]#, etc. + variants of the above with type constraints and different + values of q. + We provide an internal interface to support attaching properties (such as + being multiplicative) to predicates: + pred_key p == phantom type that will serve as a support for properties + to be attached to p : pred_class; instances should be + created with Fact/Qed so as to be opaque. + KeyedPred k_p == an instance of the interface structure that attaches + (k_p : pred_key P) to P; the structure projection is a + coercion to pred_class. + KeyedQualifier k_q == an instance of the interface structure that attaches + (k_q : pred_key q) to (q : qualifier n T). + DefaultPredKey p == a default value for pred_key p; the vernacular command + Import DefaultKeying attaches this key to all predicates + that are not explicitly keyed. + Keys can be used to attach properties to predicates, qualifiers and + generic nouns in a way that allows them to be used transparently. The key + projection of a predicate property structure such as unsignedPred should + be a pred_key, not a pred, and corresponding lemmas will have the form + Lemma rpredN R S (oppS : @opprPred R S) (kS : keyed_pred oppS) : + {mono -%%R: x / x \in kS}. + Because x \in kS will be displayed as x \in S (or x \is S, etc), the + canonical instance of opprPred will not normally be exposed (it will also + be erased by /= simplification). In addition each predicate structure + should have a DefaultPredKey Canonical instance that simply issues the + property as a proof obligation (which can be caught by the Prop-irrelevant + feature of the ssreflect plugin). + Some properties of predicates and relations: + A =i B <-> A and B are extensionally equivalent. + {subset A <= B} <-> A is a (collective) subpredicate of B. + subpred P Q <-> P is an (applicative) subpredicate or Q. + subrel R S <-> R is a subrelation of S. + In the following R is in rel T: + reflexive R <-> R is reflexive. + irreflexive R <-> R is irreflexive. + symmetric R <-> R (in rel T) is symmetric (equation). + pre_symmetric R <-> R is symmetric (implication). + antisymmetric R <-> R is antisymmetric. + total R <-> R is total. + transitive R <-> R is transitive. + left_transitive R <-> R is a congruence on its left hand side. + right_transitive R <-> R is a congruence on its right hand side. + equivalence_rel R <-> R is an equivalence relation. + Localization of (Prop) predicates; if P1 is convertible to forall x, Qx, + P2 to forall x y, Qxy and P3 to forall x y z, Qxyz : + {for y, P1} <-> Qx{y / x}. + {in A, P1} <-> forall x, x \in A -> Qx. + {in A1 & A2, P2} <-> forall x y, x \in A1 -> y \in A2 -> Qxy. + {in A &, P2} <-> forall x y, x \in A -> y \in A -> Qxy. + {in A1 & A2 & A3, Q3} <-> forall x y z, + x \in A1 -> y \in A2 -> z \in A3 -> Qxyz. + {in A1 & A2 &, Q3} == {in A1 & A2 & A2, Q3}. + {in A1 && A3, Q3} == {in A1 & A1 & A3, Q3}. + {in A &&, Q3} == {in A & A & A, Q3}. + {in A, bijective f} == f has a right inverse in A. + {on C, P1} == forall x, (f x) \in C -> Qx + when P1 is also convertible to Pf f. + {on C &, P2} == forall x y, f x \in C -> f y \in C -> Qxy + when P2 is also convertible to Pf f. + {on C, P1' & g} == forall x, (f x) \in cd -> Qx + when P1' is convertible to Pf f + and P1' g is convertible to forall x, Qx. + {on C, bijective f} == f has a right inverse on C. + This file extends the lemma name suffix conventions of ssrfun as follows: + A -- associativity, as in andbA : associative andb. + AC -- right commutativity. + ACA -- self-interchange (inner commutativity), e.g., + orbACA : (a || b) || (c || d) = (a || c) || (b || d). + b -- a boolean argument, as in andbb : idempotent andb. + C -- commutativity, as in andbC : commutative andb, + or predicate complement, as in predC. + CA -- left commutativity. + D -- predicate difference, as in predD. + E -- elimination, as in negbFE : ~~ b = false -> b. + F or f -- boolean false, as in andbF : b && false = false. + I -- left/right injectivity, as in addbI : right_injective addb, + or predicate intersection, as in predI. + l -- a left-hand operation, as andb_orl : left_distributive andb orb. + N or n -- boolean negation, as in andbN : a && (~~ a) = false. + P -- a characteristic property, often a reflection lemma, as in + andP : reflect (a /\ b) (a && b). + r -- a right-hand operation, as orb_andr : rightt_distributive orb andb. + T or t -- boolean truth, as in andbT: right_id true andb. + U -- predicate union, as in predU. + W -- weakening, as in in1W : {in D, forall x, P} -> forall x, P. **) + Set Implicit Arguments.
